TOE definition The TOE comprises: IDentity Applet v.3.4/BAC/AA Security Target Page 7 of 96 I. Underlying platform of the TOE, which is evaluated by Brightsight and certified by TÜV Rheinland Nederland B.V. at assurance level Evaluation assurance level: EAL6 augmented by ASE_TSS.2 and ALC_FLR.1. CC Certification number: NSCIB-CC-180212-CR3 Long platform name: JCOP 4 P71 Short name: JCOP 4 It consists of: a) Micro Controller (a secure smart card controller from NXP from the SmartMX3 family); b) IC Dedicated Software (MC FW Micro Controller Firmware and Crypto Library); c) IC Embedded Software JCOP4 (Java Card Virtual Machine, Runtime Environment, Java Card API; d) Global Platform (GP) Framework; II. the Application Part of the TOE: ID&Trust IDentity Applet Suite v3.4/BAC; III. the associated guidance documentation [5], [6]. The PP-0055 [17] refers to the TOE as MRTD, Machine Readable Travel Documents or Travel Document. In order to facilitate the better usage, the terminology is not changed in the current ST. 1.3.2. TOE usage and major security features The TOE is a contactless integrated circuit chip with IC Dedicated Software (Micro Controller Firmware, Crypto Library), Embedded Software (JCOP4) and IDentity Applet v3.4/BAC, containing components for a machine readable travel document (MRTD’s chip) programmed according to the Logical Data Structure (LDS) and providing the Basic Access Control according to [9] and [13] and optionally Active Authentication defined by [13]. IDentity Applet Suite v3.4 is a highly configurable eID solution. It is able to satisfy multiple different application requirements even within a single applet instance. The Application part of the TOE, the applet functionalities are distributed according to the following table: Application Function Standard Protection Profile IDentity/PKI Flexible PKI token CEN TS 14890-1/2 IAS-ECC 1.0.1 [24] - IDentity/IAS European card for e- Services and National e- ID applications CEN/TS 15480-2 [23] IAS-ECC 1.0.1[24] - IDentity/QSCD Qualified Signature Creation Device CEN/TS 15480-2 [23] IAS-ECC 1.0.1 [24] [20] [21] IDentity Applet v.3.4/BAC/AA Security Target Page 8 of 96 Table 1 IDentity Applet Suite v3.4 functionalities All the functions are supplied by the applet “ID&Trust IDentity Suite Version 3.4”, the behaviour of the applet changes according to the configuration applied during the personalization phase and the environmental behaviour of the usage phase. The scope of the current ST is only concerned with applet behaviour of configuration IDentity/BAC. For the TOE, beside the eMRTD application other applications may be present on the JCOP4. They are not relevant for the current ST and do not infer the Security Functions of the TOE. The TOE utilizes the evaluation of the underlying JCOP4. The intended customer of the product is the Card Issuer, who is in charge of the issuance of the product to the smartcard holders. Application note 1 (ST author) Operational mode of the TOE depends on the decided operation of the Inspection System. IDentity Applet can work using BAC or PACE with EAC authentication also. If the Inspection System uses PACE with EAC, the TOE supports it. Nevertheless, this ST addresses the Basic Access Control only. PACE with EAC is out of the scope of this ST, and it is described in another ST.

TOE Type The TOE is a contactless integrated circuit chip with IC Dedicated Software (Micro Controller Firmware, Crypto Library), Embedded Software (JCOP4) and IDentity Applet v3.4/BAC. 1.3.4 Non-TOE hardware/software/firmware 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 operating system and application. Note, the inlay holding the chip as well as the antenna and the booklet (holding the printed MRZ) are needed to represent a complete travel document, nevertheless these parts are not inevitable for the secure operation of the TOE 1.4. TOE description 1.4.1. Product type The TOE is a contactless integrated circuit chip with IC Dedicated Software (Micro Controller Firmware, Crypto Library), Embedded Software (JCOP 4) and IDentity Applet v3.4/BAC, viewed as unit of 1) the physical part of the travel document in form of paper and/or plastic and chip. It presents visual readable data including (but not limited to) personal data of the travel document holder: a) the biographical data on the biographical data page of the travel document surface, b) the printed data in the Machine-Readable Zone (MRZ) and c) the printed portrait. 2) the logical travel document as data of the travel document holder stored according to the Logical Data Structure as defined in [14] as specified by ICAO on the contact based or contactless integrated circuit. It presents contact based / contactless readable data including (but not limited to) personal data of the travel document holder a) the digital Machine-Readable Zone Data (digital MRZ data, EF.DG1), b) the digitized portraits (EF.DG2), c) the biometric reference data of finger(s) (EF.DG3) or iris image(s) (EF.DG4) or both d) the other data according to LDS (EF.DG5 to EF.DG16) and e) the Document Security Object (SOD). Application note 2 (ST author) The biometric reference data (EF.DG3 and EF.DG4) are optional according to [13]. If the issuing State or Organisation uses this option, it should protect these data by means of Extended Access Control (EAC1). EAC1 is out of scope of this ST and is described in another ST. According to the current ST the TOE prevents read access to sensitive User Data (the biometric reference data of finger(s) (EF.DG3) or iris image(s) (EF.DG4)). 1.4.2. Components of the TOE Micro Controller The Micro Controller is a secure smart card controller from NXP from the SmartMX3 family. The Micro Controller contains a co-processor for symmetric cipher, supporting DES operations and AES, as well as an accelerator for asymmetric algorithms. The Micro Controller further contains a physical random number IDentity Applet v.3.4/BAC/AA Security Target Page 10 of 96 generator. The supported memory technologies are volatile (Random Access Memory (RAM)) and non- volatile (Read Only Memory (ROM) and FLASH) memory. Access to all memory types is controlled by a Memory Management Unit (MMU) which allows to separate and restrict access to parts of the memory. IC dedicated software - Micro Controller Firmware The Micro Controller Firmware is used for testing of the Micro Controller at production, for booting of the Micro Controller after power-up or after reset, for configuration of communication devices and for writing data to non-volatile memory. IC dedicated software - Crypto Library The Crypto Library provides implementations for symmetric and asymmetric cryptographic operations, hashing, the generation of hybrid deterministic and hybrid physical random numbers and further tools like secure copy and compare. The supported asymmetric cryptographic operations are ECC and RSA. These algorithms use the Public Key Crypto Coprocessor (PKCC) of the Micro Controller for the cryptographic operations. Micro Controller, IC dedicated software (Micro Controller Firmware, Crypto Library) are covered by the following certification: Certification ID: BSI-DSZ-CC-1136-2021 Evaluation level EAL6+ ALC_FLR.1 and ASE_TSS.2 according to Security IC Platform Protection Profile with Augmentation Packages Version 1.0, 13 January 2014, BSI-CC-00084-2014.

For details please see: section 1.4.4 TOE life cycle and [5]. The boxes marked with white are not certified. 1.4.3. TOE usage and security features for operational use A State or Organisation issues travel documents to be used by the holder for international travel. The traveller presents a travel document to the inspection system to prove his or her identity. The travel document in context of this security target contains: 2 The AGD documents provided in electronic document format. IDentity Applet v.3.4/BAC/AA Security Target Page 12 of 96 (i) visual (eye readable) biographical data and portrait of the holder, (ii) a separate data summary (MRZ data) for visual and machine reading using OCR methods in the Machine readable zone (MRZ) and (iii) data elements on the travel document’s chip according to LDS in case of contactless machine reading. The authentication of the traveller is based on (iv) the possession of a valid travel document personalised for a holder with the claimed identity as given on the biographical data page and (v) biometrics using the reference data stored in the travel document. The issuing State or Organisation ensures the authenticity of the data of genuine travel documents. The receiving State trusts a genuine travel document of an issuing State or Organisation. For this security target the travel document is viewed as unit of 1) The physical part of the travel document in form of paper and/or plastic and chip. It presents visual readable data including (but not limited to) personal data of the travel document holder a) the biographical data on the biographical data page of the travel document surface, b) the printed data in the Machine Readable Zone (MRZ) and c) the printed portrait. 2) the logical travel document as data of the travel document holder stored according to the Logical Data Structure as defined in [13] as specified by ICAO on the contact based or contactless integrated circuit. It presents contact based / contactless readable data including (but not limited to) personal data of the travel document holder: a) the digital Machine Readable Zone Data (digital MRZ data, EF.DG1), b) the digitized portraits (EF.DG2), c) the optional biometric reference data of finger(s) (EF.DG3) or iris image(s) (EF.DG4) or both d) the other data according to LDS (EF.DG5 to EF.DG16) and e) the Document Security Object (SOD). The issuing State or Organisation implements security features of the travel document to maintain the authenticity and integrity of the travel document and their data. The physical part of the travel document and the travel document’s chip are identified by the Document Number. The physical part of the travel document is protected by physical security measures (e.g. watermark, security printing), logical (e.g. authentication keys of the travel document’s chip) and organisational security measures (e.g. control of materials, personalisation procedures) [14]. These security measures can include the binding of the travel document’s chip to the travel document. The logical travel document is protected in authenticity and integrity by a digital signature created by the document signer acting for the issuing State or Organisation and the security features of the travel document’s chip. The ICAO defines the baseline security methods Passive Authentication and the optional advanced security methods Basic Access Control to the logical travel document, ‘ICAO Doc 9303’ [13]. IDentity Applet v.3.4/BAC/AA Security Target Page 13 of 96 This security target addresses the protection of the logical travel document: (i) In integrity by write-only-once access control and by physical means, and (ii) in confidentiality by the Basic Access Control Mechanism. This security target does not address the Extended Access Control as optional security mechanisms. The TOE support the Active Authentication (defined by [13]) as an optional security mechanism The Active Authentication enables to the inspection system to verify that the TOE chip is genuine, based on a static key pair (Active Authentication Key Pair) stored in the chip. The Basic Access Control is a security feature which is mandatory supported by the TOE. The inspection system: (iii) Reads optically the MRTD, (iv) authenticates itself as inspection system by means of Document Basic Access Keys. After successful authentication of the inspection system the MRTD’s chip provides read access to the logical MRTD by means of private communication (secure messaging) with this inspection system according to [14]. 1.4.4. TOE life cycle The TOE life cycle is described in terms of the four life cycle phases. (With respect to the [15], the TOE life cycle the life-cycle is additionally subdivided into 7 steps.) Application note 3 (from ST Author) The IDentity Applet Life cycle has the following phases, which differ from the whole TOE Life cycle: • IDentity Applet LOADED (Creation phase) • IDentity Instance Personalization Phase SELECTABLE (Configuration Phase) CONFIGURED (Initialization Phase) Operational Phase PERSONALIZED LOCKED BLOCKED These phases are detailed in the ID&Trust IDentity Applet Suite Administrator’s Guide [5]. These states and phases are presented here, because of informational reasons, to serve better understanding. Phase 1 of TOE life-cycle “Development” IDentity Applet v.3.4/BAC/AA Security Target Page 14 of 96 (Step1) The TOE is developed in phase 1. The IC developer develops the integrated circuit, the IC Dedicated Software (i.e. Crypto Library) and the guidance documentation associated with these TOE components. (Step2) IC developer uses the guidance documentation for the integrated circuit and the guidance documentation for relevant parts of the IC Dedicated Software and develops the IC Embedded Software (operating system). The IDentity Applet v3.4/BAC and the corresponding guidance documentation are developed by ID&Trust Ltd. The manufacturing documentation of the IC including the IC Dedicated Software and the Embedded Software and the IDentity Applet v3.4/BAC in the non-volatile non-programmable memories and in FLASH is securely delivered to the IC manufacturer. Part of the IC Embedded Software is in the non-volatile non- programmable memories, and the guidance documentation is securely delivered to the travel document manufacturer. Application note 4 (from ST author) The delivery procedures between ID&Trust (applet developer) and the manufacturer: 1. The IDentity Applet Developer develops a new version of the ID&Trust IDentity Applet v3.4/BAC. 2. After the new version is tested a new release is issued and stored in configuration management system. 3. The new version of the IDentity Applet v3.4 is sent to as required by [27]. Phase 2 of TOE life cycle “Manufacturing” (Step3) In a first step the TOE integrated circuit is produced containing the travel document’s chip Dedicated Software and the parts of the travel document’s chip Embedded Software in the non-volatile non-programmable memories (ROM) and the IDentity Applet Suite v3.4 uploaded to FLASH. The IC manufacturer writes the IC Identification Data onto the chip to control the IC as travel document material during the IC manufacturing and the delivery process to the travel document manufacturer. The IC is securely delivered from the IC manufacture to the travel document manufacturer. (Step4 optional) The travel document manufacturer combines the IC with hardware for the contact based/contactless interface in the travel document. (Step5) The MRTD manufacturer (i) (may) creates the MRTD application and (ii) equips MRTD’s chips with pre-personalization data. Application note 5 (redefined for the goals of this ST by the ST author, taken from Application note 1 from [18]): Creation of the application implies that the Creation Phase of the IDentity Applet is closed, and the IDentity Applet gets to SELECTABLE state (Configuration Phase). Further details are discussed within the IDentity Applet Administrator’s Guide [5]. The pre-personalised travel document together with the IC Identifier is securely delivered from the travel document manufacturer to the Personalisation Agent. The travel document manufacturer also provides the relevant parts of the guidance documentation to the Personalisation Agent. IDentity Applet v.3.4/BAC/AA Security Target Page 15 of 96 The Personalization Agent Authentication Keys are the preinstalled keys for the IDentity Applet, which are preinstalled by the Travel Document Manufacturer, and which are needed and used in the Personalization process. Phase 3 of TOE life-cycle “Personalisation of the travel document” (Step6) The personalisation of the travel document includes: I. the survey of the travel document holder’s biographical data, II. the enrolment of the travel document holder biometric reference data (i.e. the digitized portraits and the optional biometric reference data), III. the printing of the visual readable data onto the physical part of the travel document, IV. the writing of the TOE User Data and TSF Data into the logical travel document and V. configuration of the TSF if necessary. The step (iv) is performed by the Personalisation Agent and 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. Application note 6 (of the ST author) The Personalisation Phase of the IDentity Applet contains the Configuration and Initialisation Phase. During Configuration phase all applications, files, security data objects, configuration variables, file and object parameters are created. Specified settings in the configuration phase fundamentally determine the Application Profile, which is protected by the Application Profile Signature. In the Initialisation Phase the content of the IDentity Applet instance is loaded. The signing of the Document Security Object by the Document Signer is crucial in this phase since the signature of the Document Security Object supports to verify genuineness of the MRTD’s chip (DG.15 with Active Authentication). The referred Personalization Agent can be the Card Issuer, or a different contributor on the Card Issuer discretion. These phases are detailed in the ID&Trust IDentity Applet Suite Administrator’s Guide [5]. These states and phases are presented here for informational reasons, to serve better understanding. Application note 7 (taken from application note 2 from [18]) The TSF data (data created by and for the TOE, that might affect the operation of the TOE; cf. [1] §92) comprise (but are not limited to) the Personalization Agent Authentication Key(s) and the Basic Authentication Control Key. Phase 4 of the TOE life-cycle “Operational Use” (Step7) The TOE is used as a travel document's chip by the traveller and the inspection systems in the “Operational Use” phase. The user data can be read according to the security policy of the issuing State or Organization and can be used according to the security policy of the issuing State, but they can never be modified. IDentity Applet v.3.4/BAC/AA Security Target Page 16 of 96 Application note 8 (taken from application note 4 from [17])) The authorized Personalization Agents might be allowed to add (not to modify) data in the other data groups of the MRTD application (e.g. person(s) to notify EF.DG16) in the Phase 4 “Operational Use”. This will imply an update of the Document Security Object including the re-signing by the Document Signer. Application note 9 (taken from application note 5 from [17]) The intention of the ST is to consider at least the phases 1 and parts of phase 2 (i.e. Step1 to Step3) as part of the evaluation and therefore to define the TOE delivery according to CC after this phase. Since specific production steps of phase 2 are of minor security relevance (e.g. booklet manufacturing and antenna integration) these are not part of the CC evaluation under ALC. Nevertheless, the decision about this has to be taken by the certification body resp. the national body of the issuing State or Organization. In this case the national body of the issuing State or Organization is responsible for these specific production steps. Note that the personalisation 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, the Security Target has to outline 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 4 in Phase 2 may also take place in the Phase 3. 1.4.5. TOE security functions The following TOE ensured security functions are the most significant for its operational use: • Only entities (e.g. terminals) possessing authorisation can get access to the user data stored on the TOE and use security functionality of the travel document under control of the travel document holder, • Verifying authenticity and integrity as well as securing confidentiality of user data in the communication channel between the TOE and the entity connected, • Averting of inconspicuous tracing of the travel document, • Self-protection of the TOE security functionality and the data stored inside. Above mentioned functions are described below informally, and in detail in section 7.1. 1.4.6. Features of the IDentity Applet This section is informational and intended to provide a general detail about the IDentity Applet which is the essential part of this ST. Information in this section does not extend the TOE description or claims of this ST. IDentity Applet may be considered as a highly secure and configurable multi-application cryptographic smart card framework for PKI and e-ID purposes. IDentity Applet complies with the standards referenced in TOE Overview. The API exposed by IDentity Applet allows fast development of cryptographic supported applications for National ID, ePassport, Enterprise ID, Healthcare, Transportation, and Payment applications.

PP Claim The current ST claims strict conformance to the following Protection Profile: Title: Protection Profile — Machine Readable Travel Document with ICAO Application and Basic Access Control (MRTD-PP) [17] Sponsor: Bundesamt für Sicherheit in der Informationstechnik CC Version: 3.1 (Revision 2) Assurance Level: The minimum assurance level for this PP is EAL4 augmented. General Status: Final Version Number: 1.10 Registration: BSI-CC-PP-0055 Keywords: ICAO, machine readable travel document, basic access control 2.3. Package Claim This ST is conforming to assurance package EAL4 augmented with ALC_DVS.2 defined in CC part 3 [3]. 2.4. Conformance rationale The security target claims strict conformance to one PP ([17]). This ST is conformant with Common Criteria Part 2 [2] extended due to additional components as stated in Protection Profile named above in the PP claim. IDentity Applet v.3.4/BAC/AA Security Target Page 19 of 96 This ST is conformant to Common Criteria Part 3 [3] The TOE is consistent with the TOE type in the PP. The security problem definition of this security target is consistent with the statement of the security problem definition in the PP, as the security target claims strict conformance to the PP. All assignments and selections of the security functional requirements defined in the [17] are done accordingly. There is one threat added: • T.Counterfeit. Justification: T.Counterfeit is added because of the optional function of the TOE (Active Authentication). This threat does not affect the strict conformance. The security objectives for the TOE of this security target are consistent with the statement of the security objectives in the PP as the security target claims strict conformance to the PP. There is one security objective added: • OT.Active_Auth_Proof (Proof of travel document’s chip authenticity). Justification: OT.Active_Auth_Proof is added because of the optional function of the TOE (Active Authentication). This security objective does not affect the strict conformance. The security objectives for the operational environment in this security target include all security objectives for the operational environment from the PP. There is one objective added: • OE.Active_Auth_Key_Travel_Document (Travel document Active Authentication Key). Justification: OE.Active_Auth_Key_Travel_Document is added because of the optional function of the TOE (Active Authentication). This security objectives do not affect the strict conformance. The security requirements of this ST are consistent with the statement of the security requirements in the [17] as the ST claims strict conformance to the [17]. There is the following SFRs added from sec. 6.1 in this security target: FIA_API.1/AA, The following SFRs were iterated from [2]: • FCS_CKM.1/AA_GEN • FMT_MTD.1/AAPK • FCS_COP.1/EMRTD. Two existing SFRs were extended for the inclusion of the Active Authentication private key: • FMT_MTD.1/KEY_READ, and • FPT_EMS.1. IDentity Applet v.3.4/BAC/AA Security Target Page 20 of 96 Justification: The above-mentioned addition, iterations and extensions are necessary because of the optional function of the TOE (Active Authentication). These additional SFRs do not affect the strict conformance. All assignments and selections of the security functional requirements are defined in the [17] section 6.1 and in this security target section 6.1. 2.5. Statement of compatibility 2.5.1. Security Functionalities The following table contains the security functionalities of the Platform-ST [7] and of this ST, showing which Functionality correspond to the Platform-ST [7] and which has no correspondence. This statement is compliant to the requirements of [8]. A classification of TSFs of the Platform-ST [7] has been made. Each TSF has been classified as ‘relevant’ or ‘not relevant’ for this ST.

As described in [17] the purpose of these SFRs is to prevent misuse of test features of the TOE over the life cycle phases. According to [7] the Platform consists of the Micro Controller, Crypto Library and Operation System, which are certified as well. By the Micro Controller the limited availability and capability of test features are ensured after Manufacturing phase of the TOE. FMT_LIM.1 and FMT_LIM.2 are covered by the following Security Function of Micro Controller ST: TSF.Control. For details please check [32] To sum up the above-mentioned Security Function of Micro Controller ensures that the test features of TOE cannot be misused. The Personalization Agent (FMT_SMR.1) may use the GlobalPlatform function of the Platform. 2.5.5. Assurance requirements This ST requires EAL 4 according to Common Criteria V3.1 R5 augmented by ALC_DVS.2. The Platform-ST [7] requires EAL 6 according to Common Criteria V3.1 R5 augmented by: ASE_TSS.2 and ALC_FLR.1. As EAL 6 covers all assurance requirements of EAL 4 all non-augmented parts of this ST will match to the Platform-ST [7] assurance requirements. 2.6. Analysis Overall there is no conflict between security requirements of this ST and the Platform-ST [7]. IDentity Applet v.3.4/BAC/AA Security Target Page 29 of 96 3. Security Problem Definition 3.1. Assets The assets to be protected by the TOE include the User Data on the MRTD’s chip. Logical MRTD Data The logical MRTD data consists of the EF.COM, EF.DG1 to EF.DG16 (with different security needs) and the Document Security Object EF.SOD according to LDS [14]. These data are user data of the TOE. The EF.COM lists the existing elementary files (EF) with the user data. The EF.DG1 to EF.DG13 and EF.DG 16 contain personal data of the MRTD holder. The Chip Authentication Public Key (EF.DG 14) is used by the inspection system for the Chip Authentication. The EF.SOD is used by the inspection system for Passive Authentication of the logical MRTD. Due to interoperability reasons as the ‘ICAO Doc 9303’ [13] the TOE described in this security target specifies only the BAC mechanisms with resistance against enhanced basic attack potential granting access to • Logical MRTD standard User Data (i.e. Personal Data) of the MRTD holder (EF.DG1, • EF.DG2, EF.DG5 to EF.DG13, EF.DG16), • Chip Authentication Public Key in EF.DG14, • Active Authentication Public Key in EF.DG15, • Document Security Object (SOD) in EF.SOD, • Common data in EF.COM. The TOE prevents read access to sensitive User Data • Sensitive biometric reference data (EF.DG3, EF.DG4) . A sensitive asset is the following more general one. Authenticity of the MRTD’s chip The authenticity of the MRTD’s chip personalized by the issuing State or Organization for the MRTD holder is used by the traveller to prove his possession of a genuine MRTD. 3.2. Subjects This security target considers the following subjects: Manufacturer The generic term for the IC Manufacturer producing the integrated circuit and the MRTD Manufacturer completing the IC to the MRTD’s chip. The Manufacturer is the default user of the TOE during the Phase 2 Manufacturing. The TOE does not distinguish between the user’s IC Manufacturer and MRTD Manufacturer using this role Manufacturer. The Manufacturer of the chip is the NXP company. The ID&Trust IDentity Applet Suite v3.4 is located on the card. Personalization Agent The agent is acting on behalf of the issuing State or Organization to personalize the MRTD for the holder by some or all of the following activities: IDentity Applet v.3.4/BAC/AA Security Target Page 30 of 96 (i) establishing the identity, the holder for the biographic data in the MRTD, (ii) enrolling the biometric reference data of the MRTD holder i.e. the portrait, the encoded finger image(s) and/or the encoded iris image(s) (iii) writing these data on the physical and logical MRTD for the holder as defined for global, international and national interoperability, (iv) writing the initial TSF data and (v) signing the Document Security Object defined in [13]. Currently Application Profile Provider is ID&Trust. Terminal A terminal is any technical system communicating with the TOE through the contactless interface. Inspection system (IS) A technical system used by the border control officer of the receiving State (i) examining an MRTD presented by the traveler and verifying its authenticity and (i) verifying the traveler as MRTD holder. The Basic Inspection System (BIS): (i) contains a terminal for the contactless communication with the MRTD’s chip, (ii) implements the terminals part of the Basic Access Control Mechanism and (iii) gets the authorization to read the logical MRTD under the Basic Access Control by optical reading the MRTD or other parts of the passport book providing this information. The General Inspection System (GIS) is a Basic Inspection System which implements additionally the Chip Authentication Mechanism. The Extended Inspection System (EIS) in addition to the General Inspection System: (i) implements the Terminal Authentication Protocol and (ii) is authorized by the issuing State or Organization through the Document Verifier of the receiving State to read the sensitive biometric reference data. The security attributes of the EIS are defined of the Inspection System Certificates. Application note 11 (modified by ST author, taken from application note 6 from [18]) This security target does not distinguish between the BIS, GIS and EIS because the Extended Access Control is outside the scope. MRTD Holder The rightful holder of the MRTD for whom the issuing State or Organization personalized the MRTD. Traveler Person presenting the MRTD to the inspection system and claiming the identity of the MRTD holder. Attacker A threat agent trying IDentity Applet v.3.4/BAC/AA Security Target Page 31 of 96 (i) to identify and to trace the movement of the MRTD’s chip remotely (i.e. without knowing or optically reading the printed MRZ data), (ii) to read or to manipulate the logical MRTD without authorization, or (iii) to forge a genuine MRTD. Application note 12 (taken from application note 7 from [18]) An impostor is attacking the inspection system as TOE IT environment independent on using a genuine, counterfeit or forged MRTD. Therefore, the impostor may use results of successful attacks against the TOE but the attack itself is not relevant for the TOE. 3.3. Assumptions The assumptions describe the security aspects of the environment in which the TOE will be used or is intended to be used. A.MRTD_Manufact MRTD manufacturing on steps 4 to 6 It is assumed that appropriate functionality testing of the MRTD is used. It is assumed that security procedures are used during all manufacturing and test operations to maintain confidentiality and integrity of the MRTD and of its manufacturing and test data (to prevent any possible copy, modification, retention, theft or unauthorized use). A.MRTD_Delivery MRTD delivery during steps 4 to 6 Procedures shall guarantee the control of the TOE delivery and storage process and conformance to its objectives: • Procedures shall ensure protection of TOE material/information under delivery and storage. • Procedures shall ensure that corrective actions are taken in case of improper operation in the delivery process and storage. • Procedures shall ensure that people dealing with the procedure for delivery have got the required skill. Application note 13 (of the ST Author) The delivery procedures between ID&Trust (applet developer) and the manufacturer: 1. The IDentity Applet Developer develops a new version of the ID&Trust IDentity Applet v3.4/BAC. 2. After the new version is tested a new release is issued and stored in configuration management system. 3. The new version of the IDentity Applet v3.4 is sent to as required by [27]. A.Pers_Agent Personalization of the MRTD’s chip The Personalization Agent ensures the correctness of: (i) the logical MRTD with respect to the MRTD holder, (ii) the Document Basic Access Keys, IDentity Applet v.3.4/BAC/AA Security Target Page 32 of 96 (iii) the Chip Authentication Public Key (EF.DG14) if stored on the MRTD’s chip, and (iv) the Document Signer Public Key Certificate (if stored on the MRTD’s chip). The Personalization Agent signs the Document Security Object. The Personalization Agent bears the Personalization Agent Authentication to authenticate himself to the TOE by symmetric cryptographic mechanisms. PERSONALIZED state of the IDentity Appletv3.4/BAC indicates that the IDentity Appletv3.4/BAC is in the Operational Phase. In this phase the corresponding standard and documented behaviour is followed. In Operational phase access control for eID functions and data objects are activated and managed according to the pre-defined security attributes and security environments. A.Insp_Sys Inspection Systems for global interoperability The Inspection System is used by the border control officer of the receiving State: (i) examining an MRTD presented by the traveller and verifying its authenticity and (ii) verifying the traveller as MRTD holder. The Basic Inspection System for global interoperability: (i) includes the Country Signing Public Key and the Document Signer Public Key of each issuing State or Organization, and (ii) implements the terminal part of the Basic Access Control [13]. The Basic Inspection System reads the logical MRTD under Basic Access Control and performs the Passive Authentication to verify the logical MRTD. Application note 14 (taken from application note 8 from [18]) According to [13] the support of the Passive Authentication mechanism is mandatory whereas the Basic Access Control is optional. This ST does not address Primary Inspection Systems therefore the BAC is mandatory within this ST. Application note 15 (from ST author) In addition, the A.Insp_Sys contains that in case the Basic Inspection System supports the Active Authentication the Basic Inspection System implements the terminal part of Active Authentication (defined in [13]). A.BAC-Keys Cryptographic quality of Basic Access Control Keys The Document Basic Access Control Keys being generated and imported by the issuing State or Organization have to provide sufficient cryptographic strength. As a consequence of the ‘ICAO Doc 9303’ [13], the Document Basic Access Control Keys are derived from a defined subset of the individual printed MRZ data. It has to be ensured that these data provide sufficient entropy to withstand any attack based on the decision that the inspection system has to derive Document Access Keys from the printed MRZ data with enhanced basic attack potential. Application note 16 (taken from application note 9 from [18]) IDentity Applet v.3.4/BAC/AA Security Target Page 33 of 96 When assessing the MRZ data resp. the BAC keys entropy potential dependencies between these data (especially single items of the MRZ) have to be considered and taken into account. E.g. there might be a direct dependency between the Document Number when chosen consecutively and the issuing date. The ST contains another Assumption, not defined in the PP, justified by the fact that the TOE is divided to two parts. The TOE Part I according to 1.4.2 is developed by NXP at the NXP sites, which are already certified at the EAL6+ assurance level. 3.4. 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 be low. T.Chip_ID Identification of MRTD’s chip Adverse action: An attacker trying to trace the movement of the MRTD by identifying remotely the MRTD’s chip by establishing or listening to communications through the contactless communication interface. Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance Asset: Anonymity of user T.Skimming Skimming the logical MRTD Adverse action: An attacker imitates an inspection system trying to establish a communication to read the logical MRTD or parts of it via the contactless communication channel of the TOE. Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance Asset: confidentiality of logical MRTD data T.Eavesdropping Eavesdropping to the communication between TOE and inspection system Adverse action: An attacker is listening to an existing communication between the MRTD’s chip and an inspection system to gain the logical MRTD or parts of it. The inspection system uses the MRZ data printed on the MRTD data page, but the attacker does not know these data in advance. Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance Asset: confidentiality of logical MRTD data T.Forgery Forgery of data on MRTD’s chip IDentity Applet v.3.4/BAC/AA Security Target Page 34 of 96 Adverse action: An attacker alters fraudulently the complete stored logical MRTD or any part of it including its security related data in order to deceive on an inspection system by means of the changed MRTD holder’s identity or biometric reference data. This threat comprises several attack scenarios of MRTD forgery. The attacker may alter the biographical data on the biographical data page of the passport book, in the printed MRZ and in the digital MRZ to claim another identity of the traveler. The attacker may alter the printed portrait and the digitized portrait to overcome the visual inspection of the inspection officer and the automated biometric authentication mechanism by face recognition. The attacker may alter the biometric reference data to defeat automated biometric authentication mechanism of the inspection system. The attacker may combine data groups of different logical MRTDs to create a new forged MRTD, e.g. the attacker writes the digitized portrait and optional biometric reference finger data read from the logical MRTD of a traveler into another MRTD’s chip leaving their digital MRZ unchanged to claim the identity of the holder this MRTD. The attacker may also copy the complete unchanged logical MRTD to another contactless chip. Threat agent: having enhanced basic attack potential, being in possession of one or more legitimate MRTDs Asset: authenticity of logical MRTD data The TOE shall avert the threats as specified below. T.Abuse-Func Abuse of Functionality Adverse action: An attacker may use functions of the TOE which shall not be used in the phase “Operational Use” in order (i) to manipulate User Data, (ii) to manipulate (explore, bypass, deactivate or change) security features or functions of the TOE or (iii) to disclose or to manipulate TSF Data. This threat addresses the misuse of the functions for the initialization and the personalization in the operational state after delivery to MRTD holder. Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF T.Information_Leakage Information Leakage from MRTD’s chip Adverse action: An attacker may exploit information which is leaked from the TOE during its usage in order to disclose confidential TSF data. The information leakage may be inherent in the normal operation or caused by the attacker. 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 still available even for a contactless chip) and can then be related to the specific IDentity Applet v.3.4/BAC/AA Security Target Page 35 of 96 operation being performed. Examples are the Differential Electromagnetic Analysis (DEMA) and the Differential Power Analysis (DPA). Moreover, the attacker may try actively to enforce information leakage by fault injection (e.g. Differential Fault Analysis). Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD Asset: confidentiality of logical MRTD and TSF data T.Phys-Tamper Physical Tampering Adverse action: An attacker may perform physical probing of the MRTD’s chip in order (i) to disclose TSF Data or (ii) to disclose/reconstruct the MRTD’s chip Embedded Software. An attacker may physically modify the MRTD’s chip in order to (i) modify security features or functions of the MRTD’s chip, (ii) modify security functions of the MRTD’s chip Embedded Software, (iii) modify User Data or (iv) to modify TSF data. The physical tampering may be focused directly on the disclosure or manipulation of TOE User Data (e.g. the biometric reference data for the inspection system) or TSF Data (e.g. authentication key of the MRTD’s chip) or indirectly by preparation of the TOE to following attack methods by modification of security features (e.g. to enable information leakage through power analysis). Physical tampering requires direct interaction with the MRTD’s chip internals. Techniques commonly employed in IC failure analysis and IC reverse engineering efforts may be used. Before that, the hardware security mechanisms and layout characteristics need to be identified. Determination of software design including treatment of User Data and 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. Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF T.Malfunction Malfunction due to Environmental Stress Adverse action: An attacker may cause a malfunction of TSF or of the MRTD’s chip Embedded Software by applying environmental stress in order to (i) deactivate or modify security features or functions of the TOE or (ii) circumvent, deactivate or modify security functions of the MRTD’s chip Embedded Software. This may be achieved e.g. by operating the MRTD’s chip outside the normal operating conditions, exploiting errors in the MRTD’s chip Embedded Software or misusing administration function. To exploit these vulnerabilities an attacker needs information about the functional operation. Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF IDentity Applet v.3.4/BAC/AA Security Target Page 36 of 96 T.Counterfeit Counterfeit of travel document chip data Adverse action: An attacker with high attack potential produces an unauthorized copy or reproduction of a genuine travel document’s chip to be used as part of a counterfeit travel document. This violates the authenticity of the travel document’s chip used for authentication of a traveler by possession of a travel document The attacker may generate a new data set or extract completely or partially the data from a genuine travel document’s chip and copy them to another appropriate chip to imitate this genuine travel document’s chip. Threat agent: having high attack potential, being possession of one or more legitimate travel documents Asset: authenticity of logical MRTD 3.5. Organizational Security Policies The TOE shall comply with the following Organizational Security Policies (OSP) as security rules, procedures, practices, or guidelines imposed by an organization upon its operations (see CC part 1, sec. A.6). P.Manufact Manufacturing of the MRTD’s chip The Initialization Data are written by the IC Manufacturer to identify the IC uniquely. The MRTD Manufacturer writes the Pre-personalization Data which contains at least the Personalization Agent Key. P.Personalization Personalization of the MRTD 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 MRTD with respect to the MRTD holder. The personalization of the MRTD for the holder is performed by an agent authorized by the issuing State or Organization only. P.Personal_Data Personal data protection policy The biographical data and their summary printed in the MRZ and stored on the MRTD’s chip (EF.DG1), the printed portrait and the digitized portrait (EF.DG2), the biometric reference data of finger(s) (EF.DG3), the biometric reference data of iris image(s) (EF.DG4) and data according to LDS (EF.DG5 to EF.DG13, EF.DG16) stored on the MRTD’s chip are personal data of the MRTD holder. These data groups are intended to be used only with agreement of the MRTD holder by inspection systems to which the MRTD is presented. The MRTD’s chip shall provide the possibility for the Basic Access Control to allow read access to these data only for terminals successfully authenticated based on knowledge of the Document Basic Access Keys as defined in [13]. Application note 17 (taken from application note 10 from [18]) IDentity Applet v.3.4/BAC/AA Security Target Page 37 of 96 The organizational security policy P.Personal_Data is drawn from the ICAO ‘ICAO Doc 9303’ [13]. Note that the Document Basic Access Key is defined by the TOE environment and loaded to the TOE by the Personalization Agent. IDentity Applet v.3.4/BAC/AA Security Target Page 38 of 96 4. 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. OT.AC_Pers Access Control for Personalization of logical MRTD The TOE must ensure that the logical MRTD data in EF.DG1 to EF.DG16, the Document security object according to LDS [13] and the TSF data can be written by authorized Personalization Agents only. The logical MRTD data in EF.DG1 to EF.DG16 and the TSF data may be written only during and cannot be changed after its personalization. The Document security object can be updated by authorized Personalization Agents if data in the data groups EF.DG 3 to EF.DG16 are added. Application note 18 (taken from application note 11 from [18]) The OT.AC_Pers implies that: (1) the data of the LDS groups written during personalization for MRTD holder (at least EF.DG1 and EF.DG2) cannot be changed by write access after personalization, (2) the Personalization Agents may (a) add (fill) data into the LDS data groups not written yet, and (b) update and sign the Document Security Object accordingly. The support for adding data in the “Operational Use” phase is optional. OT.Data_Int Integrity of personal data The TOE must ensure the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. The TOE must ensure that the inspection system is able to detect any modification of the transmitted logical MRTD data. OT.Data_Conf Confidentiality of personal data The TOE must ensure the confidentiality of the logical MRTD data groups EF.DG1 to EF.DG16. Read access to EF.DG1 to EF.DG16 is granted to terminals successfully authenticated as Personalization Agent. Read access to EF.DG1, EF.DG2 and EF.DG5 to EF.DG16 is granted to terminals successfully authenticated as Basic Inspection System. The Basic Inspection System shall authenticate itself by means of the Basic Access Control based on knowledge of the Document Basic Access Key. The TOE must ensure the confidentiality of the logical MRTD data during their transmission to the Basic Inspection System. Application note 19 (taken from application note 12 from [18]) IDentity Applet v.3.4/BAC/AA Security Target Page 39 of 96 The traveler grants the authorization for reading the personal data in EF.DG1, EF.DG2 and EF.DG5 to EF.DG16 to the inspection system by presenting the MRTD. The MRTD’s chip shall provide read access to these data for terminals successfully authenticated by means of the Basic Access Control based on knowledge of the Document Basic Access Keys. The security objective OT.Data_Conf requires the TOE to ensure the strength of the security function Basic Access Control Authentication. The Document Basic Access Keys are derived from the MRZ data defined by the TOE environment and are loaded into the TOE by the Personalization Agent. Therefore, the sufficient quality of these keys has to result from the MRZ data’s entropy. Any attack based on decision of the ‘ICAO Doc 9303’ [13] that the inspection system derives Document Basic Access is ensured by OE.BAC- Keys. Note that the authorization for reading the biometric data in EF.DG3 and EF.DG4 is only granted after successful Enhanced Access Control not covered by this security target. Thus, the read access must be prevented even in case of a successful BAC Authentication. OT.Identification Identification and Authentication of the TOE The TOE must provide means to store IC Identification and Pre-Personalization Data in its non-volatile memory. The IC Identification Data must provide a unique identification of the IC during Phase 2 “Manufacturing” and Phase 3 “Personalization of the MRTD”. The storage of the Pre- Personalization data includes writing of the Personalization Agent Key(s). In Phase 4 “Operational Use” the TOE shall identify itself only to a successful authenticated Basic Inspection System or Personalization Agent. Application note 20 (taken from application note 13 from [18]) The TOE security objective OT.Identification addresses security features of the TOE to support the life cycle security in the manufacturing and personalization phases. The IC Identification Data are used for TOE identification in Phase 2 “Manufacturing” and for traceability and/or to secure shipment of the TOE from Phase 2 “Manufacturing” into the Phase 3 “Personalization of the MRTD”. The OT.Identification addresses security features of the TOE to be used by the TOE manufacturing. In the Phase 4 “Operational Use” the TOE is identified by the Document Number as part of the printed and digital MRZ. The OT.Identification forbids the output of any other IC (e.g. integrated circuit card serial number ICCSN) or MRTD identifier through the contactless interface before successful authentication as Basic Inspection System or as Personalization Agent. The following TOE security objectives address the protection provided by the MRTD’s chip independent of the TOE environment. OT.Prot_Abuse-Func Protection against Abuse of Functionality After delivery of the TOE to the MRTD Holder, the TOE must prevent the abuse of test and support functions that may be maliciously used to (i) disclose critical User Data, (ii) manipulate critical User Data of the IC Embedded Software, (iii) manipulate Soft-coded IC Embedded Software or IDentity Applet v.3.4/BAC/AA Security Target Page 40 of 96 (iv) bypass, deactivate, change or explore security features or functions of the TOE. Details of the relevant attack scenarios depend, for instance, on the capabilities of the Test Features provided by the IC Dedicated Test Software which are not specified here. OT.Prot_Inf_Leak Protection against Information Leakage The TOE must provide protection against disclosure of confidential TSF data stored and/or processed in the MRTD’s chip (i) 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 and (ii) by forcing a malfunction of the TOE and/or (iii) by a physical manipulation of the TOE. Application note 21 (taken from application note 14 from [18]) This objective pertains to measurements with subsequent complex signal processing due to normal operation of the TOE or operations enforced by an attacker. Details correspond to an analysis of attack scenarios which is not given here. 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 MRTD’s chip Embedded Software. This includes protection against attacks with enhanced-basic attack potential by means of (i) measuring through galvanic contacts which is direct physical probing on the chips surface except on pads being bonded (using standard tools for measuring voltage and current) or (ii) 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) (iii) manipulation of the hardware and its security features, as well as (iv) controlled manipulation of memory contents (User Data, TSF Data) with a prior (v) reverse-engineering to understand the design and its properties and functions. 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 has not been proven or tested. This is to prevent errors. The environmental conditions may include external energy (esp. electromagnetic) fields, voltage (on any contacts), clock frequency, or temperature. Application note 22 (taken from application note 15 from [18]) IDentity Applet v.3.4/BAC/AA Security Target Page 41 of 96 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 objective OT.Prot_Phys-Tamper) provided that detailed knowledge about the TOE´s internals. The following Security Objective for the TOE is defined in addition to the objectives given by the [17] to cover the Active Authentication mechanism. OT.Active_Auth_Proof Proof of travel document’s chip authenticity The TOE shall support the Basic Inspection Systems to verify the identity and authenticity of the travel document’s chip as issued by the identified issuing State or Organisation by means of the Active Authentication as defined in [13]. The authenticity proof provided by travel document’s chip shall be protected against attacks with high attack potential. 4.2. Security Objectives for the Operational Environment 4.2.1. Issuing State or Organization The issuing State or Organization will implement the following security objectives of the TOE environment. OE.MRTD_Manufact Protection of the MRTD Manufacturing Appropriate functionality testing of the TOE shall be used in step 4 to 6. During all manufacturing and test operations, security procedures shall be used through phases 4, 5 and 6 to maintain confidentiality and integrity of the TOE and its manufacturing and test data. OE.MRTD_Delivery Protection of the MRTD delivery Procedures shall ensure protection of TOE material/information under delivery including the following objectives: i. non-disclosure of any security relevant information, ii. identification of the element under delivery, iii. meet confidentiality rules (confidentiality level, transmittal form, reception acknowledgment), iv. physical protection to prevent external damage, v. secure storage and handling procedures (including rejected TOE’s), vi. traceability of TOE during delivery including the following parameters: a. origin and shipment details, b. reception, reception acknowledgement, c. location material/information. Procedures shall ensure that corrective actions are taken in case of improper operation in the delivery process (including if applicable any non-conformance to the confidentiality convention) and highlight all non-conformance to this process. IDentity Applet v.3.4/BAC/AA Security Target Page 42 of 96 Procedures shall ensure that people (shipping department, carrier, reception department) dealing with the procedure for delivery have got the required skill, training and knowledge to meet the procedure requirements and be able to act fully in accordance with the above expectations. OE.Personalization Personalization of logical MRTD The issuing State or Organization must ensure that the Personalization Agents acting on behalf of the issuing State or Organization i. establish the correct identity of the holder and create biographical data for the MRTD, ii. enroll the biometric reference data of the MRTD holder i.e. the portrait, the encoded finger image(s) and/or the encoded iris image(s) and iii. personalize the MRTD for the holder together with the defined physical and logical security measures to protect the confidentiality and integrity of these data. OE.Pass_Auth_Sign Authentication of logical MRTD by Signature The issuing State or Organization must i. generate a cryptographic secure Country Signing CA Key Pair, ii. ensure the secrecy of the Country Signing CA Private Key and sign Document Signer Certificates in a secure operational environment, and iii. distribute the Certificate of the Country Signing CA Public Key to receiving States and Organizations maintaining its authenticity and integrity. The issuing State or Organization must i. generate a cryptographic secure Document Signer Key Pair and ensure the secrecy of the Document Signer Private Keys, ii. sign Document Security Objects of genuine MRTD in a secure operational environment only and iii. distribute the Certificate of the Document Signer Public Key to receiving States and Organizations. The digital signature in the Document Security Object relates all data in the data in EF.DG1 to EF.DG16 if stored in the LDS according to [13]. OE.BAC-Keys Cryptographic quality of Basic Access Control Keys The Document Basic Access Control Keys being generated and imported by the issuing State or Organization have to provide sufficient cryptographic strength. As a consequence of the ‘ICAO Doc 9303’ [13] the Document Basic Access Control Keys are derived from a defined subset of the individual printed MRZ data. It has to be ensured that these data provide sufficient entropy to withstand any attack based on the decision that the inspection system has to derive Document Basic Access Keys from the printed MRZ data with enhanced basic attack potential. 4.2.2. Receiving State or Organization The receiving State or Organization will implement the following security objectives of the TOE environment. IDentity Applet v.3.4/BAC/AA Security Target Page 43 of 96 OE.Exam_MRTD Examination of the MRTD passport book The inspection system of the receiving State or Organization must examine the MRTD presented by the traveler to verify its authenticity by means of the physical security measures and to detect any manipulation of the physical MRTD. The Basic Inspection System for global interoperability i. includes the Country Signing Public Key and the Document Signer Public Key of each issuing State or Organization, and ii. implements the terminal part of the Basic Access Control [13]. OE.Passive_Auth_Verify Verification by Passive Authentication The border control officer of the receiving State uses the inspection system to verify the traveler as MRTD holder. The inspection systems must have successfully verified the signature of Document Security Objects and the integrity data elements of the logical MRTD before they are used. The receiving States and Organizations must manage the Country Signing Public Key and the Document Signer Public Key maintaining their authenticity and availability in all inspection systems. OE.Prot_Logical_MRTD Protection of data from the logical MRTD The inspection system of the receiving State or Organization ensures the confidentiality and integrity of the data read from the logical MRTD. The receiving State examining the logical MRTD being under Basic Access Control will use inspection systems which implement the terminal part of the Basic Access Control and use the secure messaging with fresh generated keys for the protection of the transmitted data (i.e. Basic Inspection Systems). OE.Active_Auth_Key_Travel_Document Travel document Active Authentication Key The issuing State or Organisation has to establish the necessary public key infrastructure in order to i. generate the travel document’s Active Authentication Key Pair if necessary, 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 travel document’s chip used for genuine travel document by proof the authenticity of the active authentication public key by Passive Authentication. 4.3.

The OSP P.Personalization “Personalization of the MRTD by issuing State or Organization only” addresses the (i) the enrolment of the logical MRTD by the Personalization Agent as described in the security objective for the TOE environment OE.Personalization “Personalization of logical MRTD”, 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 MRTD”. Note the manufacturer equips the TOE with the Personalization Agent 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 management of TSF to the Personalization Agent. The OSP P.Personal_Data “Personal data protection policy” requires the TOE (i) to support the protection of the confidentiality of the logical MRTD by means of the Basic Access Control and (ii) enforce the access control for reading as decided by the issuing State or Organization. This policy is implemented by the IDentity Applet v.3.4/BAC/AA Security Target Page 45 of 96 security objectives OT.Data_Int “Integrity of personal data” describing the unconditional protection of the integrity of the stored data and during transmission. The security objective OT.Data_Conf “Confidentiality of personal data” describes the protection of the confidentiality. The threat T.Chip_ID “Identification of MRTD’s chip” addresses the trace of the MRTD movement by identifying remotely the MRTD’s chip through the contactless communication interface. This threat is countered as described by the security objective OT.Identification by Basic Access Control using sufficiently strong derived keys as required by the security objective for the environment OE.BAC-Keys. The threat T.Skimming “Skimming digital MRZ data or the digital portrait” and T.Eavesdropping “Eavesdropping to the communication between TOE and inspection system” address the reading of the logical MRTD trough the contactless interface or listening the communication between the MRTD’s chip and a terminal. This threat is countered by the security objective OT.Data_Conf “Confidentiality of personal data” through Basic Access Control using sufficiently strong derived keys as required by the security objective for the environment OE.BAC-Keys. The threat T.Forgery “Forgery of data on MRTD’s chip” addresses the fraudulent alteration of the complete stored logical MRTD or any part of it. The security objective OT.AC_Pers “Access Control for Personalization of logical MRTD“ requires the TOE to limit the write access for the logical MRTD to the trustworthy Personalization Agent (cf. OE.Personalization). The TOE will protect the integrity of the stored logical MRTD according the security objective OT.Data_Int “Integrity of personal data” and OT.Prot_Phys-Tamper “Protection against Physical Tampering”. The examination of the presented MRTD passport book according to OE.Exam_MRTD “Examination of the MRTD passport book” shall ensure that passport book does not contain a sensitive contactless chip which may present the complete unchanged logical MRTD. The TOE environment will detect partly forged logical MRTD data by means of digital signature which will be created according to OE.Pass_Auth_Sign “Authentication of logical MRTD by Signature” and verified by the inspection system according to OE.Passive_Auth_Verif “Verification by Passive Authentication”. The threat T.Abuse-Func “Abuse of Functionality” addresses attacks using the MRTD’s chip as production material for the MRTD and misuse of the functions for personalization in the operational state after delivery to MRTD holder to disclose or to manipulate the logical MRTD. This threat is countered by OT.Prot_Abuse-Func “Protection against Abuse of Functionality”. Additionally this objective is supported by the security objective for the TOE environment: OE.Personalization “Personalization of logical MRTD” ensuring that the TOE security functions for the initialization and the personalization are disabled and the security functions for the operational state after delivery to MRTD holder are enabled according to the intended use of the TOE. The threats T.Information_Leakage “Information Leakage from MRTD’s chip”, T.Phys-Tamper “Physical Tampering” and T.Malfunction “Malfunction due to Environmental Stress” are typical for integrated circuits like smart cards under direct attack with high attack potential. The protection of the TOE against these threats is addressed by the directly related security objectives OT.Prot_Inf_Leak “Protection against Information Leakage”, OT.Prot_Phys-Tamper “Protection against Physical Tampering” and OT.Prot_Malfunction “Protection against Malfunctions”. The threat T.Counterfeit “Counterfeit of travel document’s chip data” is thwarted through the chip by an identification and authenticity proof required by OT.Active_Auth_Proof “Proof of travel document’s chip authentication” using an authentication key pair to be generated by the issuing state or organisation. The IDentity Applet v.3.4/BAC/AA Security Target Page 46 of 96 Active Authentication public key has to be written into EF.DG15 and signed by means of Documents Security Objects as demanded by OE.Active_Auth_Key_Travel_Document “Travel Document Active Authentication Key”. The assumption A.MRTD_Manufact “MRTD manufacturing on step 4 to 6” is covered by the security objective for the TOE environment OE.MRTD_Manufact “Protection of the MRTD Manufacturing” that requires to use security procedures during all manufacturing steps. The assumption A.MRTD_Delivery “MRTD delivery during step 4 to 6” is covered by the security objective for the TOE environment OE.MRTD_Delivery. “Protection of the MRTD delivery” that requires to use security procedures during delivery steps of the MRTD. The assumption A.Pers_Agent “Personalization of the MRTD’s chip” is covered by the security objective for the TOE environment OE.Personalization “Personalization of logical MRTD” including the enrolment, the protection with digital signature and the storage of the MRTD holder personal data. The examination of the MRTD passport book addressed by the assumption A.Insp_Sys “Inspection Systems for global interoperability” is covered by the security objectives for the TOE environment OE.Exam_MRTD “Examination of the MRTD passport book”. The security objectives for the TOE environment OE.Prot_Logical_MRTD “Protection of data from the logical MRTD” will require the Basic Inspection System to implement the Basic Access Control and to protect the logical MRTD data during the transmission and the internal handling. The assumption A.BAC-Keys “Cryptographic quality of Basic Access Control Keys” is directly covered by the security objective for the TOE environment OE.BAC-Keys “Cryptographic quality of Basic Access Control Keys” ensuring the sufficient key quality to be provided by the issuing State or Organization.

Extended Components Definition This security target uses components defined as extensions to [2], which are defined in the relevant PP- 0055 [17] protection profile. The FIA_API family taken from [18] because of the optional functionality of the TOE (Active Authentication). 5.1. Definition of the Family FIA_API To describe the IT security functional requirements of the TOE a sensitive family (FIA_API) of the Class FIA (Identification and authentication) is defined here. 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. FIA_API Authentication Proof of Identity Family behavior: 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: FIA_API.1 The following actions could be considered for the management functions in FMT: Management of authentication information used to prove the claimed identity.

Definition of the Family FAU_SAS To define the security functional requirements of the TOE a sensitive 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. FAU_API Authentication Proof of Identity 1 IDentity Applet v.3.4/BAC/AA Security Target Page 48 of 96 The family “Audit data storage (FAU_SAS)” is specified as follows. FAU_SAS Audit data storage Family behavior: 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: FAU_SAS.1 There are no management activities foreseen. Audit: FAU_SAS.1 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. 5.3. Definition of the Family FCS_RND To define the IT security functional requirements of the TOE a sensitive family (FCS_RND) of the Class FCS (cryptographic support) is defined here. This family describes the functional requirements for random number generation used for cryptographic purposes. The component FCS_RND 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. 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 leveling: FAU_SAS Audit data storage 1 FCS_RND Generation of random numberts 1 IDentity Applet v.3.4/BAC/AA Security Target Page 49 of 96 FCS_RND.1 Generation of random numbers requires that random numbers meet a defined quality metric.

Definition of the 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 the 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. 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. Component leveling: 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. 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 lifecycle. FMT_LIM Limited capabilities and availability 1 2 IDentity Applet v.3.4/BAC/AA Security Target Page 50 of 96 Management: FMT_LIM.1, FMT_LIM.2 There are no management activities foreseen. Audit: FMT_LIM.1, FMT_LIM.2 There are no actions defined to be auditable. To define the IT security functional requirements of the TOE a sensitive family (FMT_LIM) of the Class FMT (Security Management) is defined here. This family 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 the abuse of functions by limiting the capabilities of the functions and by limiting their availability. The TOE Functional Requirement “Limited capabilities (FMT_LIM.1)” is specified as follows. 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].

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 23 (taken from application note 16 from [18]) 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 i. 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 IDentity Applet v.3.4/BAC/AA Security Target Page 51 of 96 ii. the TSF is designed with test and support functionality that is removed from, or disabled in, the product prior to the Operational Use Phase. The combination of both requirements shall enforce the policy. 5.5. Definition of the Family FPT_EMS Application note 24 (from ST author) The [17] use the FPT_EMSEC, but according to [2] 7.1.2.1: “The categorical information consists of a short name of seven characters, with the first three identical to the short name of the class followed by an underscore and the short name of the family as follows XXX_YYY.” In order to fulfil the referenced CC requirement, in current ST FPT_EMS will be applied. The content of the FPT_EMSEC is not modified. The sensitive 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 the TOE and other secret data 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 which are not directly addressed by any other component of CC part 2 [2]. The family “TOE Emanation (FPT_EMS)” is specified as follows. FMT_EMS TOE emanation Family behavior This family defines requirements to mitigate intelligible emanations. Component leveling: 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: FPT_EMS.1 There are no management activities foreseen.

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 access to [assignment: list of types of TSF data] and [assignment: list of types of user data]. IDentity Applet v.3.4/BAC/AA Security Target Page 53 of 96 6. Security 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 [1] of the CC. Each of these operations is used in this ST 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 and the original text of the component is given by a footnote. Selections to be filled in by the ST author appear in square brackets with an indication that a selection is to be made, [selection:], and are italicized. Selections filled in by the ST author are denoted as double underlined text and a foot note where the selection choices from the PP are listed. 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 by showing as underlined text and the original text of the component is given by a footnote. Assignments to be filled in by the ST author appear in square brackets with an indication that an assignment is to be made [assignment:] and are italicized. In some cases, the assignment made by the PP authors defines a selection to be performed by the ST author. Thus, this text is underlined and italicized like this. Assignments filled in by the ST author are denoted as double underlined text. 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”, “Basic Inspection System” and “Terminal” used in the following chapter is given in section 3.2. Note, that all these subjects are acting for homonymous external entities. All used objects are defined in section 8. The operations “write”, “read”, “modify”, and “disable read access” are used in accordance with the general linguistic usage. The operations “transmit”, “receive” and “authenticate” are originally taken from [2]. Security Attribute Values Meaning Terminal authentication status none (any Terminal) default role (i.e. without authorisation after start-up) Basic Inspection System Terminal is authenticated as Basic Inspection System after successful Authentication in accordance with the definition in rule 2 of FIA_UAU.5.2. Personalisation Agent Terminal is authenticated as Personalisation Agent after successful Authentication in accordance with the definition in rule 1 of FIA_UAU.5.2. Table 7 Definition of security attributes IDentity Applet v.3.4/BAC/AA Security Target Page 54 of 96 The following objects are defined in addition to the objects to cover the Active Authentication mechanism: Name Data Active Authentication Key Pair The Active Authentication Key Pair (KPrAA, KPuAA) is used for the Active Authentication mechanism according to [13]. Active Authentication Public Key (KPuAA) The Active Authentication Public Key (KPuAA) is stored in the EF.DG15 Active Authentication Public Key of the TOE’s logical travel document and used by the inspection system for Active Authentication of the travel document’s chip. It is part of the user data provided by the TOE for the IT environment. A hash representation of DG15 (Public Key (KPuAA) info) is stored in the Document Security Object (SOD). Active Authentication Private Key (KPrAA) The Active Authentication Private Key (KPrAA) is used by the TOE to authenticate itself as authentic travel document’s chip. It is part of the TSF data.

Table 9 Used authentication mechanism The TOE shall meet the requirement “Timing of identification (FIA_UID.1)” as specified below (Common Criteria Part 2). FIA_UID.1 Timing of identification Hierarchical to: No other components. Dependencies: No dependencies. FIA_UID.1.1 The TSF shall allow 1. to read the Initialization Data in Phase 2 “Manufacturing”, 2. to read the random identifier in Phase 3 “Personalization of the MRTD”, 3. to read the random identifier in Phase 4 “Operational Use”41 40 [assignment: a defined quality metric] 41 [assignment: list of TSF-mediated actions] IDentity Applet v.3.4/BAC/AA Security Target Page 61 of 96 on behalf of the user to be performed before the user is identified. FIA_UID.1.2 The TSF shall require each user to be successfully identified before allowing any other TSF-mediated actions on behalf of that user. Application note 36 (taken from application note 26 from [18]) The IC manufacturer and the MRTD manufacturer write the Initialization Data and/or Pre-personalization Data in the audit records of the IC during the Phase 2 “Manufacturing”. The audit records can be written only in the Phase 2 Manufacturing of the TOE. At this time the Manufacturer is the only user role available for the TOE. The MRTD manufacturer may create the user role Personalization Agent for transition from Phase 2 to Phase 3 “Personalization of the MRTD”. The users in role Personalization Agent identify themselves by means of selecting the authentication key. After personalization in the Phase 3 (i.e. writing the digital MRZ and the Document Basic Access Keys) the user role Basic Inspection System is created by writing the Document Basic Access Keys. The Basic Inspection System is identified as default user after power up or reset of the TOE i.e. the TOE will use the Document Basic Access Key to authenticate the user as Basic Inspection System. Application note 37 (taken from application note 27 from [18]) In the “Operational Use” phase the MRTD must not allow anybody to read the Integrated Circuit Card Serial Number (ICCSN), the MRTD identifier or any other unique identification before the user is authenticated as Basic Inspection System (cf. T.Chip_ID). Note that the terminal and the MRTD’s chip use a (randomly chosen) identifier for the communication channel to allow the terminal to communicate with more than one RFID. If this identifier is randomly selected it will not violate the OT.Identification. The TOE shall meet the requirement “Timing of authentication (FIA_UAU.1)” as specified below (Common Criteria Part 2). FIA_UAU.1 Timing of authentication Hierarchical to: No other components. Dependencies: FIA_UID.1 Timing of identification. FIA_UAU.1.1 The TSF shall allow 4. 1. to read the Initialization Data in Phase 2 “Manufacturing”, 5. 2. to read the random identifier in Phase 3 “Personalization of the MRTD”, 6. 3. to read the random identifier in Phase 4 “Operational Use”42 on behalf of the user to be performed before the user is authenticated. FIA_UAU.1.2 42 [assignment: list of TSF-mediated actions] IDentity Applet v.3.4/BAC/AA Security Target Page 62 of 96 The TSF shall require each user to be successfully authenticated before allowing any other TSF-mediated actions on behalf of that user. Application note 38 (taken from application note 28 from [18]) The Basic Inspection System and the Personalization Agent authenticate themselves. The TOE shall meet the requirements of “Single-use authentication mechanisms (FIA_UAU.4)” as specified below (Common Criteria Part 2). FIA_UAU.4 Single-use authentication mechanisms - Single-use authentication of the Terminal by the TOE Hierarchical to: No other components. Dependencies: No dependencies. FIA_UAU.4.1 The TSF shall prevent reuse of authentication data related to 1. Basic Access Control Authentication Mechanism, 2. Authentication Mechanism based on Triple-DES or AES.43 ,44 . 3. Active Authentication according to [14] Application note 39 (taken from application note 29 from [18]) The authentication mechanisms may use either a challenge freshly and randomly generated by the TOE to prevent reuse of a response generated by a terminal in a successful authentication attempt. However, the authentication of Personalisation Agent may rely on other mechanisms ensuring protection against replay attacks, such as the use of an internal counter as a diversifier. Application note 40 (taken from application note 30 from [18]) The Basic Access Control Mechanism is a mutual device authentication mechanism defined in [13]. In the first step the terminal authenticates itself to the MRTD’s chip and the MRTD’s chip authenticates to the terminal in the second step. In this second step the MRTD’s chip provides the terminal with a challenge- response-pair which allows a unique identification of the MRTD’s chip with some probability depending on the entropy of the Document Basic Access Keys. Therefore, the TOE shall stop further communications if the terminal is not successfully authenticated in the first step of the protocol to fulfil the security objective OT.Identification and to prevent T.Chip_ID. The TOE shall meet the requirement “Multiple authentication mechanisms (FIA_UAU.5)” as specified below (Common Criteria Part 2). FIA_UAU.5 Multiple authentication mechanisms Hierarchical to: No other components. 43 [assignment: identified authentication mechanism(s)] 44 [selection: Triple-DES, AES or other approved algorithms] IDentity Applet v.3.4/BAC/AA Security Target Page 63 of 96 Dependencies: No dependencies. FIA_UAU.5.1 The TSF shall provide 1. Basic Access Control Authentication Mechanism 2. Symmetric Authentication Mechanism based on Triple-DES or AES,45 ,46 to support user authentication. FIA_UAU.5.2 The TSF shall authenticate any user’s claimed identity according to the following rules: 1. the TOE accepts the authentication attempt as Personalization Agent by one of the following mechanism(s): the Basic Access Control Mechanism with the Personalization Agent Key, the Symmetric Authentication Mechanism with the Personalization Agent Key,47 2. the TOE accepts the authentication attempt as Basic Inspection System only by means of the Basic Access Control Authentication Mechanism with the Document Basic Access Keys.48 Application note 41 (taken from application note 31 from [18]) In case the ‘Common Criteria Protection Profile Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE (EAC PP)’ [18]should also be fulfilled the Personalization Agent should not be authenticated by using the BAC or the symmetric authentication mechanism as they base on the two-key Triple-DES. The Personalization Agent could be authenticated by using the symmetric AES-based authentication mechanism or other (e.g. the Terminal Authentication Protocol using the Personalization Key, cf. [19] FIA_UAU.5.2). Application note 42 (taken from application note 32 from [18]) The Basic Access Control Mechanism includes the secure messaging for all commands exchanged after successful authentication of the inspection system. The Personalization Agent may use Symmetric Authentication Mechanism without secure messaging mechanism as well if the personalization environment prevents eavesdropping to the communication between TOE and personalization terminal. The Basic Inspection System may use the Basic Access Control Authentication Mechanism with the Document Basic Access Keys.

FIA_UAU.6.1 The TSF shall re-authenticate the user under the conditions each command sent to the TOE during a BAC mechanism based communication after successful authentication of the terminal with Basic Access Control Authentication Mechanism.49 Application note 43 (taken from application note 33 from [18]) The Basic Access Control Mechanism specified in [13] includes the secure messaging for all commands exchanged after successful authentication of the Inspection System. The TOE checks by secure messaging in MAC_ENC mode each command based on Retail-MAC whether it was sent by the successfully authenticated terminal (see FCS_COP.1/MAC for further details). The TOE does not execute any command with incorrect message authentication code. Therefore, the TOE re-authenticates the user for each received command and accepts only those commands received from the previously authenticated BAC user. Application note 44 (taken from application note 34 from [18]) Note that in case the TOE should also fulfil [18] the BAC communication might be followed by a Chip Authentication mechanism establishing a new secure messaging that is distinct from the BAC based communication. In this case the condition in FIA_UAU.6 above should not contradict to the option that commands are sent to the TOE that are no longer meeting the BAC communication but are protected by a more secure communication channel established after a more advanced authentication process. FIA_API.1/AA Authentication Proof of Identity – travel document Hierarchical to: No other components. Dependencies: No dependencies. FIA_API.1.1/AA The TSF shall provide the Active Authentication Mechanism according to [14]50 to prove the identity of the TOE.51 Application note 45 (from the ST author) The SFR FIA_API.1/AA has been included in this security target in addition to the SFRs defined by the [17] claimed in clause 2.2.

The Basic Inspection System is not allowed to read the data in EF.DG3 and EF.DG462. Application note 47 (taken from application note 36 from [18]) The inspection system needs special authentication and authorization for read access to DG3 and DG4 not defined in this security target (cf. [18] for details). Application note 48 (taken from application note 37 from [18]) FDP_UCT.1 and FDP_UIT.1 require the protection of the User Data transmitted from the TOE to the terminal by secure messaging with encryption and message authentication codes after successful authentication of the terminal. The authentication mechanisms as part of Basic Access Control Mechanism include the key agreement for the encryption and the message authentication key to be used for secure messaging. The TOE shall meet the requirement “Basic data exchange confidentiality (FDP_UCT.1)” as specified below (Common Criteria Part 2).

FDP_UIT.1.2 The TSF shall be able to determine on receipt of user data, whether modification, deletion, insertion and replay68 has occurred. 6.1.5. Class FMT Security Management Application note 49 (taken from application note 38 from [18]) The SFR FMT_SMF.1 and FMT_SMR.1 provide basic requirements to the management of the TSF data. The TOE shall meet the requirement “Specification of Management Functions (FMT_SMF.1)” as specified below (Common Criteria Part 2). FMT_SMF.1 Specification of Management Functions Hierarchical to: No other components.

The TOE shall meet the requirement “Security roles (FMT_SMR.1)” as specified below (Common Criteria Part 2). FMT_SMR.1 Security roles Hierarchical to: No other components Dependencies: FIA_UID.1 Timing of identification. FMT_SMR.1.1 The TSF shall maintain the roles 1. Manufacturer, 65 [assignment: access control SFP(s) and/or information flow control SFP(s)] 66 [selection: transmit, receive] 67 [selection: modification, deletion, insertion, replay] 68 [selection: modification, deletion, insertion, replay] 69 [assignment: list of management functions to be provided by the TSF] IDentity Applet v.3.4/BAC/AA Security Target Page 69 of 96 2. Personalization Agent, 3. Basic Inspection System70 FMT_SMR.1.2 The TSF shall be able to associate users with roles. Application note 50 (taken from application note 39 from [18]) The SFR FMT_LIM.1 and FMT_LIM.2 address the management of the TSF and TSF data to prevent misuse of test features of the TOE over the life cycle phases. The TOE shall meet the requirement “Limited capabilities (FMT_LIM.1)” as specified below (Common Criteria Part 2 extended). 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: 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 and 4. substantial information about construction of TSF to be gathered which may enable other attacks71 The TOE shall meet the requirement “Limited availability (FMT_LIM.2)” as specified below (Common Criteria Part 2 extended). 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: Deploying Test Features after TOE Delivery does not allow 70 [assignment: the authorised identified roles] 71 [assignment: Limited capability and availability policy] IDentity Applet v.3.4/BAC/AA Security Target Page 70 of 96 1. User Data to be disclosed or manipulated, 2. TSF data to be disclosed or manipulated 3. software to be reconstructed and 4. substantial information about construction of TSF to be gathered which may enable other attacks72 . Application note 51 (taken from application note 40 from [18]) 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 provide an optional approach to enforce the same policy. Note that the term “software” in item 3 of FMT_LIM.1.1 and FMT_LIM.2.1 refers to both IC Dedicated and IC Embedded Software. Application note 52 (taken from application note 41 from [18]) The following SFR 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 iterations address different management functions and different TSF data. FMT_MTD.1/INI_ENA Management of TSF data – Writing of Initialization Data and Pre-personalisation Data Hierarchical to: No other components. Dependencies: FMT_SMF.1 Specification of management functions FMT_SMR.1 Security roles FMT_MTD.1.1/INI_ENA The TSF shall restrict the ability to write73 the Initialization Data and Pre-personalisation Data74 to the Manufacturer75 . Application note 53 (taken from application note 42 from [18]) The pre-personalisation Data includes but is not limited to the authentication reference data for the Personalization Agent which is the symmetric cryptographic Personalization Agent Key.

Application note 54 (taken from application note 43 from [18]) According to P.Manufact the IC Manufacturer and the MRTD Manufacturer are the default users assumed by the TOE in the role Manufacturer during the Phase 2 “Manufacturing” but the TOE is not requested to distinguish between these users within the role Manufacturer. The TOE may restrict the ability to write the Initialization Data and the Pre-personalisation Data by (i) allowing to write these data only once and (ii) blocking the role Manufacturer at the end of the Phase 2. The IC Manufacturer may write the Initialization Data which includes but are not limited to the IC Identifier as required by FAU_SAS.1. The Initialization Data provides a unique identification of the IC which is used to trace the IC in the Phase 2 and 3 “personalisation” but is not needed and may be misused in the Phase 4 “Operational Use”. Therefore, the external read access shall be blocked. The MRTD Manufacturer will write the Pre-personalization Data.

This extension does not conflict with the strict conformance to the claimed [17]. 6.1.6. 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 82 [selection: change_default, query, modify, delete, clear, [assignment: other operations]] 83 [assignment: list of TSF data] 84 [assignment: list of TSF data] 85 [assignment: the authorised identified roles] 86 [selection: change_default, query, modify, delete, clear, [assignment: other operations]] 87 [assignment: list of TSF data] 88 [assignment: the authorised identified roles] IDentity Applet v.3.4/BAC/AA Security Target Page 73 of 96 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 functions. The TOE shall meet the requirement “TOE Emanation (FPT_EMS.1)” as specified below (Common Criteria Part 2 extended). FPT_EMS.1 TOE Emanation Hierarchical to: No other components. Dependencies: No Dependencies.

Application note 60 (taken from application note 47 from [18]) 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. Application note 61 (taken from application note 48 from [18]) The SFRs “Non-bypassability of the TSF FPT_RVM.1” and “TSF domain separation FPT_SEP.1” are no longer part of [2]. These requirements are now an implicit part of the assurance requirement ADV_ARC.1. 6.2. Security Assurance Requirements for the TOE The assurance requirements for the evaluation of the TOE and its development and operating environment are those taken from the Evaluation Assurance Level 4 (EAL4) and augmented by taking the following component: ALC_DVS.2. 6.3.

The write access to the logical MRTD data are defined by the SFR FDP_ACC.1 and FDP_ACF.1 as follows: only the successfully authenticated Personalization Agent is allowed to write the data of the groups EF.DG1 to EF.DG16 of the logical MRTD only once. The authentication of the terminal as Personalization Agent shall be performed by TSF according to SRF FIA_UAU.4 and FIA_UAU.5. The Personalization Agent can be authenticated either by using the BAC mechanism (FCS_CKM.1, FCS_COP.1/SHA, FCS_RND.1 (for key generation), and FCS_COP.1/ENC as well as FCS_COP.1/MAC) with the Personalization Agent Key or for reasons of interoperability with the [19] by using the symmetric authentication mechanism (FCS_COP.1/ AUTH). In case of using the BAC mechanism the SFR FIA_UAU.6 describes the re-authentication and FDP_UCT.1 and FDP_UIT.1 the protection of the transmitted data by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1, FCS_COP.1/SHA, FCS_RND.1 (for key generation), and FCS_COP.1/ENC as well as FCS_COP.1/MAC for the ENC_MAC_Mode. The SFR FMT_SMR.1 lists the roles (including Personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization) setting the Document Basic Access Keys according to the SFR FMT_MTD.1/KEY_WRITE as authentication reference data. The SFR FMT_MTD.1/KEY_READ prevents read access to the secret key of the Personalization Agent Keys and ensure together with the SFR FCS_CKM.4, FPT_EMS.1, FPT_FLS.1 and FPT_PHP.3 the confidentially of these keys. The security objective OT.Data_Int “Integrity of personal data” requires the TOE to protect the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. The write access to the logical MRTD data is defined by the SFR FDP_ACC.1 and FDP_ACF.1 in the same way: IDentity Applet v.3.4/BAC/AA Security Target Page 77 of 96 only the Personalization Agent is allowed to write the data of the groups EF.DG1 to EF.DG16 of the logical MRTD (FDP_ACF.1.2, rule 1) and terminals are not allowed to modify any of the data groups EF.DG1 to EF.DG16 of the logical MRTD (cf. FDP_ACF.1.4). The SFR FMT_SMR.1 lists the roles (including Personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization). The authentication of the terminal as Personalization Agent shall be performed by TSF according to SRF FIA_UAU.4, FIA_UAU.5 and FIA_UAU.6 using either FCS_COP.1/ENC and FCS_COP.1/MAC or FCS_COP.1/AUTH. The security objective OT.Data_Int “Integrity of personal data” requires the TOE to ensure that the inspection system is able to detect any modification of the transmitted logical MRTD data by means of the BAC mechanism. The SFR FIA_UAU.6, FDP_UCT.1 and FDP_UIT.1 requires the protection of the transmitted data by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1, FCS_COP.1/SHA, FCS_RND.1 (for key generation), and FCS_COP.1/ENC and FCS_COP.1/MAC for the ENC_MAC_Mode. The SFR FMT_MTD.1/KEY_WRITE requires the Personalization Agent to establish the Document Basic Access Keys in a way that they cannot be read by anyone in accordance to FMT_MTD.1/KEY_READ. The security objective OT.Data_Conf “Confidentiality of personal data” requires the TOE to ensure the confidentiality of the logical MRTD data groups EF.DG1 to EF.DG16. The SFR FIA_UID.1 and FIA_UAU.1 allow only those actions before identification respective authentication which do not violate OT.Data_Conf. In case of failed authentication attempts FIA_AFL.1 enforces additional waiting, time prolonging the necessary amount of time for facilitating a brute force attack. The read access to the logical MRTD data is defined by the FDP_ACC.1 and FDP_ACF.1.2: the successful authenticated Personalization Agent is allowed to read the data of the logical MRTD (EF.DG1 to EF.DG16). The successful authenticated Basic Inspection System is allowed to read the data of the logical MRTD (EF.DG1, EF.DG2 and EF.DG5 to EF.DG16). The SFR FMT_SMR.1 lists the roles (including Personalization Agent and Basic Inspection System) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization for the key management for the Document Basic Access Keys). The SFR FIA_UAU.4 prevents reuse of authentication data to strengthen the authentication of the user. The SFR FIA_UAU.5 enforces the TOE to accept the authentication attempt as Basic Inspection System only by means of the Basic Access Control Authentication Mechanism with the Document Basic Access Keys. Moreover, the SFR FIA_UAU.6 requests secure messaging after successful authentication of the terminal with Basic Access Control Authentication Mechanism which includes the protection of the transmitted data in ENC_MAC_Mode by means of the cryptographic functions according to FCS_COP.1/ENC and FCS_COP.1/MAC (cf. the SFR FDP_UCT.1 and FDP_UIT.1). (for key generation), and FCS_COP.1/ENC and FCS_COP.1/ MAC for the ENC_MAC_Mode. The SFR FCS_CKM.1, FCS_CKM.4, FCS_COP.1/SHA and FCS_RND.1 establish the key management for the secure messaging keys. The SFR FMT_MTD.1/KEY_WRITE addresses the key management and FMT_MTD.1/KEY_READ prevents reading of the Document Basic Access Keys. Note, neither the security objective OT.Data_Conf nor the SFR FIA_UAU.5 requires the Personalization Agent to use the Basic Access Control Authentication Mechanism or secure messaging. The security objective OT.Identification “Identification and Authentication of the TOE” address the storage of the IC Identification Data uniquely identifying the MRTD’s chip in its non-volatile memory. This will be ensured by TSF according to SFR FAU_SAS.1. IDentity Applet v.3.4/BAC/AA Security Target Page 78 of 96 Furthermore, the TOE shall identify itself only to a successful authenticated Basic Inspection System in Phase 4 “Operational Use”. The SFR FMT_MTD.1/INI_ENA allows only the Manufacturer to write Initialization Data and Pre-personalization Data (including the Personalization Agent Key). The SFR FMT_MTD.1/INI_DIS allows the Personalization Agent to disable Initialization Data if their usage in the phase 4 “Operational Use” violates the security objective OT.Identification. The SFR FIA_UID.1 and FIA_UAU.1 do not allow reading of any data uniquely identifying the MRTD’s chip before successful authentication of the Basic Inspection Terminal and will stop communication after unsuccessful authentication attempt. In case of failed authentication attempts FIA_AFL.1 enforces additional waiting, time prolonging the necessary amount of time for facilitating a brute force attack. The security objective OT.Prot_Abuse-Func “Protection against Abuse of Functionality” is ensured by the SFR 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 MRTD’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 SFR 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.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. The security objective OT.Active_Auth_Proof “Proof of travel document’s chip authenticity” is ensured by the Active Authentication Mechanism [14] 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. This key can either be written to the TOE as defined by FMT_MTD.1/AAPK or created on the TOE itself as supported by FCS_CKM.1/AA_GEN. The Active Authentication Protocol requires additional TSF according to FCS_COP.1/EMRTD. 6.3.2.

IDentity Applet v.3.4/BAC/AA Security Target Page 81 of 96 Table 11 Dependencies between the SFR for the TOE shows the dependencies between the SFR of the TOE. Justification for non-satisfied dependencies between the SFR for TOE: Justification 1 The Active Authentication key pair cannot be used for a generic cryptographic operation but only for Active Authentication acc. to FIA_API.1/AA. The Active Authentication key pair cannot be deleted or regenerated. Justification 2 The hash algorithm required by the SFR FCS_COP.1/SHA does not need any key material. Therefore, neither a key generation (FCS_CKM.1) nor an import (FDP_ITC.1/2) is necessary. Justification 3 The SFR FCS_COP.1/AUTH uses the symmetric Personalization Agent Key permanently stored during the Pre-Personalization process (cf. FMT_MTD.1/INI_ENA) by the manufacturer. Thus, there is neither the necessity to generate or import a key during the addressed TOE lifecycle by the means of FCS_CKM.1 or FDP_ITC. Since the key is permanently stored within the TOE there is no need for FCS_CKM.4, too. Justification 4 This SFR is not used to calculate any shared secrets, nor does it import user data. Therefore, there is no need for security attributes. Justification 5 The access control TSF according to FDP_ACF.1 uses security attributes which are defined during the personalization and are fixed over the whole lifetime of the TOE. No management of these security attribute (i.e. SFR FMT_MSA.1 and FMT_MSA.3) is necessary here. Justification 6 The SFR FDP_UCT.1 and FDP_UIT.1 require the use secure messaging between the MRTD and the BIS. There is no need for SFR FTP_ITC.1, e.g. to require this communication channel to be logically distinct from other communication channels since there is only one channel. Since the TOE does not provide a direct human interface a trusted path as required by FTP_TRP.1 is not applicable here. 6.3.3. Security Assurance Requirements Rationale The EAL4 was chosen to permit a developer to gain maximum assurance from positive security engineering based on good commercial development practices which, through rigorous, do not require substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at which it is likely to be economically feasible to retrofit to an existing product line. EAL4 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 MRTD’s development and manufacturing especially for the secure handling of the MRTD’s material. IDentity Applet v.3.4/BAC/AA Security Target Page 82 of 96 The component ALC_DVS.2 augmented to EAL4 has no dependencies to other security requirements Dependencies ALC_DVS.2: no dependencies. 6.3.4. 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: The dependency analysis in section 6.3.2 Dependency Rationale 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-satisfied dependencies are appropriately explained. The assurance class EAL4 is an established set of mutually supportive and internally consistent assurance requirements. The dependency analysis for the sensitive assurance components in section 6.3.3 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. The additions made to include the Active Authentication Mechanism have been integrated in a consistent way to the model designed by the [18], e. g. by using the subject, object and operation definitions. 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 sections Dependency Rationale and Security Assurance Requirements Rationale. Furthermore, as also discussed in section Security Assurance Requirements Rationale, the chosen assurance components are adequate for the functionality of the TOE. So, 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. IDentity Applet v.3.4/BAC/AA Security Target Page 83 of 96 7. TOE summary specification This chapter gives the overview description of the different TOE Security Functions composing the TSF. The mapping in-between the TSFs and SFRs can be found in Table 13 Mapping of SFRs to mechanisms of TOE. 7.1. TOE Security Functions 7.1.1. TSF.AccessControl The TOE provides access control mechanisms that allow the maintenance of different security roles according to FMT_SMR.1 Security roles (Manufacturer, Personalisation Agent, Basic Inspection System) and the access control policies and functions (FDP_ACC.1, FDP_ACF.1). Manufacturer role The TOE restricts the ability to write the Initialisation Data and Pre-personalisation Data to the Manufacturer. Manufacturer is the only role with the capability to store the IC Identification Data in the audit records. Users of role Manufacturer are assumed default users by the TOE during the Phase 2. The TSF.AccessControl provides that the Manufacturer role is only valid in Pre-personalisation of OS according to [8].1.3.2 TOE Life Cycle. Personalisation Agent role Personalisation Agent is the only role with the ability: • to disable read access for users to the Initialisation Data. • to write the initial CVCA Public Key, the initial CVCA Certificate, and the initial Current Date. • to write and to read the data of the EF.COM, EF.SOD, EF.DG1 to EF.DG16 of the logical travel document after successful authentication (until the end of the Personalisation Phase). • to read out the Initialisation Data and the Pre-personalisation Data. The Personalisation Agent has the ability to create or load the Chip Authentication Private Key. The TSF.AccessControl provides that the Personalisation Agent role is only valid in Personalisation phase of IDentity Applet life cycle. Basic Inspection System role The Basic Inspection System authenticate based on MRZ according to BAC protocol. A Basic Inspection System is not authorized to access sensitive data such as biometric data (EF.DG3, EF.DG4) The TSF.AccessControl provides that the Basic Inspection System role is only valid in Operational phase of IDentity Applet life cycle. The TSF.AccessControl ensures that nobody is allowed to read all TOE intrinsic secret cryptographic keys stored in the travel document, such the Personalisation Agent Keys, and the Active Authentication Private Key IDentity Applet v.3.4/BAC/AA Security Target Page 84 of 96 Any terminal is explicitly denied modifying any of the EF.DG1 to EF.DG16 of the logical travel document in operational phase The TSF provides functionality for the following SFRs: FDP_ACC.1: It is a requirement about access control and authentication, the access control is provided by TSF.AccessControl, the authentication control is provided by TSF.Authenticate. FDP_ACF.1: It is a requirement about access control and authentication. The access control is provided by TSF.AccessControl, the authentication control is provided by TSF.Authenticate. FIA_UAU.5: The requirement is about multiple authentication mechanisms. It is realized by TSF.Authenticate, TSF.AccessControl and the TSF.Platform. FMT_MTD.1/AAPK This requirement about the restriction the ability of creation or loading the Active authentication key pair. It is provided by TSF.AccessControl TSF.Authenticate and TSF.SecureManagement. FMT_MTD.1/KEY_READ This requirement about the restriction the ability of reading Document Basic Access Keys, Personalization Agent Keys and Active Authentication Private Key. It is provided by TSF.AccessControl TSF.Authenticate and TSF.SecureManagement. FMT_MTD.1/KEY_WRITE: This requirement is about restriction of the ability to write the Document Basic Access Keys to the Personalisation Agent. It is provided by TSF.AccessControl TSF.Authenticate and TSF.SecureManagement. FMT_SMR.1: Requires the maintenance of security roles, this is realized by TSF.AccessControl, the authentication control is provided by TSF.Authenticate and the Manufacturer role is ensured by TSF.Platform. 7.1.2. TSF.Authenticate After activation or reset of the TOE no user is authenticated. TSF-mediated actions on behalf of a user require the user’s prior successful identification and authentication. The Platform contains a deterministic random number generator rated DRG.3 (high) according to AIS20 [16] that provides random numbers used for the authentication. Proving the identity of the TOE is supported by the following means: • Basic Access Control Authentication Protocol • Passive Authentication Mechanism. Proving the genuineness of the TOE is supported by the following means: • Active Authentication Mechanism. The TOE prevents reuse of authentication data related to: • Basic Access Control Authentication mechanism • Symmetric Authentication Mechanism based on AES or TDES; IDentity Applet v.3.4/BAC/AA Security Target Page 85 of 96 The TOE implements the following authentication mechanism: • Symmetric Authentication Mechanism; • Basic Access Control; • Active Authentication; Symmetric Authentication Mechanism In the Personalisation Phase of the TOE life cycle the TSF.Authenticate enforces to the Personalisation Agent authenticates itself to the TOE by usage of the Personalisation Agent Keys with the following Symmetric Authentication Mechanism. The Symmetric Authentication mechanism has role in the Personalisation phase, when the TSF data for BAC are not available (MRZ). The TOE knows two kinds of Symmetric Authentication Mechanism: • The first one is based on Global Platform keys. • The second one is based on Personalization Agent Key (ISO secure messaging). BAC Basic Access Control checks that the terminal has physical access to the MRTD’s data page. This is enforced by requiring the terminal to derive an authentication key from the optically read MRZ of the MRTD. Basic Access Control protocol based on ISO/IEC 11770-2 key establishment mechanism 6. The BAC uses MRZ, which are not effectively represent secrets, but are restricted revealable. TSF.Authenticate provides after successful run of BAC the secure messaging (confidentiality, integrity and authenticity of communication) and for the terminal the Basic Inspection System role. Active Authentication TSF.Authenticate is able to Active Authentication Mechanism, which is an alternative to the Chip Authentication for proof the genuineness the TOE (this security feature prevents cloning the TOE). Active Authentication is based on a challenge-response protocol which proves the knowledge of the Active Authentication Private Key of the TOE. The Active Authentication Key Pair is a chip individual key pair, which contains: • Active Authentication Public Key stored in EF.DG15 and signed by Document Signer (proofed the authenticity by passive authentication). The signature is in Documents Security Objects. • Active Authentication Private Key stored in the secure memory (provided by the Platform) of the TOE. Prerequisites of the Active Authentication are the following: • Successful BAC and Passive Authentication. Active Authentication is not mandatory, but optional.

It is provided by TSF.AccessControl TSF.Authenticate and TSF.SecureManagement. FMT_SMF.1: The requirement is about performable management functions, which is provided by TSF.SecureManagement and partly used the TSF.Platform 7.1.4. TSF.CryptoKey Key Generation The TSF.CryptoKey provides the following key generation: Active Authentication ECC and RSA are supported key generation algorithm by TSF.CryptoKey. RSA PKCS#1 v2.2, RSA PKCS#1-PSS and ECDSA are supported digital signature creation cryptographic algorithm. The Active Authentication Private Key is stored in the chip secure memory (provided by TSF.Platform) and the Active Authentication Public Key is stored in EF.DG15 (protected by Passive Authentication). BAC Key Establishment Mechanism: ISO/IEC 11770-2 key establishment mechanism 6. BAC Session keys derivation: 3DES session keys in CBC mode for message encryption and message authentication (BAC-KMAC, BAC-KENC). Key Usage The Personalisation Agent Symmetric Authentication Mechanism: • In case of secure messaging (ISO) scenario, by an off-card entity having the SK.PERS key contained, by IDentity instance. SK.PERS is created in the Configuration Phase. • In case of secure messaging (GP) scenario by an off-card entity having the IDentity instance’s associated Security Domain keys, which have to be set unique value for each individual card during the Operating System (JCOP4) pre-personalisation. A successfully authenticated Personalisation Agent is allowed to change the Personalisation Agent Keys. The Personalization Agent Keys are stored by the Platform. The Active Authentication Key Pair is unchangeable in the operation phase. The TSF.CryptoKey support the Active Authentication and it is responsible for the digital signature creation. The TSF.CryptoKey is responsible for the cryptographic operation related to the secure messaging. IDentity Applet v.3.4/BAC/AA Security Target Page 88 of 96 The TSF.CryptoKey prevents to reuse ephemeral key pairs and the session keys by freshly generated random number (provided by TSF.Platform (DRG.3)). Key Destruction The TSF.CryptoKey is responsible for destroying cryptographic keys in the following events: i. SK.PERS key is automatically destroyed and not available any more in Operational Phase. ii. the BAC Session Keys: a. after detection of an error in verification of the MAC of a received command, b. any session keys before starting the communication with the terminal in a new power-on- session.

TSF.AppletParametersSign During the IDentity Applet life cycle phases after LOADED state the IDentity Applet becomes the default Application and reaches SELECTABLE state. This is called the Initialization phase. During this phase the following steps are carried out: • Applet configuration • File creation (all control parameters) • Object creation (all control parameters and some usage parameters) Certain configuration and control parameters are signed, and this signature is verified before closing the Initialization phase. Only the unsigned parameters can be changed by the Initializer. This way only those Application Profiles can be applied which are validated by the Developer and conform to the requirements. The Initialization state cannot be finished by reaching the INITIALIZED state, and the Personalization phase cannot be started without successful signature verification. These signatures can be verified during the whole IDentity Applet life-cycle, thus the non-authorized changed become detectable by applying this SF. The TSF provides functionality for the following SFRs: FPT_TST.1: Requires self-test and capability to verify integrity of TSF and TSF data. This is provided by TSF.AppletParametersSign and TSF.Platform. 7.1.6.
