Introduction 1.1 ST overview This document is the sanitized version of the document Security Target for CELES-c002 Machine Readable Electronic Document – ICAO Application – EAC-PACE-AA [R19]. This Security Target (ST) document defines the security objectives and requirements, as well as the scope of the Common Criteria evaluation of CELES-c002 Machine Readable Electronic Document. The Target Of Evaluation (TOE) is the integrated circuit chip NXP N7121 equipped with the IC Dedicated Software and Crypto Library, the operating system CELES-c002 and with e- Document applications, namely an International Civil Aviation Organization (ICAO) application compliant with ICAO Doc 9303 [R29] [R30] [R31], and an eIDAS Qualified Signature Creation Device (QSCD) application providing signature features and encrypted data decipherment feature. The signature features are compliant with the eIDAS Regulation (EU) No 910/2014 [R13] and the according Commission Implementing Decision (EU) 2016/650 [R14], repealing the European Parliament Directive 1999/93/EC [R15]. The eIDAS QSCD application can optionally be configured as a PKCS #15 application [R52]. The TOE adds security features to a document booklet or card, providing machine-assisted identity confirmation and machine-assisted verification of document security, as well as secure signature creation and data encipherment. This ST addresses the following advanced security mechanisms featured by the ICAO application: • Extended Access Control (EAC) v1, which includes Chip Authentication according to ICAO Doc 9303 7th ed. Part 11 [R30], and Terminal Authentication according to BSI TR-03110 [R6] [R7], • Password Authenticated Connection Establishment (PACE) according to ICAO Doc 9303 7th ed. Part 11 [R30] • Active Authentication according to ICAO Doc 9303 7th ed. 2015 Part 11 [R30]. The TOE also supports Basic Access Control (BAC) compliant with ICAO Doc 9303 [R30], addressed by another ST [R17] [R18]. The eIDAS QSCD application requirements are addressed by still another ST [R20] [R21].

The TOE is delivered as a chip ready for pre-personalization. It is identified by the following string, which constitutes the TOE identifier: CELES-c002_1 (ASCII codes 43h 45h 4Ch 45h 53h 2Dh 63h 30h 30h 32h 5Fh 31h) where: • “CELES-c002” is the TOE name, • the underscore character is a separator, and • “1” is the TOE version number. The ASCII encoding of the TOE identifier constitutes the TOE identification data, located in the persistent memory of the chip. Instructions for reading these data are provided by the guidance documentation [R22] [R23] [R24] [R25] [R26] [R27]. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 15 of 177 1.4 TOE overview 1.4.1 TOE definition The TOE is the integrated circuit chip of a machine readable e-Document programmed according to the Password Authenticated Connection Establishment mechanism described in the ICAO Doc 9303 Part 11 [R30], which means amongst others according to the Logical Data Structure (LDS) defined in [R29], and additionally providing the Extended Access Control according to the ICAO Doc 9303-11 [R30] and BSI TR-03110 [R6] [R7]. The TOE is composed of: • the circuitry of the dual-interface e-Document’s chip NXP N7121 (see Appendix A), • the IC Dedicated Software with the parts IC Dedicated Test Software and IC Dedicated Support Software, and Crypto Library • the smart card operating system CELES-c002, • an ICAO application compliant with ICAO Doc 9303 [R29] [R30] [R31], • an eIDAS QSCD application compliant with the eIDAS Regulation (EU) No 910/2014 [R13] and the according Commission Implementing Decision (EU) 2016/650 [R14], repealing the European Parliament Directive 1999/93/EC [R15] (this application is not in the scope of this ST), • the associated guidance documentation [R22] [R23] [R24] [R25] [R26] [R27]. On account of its composite nature, the TOE evaluation builds on the evaluation of the integrated circuit. The TOE supports wired communication through the IC contacts exposed to the outside, as well as wireless communication through an antenna connected to the IC. Both the TOE and the antenna are embedded in a paper or plastic substrate, that provides mechanical support and protection. Once personalized with the data of the legitimate holder and with security data, the e- Document can be inspected by authorized agents. The TOE is meant for “global interoperability”. According to ICAO the term is understood as “the capability of inspection systems (either manual or automated) in different States throughout the world to exchange data, to process data received from systems in other States, and to utilize that data in inspection operations in their respective States”. The TOE is supplied with a file system that contains all the data used in the context of the ICAO application, as described in the Protection Profiles [R4] [R5]. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 16 of 177 1.4.2 TOE usage and security features for operational use A State or Organization issues e-Documents to be used by the holder. The user presents an e-Document to the inspection system to prove his or her identity. Being the TOE a general-purpose e-Document, it supports both the following types of PACE passwords: • non-secret passwords not deducible from the logical document, at least without a previous PACE authentication, but printed or displayed on the physical document (e.g. MRZ or CAN as in the case of a PACE e-Passport [R30]); • secret passwords not deducible from either the logical document, at least without a previous PACE authentication, or the physical document. For the ICAO application, the document holder can control access to his user data by consciously presenting his document to organizations deputed to perform inspection1. In the case of a secret PACE password, the document holder can exert further control over access to his data as in addition to his document, he must separately reveal the password in order to authorize inspection. The document’s chip is integrated into a physical (plastic or paper) substrate. The substrate is not part of the TOE. The tying-up of the document’s chip to the plastic/paper document is achieved in accordance with physical and organizational security measures being within the scope of the current security target. The e-Document in context of this security target contains: i. data elements on the e-Document’s chip according to LDS for contactless or contact machine reading. Additionally, the e-Document may bear: ii. visual (eye readable) biographical data and portrait of the holder, iii. a separate data summary (MRZ data) for visual and machine reading using OCR methods in the Machine Readable Zone (MRZ). The authentication of the presenter2 is based on: • the possession of a valid e-Document personalized with the claimed identity as given on the biographical data page, and • biometrics using the reference data stored in the e-Document. 1 User authentication with PACE password, such as CAN or MRZ or shared secret, see [R30]. 2 The person presenting the e-Document to the Inspection System. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 17 of 177 The Issuing State or Organization ensures the authenticity of the data of genuine e- Documents. The receiving state trusts a genuine e-Document of an Issuing State or Organization. For this security target, the e-Document is viewed as the unit of: • the physical part of the electronic document in form of paper and/or plastic and chip. It presents visual readable data including (but not limited to) personal data of the e-Document holder: i. the biographical data on the biographical data page of the data surface, ii. the printed data in the Machine Readable Zone (MRZ), iii. the printed portrait; • the logical e-Document as data of the e-Document holder stored according to the Logical Data Structure [R29] as specified by ICAO on the integrated circuit. It presents machine readable data including (but not limited to) personal data of the e- Document holder: i. the digital Machine Readable Zone Data (digital MRZ data, EF.DG1), ii. the digitized portraits (EF.DG2), iii. the biometric reference data of finger(s) (EF.DG3) or iris image(s) (EF.DG4) or both3, iv. the other data according to LDS (EF.DG5 to EF.DG16), v. the Document Security Object (SOD), vi. security data objects required for product management. The Issuing State or Organization implements security features of the e-Document to maintain the authenticity and integrity of the e-Document and its data. The physical part of the e-Document as the e-Document’s chip are uniquely identified by the Document Number. The physical part of the e-Document is protected by physical security measures (e.g. watermark, security printing), logical (e.g. authentication keys of the e-Document’s chip) and organizational security measures (e.g. control of materials, personalization procedure). These security measures can include the binding of the e-Document's chip to the e- Document. The logical e-Document delivered by the IC Manufacturer to the Pre-personalization Agent is protected by a mutual authentication mechanism based on symmetric cryptography with 3 These biometric reference data are optional according to [R29]. This ST assumes that the issuing State or Organization uses this option and protects these data by means of extended access control. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 18 of 177 diversified key, until completion of the pre-personalization process. After completion, the authentication keys are disabled. The logical e-Document is protected in authenticity and integrity by a digital signature created by the document signer acting for the issuing State or Organization and the security features of the e-Document’s chip. The ICAO defines the baseline required security methods Passive Authentication and the following optional advanced security methods: • Basic Access Control to the logical e-Document, • Active Authentication of the e-Document’s chip, • Extended Access Control to and the Data Encryption of sensitive biometrics as an optional security measure in the ICAO Doc 9303-11 [R30], and • Password Authenticated Connection Establishment [R30]. The Passive Authentication mechanism is performed completely and independently of the TOE by the TOE environment. This security target addresses the protection of the logical e-Document: i. in integrity by write-only-once access control and by physical means, and ii. in confidentiality by the Extended Access Control Mechanism. As BAC is also supported by the TOE, the e-Document has to be evaluated and certified separately. This is due to the fact that [R3] does only consider extended basic attack potential to the Basic Access Control Mechanism (i.e. AVA_VAN.3). The confidentiality by Password Authenticated Access Control (PACE) is a mandatory security feature of the TOE. The e-Document shall strictly conform to the “Common Criteria Protection Profile Machine Readable Travel Document using Standard Inspection Procedure with PACE (PACE PP)” [R5]. Note that [R5] considers high attack potential. The TOE supports PACE with Generic Mapping (PACE-GM), with Integrated Mapping (PACE-IM), and with Chip Authentication Mapping (PACE-CAM). For the PACE protocol according to [R30], the following steps shall be performed: i. The e-Document’s chip encrypts a nonce with the shared password, derived from the PACE password (MRZ, CAN or secret password) and transmits the encrypted nonce together with the domain parameters to the terminal. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 19 of 177 ii. The terminal recovers the nonce using the shared password. If this password is derived from MRZ or CAN, MRZ data or CAN data are physically read. iii. The e-Document’s chip and terminal computer perform a Diffie-Hellman key agreement together with the ephemeral domain parameters to create a shared secret. Both parties derive the session keys KMAC and KENC from the shared secret. iv. Each party generates an authentication token, sends it to the other party and verifies the received token. Additionally, for PACE-CAM only, the following steps shall be performed: v. the e-Document computes Chip Authentication Data, encrypts them, and sends them to the terminal; vi. the terminal recovers Chip Authentication Data and verifies the authenticity of the chip. After successful key negotiation, the terminal and the e-Document’s chip provide private communication (secure messaging) [R5] [R30]. This security target requires the TOE to implement the Extended Access Control as defined in [R6] [R7], and additionally the Active Authentication as defined in [R30]. The Extended Access Control consists of two parts: (i) the Chip Authentication and (ii) the Terminal Authentication Protocol version 1 (v.1). The Chip Authentication may be performed as part of the PACE protocol (see steps v. and vi. above), or as a distinct protocol (Chip Authentication Protocol version 1). Both modes are detailed in section 4.4 of ICAO Doc 9303 Part 11 [R30]. The Chip Authentication (i) authenticates the e-Document’s chip to the inspection system, and (ii) establishes secure messaging which is used by Terminal authentication v.1 to protect the confidentiality and integrity of the sensitive biometric reference data during their transmission from the TOE to the inspection system. Therefore, Terminal Authentication v.1 can only be performed if either PACE-CAM or Chip Authentication Protocol v.1 have been successfully executed. The Terminal Authentication Protocol v.1 consists of (i) the authentication of the inspection system as entity authorized by the receiving State or Organization through the issuing State, and (ii) an access control by the TOE to allow reading the sensitive biometric reference data only to successfully authenticated inspection systems. The issuing State or Organization authorizes the receiving State by means of certification the authentication public keys of Document Verifiers who create Inspection System Certificates. The Active Authentication authenticates the e-Document to the inspection system. 1.4.3 Non-TOE hardware/software/firmware required by the TOE There is no explicit non-TOE hardware, software or firmware required by the TOE to perform its claimed security features. The TOE is defined to comprise the chip and the complete CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 20 of 177 operating system and application. Note that the substrate holding the chip as well as the antenna (if any) and the card are needed to represent a complete e-Document, nevertheless these parts are not essential for the secure operation of the TOE. 1.5 TOE life cycle The TOE life cycle is comprised of four life cycle phases, i.e. development, manufacturing, personalization, and operational use. With regard to the life cycle of the ICAO application, these phases can be split into seven steps as follows: 1. Phase 1: Development comprises: Step 1: the development of the integrated circuit and IC dedicated software by the IC Manufacturer, and Step 2: the development of the operating system software by the Embedded Software Developer; 2. Phase 2: Manufacturing comprises: Step 3: the fabrication of the integrated circuit by the IC Manufacturer, Step 4: the embedding of the chip in a substrate with an antenna. The antenna may be omitted if the IC contacts are exposed, Step 5: the pre-personalization of the e-Document; 3. Phase 3: Personalization comprises: Step 6: the personalization of the e-Document for the holder; 4. Phase 4: Operational use comprises: Step 7: the inspection of the e-Document. Application Note 1 The entire development phase, as well as step 3, “Manufacture of the IC”, of the manufacturing phase are the only phases covered by assurance under ALC, as during these phases the TOE is under construction in a protected environment. Figure 1-1 represents the life cycle of the ICAO application. Particularly, it identifies the actors involved in each step of the life cycle. Direct deliveries of items between actors are represented with continuous lines, while deliveries in which intermediate actors may be in charge of receiving the exchanged items and forwarding them to the subsequent actors are represented with dotted lines. Deliveries of items occurring between non-consecutive actors are just marked with letters in order to preserve the clarity of the diagram. A legend for these deliveries, which identifies the exchanged items for each of them, is provided in Table 1-3.

Table 1-5 identifies, for each guidance document, the actors who are the intended recipients of that item. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 24 of 177 Table 1-5 Identification of recipient actors for the guidance documentation of the TOE ICAO application Guidance document Recipient actors Pre-personalization guidance Pre-personalization Agent Personalization guidance Personalization Agent Operational user guidance Inspection System The phases and steps of the TOE life cycle are described in what follows. The names of the involved actors are emphasized using boldface. 1.5.1 Phase 1: Development Step 1: Development of the IC and the IC Dedicated Software The IC Developer develops the integrated circuit, the IC Dedicated Software, and the guidance documentation associated with these TOE components. Finally, the following items are securely delivered to the Embedded Software Developer and the IC Manufacturer: • the IC manufacturing documentation, • the IC Dedicated Software. Step 2: Development of the Embedded Software The Embedded Software Developer uses the guidance documentation for the integrated circuit and for relevant parts of the IC Dedicated Software and develops the Embedded Software, consisting of the OS, the ICAO application, and the eIDAS QSCD application, as well as the guidance documentation associated with these TOE components. Furthermore, the Embedded Software Developer generates the pre-personalization key. Finally: • the Embedded Software and the pre-personalization key are securely delivered to the IC Manufacturer; • the pre-personalization key is securely delivered to the Pre-personalization Agent. As regards TOE guidance documentation, either all documents are securely delivered to the Pre-personalization Agent, or each document is securely delivered to the recipient actors as identified in Table 1-5. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 25 of 177 1.5.2 Phase 2: Manufacturing Step 3: Manufacture of the IC The IC Manufacturer produces the TOE integrated circuit, containing the IC Dedicated Software and the Embedded Software, and creates in the IC persistent memory the high- level objects relevant for the ICAO application. Particularly, the pre-personalization key is stored into the IC persistent memory. Finally, the TOE is securely delivered to the Card Manufacturer. Application Note 2 The point of delivery of the TOE coincides with the completion of step 3, i.e. with the delivery of the TOE, in the form of an IC not yet embedded, from the IC Manufacturer to the Card Manufacturer. That is to say, this is the event upon which the construction of the TOE in a secure environment ends, and the TOE begins to be self- protected. Step 4: Manufacture of the smart card or document booklet The Card Manufacturer equips the IC with contact-based and/or contactless interfaces, and embeds the IC into a smart card or a document booklet. Finally, the TOE is securely delivered to the Pre-personalization Agent. Step 5: Pre-personalization The Pre-personalization Agent generates the personalization key, then creates/modifies in the IC persistent memory the high-level objects relevant for the ICAO application. Once the pre-personalization is finished, the TOE and the personalization key are securely delivered to the Personalization Agent. As regards TOE guidance documentation, if the Pre-personalization Agent also received the documents intended for the subsequent actors, then either all of these documents are securely delivered to the Personalization Agent, or each document is securely delivered to the recipient actors as identified in Table 1-5. 1.5.3 Phase 3: Personalization Step 6: Personalization CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 26 of 177 The personalization of the e-Document, performed by the Personalization Agent, includes: (i) the survey of the e-Document holder’s biographical data, (ii) the enrolment of the e-Document holder biometric reference data (i.e. the digitized portraits and the optional biometric reference data), (iii) the personalization of the visual readable data onto the physical part of the e- Document, (iv) the writing of the TOE user data and TSF data into the logical e-Document, and (v) configuration of the TSF if necessary. Step (iv) includes, but is not limited to, the creation of: (i) the digital MRZ data (EF.DG1), (ii) the digitized portrait (EF.DG2), and (iii) the Document Security Object. The signing of the Document Security Object by the Document Signer [R29] [R31] finalizes the personalization of the genuine e-Document for the document holder. Application Note 3 The authenticated Personalization Agent shall additionally verify an Application Secret Code (ASC) to have read access to user data stored in step 5. The personalized e-Document (together with appropriate guidance for TOE use if necessary) is handed over to the e-Document holder for operational use. Application Note 4 The TSF data (data created by and for the TOE, that might affect the operation of the TOE; cf. [R9], section 92) comprise (but are not limited to) the pre- personalization key, the personalization key, and the Basic Access Control key. Application Note 5 This security target distinguishes between the Personalization Agent as an entity known to the TOE and the Document Signer as an entity in the TOE IT environment signing the Document Security Object as described in [R29] and [R31]. This approach allows but does not enforce the separation of these roles. 1.5.4 Phase 4: Operational use Step 7: Inspection The TOE is used as e-Document’s chip by the presenter and the inspection systems in the operational use phase. The user data can be read and used according to the security policy of the issuing state or organization, but can never be modified. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 27 of 177 Application Note 6 This ST considers phase 1 and parts of phase 2 (i.e. step 1 to step 3) as part of the evaluation, and therefore defines the TOE delivery according to CC after step 3. Since specific production steps of phase 2 are of minor security relevance (e.g. card manufacturing and antenna integration), these are not part of the CC evaluation under ALC. Note that the personalization process and its environment may depend on specific security needs of an issuing state or organization. All production, generation, and installation procedures, after TOE delivery up to the operational use (phase 4), have to be considered in the product evaluation process under AGD assurance class. Therefore, this security target outlines the split up of P.Manufact, P.Personalization and the related security objectives into aspects relevant before vs. after TOE delivery. Some production steps, e.g. step 5 in phase 2, may also take place in phase 3. 1.6 TOE description 1.6.1 Physical scope of the TOE The TOE is comprised of the following parts: • dual-interface integrated circuit chip NXP N7121 equipped with IC Dedicated Software and Crypto Library (cf. Appendix A for more details); • smart card operating system CELES-c002; • an International Civil Aviation Organization (ICAO) application compliant with ICAO Doc 9303 [R29] [R30] [R31]; • guidance documentation about the preparation and use of the ICAO application, composed by: o the Pre-personalization Guidance [R22], o the Personalization Guidance [R23], o the Operational User Guidance [R24]. Table 1-5 identifies, for each guidance document, the actors involved in TOE life cycle who are the intended recipients of that document. The TOE is distributed in accordance with the evaluated delivery procedure [R28]. 1.6.2 Other non-TOE physical components The antenna and the substrate are not part of the TOE. Figure 1-2 shows the physical components, distinguishing between TOE components and non-TOE components. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 28 of 177 Figure 1-2 Smart card physical components 1.6.3 Logical scope of the TOE The CELES-c002 operating system manages all the resources of the integrated circuit that equips the e-Document, providing secure access to data and functions. In more detail, in each life cycle phase/step, access to data and functions is restricted by means of cryptographic mechanisms as follows: • In step 5, Pre-personalization, of phase 2, the Pre-personalization Agent must prove his/her identity by means of an authentication mechanism based on Triple-DES with 112-bit keys. • In phase 3, Personalization, the Personalization Agent must prove his/her identity by means of an authentication mechanism based on Triple-DES with 112-bit keys. • In phase 4, Operational use, the user must prove his entitlement to access less sensitive data, i.e. DG1, DG2, and DG5 to DG16, by means of the PACE mechanism compliant to ICAO Doc 9303-11 [R30]. Access to sensitive data, i.e. DG3 and DG4, is allowed after the genuineness of the IC has been proven by means of the Chip Authentication mechanism defined in [R30], and after the user has proven his/her entitlement by means of the Terminal Authentication mechanism as defined in [R6]. After a successful authentication, the communication between the e-Document and the terminal is protected by the Secure Messaging mechanism defined in section 6 of the ISO 7816-4 specification [R36]. The integrity of the data stored under the LDS can be checked by means of the Passive Authentication mechanism defined in [R30]. The Active Authentication mechanism defined in [R30] may be used as an alternative technique to ascertain the genuineness of the chip. However, access to sensitive data requires the use of the Chip Authentication mechanism. Passive Authentication, PACE, Active Authentication, Chip Authentication, and EAC Antenna (non-TOE component) Substrate material (non-TOE component) Microcontroller module (TOE component) CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 29 of 177 mechanisms are described in more detail in the following subsections. 1.6.3.1 Passive Authentication Passive Authentication consists of the following steps (cf. [R30]): 1. The inspection system reads the Document Security Object (SOD), which contains the Document Signer Certificate (CDS, cf. [R29]), from the IC. 2. The inspection system builds and validates a certification path from a Trust Anchor to the Document Signer Certificate used to sign the Document Security Object (SOD) according to [R31]. 3. The inspection system uses the verified Document Signer Public Key (KPuDS) to verify the signature of the Document Security Object (SOD). 4. The inspection system reads relevant data groups from the IC. 5. The inspection system ensures that the contents of the data groups are authentic and unchanged by hashing the contents and comparing the result with the corresponding hash value in the Document Security Object (SOD). 1.6.3.2 Password Authenticated Connection Establishment PACE is a password-authenticated Diffie-Hellman key agreement protocol that provides secure communication and password-based authentication of the e-Document chip and the inspection system (i.e. the e-Document chip and the inspection system share the same password). PACE establishes secure messaging between an e-Document chip and an inspection system based on possibly weak (short) passwords. The security context is established in the Master File. The protocol enables the e-Document chip to verify that the inspection system is authorized to access stored data, and has the following features: • Strong session keys are provided independently of the strength of the password. • The entropy of the password used to authenticate the inspection system can be very low (e.g. 6 digits are sufficient in general). PACE supports, as part of the protocol execution, different mappings of the generator of the cryptographic group contained in the selected domain parameters into an ephemeral one. The following mappings are supported by the TOE: • Generic Mapping, based on a Diffie-Hellman key agreement; CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 30 of 177 • Integrated Mapping, based on a direct mapping of a nonce into an element of the cryptographic group; • Chip Authentication Mapping, which extends the Generic Mapping and integrates Chip Authentication into the PACE protocol. All the algorithm combinations (i.e. key agreement algorithms, mapping algorithms, block ciphers) and the standardized domain parameters specified in ICAO Doc 9303-11 [R30] are supported for PACE authentication. 1.6.3.3 Active Authentication Active Authentication authenticates the IC by signing a challenge sent by the inspection system with a private key known only to the IC (cf. [R30]). For this purpose, the IC contains its own Active Authentication key pair (KPrAA and KPuAA). A hash representation of Data Group 15 (public key info, KPuAA) is stored in the Document Security Object (SOD), and is therefore authenticated by the issuer’s digital signature. The corresponding private key (KPrAA) is stored in the IC secure memory. By authenticating the Document Security Object (SOD) and Data Group 15 by means of Passive Authentication (cf. section 1.6.3.1) in combination with Active Authentication, the inspection system verifies that the Document Security Object (SOD) has been read from a genuine IC. In accordance with ICAO Doc 9303 [R30], the ICAO application supports the following cryptographic specifications: • RSA, compliant with [R37], Digital Signature Scheme 1, with hash algorithms SHA- 256, SHA-384 and SHA-512 compliant with FIPS PUB 180-4 [R41] and keys of 2048 or 3072 bits. • ECDSA, plain signature format according to [R8]. Only prime curves with uncompressed points shall be used. A hash algorithm, whose output length is of the same length or shorter than the length of the ECDSA key in use, shall be used, with hash algorithm SHA-256, SHA-384 and SHA-512 compliant with FIPS PUB 180-4 [R41] and keys at least of 256 bits to a maximum of 512 bits. 1.6.3.4 Chip Authentication Chip Authentication is an ephemeral-static Diffie-Hellman key agreement protocol that provides secure communication and unilateral authentication of the e-Document chip (cf. [R30]). CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 31 of 177 The main differences with respect to Active Authentication are: • Challenge Semantics is prevented because the transcripts produced by this protocol are non-transferable. • Besides authentication of the e-Document chip, this protocol also provides strong session keys. Details on Challenge Semantics are described in [R30]. The static Chip Authentication key pair(s) must be stored on the e-Document chip. In more detail: • The private key is stored securely in the e-Document chip’s memory. • The public key is stored in Data Group 14. The protocol provides implicit authentication of both the e-Document chip itself and the stored data by performing secure messaging with the new session keys. In accordance with ICAO Doc 9303 [R30], the ICAO application supports Diffie-Hellman key agreement for Chip Authentication either on integer multiplicative groups (DH algorithm, cf. [R53]), with keys of 2048 bits, or on elliptic curve groups over prime fields (ECDH algorithm, cf. [R8]), with keys of 256, 320, 384, 512 and 521 bits. Chip Authentication may be performed either as a distinct protocol, or as part of the PACE protocol in case Chip Authentication Mapping is used. In the latter case, only ECDH may be used as key agreement algorithm. 1.6.3.5 Extended Access Control According to [R30], Extended Access Control is a security mechanism by means of which the e-Document chip authenticates the inspection systems authorized to read the optional biometric reference data and protects access to these data. Following BSI TR-03110 [R6] [R7], the ICAO application enforces Extended Access Control through the support of Terminal Authentication v1, which is a challenge-response protocol that provides explicit unilateral authentication of the terminal. This protocol enables the e-Document chip to verify that the terminal is entitled to access sensitive data. Terminal Authentication also authenticates the ephemeral public key chosen by the terminal to set up secure messaging through Chip Authentication (cf. section 1.6.3.4) or PACE with Chip Authentication Mapping (cf. section 1.6.3.2). In this way, the e-Document CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 32 of 177 chip binds the terminal’s access rights to the secure messaging session established by the authenticated ephemeral public key of the terminal. In more detail, the terminal sends to the e-Document chip a certificate chain that starts with a certificate verifiable with a trusted public key stored on the chip, and ends with the terminal certificate. Then, the terminal signs a plaintext containing its ephemeral public key with the private key associated to its certificate, and sends the resulting signature to the e-Document chip, which authenticates the terminal by verifying the certificates and the final signature. The read access rights to biometric data groups granted by the authentication are encoded in the certificates. Access to Data Group 3 alone, Data Group 4 alone, or both Data Group 3 and Data Group 4 may be granted. Following BSI TR-03110 [R6] [R7], the ICAO application supports Terminal Authentication with signature verification algorithms RSASSA-PKCS1-v1_5 and RSASSA-PSS (cf. [R51]) and ECDSA (cf. [R8]). Hash algorithms SHA-256 and SHA-512 (cf. [R41]) and keys of 2048 or 3072 bits are supported in the RSA case, while hash algorithm SHA-256, SHA-384 and SHA-512 (cf. [R41]) and key 256, 384, and 512 bits are supported in the ECC case.

Conformance claims 2.1 Common Criteria conformance claim This security target claims conformance to: • Common Criteria version 3.1 revision 5 [R9] [R10] [R11], as follows: o Part 2 (security functional requirements) extended, o Part 3 (security assurance requirements) conformant. The software part of the TOE runs on the chip NXP N7121. This integrated circuit is certified against Common Criteria at the assurance level EAL6+ (cf. Appendix A). 2.2 Package conformance claim This security target claims conformance to: • EAL5 assurance package augmented by ALC_DVS.2 and AVA_VAN.5, as defined in CC part 3 [R11]. 2.3 Protection Profile conformance claim This security target claims strict conformance to: • BSI-CC-PP-0056-V2-2012, Common Criteria Protection Profile, Machine Readable Travel Document with „ICAO Application”, Extended Access Control with PACE (EAC PP), version 1.3.2, December 2012 [R4], • BSI-CC-PP-0068-V2-2011-MA-01, Common Criteria Protection Profile, Machine Readable Travel Document using Standard Inspection Procedure with PACE (PACE PP), version 1.01, July 2014 [R5]. 2.4 Protection Profile conformance rationale This ST claims strict conformance to the PACE PP [R5] and EAC PP [R4]. The parts of the TOE listed in those Protection Profiles correspond to the ones listed in section 1.4.1 of this ST. This ST adopts as a reference the ICAO Doc 9303 Seventh Edition 2015. This new version includes the specification of the PACE protocol, and no longer uses the terms “Supplemental Access Control” and “SAC”. Due to this update, in this ST: CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 34 of 177 • any references to the ICAO Doc 9303 2006 specification in the EAC PP and in the PACE PP have been replaced with references to Doc 9303 2015, • any references to the ICAO “Supplemental Access Control” specification have been replaced with references to Doc 9303 2015, • the terms “Supplemental Access Control” and “SAC” in the PACE PP have been replaced with the terms “Password Authenticated Connection Establishment” and “PACE”. Being the TOE a general purpose electronic document, all references in the PPs to the use of the TOE as a travel document have been removed in this ST. For the same reason, with respect to the PPs, in this ST the acronym “MRTD” has been replaced by the term “e- Document”, the term "travel document" has been replaced by the terms "e-Document" or "electronic document", and the term "traveller" has been replaced by the terms "user" or "presenter". Such changed terms are printed in blue. With respect to the PPs, the role “MRTD Manufacturer” has been split into the roles Card Manufacturer and Pre-personalization Agent, acting in Phase 2 “Manufacturing” respectively in Step 4, Card Manufacturing and Step 5, Pre-personalization. Note that the Card Manufacturer is a role performing only the physical preparation of the TOE. In some parts of this ST the roles acting in Phase 2, i.e. the IC Manufacturer, the Card Manufacturer and the Pre-personalization Agent are collectively referred to as the Manufacturer. In this ST, the TOE will be delivered from the IC Manufacturer to the Card Manufacturer after Step 3 “IC Manufacturing” of Phase 2, as a chip, in accordance with Application Note 4 of the EAC PP [R4]. At TOE delivery, there is no user data or machine readable data available. The EF.DG14 and EF.DG15 files, containing part of the user data, are written by the Pre-personalization Agent in Step 5 “Pre-Personalization” of Phase 2. The remaining user data as well as applicative files are written by the Personalization Agent, during Phase 3 “Personalization”. The TOE provides a contact interface according to ISO/IEC 7816-2 [R35]; therefore, in addition to the contactless interface referred in the PPs, this ST makes also references to the contact interface. This ST adds some notes to warn that, according to [R54], the algorithm Triple-DES used for PACE and Chip Authentication, is classified as “legacy”. The security problem definition includes the assets, the subjects, the assumptions, the threats, and the organizational security policies of both PPs. Table 2-1 specifies the source (PACE PP or EAC PP) of assumptions, threats, and organizational security policies.

These extensions do not conflict with strict conformance to PACE PP. • An iteration label has been added to the EAC PP SFRs printed in underlined text, to distinguish them from the similar SFRs that have been added to this ST (see Table 2-5 below). The requirement definitions remain unchanged with respect to the PP. Iterations and changes to the SFRs, with respect to PACE PP and EAC PP, are listed in Table 2-5.

FCS_COP.1/AUTH Change Having FIPS 46-3 been withdrawn, NIST SP 800-67 and SP 800-38A have been referenced instead. See Application Note 43. FCS_CKM.1/DH_PACE Change in dependency rationale It has been found that some components fulfil dependency from FCS_COP.1. Therefore Justification 4 has been removed. FIA_API.1/AA Iteration This iteration has been added to cover the proof of identity by means of Active Authentication. FIA_API.1/CAV1 FIA_API.1/CAM Iteration An iteration labelled 'CAM' has been added to take into account PACE-CAM as an additional mechanism that the TOE must provide. The iteration label 'CAV1' has been added to better distinguish it from the other iteration. FIA_AFL.1/Pre-pers FIA_AFL.1/Pers Iteration Iterations have been added to distinguish between authentication failure handling throughout pre-operational TOE life cycle FCS_COP.1/AUTH Iteration This iteration has been added to cover the cryptographic mechanisms used in the authentication of the the Pre- personalization Agent and the Personalization Agent. FCS_COP.1/AA_SIGN/RSA Iteration This iteration has been added to cover the signature of Active Authentication data with RSA algorithm according to ICAO Doc 9303-11 [R30]. FCS_COP.1/AA_SIGN/ECDSA Iteration This iteration has been added to cover the signature of Active Authentication data with ECDSA algorithm according to ICAO Doc 9303-11 [R30].

FIA_UAU.4/PACE Change of Application Note The application note now clarifies that this SFR also relates to the authentication of the the Pre-personalization Agent (cf. Application Note 75). FIA_UAU.5.2/PACE Refinement The specification concerning Terminal Authentication takes into account the fact that session keys established during PACE-CAM may also be used. An alternative condition has been added for the TOE to accept authentication attempts by means of Terminal Authentication. FIA_UAU.6/EAC/CAV1 FIA_UAU.6/EAC/CAM Iteration An iteration labelled 'EAC/CAM' has been added to take into account PACE-CAM as an additional condition. The iteration label 'CAV1' has been added to the original SFR from the PP to distinguish it from the other iteration. FPT_EMS.1.2 Refinement A refinement has been added to better specify access to data through contact interface. FTP_ITC.1/CPS Iteration This iteration has been added to require data to be exchanged through a secure channel in Pre- personalization and in Personalization. FCS_CKM.1/CA FCS_COP.1/SIG_VER FIA_UAU.6/EAC Change in SFRs Rationale With respect to EAC PP [R4], the SFRs listed on the left are not mapped to the objective OT.AC_Pers since neither Chip Authentication nor Terminal Authentication are used for authentication of the Personalization Agent.

Security problem definition Application Note 7 With respect to the security problem definition contained in the PPs, this ST has some additions concerning Active Authentication. 3.1 Introduction 3.1.1 Assets Due to strict conformance to both EAC PP [R4] and PACE PP [R5], this ST includes, as assets to be protected, all assets listed in section 3.1 of those PPs. 3.1.1.1 Assets to be protected according to PACE PP The primary assets to be protected by the TOE as long as they are in scope of the TOE are listed in Table 3-1 (please refer to the glossary in section 10.2 for the term definitions). Table 3-1 Primary assets Object No. Asset Definition Generic security property to be maintained by the current security policy e-Document 1 User data stored on the TOE All data (being not authentication data) stored in the context of the ICAO application of the e-Document as defined in [R30] and being allowed to read out solely by an authenticated terminal acting as Basic Inspection System with PACE (in the sense of [R30]). This asset covers “User Data on the MRTD’s chip”, “Logical MRTD Data” and “sensitive User Data” in [R3]. Confidentiality4 Integrity Authenticity 4 Though not each data element stored on the TOE represents a secret, the specification [R30] anyway requires securing their confidentiality: only terminals authenticated according to [R30] can get access to the user data stored. They have to be operated according to P.Terminal. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 42 of 177 Object No. Asset Definition Generic security property to be maintained by the current security policy 2 User data transferred between the TOE and the terminal connected (i.e. an authority represented by Basic Inspection System with PACE) All data (being not authentication data) being transferred in the context of the ICAO application of the e-Document as defined in [R30] between the TOE and an authenticated terminal acting as Basic Inspection System with PACE (in the sense of [R30]). User data can be received and sent (exchange  {receive, send}). Confidentiality5 Integrity Authenticity 3 e-Document tracing data Technical information about the current and previous locations of the e-Document gathered unnoticeable by the e-Document holder recognising the TOE not knowing any PACE password. TOE tracing data can be provided/gathered. Unavailability6 Application Note 8 Please note that user data being referred to in the table above include, amongst other, individual-related (personal) data of the e-Document holder which also include his sensitive (i.e. biometric) data. Hence, the general security policy defined by the current PP also secures these specific e-Document holder’s data as stated in the table above. All these primary assets represent User Data in the sense of CC. The secondary assets also having to be protected by the TOE in order to achieve a sufficient protection of the primary assets are listed in Table 3-2. 5 Though not each data element being transferred represents a secret, the specification [R30] anyway requires securing their confidentiality: the secure messaging in encrypt-then-authenticate mode is required for all messages according to [R30]. 6 Represents a prerequisite for anonymity of the e-Document holder. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 43 of 177 Table 3-2 Secondary assets Object No. Asset Definition Property to be maintained by the current security policy e-Document 4 Accessibility to the TOE functions and data only for authorised subjects Property of the TOE to restrict access to TSF and TSF-data stored in the TOE to authorised subjects only. Availability 5 Genuineness of the TOE Property of the TOE to be authentic in order to provide claimed security functionality in a proper way. This asset also covers “Authenticity of the MRTD’s chip” in [R3]. Availability 6 TOE internal secret cryptographic keys Permanently or temporarily stored secret cryptographic material used by the TOE in order to enforce its security functionality. Confidentiality Integrity 7 TOE internal non- secret cryptographic material Permanently or temporarily stored non- secret cryptographic (public) keys and other non-secret material (Document Security Object SOD containing digital signature) used by the TOE in order to enforce its security functionality. Integrity Authenticity 8 e-Document communication establishment authorization data Restricted-revealable7 authorization information for a human user being used for verification of the authorization attempts as authorised user (PACE password). These data are stored in the TOE and are not to be sent to it. Confidentiality Integrity Application Note 9 Since the e-Document does not support any secret document holder authentication data and the latter may reveal, if necessary, his or her verification values of the PACE password to an authorised person or device, a successful PACE authentication of a terminal does not unambiguously mean that the e-Document holder is using TOE. 7 The e-Document holder may reveal, if necessary, his or her verification values of CAN and MRZ to an authorised person or device who definitely act according to respective regulations and are trustworthy. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 44 of 177 Application Note 10 e-Document communication establishment authorization data are represented by two different entities: (i) reference information being persistently stored in the TOE and (ii) verification information being provided as input for the TOE by a human user as an authorization attempt. The TOE shall secure the reference information as well as – together with the terminal connected8 - the verification information in the “TOE  terminal” channel, if it has to be transferred to the TOE. Please note that PACE passwords are not to be sent to the TOE. The secondary assets represent TSF and TSF-data in the sense of CC. 3.1.1.2 Assets to be protected according to EAC PP Logical e-Document sensitive User Data Sensitive biometric reference data (EF.DG3, EF.DG4) Application Note 11 Due to interoperability reasons, the ICAO Doc 9303-11 [R30] requires that Basic Inspection Systems may have access to logical e-Document data DG1, DG2, DG5 to DG16. The TOE is not in certified mode according to this ST, if it is accessed using BAC [R30] (conformance to the BAC certification [R17] [R18] is kept, though). Note that the BAC mechanism cannot resist attacks with high attack potential (cf. [R3]). If supported, it is therefore recommended to use PACE instead of BAC. If nevertheless BAC has to be used, it is recommended to perform either PACE-CAM or Chip Authentication v.1 before getting access to data (except DG14), as these mechanisms are resistant to potential attacks. A sensitive asset is the following more general one. Authenticity of the e-Document’s chip The authenticity of the e-Document’s chip personalised by the issuing State or Organization for the e-Document holder is used by the presenter to prove his possession of a genuine e- Document. 3.1.2 Subjects This security target considers the subjects defined in the PACE PP and in the EAC PP. 8 The e-Document holder may reveal, if necessary, his or her verification values of CAN and MRZ to an authorised person or device who definitely act according to respective regulations and are trustworthy. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 45 of 177 The subjects considered in accordance with the PACE PP are listed in Table 3-3. Table 3-3 Subjects and external entities according to PACE PP External Entity No. Subject No. Role Definition 1 1 e-Document holder A person for whom the e-Document Issuer has personalised the e-Document9 . This entity is commensurate with e-Document Holder in [R3]. Please note that an e-Document holder can also be an attacker (see below external entity No.9). 2 - e-Document presenter A person presenting the e-Document to a terminal10 and claiming the identity of the e-Document holder. This external entity is commensurate with “Traveller” in [R3]. Please note that an e-Document presenter can also be an attacker (see below external entity No.9). 3 2 Terminal A terminal is any technical system communicating with the TOE through the contact or contactless interfaces. The role “Terminal” is the default role for any terminal being recognised by the TOE as not being PACE authenticated (“Terminal” is used by the e- Document presenter). This entity is commensurate with “Terminal” in [R3]. 4 3 Basic Inspection System with PACE (BIS- PACE) A technical system being used by an inspection authority11 and verifying the e-Document presenter as the e-Document holder (for e-Document: by comparing the real biometric data (face) of the e- Document presenter with the stored biometric data (DG2) of the e-Document holder). BIS-PACE implements the terminal’s part of the PACE protocol and authenticates itself to the e- 9 That is, this person is uniquely associated with a concrete e-Document 10 In the sense of [R30] 11 Concretely, by a control officer CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 46 of 177 External Entity No. Subject No. Role Definition Document using a shared password (PACE password) and supports Passive Authentication. 5 - Document Signer (DS) An organization enforcing the policy of the CSCA and signing the Document Security Object stored on the e-Document for passive authentication. A Document Signer is authorised by the CSCA issuing the Document Signer Certificate (CDS), see [R31]. This role is usually delegated to a Personalization Agent. 6 - Country Signing Certification Authority (CSCA) An organization enforcing the policy of the e- Document Issuer with respect to confirming correctness of user and TSF data stored in the e- Document. The CSCA represents the country specific root of the PKI for the e-Document and creates the Document Signer Certificates within this PKI. The CSCA also issues the self-signed CSCA Certificate (CCSCA) having to be distributed by strictly secure diplomatic means, see [R31]. 7 4 Personalization Agent An organization acting on behalf of the e-Document Issuer to personalise the e-Document for its holder by some or all of the following activities (i) establishing the identity of the e-Document holder, (ii) enrolling the biometric reference data of the e- Document holder, (iii) writing a subset of these data on the physical e-Document (optical personalization) and storing them in the e-Document (electronic personalization) for the e-Document holder as defined in [R30], (iv) writing the document details data, (v) writing the initial TSF data, (vi) signing the Document Security Object defined in [R29] (in the role of DS). Please note that the role “Personalization Agent” may be distributed among several institutions according to the operational policy of the e- Document Issuer. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 47 of 177 External Entity No. Subject No. Role Definition This entity is commensurate with “Personalization Agent” in [R29]. 8 5 Manufacturer Generic term collectively identifying the IC Manufacturer, the Card Manufacturer and the Pre- personalization Agent. The Manufacturer is the default user of the TOE during the manufacturing life cycle phase. This entity is commensurate with “Manufacturer” in [R3]. 9 - Attacker A threat agent (a person or a process acting on his behalf) trying to undermine the security policy defined by the current PP, especially to change properties of the assets having to be maintained. The attacker is assumed to possess an at most high attack potential. Please note that the attacker might “capture” any subject role recognised by the TOE. This external entity is commensurate to “Attacker” in [R3]. Application Note 12 The subject “Basic Inspection System with BAC” (BIS-BAC) is described in another ST [R17] [R18]. In addition to the subjects defined by the PACE PP, this ST considers the following subjects defined by the EAC PP: • Country Verifying Certification Authority: The Country Verifying Certification Authority (CVCA) enforces the privacy policy of the issuing State or Organization with respect to the protection of sensitive biometric reference data stored in the e- Document. The CVCA represents the country specific root of the PKI of Inspection Systems and creates the Document Verifier Certificates within this PKI. The updates of the public key of the CVCA are distributed in the form of Country Verifying CA Link- Certificates. • Document Verifier: The Document Verifier (DV) enforces the privacy policy of the receiving State with respect to the protection of sensitive biometric reference data to be handled by the Extended Inspection Systems. The Document Verifier manages CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 48 of 177 the authorization of the Extended Inspection Systems for the sensitive data of the e- Document in the limits provided by the issuing States or Organizations in the form of the Document Verifier Certificates. • Terminal: A terminal is any technical system communicating with the TOE through the contact or contactless interfaces. • Inspection system (IS): A technical system used by the border control officer of the receiving State (i) in examining an e-Document presented by the user and verifying its authenticity and (ii) verifying the presenter as e-Document holder. The Extended Inspection System (EIS) performs the Advanced Inspection Procedure (see Figure 3-1) and therefore (i) contains a terminal for the contact or contactless communication with the e-Document’s chip, (ii) implements the terminals part of PACE and/or BAC, (iii) gets the authorization to read the logical e-Document either under PACE or BAC by optical reading the e-Document providing this information, (iv) implements the Terminal Authentication and Chip Authentication Protocols both Version 1 according to [R6], and (v) is authorized by the issuing State or Organization through the Document Verifier of the receiving State to read the sensitive biometric reference data. Security attributes of the EIS are defined by means of the Inspection System Certificates. BAC may only be used if supported by the TOE. If both PACE and BAC are supported by the TOE and the BIS, PACE must be used. • Attacker: In addition to the definition in Table 3-3, the definition of an attacker is refined as follows: A threat agent trying (i) to manipulate the logical e-Document without authorization, (ii) to read sensitive biometric reference data (i.e. EF.DG3, EF.DG4), (ii) to forge a genuine e-Document, or (iv) to trace an e-Document. Application Note 13 An impostor is attacking the inspection system as TOE IT environment independent on using a genuine, counterfeit or forged e-Document. Therefore, the impostor may use results of successful attacks against the TOE but the attack itself is not relevant for the TOE. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 49 of 177 Figure 3-1 Advanced Inspection Procedure The Chip Authentication step in Figure 3-1 may be skipped if a PACE-CAM authentication has been successfully performed. 3.2 Assumptions The assumptions describe the security aspects of the environment in which the TOE will be used or is intended to be used. 3.2.1 A.Passive_Auth PKI for Passive Authentication The issuing and receiving States or Organizations establish a public key infrastructure for passive authentication i.e. digital signature creation and verification for the logical e- ICAO application selection Basic Access Control (CONDITIONAL) Chip Authentication (CONDITIONAL) Passive Authentication with SOD Terminal Authentication PACE (CONDITIONAL) CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 50 of 177 Document. The issuing State or Organization runs a Certification Authority (CA) which securely generates, stores and uses the Country Signing CA Key pair. The CA keeps the Country Signing CA Private Key secret and is recommended to distribute the Country Signing CA Public Key to ICAO, all receiving States maintaining its integrity. The Document Signer: i. generates the Document Signer Key Pair, ii. hands over the Document Signer Public Key to the CA for certification, iii. keeps the Document Signer Private Key secret, and iv. uses securely the Document Signer Private Key for signing the Document Security Objects of the e-Documents. The CA creates the Document Signer Certificates for the Document Signer Public Keys and distributes them to the receiving States and Organizations. It is assumed that the Personalization Agent ensures that the Document Security Object contains only the hash values of the genuine user data according to [R29]. 3.2.2 A.Insp_Sys Inspection Systems for global interoperability The Extended Inspection System (EIS) for global interoperability (i) includes the Country Signing CA Public Key and (ii) implements the terminal part of PACE [R30] and/or BAC [R3]. BAC may only be used if supported by the TOE. If both PACE and BAC are supported by the TOE and the IS, PACE must be used. The EIS reads the logical e-Document under PACE or BAC and performs the Chip Authentication to verify the logical e-Document and establishes secure messaging. The Chip Authentication Protocol v.1 is skipped if PACE- CAM has previously been performed. EIS supports the Terminal Authentication Protocol v.1 in order to ensure access control and is authorized by the issuing State or Organization through the Document Verifier of the receiving State to read the sensitive biometric reference data. Justification: The assumption A.Insp_Sys does not confine the security objectives of [R5], as it repeats the requirements of P.Terminal and adds only assumptions for the Inspection Systems for handling the EAC functionality of the TOE. 3.2.3 A.Auth_PKI PKI for Inspection Systems The issuing and receiving States or Organizations establish a public key infrastructure for card verifiable certificates of the Extended Access Control. The Country Verifying CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 51 of 177 Certification Authorities, the Document Verifier and Extended Inspection Systems hold authentication key pairs and certificates for their public keys encoding the access control rights. The Country Verifying Certification Authorities of the issuing States or Organizations are signing the certificates of the Document Verifier and the Document Verifiers are signing the certificates of the Extended Inspection Systems of the receiving States or Organizations. The issuing States or Organizations distribute the public keys of their Country Verifying Certification Authority to their e-Document’s chip. Justification: This assumption only concerns the EAC part of the TOE. The issuing and use of card verifiable certificates of the Extended Access Control is neither relevant for the PACE part of the TOE, nor will the security objectives of [R5] be restricted by this assumption. For the EAC functionality of the TOE the assumption is necessary because it covers the pre-requisite for performing the Terminal Authentication Protocol Version 1. 3.3 Threats This section describes the threats to be averted by the TOE independently or in collaboration with its IT environment. These threats result from the TOE method of use in the operational environment and the assets stored in or protected by the TOE. The TOE in collaboration with its IT environment shall avert the threats as specified below. 3.3.1 T.Skimming Skimming e-Document/Capturing Card-Terminal Communication Adverse action: An attacker imitates an inspection system in order to get access to the user data stored on or transferred between the TOE and the inspecting authority connected via the contact or contactless interfaces of the TOE. Threat agent: having high attack potential, cannot read and does not know the correct value of the shared password (PACE password) in advance. Asset: confidentiality of logical e-Document data Application Note 14 A product using BIS-BAC cannot avert this threat in the context of the security policy defined in this ST. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 52 of 177 Application Note 15 The shared PACE password may be printed or displayed on the e- Document. Please note that if this is the case, the password does not effectively represent a secret, but nevertheless it is restricted-revealable, cf. OE.e-Document_Holder. 3.3.2 T.Eavesdropping Eavesdropping on the communication between the TOE and the PACE terminal Adverse action: An attacker is listening to the communication between the e-Document and the PACE authenticated BIS-PACE in order to gain the user data transferred between the TOE and the terminal connected. Threat agent: having high attack potential, cannot read and does not know the correct value of the shared password (PACE password) in advance. Asset: confidentiality of logical e-Document data Application Note 16 A product using BIS-BAC cannot avert this threat in the context of the security policy defined in this ST. 3.3.3 T.Tracing Tracing e-Document Adverse action: An attacker tries to gather TOE tracing data (i.e. to trace the movement of the e-Document) unambiguously identifying it directly by establishing a communication via the contact interface or remotely by establishing or listening to a communication via the contactless interface of the TOE. Threat agent: having high attack potential, cannot read and does not know the correct value of the shared password (PACE password) in advance. Asset: privacy of the e-Document holder Application Note 17 This threat completely covers and extends “T.Chip-ID” from BAC PP [R3]. Application Note 18 A product using BAC (whatever the type of the inspection system is: BIS-BAC) cannot avert this threat in the context of the security policy defined in this ST. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 53 of 177 3.3.4 T.Forgery Forgery of data Adverse action: An attacker fraudulently alters the User Data or/and TSF-data stored on the e-Document or/and exchanged between the TOE and the terminal connected in order to outsmart the PACE authenticated BIS- PACE by means of changed e-Document holder’s related reference data (like biographic or biometric data). The attacker does it in such a way that the terminal connected perceives these modified data as authentic one. Threat agent: having high attack potential Asset: integrity of the e-Document 3.3.5 T.Abuse-Func Abuse of Functionality Adverse action: An attacker may use functions of the TOE which shall not be used in TOE operational phase in order (i) to manipulate or to disclose the User Data stored in the TOE, (ii) to manipulate or to disclose the TSF-data stored in the TOE or (iii) to manipulate (bypass, deactivate or modify) soft-coded security functionality of the TOE. This threat addresses the misuse of the functions for the initialization and personalization in the operational phase after delivery to the e-Document holder. Threat agent: having high attack potential, being in possession of one or more e- Documents Asset: integrity and authenticity of the e-Document, availability of the functionality of the e-Document Application Note 19 Details of the relevant attack scenarios depend, for instance, on the capabilities of the test features provided by the IC Dedicated Test Software being not specified here. 3.3.6 T.Information_Leakage Information Leakage from e-Document CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 54 of 177 Adverse action: An attacker may exploit information leaking from the TOE during its usage in order to disclose confidential User Data or/and TSF-data stored on the e-Document or/and exchanged between the TOE and the terminal connected. The information leakage may be inherent in the normal operation or caused by the attacker. Threat agent: having high attack potential Asset: confidentiality User Data and TSF data of the e-Document Application Note 20 Leakage may occur through emanations, variations in power consumption, I/O characteristics, clock frequency, or by changes in processing time requirements. This leakage may be interpreted as a covert channel transmission, but is more closely related to measurement of operating parameters which may be derived either from measurements of the contactless interface (emanation) or direct measurements (by contact to the chip) and can then be related to the specific operation being performed. Examples are Differential Electromagnetic Analysis (DEMA) and Differential Power Analysis (DPA). Moreover, the attacker may try actively to enforce information leakage by fault injection (e.g. Differential Fault Analysis). 3.3.7 T.Phys-Tamper Physical Tampering Adverse action: An attacker may perform physical probing of the e-Document in order (i) to disclose the TSF-data, or (ii) to disclose/reconstruct the TOE’s Embedded Software. An attacker may physically modify the e- Document in order to alter (I) its security functionality (hardware and software part, as well), (ii) the User Data or the TSF-data stored on the e-Document. Threat agent: having high attack potential, being in possession of one or more legitimate e-Documents Asset: integrity and authenticity of the e-Document, availability of the functionality of the e-Document, confidentiality of User Data and TSF- data of the e-Document Application Note 21 Physical tampering may be focused directly on the disclosure or manipulation of the user data (e.g. the biometric reference data for the inspection system) or the TSF data (e.g. authentication key of the e-Document) or indirectly by preparation of the TOE to following attack methods by modification of security features (e.g. to enable CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 55 of 177 information leakage through power analysis). Physical tampering requires a direct interaction with the e-Document’s internals. Techniques commonly employed in IC failure analysis and IC reverse engineering efforts may be used. Before that, hardware security mechanisms and layout characteristics need to be identified. Determination of software design including treatment of the user data and the TSF data may also be a pre-requisite. The modification may result in the deactivation of a security function. Changes of circuitry or data can be permanent or temporary. 3.3.8 T.Malfunction Malfunction due to Environmental Stress Adverse action: An attacker may cause a malfunction the e-Document’s hardware and Embedded Software by applying environmental stress in order to (i) deactivate or modify security features or functionality of the TOE’ hardware or to (ii) circumvent, deactivate or modify security functions of the TOE’s Embedded Software. This may be achieved e.g. by operating the e-Document outside the normal operating conditions, exploiting errors in the e-Document’s Embedded Software or misusing administrative functions. To exploit these vulnerabilities an attacker needs information about the functional operation. Threat agent: having high attack potential, being in possession of one or more legitimate e-Documents, having information about the functional operation Asset: integrity and authenticity of the e-Document, availability of the functionality of the e-Document, confidentiality of User Data and TSF- data of the e-Document Application Note 22 A malfunction of the TOE may also be caused using a direct interaction with elements on the chip surface. This is considered as being a manipulation (refer to the threat T.Phys-Tamper) assuming a detailed knowledge about TOE’s internals. 3.3.9 T.Read_Sensitive_Data Read the sensitive biometric reference data Adverse action: An attacker tries to gain the sensitive biometric reference data through the communication interface of the e-Document’s chip. The attack T.Read_Sensitive_Data is similar to the threats T.Skimming (cf. [R17] [R18]) in respect of the attack path (communication interface) and the CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 56 of 177 motivation (to get data stored on the e-Document’s chip) but differs from those in the asset under the attack (sensitive biometric reference data vs. digital MRZ, digitized portrait and other data), the opportunity (i.e. knowing the PACE password) and therefore the possible attack methods. Note, that the sensitive biometric reference data are stored only on the e-Document’s chip as private sensitive personal data whereas the MRZ data and the portrait are visual readable on the physical e-Document as well. Threat agent: having high attack potential, knowing the PACE password, being in possession of a legitimate e-Document Asset: confidentiality of sensitive logical e-Document (i.e. biometric reference) data 3.3.10 T.Counterfeit Counterfeit of e-Document’s chip Adverse action: An attacker with high attack potential produces an unauthorized copy or reproduction of a genuine e-Document’s chip to be used as part of a counterfeit e-Document. This violates the authenticity of the e- Document’s chip used for authentication of a presenter by possession of a e-Document. The attacker may generate a new data set or extract completely or partially the data from a genuine e-Document’s chip and copy them on another appropriate chip to imitate this genuine e- Document’s chip. Threat agent: having high attack potential, being in possession of one or more legitimate e-Documents Asset: authenticity of logical e-Document data 3.4 Organizational Security Policies The TOE and/or its environment shall comply to the following Organizational Security Policies (OSP) as security rules, procedures, practices, or guidelines imposed by an organization upon its operations.

The e-Document Issuer guarantees correctness of the user data (amongst other of those, concerning the e-Document holder) and of the TSF-data permanently stored in the TOE. 3. The e-Document Issuer uses only such TOE’s technical components (IC) which enable traceability of the e-Documents in their manufacturing and issuing life cycle phases, i.e. before they are in the operational phase, cf. section 1.5 above. 4. If the e-Document Issuer authorizes a Pre-personalization Agent or a Personalization Agent to personalize the e-Document for e-Document holders, the e-Document Issuer has to ensure that the Pre-personalization Agent and the Personalization Agent act in accordance with the e-Document Issuer’s policy. 3.4.3 P.Card_PKI PKI for Passive Authentication (issuing branch) Application Note 23 The description below states the responsibilities of involved parties and represents the logical, but not the physical structure of the PKI. Physical distribution ways shall be implemented by the involved parties in such a way that all certificates belonging to the PKI are securely distributed / made available to their final destination, e.g. by using directory services.

The e-Document Issuer shall establish a public key infrastructure for the passive authentication, i.e. for digital signature creation and verification for the e-Document. For this aim, he runs a Country Signing Certification Authority (CSCA). The e- Document Issuer shall publish the CSCA Certificate (CCSCA). 2. The CSCA shall securely generate, store and use the CSCA key pair. The CSCA shall keep the CSCA Private Key secret and issue a self-signed CSCA Certificate (CCSCA) having to be made available to the e-Document Issuer by strictly secure means, see [R30]. The CSCA shall create the Document Signer Certificates for the Document Signer Public Keys (CDS) and make them available to the e-Document Issuer, see [R31]. 3. A Document Signer shall (i) generate the Document Signer Key Pair, (ii) hand over the Document Signer Public Key to the CSCA for certification, (iii) keep the Document Signer Private Key secret and (iv) securely use the Document Signer Private Key for signing the Document Security Objects of e-Documents. 3.4.4 P.Trustworthy_PKI Trustworthiness of PKI The CSCA shall ensure that it issues its certificates exclusively to the rightful organizations (DS) and DSs shall ensure that they sign exclusively correct Document Security Objects to be stored on the e-Document. 3.4.5 P.Terminal Abilities and trustworthiness of terminals The Basic Inspection Systems with PACE (BIS-PACE) shall operate their terminals as follows: 1. The related terminals (basic inspection system, cf. above) shall be used by terminal operators and by e-Document holders as defined in [R30] [R31]. 2. They shall implement the terminal parts of the PACE protocol [R30], of the Passive Authentication [R30] and use them in this order12. The PACE terminal shall use randomly and (almost) uniformly selected nonces, if required by the protocols (for generating ephemeral keys for Diffie-Hellmann). 12 This order is commensurate with [R30] CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 59 of 177 3. The related terminals need not to use any own credentials. 4. They shall also store the Country Signing Public Key and the Document Signer Public Key (in form of CCSCA and CDS) in order to enable and to perform Passive Authentication (determination of the authenticity of data groups stored in the e- Document [R29] [R30]). 5. The related terminals and their environment shall ensure confidentiality and integrity of respective data handled by them (e.g. confidentiality of PACE passwords, integrity of PKI certificates, etc.), where it is necessary for a secure operation of the TOE according to the current PP. 3.4.6 P.Sensitive_Data Privacy of sensitive biometric reference data The biometric reference data of finger(s) (EF.DG3) and iris image(s) (EF.DG4) are sensitive private personal data of the e-Document holder. The sensitive biometric reference data can be used only by inspection systems which are authorized for this access at the time the e- Document is presented to the inspection system (Extended Inspection Systems). The issuing State or Organization authorizes the Document Verifiers of the receiving States to manage the authorization of inspection systems within the limits defined by the Document Verifier Certificate. The e-Document’s chip shall protect the confidentiality and integrity of the sensitive private personal data even during transmission to the Extended Inspection System after Chip Authentication. 3.4.7 P.Personalization Personalization of the e-Document by issuing State or Organization only The issuing State or Organization guarantees the correctness of the biographical data, the printed portrait and the digitized portrait, the biometric reference data and other data of the logical e-Document with respect to the e-Document holder.

Security objectives This chapter describes the security objectives for the TOE and the security objectives for the TOE environment. The security objectives for the TOE environment are separated into security objectives for the development and production environment and security objectives for the operational environment. 4.1 Security objectives for the TOE This section describes the security objectives for the TOE addressing the aspects of identified threats to be countered by the TOE and organizational security policies to be met by the TOE. 4.1.1 OT.AC_Pre-pers Access Control for Pre-personalization of logical e-Document The TOE must ensure that the logical e-Document data in EF.DG14 and EF.DG15 under the LDS, as well as other TSF data (cfr. Error! Reference source not found.) can be written i n step 5, pre-personalization, by an authorized Pre-personalization Agent only. The logical e-Document pre-personalization data under the LDS, which includes at least the EF.DG14 and EF.DG15, may be written only during and cannot be changed after pre-personalization. 4.1.2 OT.Data_Integrity Integrity of Data The TOE must ensure integrity of the User Data and the TSF-data13 stored on it by protecting these data against unauthorised modification (physical manipulation and unauthorised modifying). The TOE must ensure integrity of the User Data and the TSF-data during their exchange between the TOE and the terminal connected (and represented by PACE authenticated BIS-PACE) after the PACE Authentication. 4.1.3 OT.Data_Authenticity Authenticity of Data 13 Where appropriate, see Table 3-2 above CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 61 of 177 The TOE must ensure authenticity of the User Data and the TSF-data14 stored on it by enabling verification of their authenticity at the terminal-side15. The TOE must ensure authenticity of the User Data and the TSF-data during their exchange between the TOE and the terminal connected (and represented by PACE authenticated BIS-PACE) after the PACE Authentication. It shall happen by enabling such a verification at the terminal-side (at receiving by the terminal) and by an active verification by the TOE itself (at receiving by the TOE)16. 4.1.4 OT.Data_Confidentiality Confidentiality of Data The TOE must ensure confidentiality of the User Data and the TSF-data17 by granting read access only to the PACE authenticated BIS-PACE connected. The TOE must ensure confidentiality of the User Data and the TSF-data during their exchange between the TOE and the terminal connected (and represented by PACE authenticated BIS-PACE) after the PACE Authentication. 4.1.5 OT.Tracing Tracing e-Document The TOE must prevent gathering TOE tracing data by means of unambiguous identifying the e-Document directly through establishing a communication via the contact interface, or remotely through establishing or listening to a communication via contactless interface of the TOE, without knowledge of the correct values of shared passwords (PACE passwords) in advance. 4.1.6 OT.Prot_Abuse-Func Protection against Abuse of Functionality The TOE must prevent that functions of the TOE, which may not be used in TOE operational phase, can be abused in order (i) to manipulate or to disclose the User Data stored in the TOE, (ii) to manipulate or to disclose the TSF-data stored in the TOE, (iii) to manipulate (bypass, deactivate or modify) soft-coded security functionality of the TOE. 14 Where appropriate, see Table 3-2 above 15 Verification of SOD 16 Secure messaging after PACE authentication, see also [R30] 17 Where appropriate, see Table 3-2 above CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 62 of 177 4.1.7 OT.Prot_Inf_Leak Protection against Information Leakage The TOE must provide protection against disclosure of confidential User Data and/or TSF- data stored and/or processed in the e-Document • by measurement and analysis of the shape and amplitude of signals or the time between events found by measuring signals on the electromagnetic field, power consumption, clock, or I/O lines, • by forcing a malfunction of the TOE, and/or • by a physical manipulation of the TOE. Application Note 24 This objective pertains to measurements with subsequent complex signal processing due to normal operation of the TOE or operations enforced by an attacker. 4.1.8 OT.Prot_Phys-Tamper Protection against Physical Tampering The TOE must provide protection of the confidentiality and integrity of the User Data, the TSF-data, and the e-Document’s Embedded Software by means of • measuring through galvanic contacts representing a direct physical probing on the chip’s surface except on pads being bonded (using standard tools for measuring voltage and current), or • measuring not using galvanic contacts but other types of physical interaction between charges (using tools used in solid-state physics research and IC failure analysis), • manipulation of the hardware and its security features, as well as • controlled manipulation of memory contents (User Data, TSF-data) with a prior • reverse-engineering to understand the design and its properties and functionality. 4.1.9 OT.Prot_Malfunction Protection against Malfunctions The TOE must ensure its correct operation. The TOE must prevent its operation outside the normal operating conditions where reliability and secure operation have not been proven or CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 63 of 177 tested. This is to prevent functional errors in the TOE. The environmental conditions may include external energy (esp. electromagnetic) fields, voltage (on any contacts), clock frequency or temperature. The following TOE security objectives address the aspects of identified threats to be countered involving TOE’s environment. 4.1.10 OT.Identification Identification of the TOE The TOE must provide means to store Initialization Data and Pre-Personalization Data in its non-volatile memory. The IC Identification Data must provide a unique identification of the IC during the manufacturing and the card issuing life cycle phases of the e-Document. The storage of the Initialization Data includes writing of the Pre-personalization key(s). The storage of the Pre-Personalization data includes writing of the Personalization key(s). 4.1.11 OT.AC_Pers Access Control for Personalization of logical e-Document The TOE must ensure that the logical e-Document data in EF.DG1 to EF.DG13 and EF.DG16, the Document security object according to LDS [R29] and the TSF data can be written by an authorized Personalization Agent only. The logical e-Document data in EF.DG1 to EF.DG13 and EF.DG16, and the TSF data (cfr. Error! Reference source not f ound.) may be written only during and cannot be changed after personalization of the document. Application Note 25 The OT.AC_Pers implies that the data of the LDS groups written during personalization for e-Document holder (at least EF.DG1 and EF.DG2) cannot be changed using write access after personalization. 4.1.12 OT.Sens_Data_Conf Confidentiality of sensitive biometric reference data The TOE must ensure the confidentiality of the sensitive biometric reference data (EF.DG3 and EF.DG4) by granting read access only to authorized Extended Inspection Systems. The authorization of the inspection system is drawn from the Inspection System Certificate used for the successful authentication and shall be a non-strict subset of the authorization defined in the Document Verifier Certificate in the certificate chain to the Country Verifier Certification CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 64 of 177 Authority of the issuing State or Organization. The TOE must ensure the confidentiality of the logical e-Document data during their transmission to the Extended Inspection System. The confidentiality of the sensitive biometric reference data shall be protected against attacks with high attack potential. 4.1.13 OT.Chip_Auth_Proof Proof of e-Document’s chip authenticity The TOE must support the Inspection Systems to verify the identity and authenticity of the e-Document’s chip as issued by the identified issuing State or Organization by means of either the PACE-CAM as defined in [R30] or the Chip Authentication Version 1 as defined in [R6]. The authenticity proof provided by e-Document’s chip shall be protected against attacks with high attack potential. Application Note 26 The OT.Chip_Auth_Proof implies the e-Document’s chip to have (i) a unique identity as given by the e-Document’s Document Number, (ii) a secret to prove its identity by knowledge i.e. a private authentication key as TSF data. The TOE shall protect this TSF data to prevent their misuse. The terminal shall have the reference data to verify the authentication attempt of e-Document’s chip i.e. a certificate for the Chip Authentication Public Key that matches the Chip Authentication Private Key of the e-Document’s chip. This certificate is provided by (i) the Chip Authentication Public Key (EF.DG14) in the LDS defined in [R29] and (ii) the hash value of DG14 in the Document Security Object signed by the Document Signer. The following Security Objective for the TOE is an addition to the objectives given by the Protection Profiles to cover the Active Authentication mechanism. 4.1.14 OT.Active_Auth_Proof Proof of e-Document’s chip authenticity The TOE must support the Basic Inspection Systems to verify the identity and authenticity of the e-Document’s chip as issued by the identified issuing State or Organization by means of the Active Authentication as defined in [R30]. The authenticity proof provided by e- Document’s chip shall be protected against attacks with high attack potential. 4.2 Security objectives for the operational environment e-Document Issuer as the general responsible CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 65 of 177 The e-Document Issuer as the general responsible for the global security policy related will implement the following security objectives for the TOE environment. 4.2.1 OE.Legislative_Compliance Issuing of the e-Document The e-Document Issuer must issue the e-Document and approve it using the terminals complying with all applicable laws and regulations. e-Document Issuer and CSCA: e-Document’s PKI (issuing) branch The e-Document Issuer and the related CSCA will implement the following security objectives for the TOE environment (see also the Application Note 23 above). 4.2.2 OE.Passive_Auth_Sign Authentication of e-Document by Signature The e-Document Issuer has to establish the necessary public key infrastructure as follows: the CSCA acting on behalf and according to the policy of the e-Document Issuer must (i) generate a cryptographically secure CSCA Key Pair, (ii) ensure the secrecy of the CSCA Private Key and sign Document Signer Certificates in a secure operational environment, and (iii) publish the Certificate of the CSCA Public Key (CCSCA). Hereby authenticity and integrity of these certificates are being maintained. A Document Signer acting in accordance with the CSCA policy must (i) generate a cryptographically secure Document Signing Key Pair, (ii) ensure the secrecy of the Document Signer Private Key, (iii) hand over the Document Signer Public Key to the CSCA for certification, (iv) sign Document Security Objects of genuine e-Documents in a secure operational environment only. The digital signature in the Document Security Object relates to all hash values for each data group in use according to [R29]. The Personalization Agent has to ensure that the Document Security Object contains only the hash values of genuine user data according to [R29]. The CSCA must issue its certificates exclusively to the rightful organizations (DS) and DSs must sign exclusively correct Document Security Objects to be stored on e-Document. 4.2.3 OE.Pre-personalization Pre-personalization of e-Document CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 66 of 177 The issuing State or Organization must ensure that the Pre-personalization Agent acting on behalf of the issuing State or Organization i. create DG14, DG15 and TSF data for the e-Document, ii. pre-personalize the e-Document together with the defined physical and logical security measures to protect the confidentiality and integrity of these data. 4.2.4 OE.Personalization Personalization of e-Document The e-Document Issuer must ensure that the Personalization Agent acting on his behalf (i) establish the correct identity of the e-Document holder and create the biographical data for the e-Document, (ii) enrol the biometric reference data of the e-Document holder, (iii) write a subset of these data on the physical Document (optical personalization) and store them in the e-Document (electronic personalization) for the e-Document holder as defined in [R29]18, (iv) write the document details data, (v) write the initial TSF data, (vi) sign the Document Security Object defined in [R30] (in the role of a DS). Terminal operator: Terminal’s receiving branch 4.2.5 OE.Terminal Terminal operating The terminal operators must operate their terminals as follows: 1. The related terminals (basic inspection systems, cf. above) are used by terminal operators and by e-Document holders as defined in [R30]. 2. The related terminals implement the terminal parts of the PACE protocol [R30], of the Passive Authentication [R30] (by verification of the signature of the Document Security Object) and use them in this order19. The PACE terminal uses randomly and (almost) uniformly selected nonces, if required by the protocols (for generating ephemeral keys for Diffie-Hellmann). 3. The related terminals need not to use any own credentials. 18 See also [R30]. 19 This order is commensurate with [R30] CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 67 of 177 4. The related terminals securely store the Country Signing Public Key and the Document Signer Public Key (in form of CCSCA and CDS) in order to enable and to perform Passive Authentication of the e-Document (determination of the authenticity of data groups stored in the e-Document, [R30]). 5. The related terminals and their environment must ensure confidentiality and integrity of respective data handled by them (e.g. confidentiality of the PACE passwords, integrity of PKI certificates, etc.), where it is necessary for a secure operation of the TOE according to the current ST. Application Note 27 OE.Terminal completely covers and extends “OE.Exam_MRTD”, “OE.Passive_Auth_Verif“ and “OE.Prot_Logical_MRTD” from BAC PP [R3]. e-Document holder Obligations 4.2.6 OE.e-Document_Holder e-Document holder Obligations The e-Document holder may reveal, if necessary, his or her verification values of the PACE password to an authorized person or device who definitely act according to respective regulations and are trustworthy. Issuing State or Organization The issuing State or Organization will implement the following security objectives of the TOE environment. 4.2.7 OE.Chip_Auth_Key_e-Document e-Document Authentication Key The issuing State or Organization has to establish the necessary public key infrastructure in order to (i) generate the e-Document’s Chip Authentication Key Pair, (ii) sign and store the Chip Authentication Public Key in the Chip Authentication Public Key data in EF.DG14 and (iii) support inspection systems of receiving States or Organizations to verify the authenticity of the e-Document’s chip used for genuine e-Document by certification of the Chip Authentication Public Key by means of the Document Security Object. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 68 of 177 Justification: This security objective for the operational environment is needed to counter the threat T.Counterfeit, as it specifies the pre-requisite for the Chip Authentication which is one of the features of the TOE described only in this Security Target. 4.2.8 OE.Authoriz_Sens_Data Authorization for Use of Sensitive Biometric Reference Data The issuing State or Organization has to establish the necessary public key infrastructure in order to limit the access to sensitive biometric reference data of e-Document holders to authorized receiving States or Organizations. The Country Verifying Certification Authority of the issuing State or Organization generates card verifiable Document Verifier Certificates for the authorized Document Verifier only. Justification: This security objective for the operational environment is needed in order to handle the Threat T.Read_Sensitive_Data, the Organizational Security Policy P.Sensitive_Data and the Assumption A.Auth_PKI as it specifies the pre-requisite for the Terminal Authentication Protocol v.1 as it concerns the need of an PKI for this protocol and the responsibilities of its root instance. The Terminal Authentication Protocol v.1 is one of the features of the TOE described only in this Security Target. The following Security Objective for the Operational Environment is an addition to the objectives given by the Protection Profiles to cover the Active Authentication mechanism. 4.2.9 OE.Active_Auth_Key_e-Document e-Document Active Authentication key The issuing State or Organization has to establish the necessary public key infrastructure in order to (i) generate the e-Document’s Active Authentication Key Pair, (ii) sign and store the Active Authentication Public Key in the Active Authentication Public Key data in EF.DG15 and (iii) support inspection systems of receiving States or Organizations to verify the authenticity of the e-Document’s chip used for genuine e-Document by certification of the Active Authentication Public Key by means of the Document Security Object. Receiving State or Organization The Receiving State or Organization will implement the following security objectives of the TOE environment. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 69 of 177 4.2.10 OE.Exam_e-Document Examination of the physical part of the e-Document The inspection system of the receiving State or Organization must examine the e-Document presented by the user to verify its authenticity by means of the physical security measures and to detect any manipulation of the physical part of the e-Document. The Basic Inspection System for global interoperability (i) includes the Country Signing CA Public Key and the Document Signer Public Key of each issuing State or Organization, and (ii) implements the terminal part of PACE [4] and/or the Basic Access Control [6]. Extended Inspection Systems perform additionally to these points the Chip Authentication as either part of PACE-CAM or as Chip Authentication Protocol Version 1 to verify the Authenticity of the presented e- Document’s chip. Justification: This security objective for the operational environment is needed in order to handle the Threat T.Counterfeit and the Assumption A.Insp_Sys by demanding the Inspection System to perform the Chip Authentication as either part of PACE-CAM or as Chip Authentication protocol v.1. OE.Exam_e-Document also repeats partly the requirements from above OE.Terminal and therefore also counters T.Forgery and A.Passive_Auth. This is done because this ST introduces the Extended Inspection System, which is needed to handle the features of a e-Document with Extended Access Control. 4.2.11 OE.Prot_Logical_e-Document Protection of data from the logical e-Document The inspection system of the receiving State or Organization ensures the confidentiality and integrity of the data read from the logical e-Document. The inspection system will prevent eavesdropping to their communication with the TOE before secure messaging is successfully established based on the Chip Authentication. Justification: This security objective for the operational environment is needed in order to handle the Assumption A.Insp_Sys by requiring the Inspection System to perform secure messaging based on the Chip Authentication. 4.2.12 OE.Ext_Insp_Systems Authorization of Extended Inspection Systems The Document Verifier of receiving States or Organizations authorizes Extended Inspection Systems by creation of Inspection System Certificates for access to sensitive biometric reference data of the logical e-Document. The Extended Inspection System authenticates CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 70 of 177 themselves to the e-Document’s chip for access to the sensitive biometric reference data with its private Terminal Authentication Key and its Inspection System Certificate. Justification: This security objective for the operational environment is needed in order to handle the Threat T.Read_Sensitive_Data, the Organizational Security Policy P.Sensitive_Data and the Assumption A.Auth_PKI as it specifies the pre-requisite for the Terminal Authentication Protocol v.1 as it concerns the responsibilities of the Document Verifier instance and the Inspection Systems. 4.3 Security objective rationale Table 4-1 provides an overview for security objectives coverage. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 71 of 177 Table 4-1 Security objective rationale OT.Sens_Data_Conf OT.Chip_Auth_Proof OT.Active_Auth_Proof OT.AC_Pre-pers OT.AC_Pers OT.Data_Integrity OT.Data_Authenticity OT.Data_Confidentiality OT.Tracing OT.Prot_Abuse-Func OT.Prot_Inf_Leak OT.Identification OT.Prot_Phys-Tamper OT.Prot_Malfunction OE.Chip_Auth_Key_e-Document OE.Active_Auth_Key_e-Document OE.Authoriz_Sens_Data OE.Exam_e-Document OE.Prot_Logical_e-Document OE.Ext_Insp_Systems OE.Pre-personalization OE.Personalization OE-Passive_Auth_Sign OE.Terminal OE.e-Document_Holder OE.Legislative_Compliance T.Read_Sensitive_Data X X X T.Counterfeit X X X X X T.Skimming X X X X T.Eavesdropping X T.Tracing X X T.Abuse-Func X T.Information_Leakage X T.Phys-Tamper X T.Malfunction X T.Forgery X X X X X X X X X X X P.Sensitive_Data X X X P.Personalization X X X P.Manufact X X X P.Pre-Operational X X X X X X P.Terminal X X P.Card_PKI X P.Trustworthy_PKI X A.Insp_Sys X X A.Auth_PKI X X A.Passive_Auth X X A detailed justification required for suitability of the security objectives to coup with the security problem definition is given below. The threat T.Skimming addresses accessing the User Data (stored on the TOE or transferred between the TOE and the terminal) using the TOE’s contact or contactless interfaces. This threat is countered by the security objectives OT.Data_Integrity, OT.Data_Authenticity, and OT.Data_Confidentiality through the PACE authentication. The objective OE.e-Document_Holder ensures that a PACE session can only be CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 72 of 177 established either by the e-Document holder itself or by an authorised person or device, and, hence, cannot be captured by an attacker. The threat T.Eavesdropping addresses listening to the communication between the TOE and a rightful terminal in order to gain the User Data transferred there. This threat is countered by the security objective OT.Data_Confidentiality through a trusted channel based on the PACE authentication. The threat T.Tracing addresses gathering TOE tracing data identifying it directly by establishing a communication via the contact interface or remotely by establishing or listening to a communication via the contactless interface of the TOE, whereby the attacker does not a priori know the correct values of the PACE password. This threat is directly countered by security objectives OT.Tracing (no gathering TOE tracing data) and OE.e- Document-Holder (the attacker does not a priori know the correct values of the shared passwords). The threat T.Forgery addresses the fraudulent, complete or partial alteration of the User Data or/and TSF-data stored on the TOE or/and exchanged between the TOE and the terminal. The security objective OT.AC_Pre-pers requires the TOE to limit the write access for the e-Document to the trustworthy Pre-personalization Agent (cf. OE.Pre- personalization). The security objective OT.AC_Pers requires the TOE to limit the write access for the e-Document to the trustworthy Personalization Agent (cf. OE.Personalization). The TOE will protect the integrity and authenticity of the stored and exchanged User Data or/and TSF-data as aimed by the security objectives OT.Data_Integrity and OT.Data_Authenticity, respectively. The objectives OT.Prot_Phys-Tamper and OT.Prot_Abuse-Func contribute to protecting integrity of the User Data or/and TSF-data stored on the TOE. A terminal operator operating his terminals according to OE.Terminal and performing the Passive Authentication using the Document Security Object as aimed by OE.Passive_Auth_Sign will be able to effectively verify integrity and authenticity of the data received from the TOE. Additionally, the examination of the presented e-Document book or card according to OE.Exam_e-Document “Examination of the physical part of the e-Document” shall ensure its authenticity by means of the physical security measures and detect any manipulation of the physical part of the e-Document. The threat T.Abuse-Func addresses attacks of misusing TOE’s functionality to manipulate or to disclosure the stored User- or TSF-data as well as to disable or to bypass the soft- coded security functionality. The security objective OT.Prot_Abuse-Func ensures that the usage of functions having not to be used in the operational phase is effectively prevented. The threats T.Information_Leakage, T.Phys-Tamper, and T.Malfunction are typical for integrated circuits like smart cards under direct attack with high attack potential. The protection of the TOE against these threats is obviously addressed by the directly related CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 73 of 177 security objectives OT.Prot_Inf_Leak, OT.Prot_Phys-Tamper, and OT.Prot_Malfunction, respectively. The threat T.Counterfeit “Counterfeit of e-Document chip data” addresses the attack of unauthorized copy or reproduction of the genuine e-Document's chip. This attack is thwarted by chip an identification and authenticity proof required by OT.Chip_Auth_Proof “Proof of e-Document’s chip authentication” using an authentication key pair to be generated by the issuing State or Organization. The Public Chip Authentication Key has to be written into EF.DG14 and signed by means of Documents Security Objects as demanded by OE.Chip_Auth_Key_e-Document “e-Document Authentication Key”. According to OE.Exam_e-Document “Examination of the physical part of the e-Document” the General Inspection system has to perform the Chip Authentication either part of PACE-CAM or as Chip Authentication Protocol Version 1 to verify the authenticity of the e-Document’s chip. In addition, the threat T.Counterfeit “Counterfeit of e-Document chip data” is countered by chip an identification and authenticity proof required by OT.Active_Auth_Proof “Proof of e- Document’s chip authentication” using an authentication key pair to be generated by the issuing State or Organization. The Public Active Authentication Key has to be written into EF.DG15 and signed by means of Documents Security Objects as demanded by OE.Active_Auth_Key_e-Document “e-Document Authentication Key”. The OSP P.Manufact “Manufacturing of the e-Document’s chip” requires a unique identification of the IC by means of the Initialization Data and the writing of the Pre- personalization Data and the Personalization data as being fulfilled by OT.Identification. OT.AC_Pre-pers and OE.Pre-personalization together enforce the OSP’s properties ‘correctness of the User- and the TSF-data stored’ and ‘authorization of e-Document Manufacturers’. Note: • The IC Manufacturer equips the TOE with the Pre-personalization key according to OT.Identification, Identification and Authentication of the TOE. • The Pre-personalization Agent equips the TOE with the Personalization key(s) according to OT.Identification, Identification and Authentication of the TOE. The security objective OT.AC_Pre-pers limits the management of TSF data and the management of TSF to the Pre-personalization Agent. The OSP P.Pre-Operational is enforced by the following security objectives: OT.Identification is affine to the OSP’s property ‘traceability before the operational phase’; OT.AC_Pre-pers, OT.AC_Pers, OE.Pre-personalization, and OE.Personalization together enforce the OSP’s properties ‘correctness of the User- and the TSF-data stored’ and ‘authorization of Pre-personalization Agent and Personalization Agent’; OE.Legislative_Compliance is affine to the OSP’s property ‘compliance with laws and regulations’. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 74 of 177 The OSP P.Terminal is obviously enforced by the objective OE.Terminal, whereby the one- to-one mapping between the related properties is applicable. Additionally, this OSP is countered by the security objective OE.Exam_e-Document, that enforces the terminals to perform the terminal part of the PACE protocol. The OSP P.Card_PKI is enforced by establishing the issuing PKI branch as aimed by the objective OE.Passive_Auth_Sign (for the Document Security Object). The OSP P.Trustworthy_PKI is enforced by OE.Passive_Auth_Sign (for CSCA, issuing PKI branch). The OSP P.Personalization “Personalization of the e-Document by issuing State or Organization only” addresses the (i) the enrolment of the logical e-Document by the Personalization Agent as described in the security objective for the TOE environment OE.Personalization “Personalization of logical e-Document”, and (ii) the access control for the user data and TSF data as described by the security objective OT.AC_Pers “Access Control for Personalization of logical e-Document”. Note: • The Pre-personalization Agent equips the TOE with the Personalization key(s) according to OT.Identification “Identification and Authentication of the TOE”. The security objective OT.AC_Pers limits the management of TSF data and the management of TSF to the Personalization Agent. The OSP P.Sensitive_Data “Privacy of sensitive biometric reference data” is fulfilled and the threat T.Read_Sensitive_Data “Read the sensitive biometric reference data” is countered by the TOE-objective OT.Sens_Data_Conf “Confidentiality of sensitive biometric reference data” requiring that read access to EF.DG3 and EF.DG4 (containing the sensitive biometric reference data) is only granted to authorized inspection systems. Furthermore, it is required that the transmission of these data ensures the data’s confidentiality. The authorization bases on Document Verifier certificates issued by the issuing State or Organization as required by OE.Authoriz_Sens_Data “Authorization for use of sensitive biometric reference data”. The Document Verifier of the receiving State has to authorize Extended Inspection Systems by creating appropriate Inspection System certificates for access to the sensitive biometric reference data as demanded by OE.Ext_Insp_Systems “Authorization of Extended Inspection Systems”. The OSP P.Terminal “Abilities and trustworthiness of terminals” is countered by the security objective OE.Exam_e-Document additionally to the security objectives from PACE PP [7]. OE.Exam_e-Document enforces the terminals to perform the terminal part of the PACE protocol. The examination of the e-Document addressed by the assumption A.Insp_Sys “Inspection Systems for global interoperability” is covered by the security objective for the TOE environment OE.Exam_e-Document “Examination of the physical part of the e-Document” CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 75 of 177 which requires the inspection system to examine physically the e-Document, the Basic Inspection System to implement the Basic Access Control, and the Extended Inspection Systems to implement and to perform the Chip Authentication Protocol Version 1 to verify the Authenticity of the presented e-Document’s chip. The security objective for the TOE environment OE.Prot_Logical_e-Document “Protection of data from the logical e- Document” requires the Inspection System to protect the logical e-Document data during the transmission and the internal handling. The assumption A.Passive_Auth “PKI for Passive Authentication” is directly covered by the security objective for the TOE environment OE.Passive_Auth_Sign “Authentication of e- Document by Signature” from PACE PP [R5] covering the necessary procedures for the Country Signing CA Key Pair and the Document Signer Key Pairs. The implementation of the signature verification procedures is covered by OE.Exam_e-Document “Examination of the physical part of the e-Document”. The assumption A.Auth_PKI “PKI for Inspection Systems” is covered by the security objective for the TOE environment OE.Authoriz_Sens_Data “Authorization for use of sensitive biometric reference data”, which requires the CVCA to limit the read access to sensitive biometrics by issuing Document Verifier certificates for authorized receiving States or Organizations only. The Document Verifier of the receiving State is required by OE.Ext_Insp_Systems “Authorization of Extended Inspection Systems” to authorize Extended Inspection Systems by creating Inspection System Certificates. Therefore, the receiving issuing State or Organization has to establish the necessary public key infrastructure.

Extended components definition This security target uses components defined as extensions to CC part 2 [R10]. These components are drawn from the PACE PP [R5] and the EAC PP [R4]. 5.1 Definition of family FAU_SAS To describe the security functional requirements of the TOE, the family FAU_SAS of the class FAU (Security audit) is defined here. This family describes the functional requirements for the storage of audit data. It has a more general approach than FAU_GEN, because it does not necessarily require the data to be generated by the TOE itself and because it does not give specific details of the content of the audit records. The family ‘Audit data storage (FAU_SAS)’ is specified as follows: Table 5-1 Family FAU_SAS FAU_SAS Audit data storage Family behaviour: This family defines functional requirements for the storage of audit data. Component levelling: FAU_SAS.1 Requires the TOE to provide the possibility to store audit data. Management There are no management activities foreseen. Audit There are no actions defined to be auditable. FAU_SAS.1 Audit storage Hierarchical to: No other components Dependencies: No dependencies. FAU_SAS.1.1 The TSF shall provide [assignment: authorized users] with the capability to store [assignment: list of audit information] in the audit records. 5.2 Definition of family FCS_RND To describe the IT security functional requirements of the TOE, the family FCS_RND of the class FCS (Cryptographic support) is defined here. This family describes the functional FAU_SAS Audit data storage 1 CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 77 of 177 requirements for random number generation used for cryptographic purposes. The component FCS_RND.1 is not limited to generation of cryptographic keys unlike the component FCS_CKM.1. The similar component FIA_SOS.2 is intended for non- cryptographic use. The family ‘Generation of random numbers (FCS_RND)’ is specified as follows: Table 5-2 Family FCS_RND FCS_RND Generation of random numbers Family behaviour: This family defines quality requirements for the generation of random numbers which are intended to be used for cryptographic purposes. Component levelling: FCS_RND.1 Generation of random numbers requires that random numbers meet a defined quality metric. Management: There are no management activities foreseen. Audit: There are no actions defined to be auditable. FCS_RND.1 Quality metric for random numbers Hierarchical to: No other components Dependencies: No dependencies. FCS_RND.1.1 The TSF shall provide a mechanism to generate random numbers that meet [assignment: a defined quality metric]. 5.3 Definition of family FIA_API To describe the security requirements of the TOE a sensitive family (FIA_API) of the Class FIA (Identification and authentication) is defined in the PP [R4]. This family describes the functional requirements for the proof of the claimed identity for the authentication verification by an external entity, where the other families of the class FIA address the verification of the identity of an external entity. Application Note 28 The other families of the Class FIA describe only the authentication verification of users’ identity performed by the TOE and do not describe the functionality of the user to prove their identity. The following paragraph defines the family FIA_API in the style of the CC part 2 (cf. [R11] “Explicitly stated IT security requirements (APE_SRE)”) from a TOE point of view. FCS_RND Generation of random numbers 1 CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 78 of 177 Table 5-3 Family FIA_API FIA_API Authentication Proof of Identity Family behaviour: This family defines functions provided by the TOE to prove their identity and to be verified by an external entity in the TOE IT environment. Component levelling: FIA_API.1 Authentication Proof of Identity. Management: The following actions could be considered for the management functions in FMT: Management of authentication information used to prove the claimed identity. Audit: There are no actions defined to be auditable. FIA_API.1 Authentication Proof of Identity Hierarchical to: No other components Dependencies: No dependencies. FIA_API.1.1 The TSF shall provide a [assignment: authentication mechanism] to prove the identity of the [assignment: authorized user or rule]. 5.4 Definition of family FMT_LIM The family FMT_LIM describes the functional requirements for the test features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE show that no other class is appropriate to address the specific issues of preventing abuse of functions by limiting the capabilities of the functions and by limiting their availability. The family “Limited capabilities and availability (FMT_LIM)” is specified as follows. Table 5-4 Family FMT_LIM FMT_LIM Limited capabilities and availability Family behaviour: This family defines requirements that limit the capabilities and availability of functions in a combined manner. Note that FDP_ACF restricts the access to functions whereas the Limited capability of this family requires the functions themselves to be designed in a specific manner. FIA_API Authentication Proof of Identity 1 CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 79 of 177 FMT_LIM.1 Limited capabilities Hierarchical to: No other components Dependencies: FMT_LIM.2 Limited availability. FMT_LIM.1.1 The TSF shall be designed in a manner that limits their capabilities so that in conjunction with “Limited availability (FMT_LIM.2)” the following policy is enforced [assignment: Limited capability and availability policy]. FMT_LIM.2 Limited availability Hierarchical to: No other components Dependencies: FMT_LIM.1 Limited capabilities. FMT_LIM.2.1 The TSF shall be designed in a manner that limits their availability so that in conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced [assignment: Limited capability and availability policy]. Application Note 29 The functional requirements FMT_LIM.1 and FMT_LIM.2 assume that there are two types of mechanisms (limited capabilities and limited availability) which together shall provide protection in order to enforce the policy. This also allows that • the TSF is provided without restrictions in the product in its user environment but its capabilities are so limited that the policy is enforced, or conversely • the TSF is designed with test and support functionality that is removed from, or disabled in, the product prior to the Operational Use Phase. Component levelling: FMT_LIM.1 Limited capabilities requires that the TSF is built to provide only the capabilities (perform action, gather information) necessary for its genuine purpose. Management: There are no management activities foreseen. Audit: There are no actions defined to be auditable. FMT_LIM.2 Limited availability requires that the TSF restrict the use of functions (refer to Limited capabilities (FMT_LIM.1)). This can be achieved, for instance, by removing or by disabling functions in a specific phase of the TOE’s life-cycle. Management: There are no management activities foreseen. Audit: There are no actions defined to be auditable. FMT_LIM Limited capabilities and availability 1 2 CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 80 of 177 The combination of both requirements shall enforce the related policy. 5.5 Definition of family FPT_EMS The family FPT_EMS (TOE Emanation) of the class FPT (Protection of the TSF) is defined here to describe the IT security functional requirements of the TOE. The TOE shall prevent attacks against secret data stored in and used by the TOE where the attack is based on external observable physical phenomena of the TOE. Examples of such attacks are evaluation of TOE’s electromagnetic radiation, simple power analysis (SPA), differential power analysis (DPA), timing attacks, etc. This family describes the functional requirements for the limitation of intelligible emanations being not directly addressed by any other component of CC part 2 [R5]. The family ‘TOE Emanation (FPT_EMS)’ is specified as follows: Table 5-5 Family FPT_EMS FPT_EMS Family behaviour: This family defines requirements to mitigate intelligible emanations. Component levelling: FPT_EMS.1 TOE emanation has two constituents: • FPT_EMS.1.1 Limit of Emissions requires to not emit intelligible emissions enabling access to TSF data or user data. • FPT_EMS.1.2 Interface Emanation requires to not emit interface emanation enabling access to TSF data or user data. Management: There are no management activities foreseen. Audit: There are no actions defined to be auditable. FPT_EMS.1 TOE Emanation Hierarchical to: No other components Dependencies: No dependencies. FPT_EMS.1.1 The TOE shall not emit [assignment: types of emissions] in excess of [assignment: specified limits] enabling access to [assignment: list of types of TSF data] and [assignment: list of types of user data]. FPT_EMS.1.2 The TSF shall ensure [assignment: type of users] are unable to use the following interface [assignment: type of connection] to gain FPT_EMS TOE emanation 1 CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 81 of 177 access to [assignment: list of types of TSF data] and [assignment: list of types of user data].

Security functional requirements The CC allows several operations to be performed on functional requirements: refinement, selection, assignment, and iteration are defined in paragraph C.4 of Part 1 [R9] of the CC. Each of these operations is used in this PP. The refinement operation is used to add detail to a requirement, and thus further restricts a requirement. Refinement of security requirements is denoted by the word “Refinement” in bold text and the added/changed words are in bold text. In cases where words from a CC requirement were deleted, a separate attachment indicates the words that were removed. The selection operation is used to select one or more options provided by the CC in stating a requirement. Selections that have been made by the PP authors are denoted as underlined text. Selections made by the ST author are denoted as underlined bold text and the original text of the component is given by a footnote. The assignment operation is used to assign a specific value to an unspecified parameter, such as the length of a password. Assignments that have been made by the PP authors are denoted as underlined text. Assignments made by the ST author are denoted as underlined bold text and the original text of the component is given by a footnote. In some cases, the assignment made by the PP authors defines a selection performed by the ST author. Thus, this text is underlined and italicized like this. The iteration operation is used when a component is repeated with varying operations. Iteration is denoted by showing a slash “/”, and the iteration indicator after the component identifier. The definition of the subjects “Manufacturer”, “Personalization Agent”, “Extended Inspection System”, “Country Verifying Certification Authority”, “Document Verifier” and “Terminal” used in the following chapter is given in section 3.1.2. Note that all these subjects are acting for homonymous external entities. All used objects are defined either in section 10.2 or in the following table. The operations “write”, “modify”, “read” and “disable read access” are used in accordance with the general linguistic usage. The operations “store”, “create”, “transmit”, “receive”, “establish communication channel”, “authenticate” and “re- authenticate” are originally taken from [R10]. The operation “load” is synonymous to “import” used in [R10]. Table 6-1 provides the definition of security attributes.

The CSCA also issues the self-signed CSCA Certificate (CCSCA) to be distributed by strictly secure diplomatic means, see [R31]. Document Signer Key Pairs and Certificates The Document Signer Certificate CDS is issued by the Country Signing Certification Authority. It contains the Document Signer Public Key (PKDS) as authentication reference data. The Document Signer acting under the policy of the CSCA signs the Document Security Object (SOD) of the e-Document with the Document Signer Private Key (SKDS), and the signature will be verified by a terminal as the Passive Authentication with the Document Signer Public Key (PKDS).

Ephemeral keys (from PACE PP [R5]) PACE authentication ephemeral key pair (ephem-SKPICC-PACE, ephem-PKPICC-PACE) The ephemeral PACE Authentication Key Pair (ephem-SKPICC- PACE, ephem-PKPICC-PACE) is used for Key Agreement Protocol: Diffie-Hellman (DH) according to PKCS #3 or Elliptic Curve Diffie-Hellman (ECDH; ECKA key agreement algorithm) according to BSI TR-03111 [R8], cf. [R30]. Receiving PKI branch (from EAC PP [R4]) Country Verifying Certification Authority Private Key (SKCVCA) The Country Verifying Certification Authority (CVCA) holds a private key (SKCVCA) used for signing the Document Verifier Certificates. Country Verifying Certification Authority Public Key (PKCVCA) The TOE stores the Country Verifying Certification Authority Public Key (PKCVCA) as part of the TSF data to verify the Document Verifier Certificates. The PKCVCA has the security attribute Current Date as the most recent valid effective date of the Country Verifying Certification Authority Certificate or of a domestic Document Verifier Certificate. Country Verifying Certification Authority Certificate (CCVCA) The Country Verifying Certification Authority Certificate may be a self-signed certificate or a link certificate (cf.

After successful authentication of the chip the terminal may identify itself as (i) Extended Inspection System by selection of the templates for the Terminal Authentication Protocol Version 1 or (ii) if necessary and available by authentication as Personalization Agent (using the Personalization key). Application Note 69 In Step 5, Pre-personalization, of Phase 2, Manufacturing of the TOE, the Pre-personalization Agent is the only user role known to the TOE which writes the Pre-personalization Data in the audit records of the IC. The Pre-personalization Agent creates the user role Personalization Agent for transition from Phase 2 to Phase 3, Personalization of the e-Document. The users in roles Pre-personalization Agent or Personalization Agent identify themselves by means of selecting the authentication key. After personalization in Phase 3, the PACE domain parameters, the Chip Authentication data, and Terminal Authentication Reference Data are written into the TOE. The Inspection System is identified as default user after power up or reset of the TOE i.e. the TOE will run the PACE protocol, to gain access to the Chip Authentication Reference Data and to run the Chip Authentication Protocol Version 1. After successful authentication of the chip the terminal may identify itself as (i) Extended Inspection System by selection of the templates for the Terminal Authentication Protocol Version 1, or (ii) if necessary and available by authentication as Personalization Agent (using the Personalization key).

Hence, they define authentication procedure(s) for the Pre-personalization Agent and the Personalization Agent. The TOE must functionally support these authentication procedures being subject to evaluation within the assurance components ALC_DEL.1 and AGD_PRE.1. The TOE assumes the user roles Pre-personalization Agent or Personalization Agent, when a terminal proves the respective Terminal Authorization Level as defined by the related policy (policies).

Dependencies: FMT_LIM.2 Limited availability FMT_LIM.1.1: The TSF shall be designed in a manner that limits their capabilities so that in conjunction with “Limited availability (FMT_LIM.2)” the following policy is enforced: Deploying Test Features after TOE Delivery does not allow: 1. User Data to be disclosed or manipulated, 2. TSF data to be disclosed or manipulated, 3. software to be reconstructed, 4. substantial information about construction of TSF to be gathered which may enable other attacks, and 5. sensitive User Data (EF.DG3 and EF.DG4) to be disclosed130.

Dependencies: FMT_LIM.1 Limited capabilities FMT_LIM.2.1: The TSF shall be designed in a manner that limits their availability so that in conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced: Deploying Test Features after TOE Delivery does not allow: 1. User Data to be disclosed or manipulated, 2. TSF data to be disclosed or manipulated, 3. software to be reconstructed, 4. substantial information about construction of TSF to be gathered which may enable other attacks, and 5. sensitive User Data (EF.DG3 and EF.DG4) to be disclosed131. Application Note 99 The formulation of “Deploying Test Features …” in FMT_LIM.2.1 might be a little bit misleading since the addressed features are no longer available (e.g. by disabling or removing the respective functionality). Nevertheless, the combination of FMT_LIM.1 and FMT_LIM.2 is introduced to provide an optional approach to enforce the same policy. Note that the term “software” in item 4 of FMT_LIM.1.1 and FMT_LIM.2.1 refers to both IC Dedicated and IC Embedded Software. Application Note 100 The following SFRs are iterations of the component “Management of TSF data” (FMT_MTD.1). The TSF data include, but are not limited to, those identified below. The TOE shall meet the requirement “Management of TSF data (FMT_MTD.1)” as specified below (Common Criteria Part 2).

The Inspection System Public Key contained in the Inspection System Certificate in a valid certificate chain is a secure value for the authentication reference data of the Extended Inspection System. The intersection of the Certificate Holder Authorizations contained in the certificates of a valid certificate chain is a secure value for Terminal Authorization of a successful authenticated Extended Inspection System. Application Note 109 The Terminal Authentication is used for Extended Inspection System as required by FIA_UAU.4/PACE and FIA_UAU.5/PACE. The Terminal Authorization is used as TSF data for access control required by FDP_ACF.1/TRM. 6.7 Class FPT: Protection of the security functions The TOE shall prevent inherent and forced illicit information leakage for User Data and TSF- data. The security functional requirement FPT_EMS.1 addresses the inherent leakage. With respect to the forced leakage they have to be considered in combination with the security functional requirements “Failure with preservation of secure state (FPT_FLS.1)” and “TSF testing (FPT_TST.1)” on the one hand and “Resistance to physical attack (FPT_PHP.3)” on the other. The SFRs “Limited capabilities (FMT_LIM.1)”, “Limited availability (FMT_LIM.2)” and “Resistance to physical attack (FPT_PHP.3)” together with the SAR “Security architecture description” (ADV_ARC.1) prevent bypassing, deactivation and manipulation of the security features or misuse of TOE security functionality. The TOE shall meet the requirement “TOE emanation (FPT_EMS.1)” as specified below (Common Criteria Part 2 extended). 6.7.1 FPT_EMS.1 TOE Emanation Hierarchical to: No other components.

Application Note 110 The SFR FPT_EMS.1.1 in this ST covers the definition in the EAC PP [R4] that, in turn, extends the definition in PACE PP [R5] by EAC aspects 1., 5. and 6. The SFR FPT_EMS.1.2 in this ST covers the definition in the EAC PP [R4] that, in turn, extends the definition in PACE PP [7] by EAC aspects 4) and 5). These extensions do not conflict with the strict conformance to PACE PP. Application Note 111 The TOE shall prevent attacks against the listed secret data where the attack is based on external observable physical phenomena of the TOE. Such attacks may be observable at the interfaces of the TOE or may be originated from internal operation of the TOE or may be caused by an attacker that varies the physical environment under which the TOE operates. The set of measurable physical phenomena is influenced by the technology employed to implement the smart card. The e-Document’s chip can provide a smart card contactless interface according to ISO/IEC 14443 [R38] [R39] and contact based interface according to ISO/IEC 7816-2 [R35] as well (in case the package only provides a contactless interface the attacker might gain access to the contacts anyway). Examples of measurable phenomena include, but are not limited to variations in the power consumption, the timing of signals and the electromagnetic radiation due to internal operations or data transmissions. The following security functional requirements address the protection against forced illicit information leakage including physical manipulation.

Application Note 112 A dedicated software in the protected ROM of the IC N7121 provides full test capabilities, not accessible by the Security IC Embedded Software after delivery. Application Note 113 At start-up, the OS checks whether a reset has been triggered by a sensor. If this is the case, a reset counter is incremented. If the count exceeds 32, then the chip is irreversibly blocked. Before any read of the TSF data, the EEPROM memory is checked for possible fault injection events. If this is the case, the reset counter is incremented and the chip goes into an endless loop. During normal operation, tests of the random number generation and integrity checks are also executed. Application Note 114 FPT_TST.1.3 protects the integrity of the code by physical means, using the mechanisms of the underlying IC. After delivery, the TOE does not use logical means to check the integrity of the code, as it relies on the IC security features to provide verification of the code integrity. The TOE shall meet the requirement “Resistance to physical attack (FPT_PHP.3)” as specified below (Common Criteria Part 2). 6.7.4 FPT_PHP.3 Resistance to physical attack Hierarchical to: No other components. Dependencies: No dependencies. FPT_PHP.3.1: The TSF shall resist physical manipulation and physical probing178 to the TSF179 by responding automatically such that the SFRs are always enforced. 177 [selection: [assignment: parts of TSF], TSF] 178 [assignment: physical tampering scenarios] 179 [assignment: list of TSF devices/elements] CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 134 of 177 Application Note 115 The TOE will implement appropriate measures to continuously counter physical manipulation and physical probing. Due to the nature of these attacks (especially manipulation) the TOE can by no means detect attacks on all of its elements. Therefore, permanent protection against these attacks is required ensuring that the TSP could not be violated at any time. Hence, ‘automatic response’ means here (i) assuming that there might be an attack at any time and (ii) countermeasures are provided at any time.

This will be ensured by TSF according to SFR FAU_SAS.1. The SFR FMT_MTD.1/INI_ENA allows only the Manufacturer to write Initialization and Pre-personalization Data (including the Personalization key). The SFR FMT_MTD.1/INI_DIS requires the Personalization Agent to disable access to Initialization and Pre-personalization Data in the life cycle phase ‘operational use’. The SFRs FMT_SMF.1 and FMT_SMR.1/PACE support the functions and roles related. The security objective OT.AC_Pre-pers “Access Control for Pre-personalization of logical e-Document” addresses the access control of the writing the logical e-Document in Step 5 CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 139 of 177 “Pre-personalization”. The Pre-personalization Agent is authenticated by using the CPS mechanism based on Triple-DES (FCS_CKM.1/CPS, FCS_COP.1/AUTH, and FCS_RND.1 for key generation) with the Pre-personalization keys. The authentication of the terminal as Pre-personalization Agent shall be performed by TSF according to SFRs FIA_UAU.4/PACE and FIA_UAU.5/PACE. If the Pre-personalization Terminal wants to authenticate itself to the TOE by means of the Authentication Mechanism with Pre-personalization key, the TOE will use the TSF according to FCS_RND.1 (for the generation of the challenge), FCS_COP.1/CA_ENC (to verify the authentication attempt and for secure messaging), and FCS_COP.1/CA_MAC (for the ENC_MAC_Mode secure messaging). The session keys are destroyed according to FCS_CKM.4 after use. The justification for the SFRs FAU_SAS.1 and FMT_MTD.1/INI_ENA arises from the justification for OT.Identification above with respect to the Pre-personalization Data. The write access to the logical e-Document data is defined by the SFRs FIA_UID.1/PACE, FIA_UAU.1/PACE, FDP_ACC.1/TRM, and FDP_ACF.1/TRM in the same way: only the successfully authenticated Pre-personalization Agent is allowed to write the data of the groups EF.DG14, EF.DG15 of the logical e-Document. The SFR FMT_SMR.1/PACE lists the roles (including Pre-personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions (including Pre-personalization). The SFRs FMT_MTD.1/KEY_READ and FPT_EMS.1 restrict the access to the Personalization keys, the Chip Authentication Private Key, the PACE passwords, and the Active Authentication key. The security objective OT.AC_Pers “Access Control for Personalization of logical e- Document” addresses the access control of the writing the logical e-Document. The Personalization Agent is authenticated by using the CPS mechanism based on Triple-DES (FCS_CKM.1/CPS, FCS_COP.1/AUTH, and FCS_RND.1 for key generation), with the Personalization keys. The authentication of the terminal as Personalization Agent shall be performed by TSF according to SFRs FIA_UAU.4/PACE and FIA_UAU.5/PACE. If the Personalization Terminal wants to authenticate itself to the TOE by means of the Authentication Mechanism with the Personalization key, the TOE will use the TSF according to FCS_RND.1 (for the generation of the challenge), FCS_COP.1/CA_ENC (to verify the authentication attempt and for secure messaging), and FCS_COP.1/CA_MAC (for the ENC_MAC_Mode secure messaging). The session keys are destroyed according to FCS_CKM.4 after use. The justification for the SFRs FAU_SAS.1, FMT_MTD/INI_ENA, and FMT_MTD.1/INI_DIS arises from the justification for OT.Identification above with respect to the Personalization Data. The write access to the logical e-Document data is defined by the SFRs FIA_UID.1/PACE, FIA_UAU.1/PACE, FDP_ACC.1/TRM, and FDP_ACF.1/TRM in the same way: only the successfully authenticated Personalization Agent is allowed to write the data of the groups EF.DG1 to EF.DG13, EF.DG16 of the logical e-Document. FMT_MTD.1/PA covers the related property of OT.AC_Pers (writing SOD and, in generally, personalization data). The SFR FMT_SMR.1/PACE lists the roles (including Personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization). The SFRs FMT_MTD.1/KEY_READ and FPT_EMS.1 restrict the access CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 140 of 177 to the Personalization keys, the Chip Authentication Private Key, the PACE passwords, and the Active Authentication key. Application Note 117 The Personalization Agent can authenticate itself using the symmetric authentication mechanism only. No other authentication mechanism is available to the Personalization Agent. The security objective OT.Data_Integrity “Integrity of personal data” requires the TOE to protect the integrity of the logical e-Document stored on the e-Document’s chip against physical manipulation and unauthorized writing. Physical manipulation is addressed by FPT_PHP.3. Logical manipulation of stored user data is addressed by FDP_ACC.1/TRM and FDP_ACF.1/TRM: only the Pre-personalization Agent or the Personalization Agent are allowed to write the data in EF.DG1 to EF.DG16 of the logical e-Document of the logical e- Document (FDP_ACF.1.2/TRM, rule 1), and terminals are not allowed to modify any of the data in EF.DG1 to EF.DG16 of the logical e-Document (cf. FDP_ACF.1.4/TRM). FMT_MTD.1/PA requires that SOD containing signature over the User Data stored on the TOE and used for the Passive Authentication is allowed to be written by the Personalization Agent only and, hence, is to be considered as trustworthy. The Personalization Agent must identify and authenticate themselves according to FIA_UID.1/PACE and FIA_UAU.1/PACE before accessing these data. The Pre-personalization Agent must identify and authenticate themselves according to FIA_UID.1/PACE and FIA_UAU.1/PACE before accessing data in Step 5 “Pre-personalization”. FIA_UAU.4/PACE, FIA_UAU.5/PACE, and FCS_CKM.4 represent some required specific properties of the protocols used. The SFR FMT_SMR.1/PACE lists the roles and the SFR FMT_SMF.1 lists the TSF management functions. Unauthorised modifying of the exchanged data is addressed, in the first line, in Pre- personalization and Personalization by FTP_ITC.1/CPS, and in the Operational Use phase by FDP_UCT.1/TRM, FDP_UIT.1/TRM and FTP_ITC.1/PACE using FCS_COP.1/PACE_MAC for PACE. For secured data exchange in Pre-personalization and in Personalization, a prerequisite for establishing this trusted channel is a successful CPS Authentication using FCS_CKM.1/CPS. For PACE secured data exchange, a prerequisite for establishing this trusted channel is a successful PACE Authentication (FIA_UID.1/PACE, FIA_UAU.1/PACE) using FCS_CKM.1/DH_PACE and possessing the special properties FIA_UAU.5/PACE, FIA_UAU.6/PACE resp. FIA_UAU.6/EAC/CAV1, FIA_UAU.6/EAC/CAM. The trusted channel is established using PACE, Chip Authentication v.1, and Terminal Authentication v.1. FDP_RIP.1 requires erasing the values of session keys (here for KMAC). The TOE supports the inspection system detect any modification of the transmitted logical e-Document data after Chip Authentication v.1. The SFRs FIA_UAU.6/EAC/CAV1, FIA_UAU.6/EAC/CAM, and FDP_UIT.1/TRM require the integrity protection of the transmitted data after Chip Authentication performed either as part of PACE-CAM or as Chip CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 141 of 177 Authentication Protocol v.1 by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1/CA (for the generation of shared secret and for the derivation of the new session keys) and FCS_COP.1/CA_ENC, FCS_COP.1/CA_MAC (for the ENC_MAC_Mode secure messaging). The session keys are destroyed according to FCS_CKM.4 after use. The SFRs FMT_MTD.1/CAPK, FMT_MTD.1/AAPK, and FMT_MTD.1/KEY_READ require that the Chip Authentication Key and Active Authentication key cannot be written unauthorized or read afterwards. The SFR FCS_RND.1 represents a general support for cryptographic operations needed. The security objective OT.Data_Authenticity aims ensuring authenticity of the User- and TSF data (after the PACE Authentication or Active Authentication) by enabling its verification at the terminal-side (PACE) and by an active verification by the TOE itself (PACE and Active Authentication). This objective is mainly achieved by FTP_ITC.1/PACE using FCS_COP.1/PACE_MAC, as well as FTP_ITC.1/CPS. A prerequisite for establishing the trusted channel in the Operational Use phase is a successful PACE or Chip and Terminal Authentication v.1 (FIA_UID.1/PACE, FIA_UAU.1/PACE) using FCS_CKM.1/DH_PACE resp. FCS_CKM.1/CA and possessing the special properties FIA_UAU.5/PACE, FIA_UAU.6/PACE resp. FIA_UAU.6/EAC/CAV1, FIA_UAU.6/EAC/CAM. A prerequisite for establishing the trusted channel in Pre-personalization and in Personalization is a successful CPS authentication using FCS_CKM.1/CPS. FDP_RIP.1 requires erasing the values of session keys (here for KMAC). FIA_UAU.4/PACE, FIA_UAU.5/PACE, and FCS_CKM.4 represent some required specific properties of the protocols used. The SFR FMT_MTD.1/KEY_READ restricts the access to the PACE passwords and the Chip Authentication Private Key. FMT_MTD.1/PA requires that SOD containing signature over the User Data stored on the TOE and used for the Passive Authentication is allowed to be written by the Personalization Agent only and, hence, is to be considered as trustworthy. The SFR FCS_RND.1 represents a general support for cryptographic operations needed. The SFRs FMT_SMF.1 and FMT_SMR.1/PACE support the functions and roles related. The security objective OT.Data_Authenticity is also achieved by FCS_COP.1/AA_SIGN/RSA and FCS_COP.1/AA_SIGN/ECDSA. The security objective OT.Data_Confidentiality aims that the TOE always ensures confidentiality of the User- and TSF-data stored and, after the PACE Authentication resp. Chip Authentication, of these data exchanged. This objective for the data stored is mainly achieved by FDP_ACC.1/TRM and FDP_ACF.1/TRM. FIA_UAU.4/PACE, FIA_UAU.5/PACE, and FCS_CKM.4 represent some required specific properties of the protocols used. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 142 of 177 This objective for the data exchanged is mainly achieved by FDP_UCT.1/TRM, FDP_UIT.1/TRM, and FTP_ITC.1/PACE using FCS_COP.1/PACE_ENC resp. FCS_COP.1/CA_ENC, as well as by FTP_ITC.1/CPS. A prerequisite for establishing this trusted channel is a successful PACE or Chip and Terminal Authentication v.1 (FIA_UID.1/PACE, FIA_UAU.1/PACE) using FCS_CKM.1/DH_PACE resp. FCS_CKM.1/CA and possessing the special properties FIA_UAU.5/PACE, FIA_UAU.6/PACE resp. FIA_UAU.6/EAC/CAV1, FIA_UAU.6/EAC/CAM. FDP_RIP.1 requires erasing the values of session keys (here for KENC). The SFR FMT_MTD.1/KEY_READ restricts the access to the PACE passwords and the Chip Authentication Private Key. FMT_MTD.1/PA requires that SOD containing signature over the User Data stored on the TOE and used for the Passive Authentication is allowed to be written by the Personalization Agent only and, hence, is to be considered trustworthy. The SFR FCS_RND.1 represents the general support for cryptographic operations needed. The SFRs FMT_SMF.1 and FMT_SMR.1/PACE support the functions and roles related. The security objective OT.Sense_Data_Conf “Confidentiality of sensitive biometric reference data” is enforced by the Access Control SFP defined in FDP_ACC.1/TRM and FDP_ACF.1/TRM allowing the data of EF.DG3 and EF.DG4 only to be read by successfully authenticated Extended Inspection System being authorized by a valid certificate according FCS_COP.1/SIG_VER. The SFRs FIA_UID.1/PACE and FIA_UAU.1/PACE require the identification and authentication of the inspection systems. The SFR FIA_UAU.5/PACE requires the successful Chip Authentication (CA) performed as part of PACE-CAM or as Chip Authentication Protocol v.1 before any authentication attempt as Extended Inspection System. During the protected communication following the CA, the reuse of authentication data is prevented by FIA_UAU.4/PACE. The SFRs FIA_UAU.6/EAC/CAV1, FIA_UAU.6/EAC/CAM, and FDP_UCT.1/TRM requires the confidentiality protection of the transmitted data after Chip Authentication by means of secure messaging implemented by the cryptographic functions according to FCS_RND.1 (for the generation of the terminal authentication challenge), FCS_CKM.1/CA (for the generation of shared secret and for the derivation of the new session keys), and FCS_COP.1/CA_ENC, FCS_COP.1/CA_MAC (for ENC_MAC_Mode secure messaging). The session keys are destroyed according to FCS_CKM.4 after use. The SFRs FMT_MTD.1/CAPK and FMT_MTD.1/KEY_READ require that the Chip Authentication Key cannot be written unauthorized or read afterwards. To allow a verification of the certificate chain as in FMT_MTD.3, the CVCA’s public key and certificate as well as the current date are written or updated by authorized identified role as of FMT_MTD.1/CVCA_INI, FMT_MTD.1/CVCA_UPD, and FMT_MTD.1/DATE. The security objective OT.Chip_Auth_Proof “Proof of e-Document’s chip authenticity” is ensured by the Chip Authentication provided by FIA_API.1/CAV1 or FIA_API.1/CAM (depending on the Chip Authentication protocol used) proving the identity of the TOE. The CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 143 of 177 Chip Authentication defined by FCS_CKM.1/CA is performed using a TOE internally stored confidential private key as required by FMT_MTD.1/CAPK and FMT_MTD.1/KEY_READ. Chip Authentication, performed as part of PACE-CAM [R30] or by Chip Authentication Protocol v.1 [R6], requires additional TSF according to FCS_CKM.1/CA (for the derivation of the session keys) and FCS_COP.1/CA_ENC, FCS_COP.1/CA_MAC (for the ENC_MAC_Mode secure messaging). The SFRs FMT_SMF.1 and FMT_SMR.1/PACE support the functions and roles related. The security objective OT.Active_Auth_Proof “Proof of e-Document’s chip authenticity” is ensured by the Active Authentication Mechanism [R30] provided by FIA_API.1/AA, proving the identity of the TOE. The Active Authentication Protocol defined by FIA_API.1/AA is performed using a TOE internally stored confidential private key as required by FMT_MTD.1/AAPK and FMT_MTD.1/KEY_READ. This key is written to the TOE as defined by FMT_MTD.1/AAPK. The Active Authentication Protocol requires additional TSF according to FCS_COP.1/AA_SIGN/RSA and FCS_COP.1/AA_SIGN/ECDSA (for the digital signature of Active Authentication data). The security objective OT.Prot_Abuse-Func “Protection against Abuse of Functionality” is ensured by the SFRs FMT_LIM.1 and FMT_LIM.2, which prevent misuse of test functionality of the TOE or other features which may not be used after TOE Delivery. The security objective OT.Prot_Inf_Leak “Protection against Information Leakage” requires the TOE to protect confidential TSF data stored and/or processed in the e-Document’s chip against disclosure: • by measurement and analysis of the shape and amplitude of signals or the time between events found by measuring signals on the electromagnetic field, power consumption, clock, or I/O lines, which is addressed by the SFR FPT_EMS.1, • by forcing a malfunction of the TOE, which is addressed by the SFRs FPT_FLS.1 and FPT_TST.1, and/or • by a physical manipulation of the TOE, which is addressed by the SFR FPT_PHP.3. The security objective OT.Tracing aims that the TOE prevents gathering TOE tracing data by means of unambiguous identifying the e-Document directly through establishing a communication via the contact interface, or remotely through establishing or listening to a communication via the contactless interface of the TOE, without a priori knowledge of the correct values of the shared authentication data (Pre-personalization keys, Personalization keys, PACE passwords). This objective is achieved as follows: • while establishing communication in pre-operational phases by FIA_AFL.1/Pre-pers, FIA_AFL.1/Pers; • while establishing PACE communication with a PACE password, e.g. CAN or MRZ (non-blocking authorization data) – by FIA_AFL.1/PACE; CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 144 of 177 • for listening to PACE communication (of importance for the current ST, since SOD is card-individual) – by FTP_ITC.1/PACE. The security objective OT.Prot_Phys-Tamper “Protection against Physical Tampering” is covered by the SFR FPT_PHP.3. The security objective OT.Prot_Malfunction “Protection against Malfunctions” is covered by (i) the SFR FPT_TST.1, which requires self-tests to demonstrate the correct operation and tests of authorized users to verify the integrity of TSF data and TSF code, and (ii) the SFR FPT_FLS.1, which requires a secure state in case of detected failure or operating conditions possibly causing a malfunction. 8.2 Dependency rationale The dependency analysis for the security functional requirements shows that the basis for mutual support and internal consistency between all defined functional requirements is satisfied. All dependencies between the chosen functional components are analysed, and non-dissolved dependencies are appropriately explained. Table 8-2 shows the dependencies between the SFRs of the TOE.

No management of these security attributes (i.e. SFRs FMT_MSA.1 and FMT_MSA.3) is necessary here. Justification 2: Since AA does not provide for the generation or destruction of cryptographic keys, neither the SFR FCS_CKM.1 nor the SFR FCS_CKM.4 apply. Justification 3: The SFR FCS_COP.1/AUTH refers to the symmetric Pre- personalization Key and Personalization Key permanently stored, respectively, during IC manufacturing and pre-personalization (cf. FMT_MTD.1/INI_ENA) by the Manufacturer. Thus, there is no necessity to generate or import these keys during the addressed TOE life cycle by the means of FCS_CKM.1 or FDP_ITC. Since these keys are permanently stored within the TOE, there is no need for FCS_CKM.4, too. 8.3 Security assurance requirements rationale The EAL5 was chosen to permit a developer to gain maximum assurance from positive security engineering based on good commercial development practices which, though rigorous, do not require substantial specialist knowledge, skills, and other resources. EAL5 is applicable in those circumstances where developers or users require a moderate to high level of independently assured security in conventional commodity TOEs and are prepared to incur sensitive security specific engineering costs. The selection of the component ALC_DVS.2 provides a higher assurance of the security of the e-Document’s development and manufacturing, especially for the secure handling of the e-Document’s material. The selection of the component AVA_VAN.5 provides a higher assurance of the security by vulnerability analysis to assess the resistance to penetration attacks performed by an attacker possessing a high attack potential. This vulnerability analysis is necessary to fulfil the security objectives OT.Sens_Data_Conf and OT.Chip_Auth_Proof. The component ALC_DVS.2 has no dependencies on other assurance requirements. The component AVA_VAN.5 depends on: • ADV_ARC.1, Security architectural description • ADV_FSP.4, Complete functional specification • ADV_TDS.3, Basic modular design CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 148 of 177 • ADV_IMP.1, Implementation representation of the TSF • AGD_OPE.1, Operational user guidance • AGD_PRE.1, Preparative procedures • ATE_DPT.1, Testing: basic design All of these are met or exceeded in the EAL5 assurance package. 8.4 Security requirements – Mutual support and internal consistency The following part of the security requirements rationale shows that the set of security requirements for the TOE consisting of the security functional requirements (SFRs) and the security assurance requirements (SARs) together form a mutually supportive and internally consistent whole. The analysis of the TOE’s security requirements with regard to their mutual support and internal consistency demonstrates what follows. The dependency analysis in section 8.2 “Dependency rationale” shows that the basis for mutual support and internal consistency between all defined functional requirements is satisfied. All dependencies between the chosen functional components are analysed, and non-satisfied dependencies are appropriately explained. All subjects and objects addressed by more than one SFR in section 6 “Security functional requirements” are also treated in a consistent way: the SFRs impacting them do not require any contradictory property and behaviour of these “shared” items. The assurance class EAL5 is an established set of mutually supportive and internally consistent assurance requirements. The dependency analysis for the sensitive assurance components in section 8.3 “Security assurance requirements rationale” shows that the assurance requirements are mutually supportive and internally consistent as all (sensitive) dependencies are satisfied and no inconsistency appears. Inconsistency between functional and assurance requirements could only arise if there are functional assurance dependencies which are not met, a possibility which has been shown not to arise in section 8.2 “Dependency rationale” and 8.3 “Security assurance requirements rationale”. Furthermore, as also discussed in section 8.3 “Security assurance requirements rationale”, the chosen assurance components are adequate for the functionality of the TOE. Therefore, the assurance requirements and security functional requirements support each other and there are no inconsistencies between the goals of these two groups of security requirements.

Table 9-1 Implementation of the security functional requirements in the TOE Security functional requirement Implementation FAU_SAS.1 The Manufacturer stores IC identification data in the audit records. FCS_CKM.1/CPS The TOE generates session keys for Secure Messaging soon after a successful CPS authentication of the Pre- personalization Agent or the Personalization Agent, as described in section 5.2 of EMV specification [R12]. See Application Note 32. FCS_CKM.1/DH_PACE The TOE generates session keys for Secure Messaging soon after a successful PACE or PACE-CAM authentication of the inspection terminal. See Application Note 33, Application Note 34. FCS_CKM.1/CA The TOE generates session keys for Secure Messaging soon after a successful Chip Authentication v1 of the inspection terminal. See Application Note 36, Application Note 37 and Application Note 38. FCS_CKM.4 Session keys are overwritten with zeros when a Secure Messaging session is closed. See Application Note 41. FCS_COP.1/PACE_ENC During a Secure Messaging session after a PACE authentication, the TOE encrypts transmitted data to ensure confidentiality, and decrypts received data, to restore original content. To this end, the TOE uses Triple-DES in CBC mode with 112-bit session key or AES with 128, 192 or 256 bit keys. See Application Note 53 and Application Note 54. FCS_COP.1/PACE_MAC During a Secure Messaging session after a PACE authentication, the TOE computes a Message Authentication Code (MAC) to check integrity of received data, and to allow integrity check by the terminal. The MAC computation is performed according to CMAC or Retail MAC algorithm and cryptographic key sizes 112, 128, 192 or 256 bits. See Application Note 55.

FPT_EMS.1 Leakage of confidential data through side channels is prevented by the security features of both the IC and the OS, in accordance with the security recommendations contained in the IC guidance documentation [R48][R49][R50]. FPT_FLS.1 In case self-test fails or a physical attack is detected, the OS enters an endless loop, so that all cryptographic operations and data output interfaces are inhibited. CELES-c002 Security Target EAC-PACE-AA ICAO Application – Public Version ASE Version: 1.0 Date: 2020-10-15 Reference: TCLE190028 page 157 of 177 Security functional requirement Implementation FPT_TST.1 During initial start-up, the IC performs a self-test procedure that tests alarm lines and environmental sensor mechanisms (cf. [R48]), and the OS checks the integrity of the TSF by computing a hash value of the code and comparing it with a reference hash value stored internally. Moreover, the integrity of TSF data is checked whenever they are used. In case any one of such checks fails, the OS enters an endless loop, so that the resulting fall of communication informs the user about the integrity error. See also Application Note 112, Application Note 113 and Application Note 114. FPT_PHP.3 Detection of physical attacks is ensured by the security features of both the IC and the OS, in accordance with the security recommendations contained in the IC guidance documentation [R48][R49][R50]. 9.2 Assurance measures Assurance measures applied to the TOE are fully compliant to those described in part 3 of the Common Criteria v3.1 [R11]. The implementation is based on a description of the security architecture of the TOE and on a semi-formal high-level and low-level design of the components of the TOE. The description is sufficient to generate the TOE without other design requirements. These documents, together with the source code of the software, address the ADV_ARC, ADV_FSP, ADV_TDS and ADV_IMP families. The configuration management plan addresses the ALC_CMC and ALC_CMS families and enforces good practices to securely manage configuration items including, but not limiting to, design documentation, user documentation, source code, test documentation and test data. The configuration management process guarantees the separation of the development configuration libraries from the configuration library containing the releases and also supports the generation of the TOE. All the configuration items are managed with the help of automated tools. In particular configuration items regarding security flaws are managed with the support of an issue tracking system, while all the other configuration items are managed with the help of a version control system. The software test process, addressing the class ATE, is machine-assisted to guarantee a repeatable error-free execution of the same test chains in both the system test and in the validation phases.

The prevention measures, the checks and all the actions to be performed at the developer’s site are described in the secure delivery procedure addressing the family ALC_DEL, while the security measures related to delivery to be applied at the user’s site are defined in the pre- personalization guidance. The latter document also addresses the family AGD_PRE. The necessary information for the document personalization is provided by a dedicated guidance and the information for its usage after delivery to the legitimate holder is provided by the guidance for the operational use. These documents address the AGD_OPE assurance family. To protect the confidentiality and integrity of the TOE design and implementation, the development and production environment and tools conform to the security policies defined in the documentation dedicated to the development security, which addresses the family ALC_DVS. The life-cycle model adopted in the manufacturing phases and the tools supporting the development and production of the TOE are described in dedicated documents addressing the families ALC_LCD and ALC_TAT. An independent vulnerability analysis, meeting requirements of the family AVA_VAN, is conducted by a third party. Due to the composite nature of the evaluation, which is based on the CC evaluation of the hardware, the assurance measures related to the platform (IC) are covered by documents from the IC manufacturer.
