The TOE life cycle is described in § 3. The TOE identification is described in § 1.3.1. The TOE scope encompasses the following features: Basic Access Control Active Authentication Chip Authentication Nevertheless, the TOE in the LDS application embeds other secure functionalities they are not in the scope of this evaluation and are in the scope of other evaluations. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 20 | 80 2.1.1 Physical scope The TOE is physically made up of several components hardware and software. Once constructed, the TOE is a bare microchip with its external interfaces for communication. The physical medium on which the microchip is mounted is not part of the target of evaluation because it does not alter nor modify any security functions of the TOE. The TOE may be used on several physical medium within an inlay, or eCover; in a plastic card. The physical form of the module is depicted in Figure below. The cryptographic boundary of the module is the surface and edges of the die and associated bond pads, shown as circles in the following figure. Figure 2: Physical Form The contactless ports of the module require connection to an antenna. The module relies on [ISO7816] and [ISO14443] card readers and antenna connections as input/output devices. Port Description Logical Interface Type VCC, GND ISO 7816: Supply voltage Power (not available in contactless‐only configurations) RST ISO 7816:Reset Control in (not available in contactless‐only configurations) CLK ISO 7816: Clock Control in (not available in contactless‐only configurations) I/O ISO 7816: Input/ Output Control in, Data in, Data out, Status out (not available in contactless‐only configurations) LA, LB ISO 14443: Antenna Power, Control in, Data in, Data out, Status out (Not available in Contact‐only configurations) Table 7: Ports and Interfaces 2.1.2 Required non-TOE hardware/software/firmware The TOE is an MRTD. It is an independent product and does not need any additional hardware/software/firmware to ensure its security. In order to be powered up and to be able to communicate the TOE needs a card reader. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 21 | 80 2.1.3 TOE Usage and major security features State or organisation issues MRTDs to be used by the holder to prove his/her identity and claiming associated rights. For instance, it can be used to check identity at customs in an MRTD configuration, verifying authenticity of electronic visa stored on the card and correspondence with the holder. In order to pass successfully the control, the holder presents its personal MRTD to the inspection system to first prove his/her identity. The inspection system is under control of an authorised agent and can be either a desktop device such as those present in airports or a portable device to be used on the field. The MRTD in context of this security target contains: - Visual (eye readable) biographical data and portrait of the holder printed in the booklet - A separate data summary (MRZ or keydoc data) for visual and machine reading using OCR methods in the Machine Readable Zone (MRZ or keydoc area) - And data elements stored on the TOE’s chip for contact-less machine reading. The authentication of the holder is based on: - The possession of a valid MRTD personalized for a holder with the claimed identity as given on the biographical data page and - The Biometric matching performed on the Inspection system using the reference data stored in the MRTD. When holder has been authenticated the issuing State or Organization can performed extra authentications in order to gain rights required to grant access to some sensitive information such as “visa information”. The issuing State or Organization ensures the authenticity of the data of genuine MRTDs. The receiving State trusts a genuine MRTD of an issuing State or Organization. The MRTD can be viewed as the combination: A physical MRTD in form of paper or plastic with an embedded chip and possibly an antenna. It presents visual readable data including (but not limited to)  personal data of the MRTD holder  The biographical data on the biographical data page of the passport book  The printed data in the Machine-Readable Zone (MRZ) or keydoc area that identifies the device  The printed portrait A logical MRTD as data of the MRTD holder stored according to the Logical Data Structure as specified by ICAO and extended in [44][45][46] on the contactless integrated circuit. It presents contact or contact-less readable data including (but not limited to)  personal data of the MRTD holder  The digital Machine Readable Zone Data (digital MRZ data or keydoc data, DG1)  The digitized portraits  The optional biometric reference data of finger(s) or iris image(s) or both  The other data according to LDS (up to DG24)  The Document security object The issuing State or Organization implements security features of the MRTD to maintain the authenticity and integrity of the MRTD and its data. The MRTD as the physical device and the MRTD’s chip is uniquely identified by the document number. The physical MRTD is protected by physical security measures (e.g. watermark on paper, security printing), logical (e.g. authentication keys of the MRTD’s chip) and organisational security measures (e.g. control of materials, personalization procedures). These security measures include the binding of the MRTD’s chip to the physical support. The logical MRTD is protected in authenticity and integrity by a digital signature created by the document signer acting for the issuing State or Organization and the security features of the MRTD’s chip. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 22 | 80 2.2 TOE Definition The Target of Evaluation (TOE) is the contactless integrated circuit chip of machine readable travel documents (MRTD’s chip) programmed according to the Logical Data Structure (LDS) and providing the Basic Access Control according to ‘ICAO Doc 9303’[43] . The TOE allows also Active Authentication and Chip Authentication. The TOE comprises at least:  Circuitry of the MRTD’s chip (the integrated circuit, IC)  IC Dedicated Software with the parts IC Dedicated Test Software and IC Dedicated Support Software  Cosmo V8.2 Platform  API  LDS V10.1 application  Associated guidance documentation The platform provides an operational environment for the application: all cryptographic algorithm implementations and associated self-tests, random number and key generation, card lifecycle management, and key storage and protection are provided by the platform. The code for this functionality is contained in the platform ROM. However, the factory configuration of the module constrains the module to the set of services provided by the platform’s Card Manager (implementing a standard set of GlobalPlatform services), The applet may be used on a contact mode compliant to ISO/IEC 7816-3 specification or on contactless mode compliant to ISO/IEC 14443 specification. 2.3 TOE Architecture The TOE is a smartcard, composed of IC, Java Card Platform and the LDS application. Other applications may reside in the TOE. 2.3.1 Integrated Circuit The TOE is embedded on NXP chips; more information on the chips is given in the related public Security Target identified in table 3 of chapter 1.3.2. 2.3.2 Java Card Platform The Operating System is based on Java Card Technology and Global Platform technology. His main responsibilities are:  providing interface between the Integrated Circuit and the applet  providing to the applet, basic services to access to memories and all needed cryptographic operations  ensuring global management of the card (loading, installation and deletion of applets) and monitor the security of the card (data integrity and physical attacks counter- measures). For details see [54]. 2.3.3 Application Functionalities This application stores the personal information related to the cardholder of an MRTD or an IDL. It also allows governmental organizations to retrieve these pieces of data. The applet supports the authentication mechanisms described in ICAO and EAC specifications and ISO/IEC 18013-3 ISO Compliant Driving License specification with a fully configurable access control management over the EFs (EFs). The applet may be used on a contact mode (compliant to ISO/IEC 7816-3 specification) and/or contactless mode (compliant to ISO/IEC 14443 specification). LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 23 | 80 The compliancy of the applet to LDS, EAC, or IDL, is achieved provided a correct personalization is performed. The correct authentication mechanisms and access conditions over the EFs must be assigned. In summary, the applet supports the following authentication mechanisms stated in the ICAO specifications (for MRTD) and the ISO Compliant Driving License standard (for IDL): • Active Authentication (AA) • Basic Access Control (BAC) / Basic Access Protection Mode 1 (BAP1) • Password Authenticated Connection Establishment (PACE) • Extended Access Control (EAC) • Chip Authentication Mapping (CAM) All authentication mechanisms are listed in the following chapters, all are part of the product but only some are part of the present evaluation. 2.3.3.1 Active Authentication (AA) Active Authentication is an authentication mechanism ensuring the chip is genuine. It uses a challenge- response protocol between the IS and the chip. Active Authentication is realized with the INTERNAL AUTHENTICATE command. The key and algorithms supported are the following: RSA ISO/IEC 9796-2 with a key length of 1024 bits, 1536 bits or 2048 bits and hashing algorithm of SHA1 or SHA2. ECDSA over prime field curves with hashing algorithm of SHA1 or SHA2 and the key sizes 192 to 512. AES-256 using ISO/IEC 9797-1 M2 padding method. TDES with double and triple length keys using ISO/IEC 9797-1 M2 padding method. 2.3.3.2 Basic Access Control (BAC) The protocol for Basic Access Control is specified by ICAO [47] 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. The protocol for Basic Access Control is based on ISO/IEC 11770-2 [41] key establishment mechanism 6. This protocol is also used to generate session keys that are used to protect the confidentiality (and integrity) of the transmitted data. The Basic Access Control (BAC) is a security feature that is supported by the TOE. The inspection system: Reads the printed data in the MRZ (for MRTD), Authenticates itself as inspection system by means of keys derived from MRZ data. After successful 3DES based authentication, the TOE provides read access to data requiring BAC rights by means of a private communication (secure messaging) with the inspection system. The purpose of this mechanism is to ensure that the holder gives access to the IS to the logical MRTD (data stored in the chip); It is achieved by a mutual authentication. Once the mutual authentication is performed, a secure messaging is available to protect the communication between the chip and the IS. This table lists the supported configurations for BAC protocol: Configuration Key Algo Key Length Hash Algo MAC Algo BAC 3DES 2Key 16-bytes SHA-1 Retail MAC Table 8: BAC Configuration 2.3.3.3 Terminal Authentication The Terminal Authentication Protocol is a two move challenge-response protocol that provides explicit unilateral authentication of the terminal. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 24 | 80 This protocol enables the MRTD chip to verify that the terminal is entitled to access sensitive data. As the terminal may access sensitive data afterwards, all further communication MUST be protected appropriately. Terminal Authentication therefore also authenticates an ephemeral public key chosen by the terminal that was used to set up Secure Messaging with Chip Authentication. The MRTD chip MUST bind the terminal’s access rights to Secure Messaging established by the authenticated ephemeral public key of the terminal. 2.3.3.4 Chip Authentication The Chip Authentication Protocol is an ephemeral-static Diffie-Hellman key agreement protocol that provides secure communication and unilateral authentication of the MRTD chip. The protocol establishes Secure Messaging between an MRTD chip and a terminal based on a static key pair stored on the MRTD chip. Chip Authentication is an alternative to the optional ICAO Active Authentication, i.e. it enables the terminal to verify that the MRTD chip is genuine but has two advantages over the original protocol: Challenge Semantics are prevented because the transcripts produced by this protocol are non-transferable. Besides authentication of the MRTD chip this protocol also provides strong session keys. The protocol in version 1 provides implicit authentication of both the MRTD chip itself and the stored data by performing Secure Messaging using the new session keys. The protocol in Version 2 provides explicit authentication of the MRTD chip by verifying the authentication token and implicit authentication of the stored data by performing Secure Messaging using the new session keys. 2.3.3.5 Password Authenticated Connection Establishment (PACE) PACE is an access control mechanism that is supplemental to BAC. It is a cryptographically stronger access control mechanism than BAC since it uses asymmetric cryptography compared to BAC’s symmetric cryptography. PACE is realized through 5 commands: 1. MSE SET – AT command 2. GENERAL AUTHENTICATE command – Encrypted Nonce 3. GENERAL AUTHENTICATE command – Map Nonce 4. GENERAL AUTHENTICATE command – Perform Key Agreement 5. GENERAL AUTHENTICATE command – Mutual Authentication Once the mutual authentication is performed, a secure messaging is available to protect the communication between the chip and the IS. This table lists the supported configurations for PACE protocol: Configuration Mapping Key Algo Key Length (in bytes) Secure Messaging Auth. Token Hash Algo PACE–ECDH–GM–3DES Generic 3DES 2Key 16 CBC / Retail MAC Retail MAC SHA- 1 PACE–ECDH–GM–AES– 128 Generic AES 16 CBC / CMAC CMAC SHA- 1 PACE–ECDH–GM–AES– 192 Generic AES 24 CBC / CMAC CMAC SHA- 256 PACE–ECDH–GM–AES– 256 Generic AES 32 CBC / CMAC CMAC SHA- 256 PACE–ECDH–IM–3DES Integrated 3DES 2Key 16 CBC / Retail MAC Retail MAC SHA- 1 LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 25 | 80 PACE–ECDH–IM–AES–128 Integrated AES 16 CBC / CMAC CMAC SHA- 1 PACE–ECDH–IM–AES–192 Integrated AES 24 CBC / CMAC CMAC SHA- 256 PACE–ECDH–IM–AES–256 Integrated AES 32 CBC / CMAC CMAC SHA- 256 PACE–ECDH–CAM–AES– 128 Chip Authentication AES 16 CBC / CMAC CMAC SHA- 1 PACE–ECDH–CAM–AES– 192 Chip Authentication AES 24 CBC / CMAC CMAC SHA- 256 PACE–ECDH–CAM–AES– 256 Chip Authentication AES 32 CBC / CMAC CMAC SHA- 256 Table 9: PACE Configuration 2.3.3.6 Extended Access Control (EAC) EAC is an authentication protocol based on a PKI infrastructure. It further ensures that the IS is authorized to read and/or update data stored in the applet. This authentication mechanism generates a strong secure messaging session through the step of Chip Authentication. This mechanism is realized by the following steps: 1. Chip Authentication (CA)Chip Authentication is achieved by using a MANAGE SECURITY ENVIRONMENT – SET – Key Agreement Template (MSE SET KAT) command or by using a MANAGE SECURITY ENVIRONMENT – SET – Authentication Template (MSE SET AT) command followed by GENERAL AUTHENTICATE command. The Chip Authentication mechanism enables the authentication of the chip by using an authenticated DH scheme. It may be realized in two ways:  Classical DH (DH El Gamal) with key length of 1024, 1536, or 2048 bits  DH over Elliptic curves over prime fields (ECDH) with the key length supported by the underlying Java Card platform. 2. Certificate Chain Handling The certificate chain is processed through a series of MANAGE SECURITY ENVIRONMENT – SET – Digital Signature Template (MSE SET DST) and PERFORM SECURITY OPERATION – Verify Certificate (PSO VERIFY) commands. The chain is done to extract a key from the IS certificate, the key which will be used in the Terminal Authentication. 3. Terminal Authentication (TA) Terminal Authentication is achieved by using an EXTERNAL AUTHENTICATE command. The Terminal Authentication mechanism is an authentication of the IS based on a classical challenge/response scheme. The signature scheme may be: ECDSA SHA-1, ECDSA SHA-224, ECDSA SHA-256, ECDSA SHA-384, or ECDSA SHA-512 on elliptic curves over prime field with key length supported by the underlying Java Card platform RSA SHA-1, SHA-256, or SHA-512 (PKCS#1 v1.5 or PKCS#1 v2.1 - PSS) with a key length of 1024, 1536, and 2048 bits. 2.3.3.7 PACE-CAM The Chip Authentication Mapping is a new mapping for PACE which extends the Generic Mapping that integrates Chip Authentication into the PACE protocol. This mapping combines PACE and Chip Authentication LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 26 | 80 into one protocol PACE-CAM, which allows faster execution than the separate protocols (i.e. PACE + CA + TA). PACE-CAM is realized the same way as § 2.3.3.6. The only difference is that the chip computes the Chip Authentication Data using the chip’s static private key then sends this data to the terminal. The terminal verifies the authenticity of the chip using the recovered Chip Authentication Data. 2.3.3.8 Match On-Card (MOC) Verification MOC verification may be used to grant some access rights to EFs. This feature relies on the services provided by the CHV Server applet MOC verification is supported if the CHV Configuration is properly configured in the install parameter. Once the MOC verification is allowed the applet will permit the use of CHV-related commands that handles biometric and Global PIN credentials. 2.3.3.9 PIN The product supports the management of card holder credentials such as Cardholder PIN and Global PIN which can be used to grant access rights to EFs or keys. The Cardholder PIN and Global PIN each have its PIN Unblocking Key (Cardholder PUK and Global PUK, respectively). These PINs and corresponding PUKs have to be initialized during personalization if they are used to protect access to EFs and keys. 2.3.3.10 Watermarking The watermarking feature may be used to restrict the access to the plain image data of particular EF(s). Enabling the watermarking will cause the image data to be corrupted during the reading of the file contents. The de-watermarking conditions should be configured accordingly and these conditions must be satisfied in order to grant access to the plain image data, details are in the dedicated security Target. 2.3.3.11 Secure Messaging The TOE supports the ISO Secure Messaging. It provides a secure channel (i.e. encrypted and authenticated) between application and terminal. Secure Messaging can be set up by Chip Authentication, PACE, or Basic Access Control. The provided security level depends on the mechanism used to set up Secure Messaging. A session is started when secure messaging is established. The session only ends with the release of secure messaging, e.g. by sending a command without secure messaging. 2.3.3.12 IDEMIA library A dedicated cryptographic library has been developed and designed by IDEMIA. This cryptographic library is embedded on the TOE to provide the highest security level and best tuned performances. It is implemented at the platform level and are already in the scope of the platform evaluation. 2.3.4 Mechanism included in the scope of the evaluation All TOE functionalities are presented in the previous chapter.

The roles involved in the different steps are listed in the following table: Roles Subjects IC manufacturer NXP Semiconductors TOE developer IDEMIA Manufacturer NXP Semiconductors IDEMIA or another agent LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 29 | 80 Pre-personalizer IDEMIA or another agent Personalization Agent IDEMIA or another agent Table 11: Roles Identification on the life cycle. The table below presents the subjects following TOE life cycle steps in accordance with the standard smart card life cycle, the Protection Profile lifecycle in phases, the TOE delivery point and the coverage: Steps Phase Subject Covered by Step 1 Development IDEMIA ALC R&D sites Step 2 Development NXP Semiconductors IC certification Step 3 Manufacturing NXP Semiconductors IC certification TOE delivery point Step 4 Manufacturing MRD Manufacturer (Pre- personalizer) AGD_PRE Step 5 Manufacturing MRD Manufacturer (Pre- personalizer) AGD_PRE Step 6 Personalization Personalization Agent AGD_PRE Step 7 Operational Use End user AGD_OPE Table 12: Subjects identification following life cycle steps Details for each phase/step are presented in the following paragraphs. 3.2 Phase 1 “Development” (Step1) The TOE is developed in phase 1. The IC developer develops the integrated circuit, the IC Dedicated Software and the guidance documentation associated with these TOE components. The TOE includes the LDS V10.1 application and the Platform. The LDS Applet and the Platform are both developed at IDEMIA R&D Sites. The sites are audited following MSSR last requirements. (Step2) The TOE 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 MRTD application and the guidance documentation associated with these TOE components. The manufacturing documentation of the IC including the IC Dedicated Software and the Embedded Software in the non-volatile non-programmable memories is securely delivered to the IC manufacturer. The IC Embedded Software in the non-volatile programmable memories, the eMRTD application and the guidance documentation is securely delivered to the Manufacturer. 3.3 Phase 2 “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). 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 Manufacturer. The IC is securely delivered from the IC manufacture to the Manufacturer. If necessary the IC manufacturer adds the parts of the IC Embedded Software in the non-volatile programmable memories (for instance EEPROM). The IC manufacturer adds initialization data in EEPROM and keys (MSK, LSK). The end of step 3 is the TOE delivery. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 30 | 80 (Step4) The Manufacturer combines the IC with hardware for the contact based / contactless interface in the travel document unless the travel document consists of the card only. (Step5) The Manufacturer (i) adds the IC Embedded Software (ii) creates the eMRTD application, and (iii) equips travel document’s chips with pre-personalization Data. The pre-personalised travel document together with the IC Identifier is securely delivered from the Manufacturer to the Personalization Agent. The Manufacturer also provides the relevant parts of the guidance documentation to the Personalization Agent. 3.4 Phase 3 “Personalization of the travel document” (Step6) The personalization of the travel document includes: 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 personalization 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 Personalization 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. The signing of the Document security object by the Document signer finalizes the personalization of the genuine travel document for the travel document holder. The personalised travel document (together with appropriate guidance for TOE use if necessary) is handed over to the travel document holder for operational use. 3.4.1 Loading of application The platform can host 2 kinds of applications: Evaluated sensitive applications and validated basic applications. Once the application is evaluated or validated, it is securely delivered to manufacturing site. This delivery ensures the integrity and confidentiality of the application code and data. Then applications code and data are securely stored. The delivery, storage and loading of any application are covered by audited Organisational measures (ALC). Applications can be loaded at pre issuance at step 5 or at step 6 or in post issuance. 3.4.2 Applet pre-personalisation (phase 6) This phase is performed by the Personalisation Agent, which controls the TOE. During this phase, the Java Card applet is prepared as required by P.TOE_Construction. All along this phase, the TOE is self-protected as it requires the authentication of the Personalisation Agent prior to any operation. 3.4.3 TOE personalisation (phase 6) This phase is performed by the Personalisation Agent, which controls the TOE, which is in charge of the Java Card applet personalisation. All along this phase, the TOE is self-protected as it requires the authentication of the Personalisation Agent prior to any operation. This phase may not necessarily take place in a manufacturing site, but may be performed anywhere. The Personalisation Agent is responsible for ensuring a sufficient level of security during this phase. The Java Card applet is personalized according to guidance document [57]. At the end of phase 6, the TOE is constructed. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 31 | 80 3.5 Phase 4 “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 Organisation and can be used according to the security policy of the issuing State but they can never be modified. Note that the personalization process and its environment may depend on specific security needs of an issuing State or Organisation. 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. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 32 | 80 4 Conformance Claim 4.1 Conformance claim This security target claims conformance to the Common Criteria version 3.1, revision 5 ([1][2][3]). The conformance to the Common Criteria is claimed as follows: CC Conformance rationale Part 1 Strict conformance Part 2 Conformance to the extended1 part: FAU_SAS.1 “Audit Storage” FCS_RND.1 “Quality metric for random numbers” FMT_LIM.1 “Limited capabilities” FMT_LIM.2 “Limited availability” FPT_EMS.1 “TOE Emanation” FIA_API.1 “Authentication Proof of Identity” Part 3 Strict conformance to Part 3. The product claims conformance to EAL 4, augmented with: ALC_DVS.2 “Sufficiency of security measures” ADV_FSP.5 “Complete semi-formal functional specification with additional error information” ADV_INT.2 “Well-structured internals” ADV_TDS.4 “Semiformal modular design” ALC_CMS.5 “Development tools CM coverage” ALC_TAT.2 “Compliance with implementation standards” ATE_DPT.3 “Testing: modular design” Table 13 - Conformance Rationale Remark: For interoperability reasons it is assumed the receiving state cares for sufficient measures against eavesdropping within the operating environment of the inspection systems. Otherwise the TOE may protect the confidentiality of some less sensitive assets (e.g. the personal data of the TOE holder which are also printed on the physical TOE) for some specific attacks only against enhanced basic attack potential (AVA_VAN.3). FIA_API.1 has been added to this security target for the needs of the Chip Authentication Protocol that is described in the PP EAC. FPT_EMSEC.1 from [47] has been renamed to FPT_EMS.1, in order to keep the SFR formatting. Moreover the security target claims compliance with Application note 10 [5]. 4.2 Protection Profile claims The Security Target claims strict conformance to the following PP written in CC3.1: [47] BAC- Machine readable travel documents with “ICAO Application”, Basic Access control – BSI-PP-0055 v1.10 25th march 2009. The protection profile [47] claims conformance to:  Common Criteria for Information Technology Security Evaluation, Part 1: Introduction and General Model; CCMB-2006-09-001, Version 3.1, Revision 1, September 2006,  Common Criteria for Information Technology Security Evaluation, Part 2: Security Functional Components; CCMB-2007-09-002, Version 3.1, Revision 2, September 2007  Common Criteria for Information Technology Security Evaluation, Part 3: Security Assurance Requirements; CCMB-2007-09-003, Version 3.1, Revision 2, September 2007. 1 The rationale for SFR addition is described in the relative PP LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 33 | 80 4.3 Additions The rationale between the SPD, taking into account the additional elements of the SPD, the Objectives and Objectives on the operational environment are given in the paragraph Rationales. 4.3.1 SFR dispatch versus PP The following table present a rationale between the SFR driven from the protection profile versus the SFR from this security target: SFR from the PP Dispatch in the ST (detailed SFR in chapter 8] FAU_SAS.1 FAU_SAS.1 FCS_CKM.1 FCS_CKM.1/BAC FCS_CKM.4 FCS_CKM.4/Global FCS_COP.1/SHA FCS_COP.1/BAC_SHA FCS_COP.1/AUTH FCS_COP.1/BAC_AUTH FCS_COP.1/ENC FCS_COP.1/BAC_ENC FCS_COP.1/MAC FCS_COP.1/BAC_MAC FCS_RND.1 FCS_RND.1/Global FIA_UID.1 FIA_UID.1/BAC FIA_UAU.1 FIA_UAU.1/BAC FIA_UAU.4 FIA_UAU.4/BAC FIA_UAU.5 FIA_UAU.5/BAC FIA_UAU.6 FIA_UAU.6/BAC FIA_AFL.1 FIA_AFL.1/BAC FDP_ACC.1 FDP_ACC.1/BAC FDP_ACF.1 FDP_ACF.1/BAC FDP_UCT.1 FDP_UCT.1/BAC FDP_UIT.1 FDP_UIT.1/BAC FMT_SMF.1 FMT_SMF.1 FMT_SMR.1 FMT_SMR.1/BAC FMT_LIM.1 FMT_LIM.1/Global FMT_LIM.1/BAC FMT_LIM.2 FMT_LIM.2/Global FMT_LIM.2/BAC FMT_MTD.1/INI_ENA FMT_MTD.1/INI_ENA FMT_MTD.1/INI_DIS FMT_MTD.1/INI_DIS FMT_MTD.1/KEY_WRITE FMT_MTD.1/BAC_KEY_WRITE FMT_MTD.1/KEY_READ FMT_MTD.1/BAC_KEY_READ FPT_EMS.1 FPT_EMS.1/Global FPT_EMS.1/CA FPT_FLS.1 FPT_FLS.1/Global FPT_TST.1 FPT_TST.1/Global FPT_TST.1/CA FPT_TST.1/BAC FPT_PHP.3 FPT_PHP.3.1/Global Table 14: PP SFR 4.3.2 Overview of the SFR defined in this ST Notation: LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 34 | 80 For optimisation and ease read, all the SFR presented in chapter Security Functional Requirements have extensions as presented here: SFR (/Global) that are global to the product (shared between the various TOE) SFR (/AA) that are dedicated for Active Authentication SFR (/BAC) that are dedicated for Basic Access Control SFR (/CA) that are dedicated for Chip Authentication 4.3.3 Complete overview of the SFR From the PP, the following table lists the SFR defined in the ST with the generic notation.

For this addition, the TOE SPD has been refined and contains the following additions: Additional Threats: § 5.3.2 Threats for CA Additional Objective: § 6.1.2 SO for CA Additional OE: § 6.2.2 OE for CA 4.3.4.2 Active Authentication The additional functionality of Active Authentication (AA) is based on the ICAO PKI V1.1 and the related on- card generation of RSA and ECC keys. It implies the following addition to the standard PP: Additional Objective: § 6.1.3 SO for AA Additional OE: § 6.2.3 OE for AA 4.3.4.3 Pre-Personalization phase The pre-personalization phase has been reinforced in this Security Target, with the following elements. This functionality is usable in phase 5 and phase 6. Once the product is locked, stated as personalized, it is no more possible to perform this operation. In order to be compliant with the CEM, a rationale is given for the additional Objectives on the Environment, such as to demonstrate that they neither mitigates a threat nor fulfil an OSP. 4.3.5 OE for CA rationale OE.Exam_MRTD_CA, OE.Prot_Logical_MRTD_CA and OE.Auth_Key_MRTD define additional requirements on the operational environment for the Chip Authentication Protocol which is not in the original scope of the PP BAC. This OE is only linked to threat and OSP for the Chip Authentication and has no links with those of the PP. 4.3.6 OE for AA rationale The objectives OE.Exam_MRTD_AA, OE.Prot_Logical_MRTD_AA, OE.Activ_Auth_Verif and OE.Activ_Auth_Sign define additional requirements on the operational environment for the Active Authentication Protocol which is not in the original scope of the PP BAC. This OE is only linked to threat and OSP for the Active Authentication and has no links with those of the PP. 4.3.7 Assumption for AA rationale The A.Insp_Sys_AA is added; this assumption is only linked to Active Authentication mechanism as the Inspection System has to implement the mechanism and shall verify the authenticity of the MRTD’s chip during inspection using the signature returned by the TOE during Active Authentication. 4.3.8 Assumption for CA rationale The A.Insp_Sys_CA, The assumption A.Insp_Sys_CA serves only the Chip authentication mechanism added in the scope of the evaluation. The inspection system shall implement the CA mechanism. The IS has to verify the authenticity of the MRTD during the inspection by establishing a secure messaging. This addition has no impact on the SPD of the PP BAC. A.Signature_PKI This assumption is only linked to the Chip authentication as the issuing and receiving States or Organizations shall establish a public key infrastructure for passive authentication i.e. digital signature creation and verification for the logical MRTD. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 37 | 80 5 Security Problem Definition 5.1 Subjects SFR Before phase 5 Phase 5 Phase 6 Phase 7 PP BAC subjects Manufacturer x x Personalization Agent x Terminal x x x Inspection System x MRTD Holder x Traveler x Attacker x x x x 5.1.1 PP BAC 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 users IC Manufacturer and MRTD Manufacturer using this role Manufacturer. 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 (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 (iv) signing the Document Security Object defined in [43]. Application Note Personalization Agent is referred as the Personalizer in the Security Target. 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 (ii) 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: LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 38 | 80 This security target does not distinguish between the BIS, GIS and EIS because the Extended Access Control is outside the scope. MRTD Holder Is the rightful holder of the MRTD for whom the issuing State or Organization personalized the MRTD. Traveler Is the person presenting the MRTD to the inspection system and claiming the identity of the MRTD holder. Attacker Is a threat agent trying (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 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. Additional Subjects 5.2 Assets 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 [43]. 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 (CAPK) in 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. The Active Authentication Public Key (AAPK) Info in DG 15 is used by the inspection system for Active Authentication of the chip. All these data may be sorted out in two different categories: If they are specific to the user, they are User data If they ensure the correct behaviour of the application, they are TSF Data. User Data Description CPLC Data Data uniquely identifying the chip. They are considered as user data as they enable to track the holder Personnal Data of the MRTD holder (EF.DGx, except EF.DG15) Contains identification data of the holder Document Security Object (SOD) in EF.SOD Contain a certificate ensuring the integrity of the file stored within the MRTD and their authenticity. It ensures the data are issued by a genuine country Common data in EF.COM Declare the data the travel document contains. This data is optional and may be absent in the TOE Active Authentication Public Key in EF.DG15 (AAPK) Contains public data enabling to authenticate the chip thanks to the Active Authentication Chip Authentication Public Key in EF.DG14 (CAPK) Contains public data enabling to authenticate the chip thanks to the Chip Authentication Protocol Table 21 - User Data TSF Data Description TOE_ID Data enabling to identify the TOE LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 39 | 80 TSF Data Description Prepersonalizer reference authentication data Private key enabling to authenticate the Prepersonalizer Personalization Agent reference authentication Data Private key enabling to authenticate the Personalization Agent Basic Access Control (BAC) Key Master keys used to established a trusted channel between the Basic Inspection Terminal and the travel document Active Authentication private key (AAK) Private key the chip uses to perform an Active Authentication Chip Authentication private key (CAK) Private key the chip uses to perform a Chip Authentication Session keys for the secure channel Session keys used to protect the communication in confidentiality, authenticity and integrity Life Cycle State Life Cycle state of the TOE Table 22 - TSF Data 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. 5.3 Threats This section describes the threats to be averted by the TOE independently or in collaboration with its IT environment. These threats result from the TOE method of use in the operational environment and the assets stored in or protected by the TOE. 5.3.1 Threats from the PP BAC T.Chip_ID 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 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 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 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 LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 40 | 80 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. T.Abuse-Func 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 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 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 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 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. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 41 | 80 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. 5.3.2 Threats for CA T.Counterfeit Adverse action: An attacker with high attack potential produces an unauthorized copy or reproduction of a genuine MRTD's chip to be used as part of a counterfeit MRTD. This violates the authenticity of the MRTD's chip used for authentication of a traveller by possession of a MRTD. The attacker may generate a new data set or extract completely or partially the data from a genuine MRTD's chip and copy them on another appropriate chip to imitate this genuine MRTD's chip. Threat agent: having high attack potential, being in possession of one or more legitimate MRTDs Asset: authenticity of logical MRTD data 5.4 Organisational Security Policies 5.4.1 OSP from PP BAC P.Manufact 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 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 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)3 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 [47]. 5.4.2 OSP for CA P.Chip_Auth The terminal implements the Chip Authentication protocol as described in [48] OSP for AA P.Activ_Auth The terminal implements the Active Authentication protocol as described in [47]. 5.5 Assumptions The assumptions describe the security aspects of the environment in which the TOE will be used or is intended to be used. 5.5.1 Assumptions from PP BAC A.MRTD_Manufact LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 42 | 80 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 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. A.Pers_Agent The Personalization Agent ensures the correctness of(i) the logical MRTD with respect to the MRTD holder, (ii) the Document Basic Access Keys, (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. A.Insp_Sys The Inspection System is used by the border control officer of the receiving State (i) examining an MRTD presented by the traveler and verifying its authenticity and (ii) verifying the traveler 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. The Basic Inspection System reads the logical MRTD under Basic Access Control and performs the Passive Authentication to verify the logical MRTD. A.BAC-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" [43], 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. 5.5.2 Assumptions for Chip Authentication A.Insp_Sys_CA The Inspection System implements the Chip Authentication Mechanism. The Inspection System verifies the authenticity of the MRTD’s chip during inspection and establishes secure messaging with keys established by the Chip Authentication Mechanism. A.Signature_PKI The issuing and receiving States or Organizations establish a public key infrastructure for passive authentication i.e. digital signature creation and verification for the logical MRTD. The issuing State or Organization runs a Certification Authority (CA) which securely generates, stores and uses the Country Signing CA Key pair. The CA keeps the Country Signing CA Private Key secret and is recommended to distribute the Country Signing CA Public Key to ICAO, all receiving States maintaining its integrity. The Document Signer (i) generates the Document Signer Key Pair, (ii) hands over the Document Signer Public Key to the CA for certification, (iii) keeps the Document Signer Private Key secret and (iv) uses securely the Document Signer Private Key for signing the Document Security Objects of the MRTDs. The CA creates the Document Signer Certificates for the Document Signer Public Keys that are distributed to the receiving States and Organizations.

OT.Prot_Phys-Tamper LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 45 | 80 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 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 measuring not using galvanic contacts but other types of physical interaction between charges (using tools used in solid-state physics research and IC failure analysis) manipulation of the hardware and its security features, as well as controlled manipulation of memory contents (User Data, TSF Data) with a prioreverse-engineering to understand the design and its properties and functions. OT.Prot_Malfunction 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. 6.1.2 SO for CA OT.CA_Proof The TOE must support the Inspection Systems to verify the identity and authenticity of the MRTD’s chip as issued by the identified issuing State or Organization by means of the Chip Authentication as defined in [48]. The authenticity proof provided by the MRTD’s chip shall be protected against attacks with high attack potential. Application note: The objective implies the MRTD’s to have (i) a unique identity as given by the MRTD’s Document Number, (ii) a secret to prove its identity by knowledge i.e. a private authentication key as TSF data. The TOE shall protect this TSF data to prevent their misuse. The terminal shall have the reference data to verify the authentication attempt of MRTD’s chip i.e. a certificate for the Chip Authentication Public Key that matches the Chip Authentication Private Key of the MRTD’s chip. This certificate is provided by (i) the Chip Authentication Public Key (EF.DG14) in the LDS [43] and (ii) the hash value of the Chip Authentication Public Key in the Document Security Object signed by the Document Signer.

LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 46 | 80 6.2 Security objectives for the Operational Environment 6.2.1 OE from PP BAC 6.2.1.1 Issuing State or Organization The issuing State or Organization will implement the following security objectives of the TOE environment. OE.MRTD_Manufact Appropriate functionality testing of the TOE shall be used in step 4 to 6.

OE.MRTD_ Delivery Procedures shall ensure protection of TOE material/information under delivery including the following objectives:  non-disclosure of any security relevant information  identification of the element under delivery  meet confidentiality rules (confidentiality level, transmittal form, reception acknowledgment)  physical protection to prevent external damage  secure storage and handling procedures (including rejectd TOE"s)  traceability of TOE during delivery including the following parameters: o origin and shipment details o reception, reception acknowledgement o 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. 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 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 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 [43]. OE.BAC-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" [43] 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 LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 47 | 80 that the inspection system has to derive Document Basic Access Keys from the printed MRZ data with enhanced basic attack potential. 6.2.1.2 Receiving State or Organization The receiving State or Organization will implement the following security objectives of the TOE environment. OE.Exam_MRTD 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 [43]. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 48 | 80 OE.Passive_Auth_Verif 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 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). 6.2.2 OE for CA OE.Auth_Key_MRTD The issuing State or Organization has to establish the necessary public key infrastructure in order to: (i) Generate the MRTD's Chip Authentication Key Pair (ii) Sign and store the Chip Authentication Public Key in the Chip Authentication Public Key data in EF.DG14 (iii) Support inspection systems of receiving States or organizations to verify the authenticity of the MRTD's chip used for genuine MRTD by certification of the Chip Authentication Public Key by means of the Document Security Object. OE.Exam_MRTD_CA Aditionally to the OE.Exam_MRTD, the inspection systems perform the Chip Authentication protocol to verify the Authenticity of the presented MRTD’s chip. OE.Prot_Logical_MRTD_CA Aditionally to the OE.Prot_Logical_MRTD, the inspection system prevents eavesdropping to their communication with the TOE before secure messaging is successfully established based on the Chip Authentication Protocol. Application note The Inspection Systems follow the order (i) running the Basic Access Control Protocol, (ii) reading and verifying only those parts of the logical MRTD that are necessary to know for the Chip Authentication Mechanism (i.e. Document Security Object and Chip Authentication Public Key), (iii) running the Chip Authentication Protocol, and (iv) reading and verifying the less-sensitive data of the logical MRTD after Chip Authentication. The supposed sequence has the advantage that the less-sensitive data are protected by secure messaging with cryptographic keys based on the Chip Authentication Protocol which quality is under control of the TOE. The inspection system will prevent additionally eavesdropping to their communication with the TOE before secure messaging is successfully established based on the Chip Authentication Protocol. Note that reading the less sensitive data directly after Basic Access Control Mechanism is allowed and is not assumed as threat in this PP. But the TOE ensures that reading of sensitive data is possible after successful Chip Authentication. 6.2.3 OE for AA OE.Exam_MRTD_AA Aditionally to the OE.Exam_MRTD, the inspection systems perform the Active Authentication protocol to verify the Authenticity of the presented MRTD’s chip. OE.Prot_Logical_MRTD_AA Aditionally to the OE.Prot_Logical_MRTD, the inspection system prevents eavesdropping to their communication with the TOE before secure messaging is successfully established based on the Active Authentication Protocol. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 49 | 80 OE.Activ_Auth_Verif In addition to the verification by passive authentication, the inspection systems may use the verification by Active Authentication, which offers a stronger guaranty of the authenticity of the MRTD.

LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 65 | 80 9 TOE Summary Specification 9.1 TOE Summary Access Control in reading This function controls access to read functions and enforces the security policy for data retrieval. Prior to any data retrieval, it authenticates the actor trying to access the data, and checks the access conditions are fulfilled as well as the life cycle state. It ensures that at any time, the following keys are never readable: BAC keys Chip Authentication keys, Active Authentication private key Personalization Agent keys MSK and LSK It controls access to the CPLC data as well: It ensures the CPLC data can be read during the personalization phase It ensures it cannot be readable in free mode at the end of the personalization step. Regarding the file structure: In the operational use: The terminal can read user data, the Document Security Object, EF.COM only after BAC authentication and through a valid secure channel. In the personalization phase: The Personalization Agent can read all the data stored in the TOE after it is authenticated by the TOE (using its authentication keys). It ensures as well that no other part of the memory can be accessed at anytime Access Control in writing This function controls access to write functions (in EEPROM) and enforces the security policy for data writing. Prior to any data update, it authenticates the actor, and checks the access conditions are fulfilled as well as the life cycle state. It ensures as well the CPLC data cannot be written anymore once the TOE is personalized. Regarding the file structure: In the operational use: It is not possible to create any files (system or data files). Furthermore, it is not possible to update any system files. However the application data is still accessed internally by the application for its own needs. In the personalization phase: The Personalization Agent can create and write through a valid secure channel all the data files it needs after it is authenticated by the TOE (using its authentication keys. Active Authentication This security functionality ensures the Active Authentication is performed as described in [49]. (if it is activated by the personnalizer). BAC mechanism This security functionality ensures the BAC is correctly performed. It can only be performed once the TOE is personalized with the symmetric BAC keys the Personalization Agent loaded beforehand during the personalization phase. Furthermore, this security functionality ensures the session keys are destroyed at the end of each BAC session. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 66 | 80 Chip Authentication This security functionality ensures the Chip Authentication is performed as described. It could be used as an alternative of Active Authentication to reinforce the Authentication of the Chip. It differs from an EAC not performing the Terminal Authentication. Personalization This security functionality ensures the TOE, when delivered to the Personnalization Agent, demands an authentication prior to any data exchange. This authentication is based on a symmetric Authentication mechanism based on a Triple DES or AES algorithm. This TSF can use a Secure Messaging described in the TSF Secure Messaging. Physical protection This security functionality protects the TOE against physical attacks. Prepersonalization This security functionality ensures the TOE, when delivered to the Prepersonalization Agent, demands an authentication prior to any data exchange. This authentication is based on a symmetric Authentication mechanism based on a Triple DES or AES algorithm. This function is in charge of pre-initializing the product. This TSF can use a Secure Messaging described in the TSF Secure Messaging. Safe state management This security functionalities ensures that the TOE gets back to a secure state when • an integrity error is detected by F.SELFTESTS • a tearing occurs (during a copy of data in EEPROM) This security functionality ensures that such a case occurs, the TOE is either switched in the state "kill card" or becomes mute. Secure Messaging This security functionality ensures the confidentiality, authenticity & integrity of the communication between the TOE and the IFD. After a successful BAC authentication, a secure channel is established based on Triple DES algorithm, and after a successful Chip Authentication, a secure channel is established based on Triple DES/AES algorithms. This security functionality ensures No commands were inserted, modified nor deleted within the data flow The data exchanged remain confidential If an error occurs in the secure messaging layer, the session keys are destroyed. This Secure Messaging can be combined with the Active Authentication. This TSF can provide a GP Secure Messaging (SCP02 or SCP03) for the Prepersonalization or Personalization. Self tests The TOE performs self tests to verify the integrity on the TSF data: • At reset LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 67 | 80 9.1.1 Security functional requirements analysis FAU_SAS.1 FCS_CKM.1 FCS_CKM.4 FCS_COP.1/SHA FCS_COP.1/ENC FCS_COP.1/AUTH FCS_COP.1/MAC FCS_RND.1 FIA_AFL.1 FIA_UID.1 FIA_UAU.1 FIA_UAU.4 FIA_UAU.5 FIA_UAU.6 FDP_ACC.1 FDP_ACF.1 FDP_UCT.1 FDP_UIT.1 FMT_SMF.1 FMT_SMR.1 FMT_LIM.1 FMT_LIM.2 FMT_MTD.1/INI_ENA FMT_MTD.1/INI_DIS FMT_MTD.1/KEY_WRITE FMT_MTD.1/KEY_READ FPT_EMS.1 FPT_FLS.1 FPT_TST.1 FPT_PHP.3 Access Control in reading X X X X X X X X X X X Access Control in writing X X X X Active Authentication X X X X X X X X X BAC mechanism X X X X X X X X X X X X X X X X Chip Authentication Personalization X X X X X X Physical protection X X X X Prepersonalization X X X X X X X X X Safe state management X X X X X X Secure Messaging X X X X X X X X X X Self tests X X Table 23 - Link between SFR from BAC PP and TSF LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 68 | 80 Table 24 - Link between SFR for AA and TSF FCS_CKM.1/CA FCS_COP.1/CA FDP_ITC.1/CA FIA_UID.1/CA FIA_UAU.1/CA FIA_UAU.5/CA FIA_UAU.6/CA FIA_API.1/CA FDP_UCT.1/CA FDP_UIT.1/CA FMT_MTD.1/CA_KEY_WRITE FMT_MTD.1/CA_KEY_READ Access Control in reading Access Control in writing Active Authentication BAC mechanism Chip Authentication X X X X X X X X X X X X Personalization X Physical protection Prepersonalizatio n FCS_COP.1/AA FDP_DAU.1/AA FDP_ITC.1/AA FMT_MOF.1/AA FMT_MTD.1/AA_KEY_WRITE FMT_MTD.1/AA_KEY_READ Access Control in reading X Access Control in writing X X X Active Authentication X X X X X X BAC mechanism Personalization Physical protection Prepersonalization Safe state management Secure Messaging Self tests LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 69 | 80 Safe state management Secure Messaging Self tests Table 25 : Link between SFR for CA and TSF LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 70 | 80 10 TOE Rationales Security Objectives rationale 10.1Threats and Security Objectives T.Chip_ID 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.

The examination of the presented MRTD passport book according to OE.Exam_MRTD "Examination of the MRTD passport book", OE.Exam_MRTD_CA and OE.Exam_MRTD_AA 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". T.Abuse-Func 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. T.Information_Leakage LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 71 | 80 The threat T.Information_Leakage "Information Leakage from MRTD’s chip" is typical for integrated circuits like smart cards under direct attack with high attack potential. The protection of the TOE against this threat is addressed by the directly related security objective OT.Prot_Inf_Leak "Protection against Information Leakage". T.Phys-Tamper The threat T.Phys-Tamper "Physical Tampering" is typical for integrated circuits like smart cards under direct attack with high attack potential. The protection of the TOE against this threat is addressed by the directly related security objective OT.Prot_Phys-Tamper "Protection against Physical Tampering". T.Malfunction The threat T.Malfunction "Malfunction due to Environmental Stress" is typical for integrated circuits like smart cards under direct attack with high attack potential. The protection of the TOE against this threat is addressed by the directly related security objective OT.Prot_Malfunction "Protection against Malfunctions". T.Counterfeit The threat T.Counterfeit "MRTD's chip" addresses the attack of unauthorized copy or reproduction of the genuine MRTD chip. This attack is thwarted by Active Authentication proving the authenticity of the chip as required by OT.AA_Proof and OT_Data_Int_AA using a authentication key pair to be generated by the issuing State or Organization. The Public Active Authentication Key has to be written into EF.DG15 and signed by means of Documents Security Objects, then . It is also covered by the Chip Authentication protocol OT.CA_Proof and OT_Data_Int_CA which is an alternative to the Active Authentication. The Public Chip Authentication Key has to be written into EF.DG14 and signed by means of Documents Security Objects as demanded by OE.Auth_Key_MRTD "MRTD Authentication Key". According to OE.Exam_MRTD_CA “Examination of the MRTD passport book” the General Inspection system has to perform the Chip Authentication Protocol to verify the authenticity of the MRTD’s chip. OE.Activ_Auth_Verif covers also this threat enabling the possibility of performing an Active Authentication which reinforce the security associated to the communication. 10.2Organisational Security Policies P.Personalization 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".

For ease reading some requirements are merged. 10.5.1 Rationale Security requirements and security objectives OT.AC_Pers The security objective OT.AC_Pers "Access Control for Personalization of logical MRTD" addresses the access control for the personalization of the MRTD, which consists in the writing of the logical MRTD data. The write access to the logical MRTD data are defined by 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 SFR FIA_UAU.4/BAC and FIA_UAU.5/BAC. 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 key or for reasons of interoperability with the [49] by] is authenticated using the symmetric authentication mechanism (FCS_COP.1/AUTH). Note symmetric authentication mechanism is used for interoperability with the [49]. In case of using the BAC mechanism 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. FMT_SMR.1 lists the roles (including Personalization Agent) and FMT_SMF.1 lists the TSF management functions (including Personalization) setting the Document Basic Access Keys according to FMT_MTD.1/KEY_WRITE as authentication reference data. FMT_MTD.1/KEY_READ prevents read access to the secret key of the Personalization Agent Keys and ensure together with FCS_CKM.4, FPT_EMS.1, FPT_FLS.1 and FPT_PHP.3 the confidentially of these keys. OT.Data_Int 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 FDP_ACC.1 and FDP_ACF.1 in the same way: 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). FMT_SMR.1 lists the roles (including Personalization Agent) and 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/BAC, FIA_UAU.5/BAC using the cryptographic operations defined of FCS_COP.1/*. Note that for interoperability reasons with the [49] Personalization Agent authentication is performed through 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 b means of the BAC mechanism. 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. 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. LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 75 | 80 OT.Data_Conf 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. 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). FMT_SMR.1 lists the roles (including Personalization Agent and Basic Inspection System) and FMT_SMF.1 lists the TSF management functions (including Personalization for the key management for the Document Basic Access Keys). FIA_UAU.4 prevents reuse of authentication data to strengthen the authentication of the user. 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, 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. 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. FCS_CKM.1, FCS_CKM.4, FCS_COP.1/SHA and FCS_RND.1 establish the key management for the secure messaging keys. 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 FIA_UAU.5 requires the Personalization Agent to use the Basic Access Control Authentication Mechanism or secure messaging. OT.Identification 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 FAU_SAS.1. Furthermore, the TOE shall identify itself only to a successful authenticated Basic Inspection System in Phase 4 "Operational Use". FMT_MTD.1/INI_ENA allows only the Manufacturer to write Initialization Data and Pre-personalization Data (including the Personalization Agent key). 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. 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. OT.Prot_Abuse-Func The security objective OT.Prot_Abuse-Func "Protection against Abuse of Functionality" is ensured by 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. OT.Prot_Inf_Leak 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 FPT_EMS.1, by forcing a malfunction of the TOE, which is addressed by FPT_FLS.1 and FPT_TST.1, and/or by a physical manipulation of the TOE, which is addressed by FPT_PHP.3. OT.Prot_Phys-Tamper LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 76 | 80 The security objective OT.Prot_Phys-Tamper "Protection against Physical Tampering" is covered by FPT_PHP.3. OT.Prot_Malfunction The security objective OT.Prot_Malfunction "Protection against Malfunctions" is covered by (i) 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) FPT_FLS.1 which requires a secure state in case of detected failure or operating conditions possibly causing a malfunction. OT.AA_Proof The security objective OT.AA_Proof is ensured by the Active Authentication Protocol activated by FMT_MOF.1/AA and provided by FDP_DAU.1/AA, FDP_ITC.1/AA proving the identity and authenticity of the TOE. The Active Authentication relies on FCS_COP.1/AA and FCS_RND.1. It is performed using a TOE internally stored confidential private key as required by FMT_MTD.1/AA_KEY_WRITE and FMT_MTD.1/AA_KEY_READ. OT.Data_Int_AA The security objective OT.AA_Proof is ensured by the Active Authentication Protocol activated by FMT_MOF.1/AA and provided by FDP_DAU.1/AA and FDP_ITC.1/AA proving the identity and authenticity of the TOE. OT.CA_Proof The security objective OT.CA_Proof is ensured by the Chip Authentication Protocol provided by FCS_COP.1/CA (for the derivation of the new session keys), FIA_UID.1/CA (for user to be successfully identified before allowing any other TSF-mediated actions on behalf of that user), FIA_UAU.1/CA (for user to be successfully authenticated before allowing any other TSF-mediated actions on behalf of that user), FDP_ITC.1/CA (for enforcing Chip Authentication Access Control SFP when importing user data, controlled under the SFP, from outside of the TOE), FIA_UAU.5/CA(for secure messaging and symmetric authentication), FIA_UAU.6/CA(for re- authenticating the user), FDP_UCT.1/CA and FDP_UIT.1/CA (for enforcing Access control SFP from unauthorised disclosure) and FIA_API.1/CA (for providing chip authentication protocol). The Chip Authentication relies on FCS_CKM.1/CA(for the generation of shared secret), for the key session establishment. Session keys are securely erased by FCS_CKM.4 in case of a bad SM, a card reset or a new Select. It is performed using a TOE internally stored confidential private key as required by FMT_MTD.1/CA_KEY_WRITE and FMT_MTD.1/CA_KEY_READ. OT.Data_Int_CA The security objective OT.Data_Int_CA is ensured by the Chip Authentication Protocol that constructs a trusted channel through the following SFR FIA_UID.1/CA (for user to be successfully identified before allowing any other TSF-mediated actions on behalf of that user), FIA_UAU.1/CA (for user to be successfully authenticated before allowing any other TSF-mediated actions on behalf of that user), FDP_ITC.1/CA (for enforcing Chip Authentication Access Control SFP when importing user data, controlled under the SFP, from outside of the TOE), FIA_UAU.5/CA(for secure messaging and symmetric authentication), FIA_UAU.6/CA(for re-authenticating the user), FDP_UCT.1/CA and FDP_UIT.1/CA (for enforcing Access control SFP from unauthorised disclosure) and FIA_API.1/CA (for providing chip authentication protocol). 10.5.2 Matrix Security requirements and security objectives SO SFR LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 77 | 80 SO SFR OT.AC_Pers FDP_ACC.1, FDP_ACF.1, FIA_UAU.4/BAC, FIA_UAU.5/BAC, FCS_CKM.1, FCS_COP.1/SHA, FCS_RND.1, FCS_COP.1/ENC, FCS_COP.1/MAC, FCS_COP.1/AUTH, FIA_UAU.6, FDP_UCT.1, FDP_UIT.1, FMT_SMF.1, FMT_SMR.1, FMT_MTD.1/KEY_WRITE, FMT_MTD.1/KEY_READ, FCS_CKM.4, FPT_EMS.1, FPT_PHP.3, FPT_FLS.1 OT.Data_Int FDP_ACC.1, FDP_ACF.1, FMT_SMR.1, FMT_SMF.1, FIA_UAU.4, FIA_UAU.5, FIA_UAU.6, FCS_COP.1/ENC, FCS_COP.1/MAC, FCS_COP.1/AUTH, FDP_UCT.1, FDP_UIT.1, FCS_CKM.1, FCS_COP.1/SHA, FCS_RND.1, FMT_MTD.1/KEY_WRITE, FMT_MTD.1/KEY_READ, FIA_UAU.4/BAC, FIA_UAU.5/BAC OT.Data_Conf FIA_UID.1, FIA_UAU.1, FIA_AFL.1, FDP_ACC.1, FDP_ACF.1, FMT_SMR.1, FMT_SMF.1, FIA_UAU.4, FIA_UAU.5, FIA_UAU.6, FCS_COP.1/ENC, FCS_COP.1/MAC, FDP_UCT.1, FDP_UIT.1, FCS_CKM.1, FCS_CKM.4, FCS_COP.1/SHA, FCS_RND.1, FMT_MTD.1/KEY_WRITE, FMT_MTD.1/KEY_READ OT.Identification FAU_SAS.1, FMT_MTD.1/INI_ENA, FMT_MTD.1/INI_DIS, FIA_UID.1, FIA_UAU.1, FIA_AFL.1 OT.Prot_Abuse- Func FMT_LIM.1, FMT_LIM.2 OT.Prot_Inf_Leak FPT_EMS.1, FPT_FLS.1, FPT_TST.1, FPT_PHP.3 OT.Prot_Phys- Tamper FPT_PHP.3 OT.Prot_Malfunction FPT_TST.1, FPT_FLS.1 OT.AA_Proof FMT_MOF.1/AA, FDP_DAU.1/AA, FCS_COP.1/AA, FCS_RND.1, FMT_MTD.1/AA_KEY_WRITE, FMT_MTD.1/AA_KEY_READ, FDP_ITC.1/AA OT.Data_Int_AA FMT_MOF.1/AA, FDP_DAU.1/AA, FDP_ITC.1/AA OT.CA_Proof FCS_COP.1/CA, FIA_UID.1/CA, FIA_UAU.1/CA, FIA_UAU.5/CA, FIA_UAU.6/CA, FDP_UCT.1/CA, FDP_UIT.1/CA, FIA_API.1/CA, FCS_CKM.1/CA, FMT_MTD.1/CA_KEY_WRITE, FMT_MTD.1/CA_KEY_READ, OT.Data_Int_CA FIA_UID.1/CA, FIA_UAU.1/CA, FIA_UAU.5/CA, FIA_UAU.6/CA, FDP_UCT.1/CA, FDP_UIT.1/CA, FIA_API.1/CA, FDP_ITC.1/CA Table 29: Security Requirements and Security Objectives Matrix 10.5.3 Dependencies justification SFRs Requirements CC Dependencies Satisfied Dependencies FAU_SAS.1 No dependencies FCS_CKM.1 (FCS_CKM.2 or FCS_COP.1) and (FCS_CKM.4) FCS_CKM.4, FCS_COP.1/ENC, FCS_COP.1/MAC FCS_CKM.4 (FCS_CKM.1 or FDP_ITC.1 or FDP_ITC.2) FCS_CKM.1 FCS_COP.1/SHA (FCS_CKM.1 or FDP_ITC.1 or FDP_ITC.2) and (FCS_CKM.4) FCS_CKM.4 See justification FCS_COP.1/ENC (FCS_CKM.1 or FDP_ITC.1 or FDP_ITC.2) and (FCS_CKM.4) FCS_CKM.1, FCS_CKM.4 FCS_COP.1/AUTH (FCS_CKM.1 or FDP_ITC.1 or FDP_ITC.2) and (FCS_CKM.4) See justification FCS_COP.1/MAC (FCS_CKM.1 or FDP_ITC.1 or FDP_ITC.2) and (FCS_CKM.4) FCS_CKM.1, FCS_CKM.4 FCS_RND.1 No dependencies FIA_AFL.1 (FIA_UAU.1) FIA_UAU.1 FIA_UID.1 No dependencies FIA_UAU.1 (FIA_UID.1) FIA_UID.1 LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 78 | 80 Requirements CC Dependencies Satisfied Dependencies FIA_UAU.4 No dependencies FIA_UAU.5 No dependencies FIA_UAU.6 No dependencies FDP_ACC.1 (FDP_ACF.1) FDP_ACF.1 FDP_ACF.1 (FDP_ACC.1) and (FMT_MSA.3) FDP_ACC.1 See justification FDP_UCT.1 (FDP_ACC.1 or FDP_IFC.1) and (FTP_ITC.1 or FTP_TRP.1) FDP_ACC.1 See justification FDP_UIT.1 (FDP_ACC.1 or FDP_IFC.1) and (FTP_ITC.1 or FTP_TRP.1) FDP_ACC.1 See justification FMT_SMF.1 No dependencies FMT_SMR.1 (FIA_UID.1) FIA_UID.1 FMT_LIM.1 (FMT_LIM.2) FMT_LIM.2 FMT_LIM.2 (FMT_LIM.1) FMT_LIM.1 FMT_MTD.1/INI_ENA (FMT_SMF.1) and (FMT_SMR.1) FMT_SMF.1, FMT_SMR.1 FMT_MTD.1/INI_DIS (FMT_SMF.1) and (FMT_SMR.1) FMT_SMF.1, FMT_SMR.1 FMT_MTD.1/KEY_WRITE (FMT_SMF.1) and (FMT_SMR.1) FMT_SMF.1, FMT_SMR.1 FMT_MTD.1/KEY_READ (FMT_SMF.1) and (FMT_SMR.1) FMT_SMF.1, FMT_SMR.1 FPT_EMS.1 No dependencies FPT_FLS.1 No dependencies FPT_TST.1 No dependencies FPT_PHP.3 No dependencies Table 30 -

SFRs for additional CA SFR 10.5.3.1 Rationale for the exclusion of dependencies Dependency FCS_CKM.1 or FDP_ITC.1 or FDP_ITC.2 of FCS_COP.1/SHA is unsupported. The hash algorithm required by 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. The dependency FMT_MSA.3 of FDP_ACF.1, FDP_ITC.1/CA, FDP_ITC.1/AA is unsupported. The access control TSF according to FDP_ACF.1 uses security attributes which are defined during the personalization and are fixed over the whole life time of the TOE. No management of these security attribute (i.e. SFR FMT_MSA.1 and FMT_MSA.3) is necessary here. The dependency FDP_ITC.1 or FDP_ITC.2 of FCS_COP.1/AUTH is unsupported. FCS_COP.1/AUTH uses the symmetric Personalization 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. The dependency FCS_CKM.4 for FCS_COP.1/AUTH is not required since the key is permanently stored within the TOE, there is no need for key destruction. The dependency FTP_ITC.1 or FTP_TRP.1 of FDP_UCT.1 is unsupported. FDP_UCT.1 requires the use of 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. The dependency FTP_ITC.1 or FTP_TRP.1 of FDP_UIT.1 is unsupported. FDP_UIT.1 required the use of 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. The dependency FTP_ITC.1 of FDP_UCT.1/CA and FDP_UIT.1/CA is unsupported. There is no need for 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. 10.5.4 SARs dependencies Reqs CC Dependencies Satisfied Dependencies ADV_ARC.1 (ADV_FSP.1) and (ADV_TDS.1) ADV_FSP.4, ADV_TDS.3 ADV_FSP.4 (ADV_TDS.1) ADV_TDS.3 ADV_IMP.1 (ADV_TDS.3) and (ALC_TAT.1) ADV_TDS.3, ALC_TAT.1 ADV_TDS.3 (ADV_FSP.4) ADV_FSP.4 AGD_OPE.1 (ADV_FSP.1) ADV_FSP.4 AGD_PRE.1 No Dependencies ALC_CMC.4 (ALC_CMS.1) and (ALC_DVS.1) and (ALC_LCD.1) ALC_CMS.4, ALC_DVS.2, ALC_LCD.1 ALC_CMS.4 No Dependencies ALC_DEL.1 No Dependencies ALC_DVS.2 No Dependencies LDS V10.1 Applet in BAC Configuration With CA and AA Public Security Target 80 | 80 Reqs CC Dependencies Satisfied Dependencies ALC_LCD.1 No Dependencies ALC_TAT.1 (ADV_IMP.1) ADV_IMP.1 ASE_CCL.1 (ASE_ECD.1) and (ASE_INT.1) and (ASE_REQ.1) ASE_ECD.1, ASE_INT.1, ASE_REQ.2 ASE_ECD.1 No Dependencies ASE_INT.1 No Dependencies ASE_OBJ.2 (ASE_SPD.1) ASE_SPD.1 ASE_REQ.2 (ASE_ECD.1) and (ASE_OBJ.2) ASE_ECD.1, ASE_OBJ.2 ASE_SPD.1 No Dependencies ASE_TSS.1 (ADV_FSP.1) and (ASE_INT.1) and (ASE_REQ.1) ADV_FSP.4, ASE_INT.1, ASE_REQ.2 ATE_COV.2 (ADV_FSP.2) and (ATE_FUN.1) ADV_FSP.4, ATE_FUN.1 ATE_DPT.1 (ADV_ARC.1) and (ADV_TDS.2) and (ATE_FUN.1) ADV_ARC.1, ADV_TDS.3, ATE_FUN.1 ATE_FUN.1 (ATE_COV.1) ATE_COV.2 ATE_IND.2 (ADV_FSP.2) and (AGD_OPE.1) and (AGD_PRE.1) and (ATE_COV.1) and (ATE_FUN.1) ADV_FSP.4, AGD_OPE.1, AGD_PRE.1, ATE_COV.2, ATE_FUN.1 AVA_VAN.3 (ADV_ARC.1) and (ADV_FSP.4) and (ADV_IMP.1) and (ADV_TDS.3) and (AGD_OPE.1) and (AGD_PRE.1) and (ATE_DPT.1) ADV_ARC.1, ADV_FSP.4, ADV_IMP.1, ADV_TDS.3, AGD_OPE.1, AGD_PRE.1, ATE_DPT.1 Table 33 - SARs dependencies
