CONTROL – CC IDEAL CITIZ Security target identifier : SSE-00078620 TOE reference : Chip identifier : SB23YR80 revision B TOE Identifier IDEAL/ST23YR80/1.4.5 Administration guidance : 0000074722 - IDeal - AGD - Pre-Personalization Manual 0000074723 - IDeal - AGD - Personalization Manual User guidance : 0000074862 - IDeal - AGD - ICAO User Manual CC compliance : Version : 3.1 Assurance level : EAL4 augmented with ALC_DVS.2 and AVA_VAN.5. Chip certificate reference : DCSSI-2010/02 Protection Profile BSI-CC-PP-0056, VERSION 1.10 [R5] 1.2 GENERAL OVERVIEW OF THE TARGET OF EVALUATION (TOE) 1.2.1 TOE type The Target of Evaluation (TOE) is a chip programmed according to the Logical Data Structure (LDS) [R9] (i.e. the MRTD’s chip) and providing the advanced security methods Extended Access Control (EAC), chip authentication as defined in [R10] and/or Active Authentication as defined in the Technical reports of “ICAO Doc 9303” [R9] in addition to the Basic Access Control1 . The MRTD’s chip allows the authenticity of the travel document and the identity of its holder to be checked during a border control, with the support of an inspection system. The MRTD’s chips are intended to be inserted into the cover page of traditional passport booklets. They can be integrated into modules, inlay or datapage. The final product can be a passport, a plastic card etc… The Chip Authentication prevents data traces described in [R9] informative appendix 7, A7.3.3. The Chip Authentication is provided by the following steps: 1 This BAC feature is not covered by the current ST Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 7/85 Page 7/85 − − − − the inspection system communicates by means of secure messaging established by Basic Access Control, − − − − the inspection system reads and verifies by means of the Passive Authentication the authenticity of the MRTD’s Chip Authentication Public Key using the Document Security Object, − − − − the inspection system generates an ephemeral key pair, (iv) the TOE and the inspection system agree on two session keys for secure messaging in ENC_MAC mode according to the Diffie- Hellman Primitive and − − − − the inspection system verifies by means of received message authentication codes whether the MRTD’s chip was able or not to run this protocol properly (i.e. the TOE proves to be in possession of the Chip Authentication Private Key corresponding to the Chip Authentication Public Key used for derivation of the session keys). The Chip Authentication requires collaboration of the TOE and the TOE environment. 1.2.2 Usage and major security features of the TOE The MRTD’s chip enables: − − − − protection of integrity of the holder’s stored data: issuing state or organization, travel document number, expiration date, holder’s name, nationality, birth date, sex, holder’s face portrait, other optional data, additional biometric data and several other pieces of data for managing the security of the document, − − − − authentication between the travel document holder and the inspection system prior to any border control by the Basic Access Control mechanism2 , − − − − protection of integrity and confidentiality of data read by secure messaging, − − − − authentication of the genuine chip by the Active Authentication mechanism (optional), − − − − strong authentication of the chip and the inspection system prior to any biometric data retrieval by the Extended Access Control mechanism. In addition to the protection provided by the chip, 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. 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 organizational security measures (e.g. control of materials, personalization procedures)[R9]. These security measures include the binding of the MRTD’s chip to the passport book. The details of these features are specified in [R9] and [R10]. 2 This BAC feature is not covered by the current ST but will be evaluated in another ST, see §3.3.3. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 8/85 Page 8/85 1.3 TOE DESCRIPTION 1.3.1 TOE Boundary 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) [R9] and providing Basic Access Control and Extended Access Control according to the ICAO Doc 9303 [R9] and BSI TR-03110 [R10], respectively. The TOE may also provide Active Authentication according to [R9]. The TOE boundary encompasses: − − − − The ICAO application − − − − The Operating System − − − − The ST embedded crypto library : NesCrypt V3.0.0 − − − − The ST chip The TOE does not allow any additional applets loading during its operational use. 1.3.2 TOE architecture The TOE is embedding two applications: − − − − AIP Application, compliant with [R21], which performs the pre-personalization and the personalization operations of the CC IDeal Citiz. This application is not accessible once in Operational Use phase. − − − − The ICAO/EAC application, which is compliant with [R9]. The ICAO application may be instantiated several times. The TOE does not allow any additional applets loading during its operational use. The architecture of the CC IDeal Citiz is given in Figure 1.

Development phase: IC design, and embedded software development; b. Manufacturing phase: from IC manufacturing to booklet manufacturing, including patch loading, application creation and pre-personalization (loading the authentication key for the personalization agent); c. Personalization phase: loading of all data related to the MRTD holder; Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 11/85 Page 11/85 d. Operational use phase: MRTD used by the traveler at the border control. The user data can be read according to the security policy of the issuing State or Organization and can be used according to the security policy of the issuing State but they can never be modified. 2. a business view made of 7 steps, focusing more on the different trades and actors involved in smartcard business, and commonly used in protection profile related to smartcard such as [R7]. For example, the company in charge of IC manufacturing may be different from the one in charge of IC packaging, as well as from the one in charge of packaging, initialisation, pre- personalization, not considering all other actors involved in this phase: antenna supplier, booklet supplier. The definition of the content of each step and the associated supply chain vary from one provider to another and the picture is just indicative. Referring to the life-cycle, the evaluated product is the product that comes out of the IC manufacturing, test and possible pre-personalization operations (step 3). At this step, the product is already self-protected before delivery to step 4 and all steps after. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 12/85 Page 12/85 2 CONFORMANCE CLAIMS 2.1 CONFORMANCE WITH THE COMMON CRITERIA This Security Target claims conformance to: Part 1 of the Common Criteria, Version 3.1, Release 1, dated September 2006 (see [R1]) − − − − Part 2 of the Common Criteria, Version 3.1, Release 2, dated September 2007 (see [R2]), − − − − Part 3 of the Common Criteria, Version 3.1, Release 2, dated September 2007 (see [R3]), as follows − − − − Part 2 extended, − − − − Part 3 conformant. 2.2 CONFORMANCE WITH AN ASSURANCE PACKAGE The level of assurance targeted by this Security Target is EAL4, augmented by the following components defined in CC part 3 [R3]: − − − − ALC_DVS.2, − − − − AVA_VAN.5. 2.3 CONFORMANCE WITH A PROTECTION PROFILE 2.3.1 Protection Profile reference This Security Target claims strict conformance to the Protection Profile MRTD EAC [R5]. 2.3.2 Protection Profile Refinements No specific refinement was performed to the Protection Profile MRTD EAC [R5]. 2.3.3 Protection Profile Additions The following asset which is optional the PP MRTD EAC [R5] has been added explicitly:  Active Authentication Private Key This additional asset is marked in italics in this ST. The following assumptions have been added to the PP MRTD EAC [R5]:  A_Pers_Agent_Active_Auth  A_Insp_Sys_Active_Auth These additional assumptions are marked in italics in this ST. The following objective has been added to the PP MRTD EAC [R5]:  OT.Active_Auth_Proof Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 13/85 Page 13/85 This additional objective is marked in italics in this ST. The following objectives for the environment have been added to the PP MRTD EAC [R5]:  OE.Active_Auth_Key_MRTD  OE.Exam_MRTD_Active_Auth These additional objectives for the environment are marked in italics in this ST. The following requirements have been added to the PP MRTD EAC [R5]:  FCS_COP.1/SIG_GEN  FIA_API.1/AAP  FMT_MTD.1/AAPK Additional requirements are marked in italics in this ST. Assignments of the following requirements have been augmented compared to those of the PP MRTD EAC [R5]:  FMT_MTD.1/KEY_READ  FPT_EMSEC.1 Augmentations are marked in italics inside the SFRs. 2.3.4 Application notes Application notes from the PP MRTD EAC [R5] have been copied in this ST when relevant. Moreover, application notes dedicated to the TOE described in this ST have been stated in addition to the application notes of the PP MRTD EAC [R5]. Those additional application notes should be marked in italics. 2.3.5 Protection Profile Claims rationale The differences between this Security Target security objectives and requirements and those of PP MRTD EAC [R5], to which conformance is claimed, have been identified and justified in chapter 4 and in 6. They have been recalled in the previous section. The TOE type defined in this security target is exactly the same than the one defined in the PP MRTD EAC [R5]: an IC with embedded software, and the MRTD application conformant to ICAO [R9] and EAC [R10]. In the following, the statements of the security problem definition, the security objectives, and the security requirements are consistent with those of the PP MRTD EAC [R5]. The security problem definition presented in chapter 3 clearly shows the additions to the security problem statement of the PP MRTD EAC [R5]. The security objectives rationale presented in chapter 4.4 clearly identifies modifications and additions made to the rationale presented in the PP MRTD EAC [R5]. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 14/85 Page 14/85 All PP requirements have been shown to be satisfied in the extended set of requirements whose completeness, consistency and soundness has been argued in the rationale sections of the present document. 2.4 CONFORMANCE WITH THE CC SUPPORTING DOCUMENTS This security target address a smartcard TOE and therefore, the associated evaluation shall be performed in compliance with all CC mandatory supporting documents related to smartcard evaluations: 2.4.1 Application of Attack Potential to Smartcards This document [R11] shall be used instead of the CEM [R4] when calculating the attack potential of the successful attack performed during AVA_VAN analysis. This document impacts only the vulnerability analysis performed by the ITSEF, and is not detailed here. 2.4.2 Composite product evaluation for Smartcards and similar devices This document [R12] shall be used in addition to the CC part 3 [R3] and to the CEM [R4]. This document specifies the additional information to be provided by a developer, and the additional checks to be performed by the ITSEF when performing a “composite evaluation”. This is the case for the current TOE as the underlying IC SB23YR80 revision B is already evaluated and certified under the reference: :DCSSI-2010/0. Therefore, the following additional assurance requirements apply for this TOE: − − − − ASE_COMP.1 for the security target ; − − − − ALC_COMP.1 for the life cycle support ; − − − − ADV_COMP.1 for the development activity ; − − − − ATE_COMP.1 for the tests activity ; − − − − AVA_COMP.1 for the vulnerability assessment. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 15/85 Page 15/85 3 SECURITY PROBLEM DEFINITION 3.1 ASSETS The assets to be protected by the TOE include the following User Data on the MRTD’s chip. The codes of the assets are the one used in the document [R9] part 1, volume 2, section III: − − − − EF.DG1: document data (type, issuing state or organization, document number, date of expiry) and holder’s biographical data (name, nationality, date of birth, sex), − − − − Sensitivity: integrity, − − − − EF.DG2: Sensitive biometric reference data – face, − − − − Sensitivity: integrity, − − − − EF.DG3 : Sensitive biometric reference data - Fingerprints, − − − − Sensitivity: confidentiality, integrity, − − − − EF.DG4: Sensitive biometric reference data – Iris, − − − − Sensitivity: confidentiality, integrity, − − − − EF.DG5: Displayed Portrait, − − − − Sensitivity: integrity, − − − − EF.DG6 to EF.DG16: optional fields and additional holder and document data (among which Active the Authentication Public Key in EF.DG15 and the Chip Authentication Public Key in EF.DG14), − − − − Sensitivity: integrity. The assets to be protected by the TOE include the following security data embedded on the MRTD’s chip. The codes of the assets are the one used in the document [R9] part 1, volume 2, section III and [R10] appendix A.3.2.4 − − − − EF.COM: Common Data Elements, containing the version information and tag list, − − − − Sensitivity: integrity, − − − − EF.SOD: Document Security Object, containing data integrity and authenticity information, − − − − Sensitivity: integrity, A sensitive asset is the following more general one: − − − − Authenticity of the MRTD’s chip: The authenticity of the MRTD’s chip personalized by the issuing State or Organization for the MRTD holder is used by the traveler to prove his possession of a genuine MRTD. This means that all assets used for that purpose (active authentication private key KPrAA, chip authentication private key SKPICC…) have to be protected in terms of confidentiality and integrity. Due to interoperability reasons the ‘ICAO Doc 9303’ [R9] requires that Basic Inspection Systems must have access to logical MRTD data DG1, DG2, DG5 to DG16 and files EF.COM, EF.SOD. Therefore, considering the intrinsic resistance of BAC mechanism, these data shall be protected at a high level (AVA_VAN.5) in terms of integrity only. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 16/85 Page 16/85 3.2 SUBJECTS The following individuals and IT systems have access to the TOE: Manufacturer “Manufacturer” is the generic term for the IC Manufacturer producing the integrated circuit as well as for 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 (step 3 to step 5). In this Security Target, the TOE does not distinguish between the users “IC Manufacturer” and the “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: − − − − establishing the identity of the holder for the biographic data in the MRTD, − − − − 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), − − − − writing these data on the physical and logical MRTD for the holder as defined for global, international and national interoperability, − − − − writing the initial TSF data and − − − − signing the Document Security Object defined in [R9]. Country Verifying Certification Authority The Country Verifying Certification Authority (CVCA) enforces the privacy policy of the issuing Country or Organization with respect to the protection of sensitive biometric reference data stored in the MRTD. The CVCA represents the country-specific root of the PKI of Inspection Systems and creates the Document Verifier Certificates within this PKI. The updates of the public key of the CVCA are distributed in the form of Country Verifying CA Link-Certificates. Document Verifier The Document Verifier (DV) enforces the privacy policy of the receiving Country with respect to the protection of sensitive biometric reference data to be handled by the Extended Inspection Systems. The Document Verifier manages the authorization of the Extended Inspection Systems for the sensitive data of the MRTD in the limits provided by the issuing States or Organizations in the form of the Document Verifier Certificates. Terminal A terminal is any technical system communicating with the TOE through its interface. Inspection system (IS) A technical system used by the border control officer of the receiving State: Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 17/85 Page 17/85 − − − − examining an MRTD presented by the traveler and verifying its authenticity, − − − − verifying the traveler as the MRTD holder. The Basic Inspection System (BIS): − − − − contains a terminal for the communication with the MRTD’s chip, − − − − implements the terminals part of the Basic Access Control Mechanism, − − − − gets the authorization to read the logical MRTD under the Basic Access Control by optically 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 in addition the Chip Authentication Mechanism. The Extended Inspection System (EIS) in addition to the General Inspection System: − − − − implements the Terminal Authentication Protocol, − − − − 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 by the Inspection System Certificates. MRTD Holder The rightful holder of the MRTD for whom the issuing State or Organization personalized the MRTD. Traveler Person presenting the MRTD to the inspection system and claiming the identity of the MRTD holder. 3.3 THREATS 3.3.1 Attacker Threats may occur as a result of a threat agent trying: − − − − to manipulate the logical MRTD without authorization, − − − − to read sensitive biometric reference data (i.e. EF.DG3, EF.DG4), − − − − to forge a genuine MRTD. Application note 1: An impostor is attacking the inspection system as TOE IT environment independent on using a genuine, counterfeit or forged MRTD. Therefore the impostor may use results of successful attacks against the TOE but the attack itself is not relevant for the TOE. 3.3.2 Attack potential Individuals performing attacks have a high attack potential. They correspond to malicious persons possessing the skills of an expert. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 18/85 Page 18/85 3.3.3 Threats not included An attacker trying to identify and to trace the movement of the MRTD’s chip remotely (i.e. without knowing or optically reading the physical MRTD) is not considered by this Security Target since this can only be averted by the BAC mechanism using the “weak” Document Basic Access Keys. These threats are covered by [R6] through the threats T.CHIP_ID and T.Skimming. The same hold for the confidentiality of the user data EF.DG1, EF.DG2, EF.DG5 to EF.DG16 and of the security data EF.SOD and EF.COM. 3.3.4 Threats relative to the TOE in operation The TOE in collaboration with its IT environment shall avert the threats as specified below. T.Read_Sensitive_Data Read the sensitive biometric reference data An attacker with high attack potential knowing the Document Basic Access Keys is trying to gain the sensitive biometric reference data through the communication interface of the MRTD’s chip. The attack T.Read_Sensitive_Data is similar to the threat T.Skimming (cf. [R6]) in respect of the attack path (communication interface) and the motivation (to get data stored on the MRTD’s chip) but differs from those in the asset under the attack (sensitive biometric reference data vs. digital MRZ, digitized portrait and other data), the opportunity (i.e. knowing Document Basic Access Keys) and therefore the possible attack methods. Note, that the sensitive biometric reference data are stored only on the MRTD’s chip as private sensitive personal data whereas the MRZ data and the portrait are visually readable on the physical MRTD as well. T.Forgery Forgery of data on MRTD’s chip An attacker alters fraudulently the complete stored logical MRTD or any part of it including its security related data in order to deceive on an inspection system by means of the changed MRTD holder’s identity or biometric reference data. This threat comprises several attack scenarios of MRTD forgery. The attacker may alter the biographical data on the biographical data page of the passport book, in the printed MRZ and in the digital MRZ to claim another identity of the traveler. The attacker may alter the printed portrait and the digitized portrait to overcome the visual inspection of the inspection officer and the automated biometric authentication mechanism by face recognition. The attacker may alter the biometric reference data to defeat automated biometric authentication mechanism of the inspection system. The attacker may combine data groups of different logical MRTDs to create a new forged MRTD, e.g. the attacker writes the digitized portrait and optional biometric reference data of finger read from the logical MRTD of a traveler into an other 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 chip. T.Counterfeit MRTD’s chip Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 19/85 Page 19/85 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 traveler 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. The TOE shall also avert the threats as specified below: T.Abuse-Func Abuse of Functionality An attacker may use functions of the TOE which shall not be used in “TOE operational Use” phase in order − − − − to manipulate User Data, − − − − to manipulate (explore, bypass, deactivate or change) security features or functions of the TOE or − − − − 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. T.Information_Leakage Information Leakage from MRTD’s chip 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). T.Phys-Tamper Physical Tampering An attacker may perform physical probing of the MRTD’s chip in order − − − − to disclose TSF Data, or − − − − to disclose/reconstruct the MRTD’s chip Embedded Software. An attacker may physically modify the MRTD’s chip in order to − − − − modify security features or functions of the MRTD’s chip, − − − − modify security functions of the MRTD’s chip Embedded Software, Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 20/85 Page 20/85 − − − − modify User Data or, − − − − 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. T.Malfunction Malfunction due to Environmental Stress An attacker may cause a malfunction of TSF or of the MRTD’s chip Embedded Software by applying environmental stress in order to − − − − deactivate or modify security features or functions of the TOE or − − − − circumvent, deactivate or modify security functions of the MRTD’s chip Embedded Software. This may be achieved e.g. by operating the MRTD’s chip outside the normal operating conditions, exploiting errors in the MRTD’s chip Embedded Software or misusing administration function. To exploit these vulnerabilities an attacker needs information about the functional operation. 3.4 ORGANISATIONAL SECURITY POLICIES (OSP) The TOE shall comply with the following Organizational Security Policies (OSP) as security rules, procedures, practices, or guidelines imposed by an organization upon its operations. P.BAC-PP Fulfilment of the Basic Access Control Protection Profile The issuing States or Organizations ensures that successfully authenticated Basic Inspection Systems have read access to logical MRTD data DG1, DG2, DG5 to DG16 the ‘ICAO Doc 9303’ [R9] as well as to the data groups Common and Security Data.

Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 24/85 Page 24/85 4 SECURITY OBJECTIVES This chapter describes the security objectives for the TOE and the security objectives for the TOE environment. The security objectives for the TOE environment are separated into security objectives for the development and production environment and security objectives for the operational environment. 4.1 SECURITY OBJECTIVES FOR THE TOE This section describes the security objectives for the TOE addressing the aspects of identified threats to be countered by the TOE and organizational security policies to be met by the TOE. OT.AC_Pers Access Control for Personalization of logical MRTD The TOE must ensure that the logical MRTD data in EF.DG1 to EF.DG16, the Document security object according to LDS [R9] and the TSF data can be written by authorized Personalization Agents only. The logical MRTD data in EF.DG1 to EF.DG16 and the TSF data may be written only during and cannot be changed after its personalization. The Document security object can be updated by authorized Personalization Agents if data in the data groups EF.DG3 to EF.DG16 are added. Application note 3: The OT.AC_Pers implies that − − − − the data of the LDS groups written during personalization for MRTD holder (at least EF.DG1 and EF.DG2) can not be changed by write access after personalization, − − − − the Personalization Agents may : • add (fill) data into the LDS data groups not written yet, and • update and sign the Document Security Object accordingly. The support for adding data in the “Operational Use” phase is optional. OT.Data_Int Integrity of personal data The TOE must ensure the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. The TOE must ensure the integrity of the logical MRTD data during their transmission to the General Inspection System after Chip Authentication. OT.Sens_Data_Conf Confidentiality of sensitive biometric reference data The TOE must ensure the confidentiality of the sensitive biometric reference data (EF.DG3 and EF.DG4) by granting read access only to authorized Extended inspection systems. The authorization of the inspection system is drawn from the Inspection System Certificate used for the successful authentication and shall be a non-strict subset of the authorization defined in the Document Verifier Certificate in the certificate chain to the Country Verifier Certification Authority of the issuing State or Organization. The TOE must ensure the confidentiality of the logical MRTD data during their transmission to the Extended Inspection System. The confidentiality of the sensitive biometric reference data shall be protected against attacks with high attack potential. OT.Identification Identification and Authentication of the TOE Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 25/85 Page 25/85 The TOE must provide means to store IC Identification and Pre-Personalization Data in its non-volatile memory. The IC Identification Data must provide a unique identification of the IC during Phase 2 “Manufacturing” and Phase 3 “Personalization of the MRTD”. The storage of the Pre-Personalization data includes writing of the Personalization Agent Authentication key(s). OT.Chip_Auth_Proof Proof of MRTD’s chip authenticity The TOE must support the General 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 [R10]. The authenticity proof provided by MRTD’s chip shall be protected against attacks with high attack potential. Application note 4: The OT.Chip_Auth_Proof implies the MRTD’s chip to have − − − − a unique identity as given by the MRTD’s Document number, − − − − 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 − − − − the Chip Authentication Public Key (EF.DG14) in the LDS [R9] and − − − − the hash value of the Chip Authentication Public Key in the Document Security Object signed by the Document Signer. OT.Active_Auth_Proof Proof of MRTD’s chip authenticity by Active Authentication The TOE may support the Extended Inspection System to verify the identity and authenticity of the MRTD’s chip as issued by the identified issuing State or Organization by means of the Active Authentication as defined in [R9]. The following TOE security objectives address the protection provided by the MRTD’s chip independent of the TOE environment. OT.Prot_Abuse-Func Protection against Abuse of Functionality After delivery of the TOE to the MRTD Holder, the TOE must prevent the abuse of test and support functions that may be maliciously used to − − − − disclose critical User Data, − − − − manipulate critical User Data of the IC Embedded Software, − − − − manipulate Soft-coded IC Embedded Software or − − − − bypass, deactivate, change or explore security features or functions of the TOE. Details of the relevant attack scenarios depend, for instance, on the capabilities of the Test Features provided by the IC Dedicated Test Software which are not specified here. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 26/85 Page 26/85 OT.Prot_Inf_Leak Protection against Information Leakage The TOE must provide protection against disclosure of confidential TSF data stored and/or processed in the MRTD’s chip − − − − by measurement and analysis of the shape and amplitude of signals or the time between events found by measuring signals on the electromagnetic field, power consumption, clock, or I/O lines and − − − − by forcing a malfunction of the TOE and/or − − − − by a physical manipulation of the TOE. Application note 5: This objective pertains to measurements with subsequent complex signal processing due to normal operation of the TOE or operations enforced by an attacker. Details correspond to an analysis of attack scenarios which is not given here. OT.Prot_Phys-Tamper Protection against Physical Tampering The TOE must provide protection of the confidentiality and integrity of the User Data, the TSF Data, and the MRTD’s chip Embedded Software. This includes protection against attacks with high 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 prior − − − − reverse-engineering to understand the design and its properties and functions. OT.Prot_Malfunction Protection against Malfunctions The TOE must ensure its correct operation. The TOE must prevent its operation outside the normal operating conditions where reliability and secure operation has not been proven or tested. This is to prevent errors. The environmental conditions may include external energy (esp. electromagnetic) fields, voltage (on any contacts), clock frequency, or temperature. Application note 6: A malfunction of the TOE may also be caused using a direct interaction with elements on the chip surface. This is considered as being a manipulation (refer to the objective OT.Prot_Phys-Tamper) provided that detailed knowledge about the TOE’s internals. 4.2 SECURITY OBJECTIVES FOR THE DEVELOPMENT AND PRODUCTION ENVIRONMENT OE.MRTD_Manufact Protection of the MRTD Manufacturing Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 27/85 Page 27/85 Appropriate functionality testing of the TOE shall be used in step 4 to 6. During all manufacturing and test operations, security procedures shall be used through phases 4, 5 and 6 to maintain confidentiality and integrity of the TOE and its manufacturing and test data. OE.MRTD_ Delivery Protection of the MRTD delivery Procedures shall ensure protection of TOE material/information under delivery including the following objectives: − − − − 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 rejected TOE’s), − − − − traceability of TOE during delivery including the following parameters: • origin and shipment details, • reception, reception acknowledgement, • location material/information.

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. 4.3 SECURITY OBJECTIVES FOR THE OPERATIONAL ENVIRONMENT Issuing State or Organization The issuing State or Organization will implement the following security objectives of the TOE environment. OE.Personalization Personalization of logical MRTD The issuing State or Organization must ensure that the Personalization Agents acting on behalf of the issuing State or Organization − − − − establish the correct identity of the holder and create biographical data for the MRTD, − − − − 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 − − − − personalize the MRTD for the holder together with the defined physical and logical security measures to protect the confidentiality and integrity of these data. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 28/85 Page 28/85 OE.Pass_Auth_Sign Authentication of logical MRTD by Signature The issuing State or Organization must − − − − generate a cryptographic secure Country Signing CA Key Pair, − − − − ensure the secrecy of the Country Signing CA Private Key and sign Document Signer Certificates in a secure operational environment, and − − − − 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 − − − − generate a cryptographic secure Document Signer Key Pair and ensure the secrecy of the Document Signer Private Keys, − − − − sign Document Security Objects of genuine MRTD in a secure operational environment only and − − − − distribute the Certificate of the Document Signer Public Key to receiving States and Organizations. The digital signature in the Document Security Object EF.SOD relates to all data in the data in EF.DG1 to EF.DG16 if stored in the LDS according to [R9]. OE.Auth_Key_MRTD MRTD Authentication Key The issuing State or Organization has to establish the necessary public key infrastructure in order to − − − − generate the MRTD’s Chip Authentication Key Pair, − − − − sign and store the Chip Authentication Public Key in the Chip Authentication Public Key data in EF.DG14 and − − − − 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.Authoriz_Sens_Data Authorization for Use of Sensitive Biometric Reference data The issuing State or Organization has to establish the necessary public key infrastructure in order to limit the access to sensitive biometric reference data of MRTD’s holders to authorized receiving States or Organizations. The Country Verifying Certification Authority of the issuing State or Organization generates card verifiable Document Verifier Certificates for the authorized Document Verifier only. OE.BAC_PP Fulfillment of the Basic Access Control Protection Profile It has to be ensured by the issuing State or Organization, that the TOE is additionally successfully evaluated and certified in accordance with the ‘Common Criteria Protection Profile Machine Readable Travel Document with „ICAO Application", Basic Access Control’ [R6]. This is necessary to cover the BAC mechanism ensuring the confidentiality of standard user data and preventing the traceability of the MRTD data. Note that due to the differences within the assumed attack potential the addressed evaluation and certification is a technically separated process. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 29/85 Page 29/85 Receiving State or Organization The receiving State or Organization will implement the following security objectives of the TOE environment. OE.Exam_MRTD Examination of the MRTD passport book The inspection system of the receiving State or Organization must examine the MRTD presented by the traveler to verify its authenticity by means of the physical security measures and to detect any manipulation of the physical MRTD. The Basic Inspection System for global interoperability − − − − includes the Country Signing Public Key and the Document Signer Public Key of each issuing State or Organization, and − − − − implements the terminal part of the Basic Access Control [R9]. Additionally General Inspection Systems and Extended Inspection Systems perform the Chip Authentication Protocol to verify the Authenticity of the presented MRTD’s chip. OE.Active_Auth_Key_MRTD MRTD Active Authentication Key The issuing State or Organization may establish the necessary public key infrastructure in order to : − − − − generate the MRTD’s Active Authentication Key Pair, − − − − sign and store the Active Authentication Public Key in the Active Authentication Public Key data in EF.DG15 and 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 Active Authentication Public Key by means of he Document Security Object. OE.Exam_MRTD_Active_Auth Examination of the MRTD passport book using Active Authentication During examination of the MRTD presented by the traveler, the Extended Inspection Systems may perform the Active Authentication Protocol to verify the Authenticity of the presented MRTD’s chip. OE.Passive_Auth_Verif Verification by Passive Authentication The border control officer of the receiving State uses the inspection system to verify the traveler as MRTD holder. The inspection systems must have successfully verified the signature of Document Security Objects and the integrity data elements of the logical MRTD before they are used. The receiving States and Organizations must manage the Country Signing CA Public Key and the Document Signer Public Key maintaining their authenticity and availability in all inspection systems. OE.Prot_Logical_MRTD Protection of data from the logical MRTD The inspection system of the receiving State or Organization ensures the confidentiality and integrity of the data read from the logical MRTD. The inspection system will prevent eavesdropping to their Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 30/85 Page 30/85 communication with the TOE before secure messaging is successfully established based on the Chip Authentication Protocol. Application note 7: The figure 2.1 in [R10] supposes that the GIS and the EIS follow the order − − − − running the Basic Access Control Protocol, − − − − 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), − − − − running the Chip Authentication Protocol, and − − − − 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 and Terminal Authentication Protocol only. OE.Ext_Insp_Systems Authorization of Extended Inspection Systems The Document Verifier of receiving States or Organizations authorizes Extended Inspection Systems by creation of Inspection System Certificates for access to sensitive biometric reference data of the logical MRTD. The Extended Inspection System authenticates themselves to the MRTD’s chip for access to the sensitive biometric reference data with its private Terminal Authentication Key and its Inspection System Certificate. 4.4 RATIONALE 4.4.1 Coverage matrix The following table provides an overview for security objectives coverage: OT.AC_Pers OT.Data_Int OT.Sens_Data_Conf OT.Identification OT.Chip_Auth_Proof OT.Active_Auth_Proof OT.Prot_Abuse-Func OT.Prot_Inf_Leak OT.Prot_Phys-Tamper OT.Prot_Malfunction OE.MRTD_Manufact OE.MRTD_ Delivery OE.Personalization OE.Pass_Auth_Sign OE.Auth_Key_MRTD OE.Active_Auth_Key_MRTD OE.Authoriz_Sens_Data OE.BAC-PP OE.Exam_MRTD OE.Exam_MRTD_Active_Auth OE.Pass_Auth_Verif OE.Prot_Logical_MRTD OE.Ext_Insp_System T.Read_Sensitive_Data X X X Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 31/85 Page 31/85 OT.AC_Pers OT.Data_Int OT.Sens_Data_Conf OT.Identification OT.Chip_Auth_Proof OT.Active_Auth_Proof OT.Prot_Abuse-Func OT.Prot_Inf_Leak OT.Prot_Phys-Tamper OT.Prot_Malfunction OE.MRTD_Manufact OE.MRTD_ Delivery OE.Personalization OE.Pass_Auth_Sign OE.Auth_Key_MRTD OE.Active_Auth_Key_MRTD OE.Authoriz_Sens_Data OE.BAC-PP OE.Exam_MRTD OE.Exam_MRTD_Active_Auth OE.Pass_Auth_Verif OE.Prot_Logical_MRTD OE.Ext_Insp_System T.Forgery X X X X X X T.Counterfeit X X X X X X T.Abuse-Func X T.Information_Leakage X T.Phys-tamper X T.Malfunction X P.BAC-PP X P.Sensitive_Data X X X P.Manufact X P.Personalization X X X A.MRTD_Manufact X A.MRTD_Delivery X A.Pers_Agent X A.Pers_Agent_Active_Au th X A.Insp_Sys X X A.Insp_Sys_Active_Auth X A.Signature_PKI X X A.Auth_PKI X X Table 1: Security problem definition / Security objectives 4.4.2 Coverage of threats in the operational environment T.Read_Sensitive_Data The OSP P.Sensitive_Data “Privacy of sensitive biometric reference data” is fulfilled and the threat T.Read_Sensitive_Data “Read the sensitive biometric reference data” is countered by the TOE- objective OT.Sens_Data_Conf “Confidentiality of sensitive biometric reference data” requiring that read access to EF.DG3 and EF.DG4 (containing the sensitive biometric reference data) is only granted to authorized inspection systems. Furthermore it is required that the transmission of these data ensures the data’s confidentiality. The authorization bases on Document Verifier certificates issued by the issuing State or Organization as required by OE.Authoriz_Sens_Data “Authorization for use of sensitive biometric reference data”. The Document Verifier of the receiving State has to authorize Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 32/85 Page 32/85 Extended Inspection Systems by creating appropriate Inspection System certificates for access to the sensitive biometric reference data as demanded by OE.Ext_Insp_Systems “Authorization of Extended Inspection Systems”. T.Forgery The threat T.Forgery “Forgery of data on MRTD’s chip” addresses the fraudulent alteration of the complete stored logical MRTD or any part of it. The security objective OT.AC_Pers “Access Control for Personalization of logical MRTD“ requires the TOE to limit the write access for the logical MRTD to the trustworthy Personalization Agent (cf. OE.Personalization). The TOE will protect the integrity of the stored logical MRTD according the security objective OT.Data_Int “Integrity of personal data” and OT.Prot_Phys-Tamper “Protection against Physical Tampering”. The examination of the presented MRTD passport book according to OE.Exam_MRTD “Examination of the MRTD passport book” shall ensure that passport book does not contain a sensitive 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.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 chip an identification and authenticity proof required by OT.Chip_Auth_Proof “Proof of MRTD’s chip authentication” using a authentication key pair to be generated by the issuing State or Organization. The Public Chip Authentication Key has to be written into EF.DG14 and signed by means of Documents Security Objects as demanded by OE.Auth_Key_MRTD “MRTD Authentication Key”. According to OE.Exam_MRTD “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. This threat is also thwarted by chip identification and authenticity proof required by OT.Active_Auth_Proof “Proof of MRTD’s chip authentication by Active Authentication” 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 as demanded by OE.Active_Auth_Key_MRTD “MRTD Active Authentication Key”. According to OE.Exam_MRTD_Active_Auth “Examination of the MRTD passport book using Active Authentication”, the Extended Inspection system may perform the Active Authentication Protocol to verify the authenticity of the MRTD’s chip. T.Abuse-Func The threat T.Abuse-Func “Abuse of Functionality” addresses attacks of misusing MRTD’s functionality to disable or bypass the TSFs. The security objective for the TOE OT.Prot_Abuse-Func “Protection against abuse of functionality” ensures that the usage of functions which may not be used in the “operational Use” phase is effectively prevented. Therefore attacks intending to abuse functionality in Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 33/85 Page 33/85 order to disclose or manipulate critical (User) Data or to affect the TOE in such a way that security features or TOE’s functions may be bypassed, deactivated, changed or explored shall be effectively countered. T.Information_Leakage, T.Phys-Tamper, T.Malfunction The threats T.Information_Leakage “Information Leakage from MRTD’s chip”, T.Phys-Tamper “Physical Tampering” and T.Malfunction “Malfunction due to Environmental Stress” are typical for integrated circuits like smart cards under direct attack with high attack potential. The protection of the TOE against these threats is addressed by the directly related security objectives OT.Prot_Inf_Leak “Protection against Information Leakage”, OT.Prot_Phys-Tamper “Protection against Physical Tampering” and OT.Prot_Malfunction “Protection against Malfunctions”. 4.4.3 Coverage of organisational security policies P.BAC-PP The OSP P.BAC-PP is directly addressed by the OE.BAC-PP. P.Sensitive_Data See “T.Read_Sensitive_Data”. P.Manufact The OSP P.Manufact “Manufacturing of the MRTD’s chip” requires a unique identification of the IC by means of the Initialization Data and the writing of the Prepersonalization Data as being fulfilled by OT.Identification. P.Personalization The OSP P.Personalization “Personalization of the MRTD by issuing State or Organization only” addresses the: − − − − 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 − − − − the access control for the user data and TSF data as described by the security objective OT.AC_Pers “Access Control for Personalization of logical MRTD”. Note the manufacturer equips the TOE with the Personalization Agent Authentication key(s) according to OT.Identification “Identification and Authentication of the TOE”. The security objective OT.AC_Pers limits the management of TSF data and the management of TSF to the Personalization Agent.

Some of these components are defined in [R7], other components are defined in protection profile MRTD EAC [R5]. 5.1 DEFINITION OF THE FAMILY FAU_SAS To define the security functional requirements of the TOE a sensitive family (FAU_SAS) of the Class FAU (Security Audit) is defined here. This family describes the functional requirements for the storage of audit data. It has a more general approach than FAU_GEN, because it does not necessarily require the data to be generated by the TOE itself and because it does not give specific details of the content of the audit records. The family “Audit data storage (FAU_SAS)” is specified as follows. FAU_SAS Audit data storage Family behaviour This family defines functional requirements for the storage of audit data. Component levelling FAU_SAS.1 Requires the TOE to provide the possibility to store audit data. Management: FAU_SAS.1 There are no management activities foreseen. Audit: FAU_SAS.1 There are no actions defined to be auditable. FAU_SAS.1 Audit storage Hierarchical to: No other components. Dependencies: No dependencies. FAU_SAS.1.1 The TSF shall provide [assignment: authorized users] with the capability to store [assignment: list of audit information] in the audit records. FAU_SAS Audit data storage 1 Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 37/85 Page 37/85 5.2 DEFINITION OF THE FAMILY FCS_RND To define the IT security functional requirements of the TOE an additional family (FCS_RND) of the Class FCS (cryptographic support) is defined here. This family describes the functional requirements for random number generation used for cryptographic purposes. The component FCS_RND is not limited to generation of cryptographic keys unlike the component FCS_CKM.1. The similar component FIA_SOS.2 is intended for non-cryptographic use. The family “Generation of random numbers (FCS_RND)” is specified as follows. FCS_RND Generation of random numbers Family behaviour This family defines quality requirements for the generation of random numbers which are intended to be use for cryptographic purposes. Component leveling: FCS_RND.1 Generation of random numbers requires that random numbers meet a defined quality metric. Management: FCS_RND.1 There are no management activities foreseen. Audit: FCS_RND.1 There are no actions defined to be auditable. FCS_RND.1 Quality metric for random numbers Hierarchical to: No other components. Dependencies: No dependencies. FCS_RND.1.1 The TSF shall provide a mechanism to generate random numbers that meet [assignment: a defined quality metric]. 5.3 DEFINITION OF THE FAMILY FIA_API To describe the IT security functional requirements of the TOE a sensitive family (FIA_API) of the Class FIA (Identification and authentication) is defined here. This family describes the functional requirements FCS_RND Generation of random numbers 1 Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 38/85 Page 38/85 for the proof of the claimed identity for the authentication verification by an external entity where the other families of the class FIA address the verification of the identity of an external entity. Application note 8: The other families of the Class FIA describe only the authentication verification of users’ identity performed by the TOE and do not describe the functionality of the user to prove their identity. The following paragraph defines the family FIA_API in the style of the Common Criteria part 2 (cf. [3], chapter “Explicitly stated IT security requirements (APE_SRE)”) from a TOE point of view. FIA_API Authentication Proof of Identity Family behaviour This family defines functions provided by the TOE to prove their identity and to be verified by an external entity in the TOE IT environment. Component levelling FIA_API.1 Authentication Proof of Identity. Management: FIA_API.1 The following actions could be considered for the management functions in FMT: Management of authentication information used to prove the claimed identity. Audit: FIA_API.1 There are no actions defined to be auditable. FIA_API.1 Authentication Proof of Identity. Hierarchical to: No other components. Dependencies: No dependencies. FIA_API.1.1 The TSF shall provide a [assignment: authentication mechanism] to prove the identity of the [assignment: authorized user or role]. 5.4 DEFINITION OF THE FAMILY FMT_LIM The family FMT_LIM describes the functional requirements for the Test Features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE show that no other FIA_API Authentication Proof of Identity 1 Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 39/85 Page 39/85 class is appropriate to address the specific issues of preventing the abuse of functions by limiting the capabilities of the functions and by limiting their availability. The family “Limited capabilities and availability (FMT_LIM)” is specified as follows. FMT_LIM Limited capabilities and availability Family behaviour This family defines requirements that limit the capabilities and availability of functions in a combined manner. Note that FDP_ACF restricts the access to functions whereas the component Limited Capability of this family requires the functions themselves to be designed in a specific manner. Component levelling FMT_LIM.1 Limited capabilities requires that the TSF is built to provide only the capabilities (perform action, gather information) necessary for its genuine purpose. FMT_LIM.2 Limited availability requires that the TSF restrict the use of functions (refer to Limited capabilities (FMT_LIM.1)). This can be achieved, for instance, by removing or by disabling functions in a specific phase of the TOE’s life-cycle. Management: FMT_LIM.1, FMT_LIM.2 There are no management activities foreseen. Audit: FMT_LIM.1, FMT_LIM.2 There are no actions defined to be auditable. To define the IT security functional requirements of the TOE a sensitive family (FMT_LIM) of the Class FMT (Security Management) is defined here. This family describes the functional requirements for the Test Features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE show that no other class is appropriate to address the specific issues of preventing the abuse of functions by limiting the capabilities of the functions and by limiting their availability. The TOE Functional Requirement “Limited capabilities (FMT_LIM.1)” is specified as follows. FMT_LIM.1 Limited capabilities. FMT_LIM Limited capabilities and availability 2 1 Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 40/85 Page 40/85 Hierarchical to: No other components. Dependencies: FMT_LIM.2 Limited availability. FMT_LIM.1.1 The TSF shall be designed and implemented in a manner that limits its capabilities so that in conjunction with “Limited availability (FMT_LIM.2)” the following policy is enforced [assignment: Limited capability and availability policy]. The TOE Functional Requirement “Limited availability (FMT_LIM.2)” is specified as follows. FMT_LIM.2 Limited availability. Hierarchical to: No other components. Dependencies: FMT_LIM.1 Limited capabilities. FMT_LIM.2.1 The TSF shall be designed in a manner that limits its availability so that in conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced [assignment: Limited capability and availability policy]. Application note 9: The functional requirements FMT_LIM.1 and FMT_LIM.2 assume that there are two types of mechanisms (limited capabilities and limited availability) which together shall provide protection in order to enforce the policy. This also allows that − − − − the TSF is provided without restrictions in the product in its user environment but its capabilities are so limited that the policy is enforced or conversely − − − − the TSF is designed with test and support functionality that is removed from, or disabled in, the product prior to the Operational Use Phase. The combination of both requirements shall enforce the policy. 5.5 DEFINITION OF THE FAMILY FPT_EMSEC The sensitive family FPT_EMSEC (TOE Emanation) of the Class FPT (Protection of the TSF) is defined here to describe the IT security functional requirement of the TOE. The TOE shall prevent attacks against the TOE and other secret data where the attack is based on external observable physical phenomena of the TOE. Examples of such attacks are evaluation of TOE’s electromagnetic radiation, simple power analysis (SPA), differential power analysis (DPA), timing attacks, etc. This family describes the functional requirements for the limitation of intelligible emanations which are not directly addressed by any other component of CC part 2 [R2]. The family “TOE Emanation (FPT_EMSEC)” is specified as follows. FPT_EMSEC TOE emanation Family behaviour Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 41/85 Page 41/85 This family defines requirements to mitigate intelligible emanations. Component levelling FPT_EMSEC.1 TOE emanation has two constituents: FPT_EMSEC.1.1 Limit of Emissions requires to not emit intelligible emissions enabling access to TSF data or user data. FPT_EMSEC.1.2 Interface Emanation requires to not emit interface emanation enabling access to TSF data or user data. Management: FPT_EMSEC.1 There are no management activities foreseen. Audit: FPT_EMSEC.1 There are no actions defined to be auditable. FPT_EMSEC.1 TOE emanation Hierarchical to: No other components. Dependencies: No dependencies. FPT_EMSEC.1.1 The TOE shall not emit [assignment: types of emissions] in excess of [assignment: specified limits] enabling access to [assignment: list of types of TSF data] and [assignment: list of types of user data]. FPT_EMSEC.1.2 The TSF shall ensure [assignment: type of users] are unable to use the following interface [assignment: type of connection] to gain access to [assignment: list of types of TSF data] and [assignment: list of types of user data].

The users in role Personalization Agent identify themselves by means of selecting the authentication key. After personalization in the Phase 3 the Document Basic Access Keys, the Chip authentication data and Terminal Authentication 3 The BAC Authentication Protocol is included here as part of the Chip Authentication Protocol because it is a necessary condition to read the EF.DG14.

Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 51/85 Page 51/85 Assignment Identified authentication mechanism(s): (1) Terminal Authentication Protocol, (2) Authentication Mechanism based on Triple-DES Application note 21: The authentication mechanisms may use either a challenge freshly and randomly generated by the TOE to prevent reuse of a response generated by a terminal in a successful authentication attempt. The TOE shall meet the requirement “Multiple authentication mechanisms (FIA_UAU.5)” as specified below (Common Criteria Part 2). FIA_UAU.5 Multiple authentication mechanisms FIA_UAU.5.1 The TSF shall provide [assignment : list of multiple authentication mechanisms] to support user authentication. Assignment List of multiple authentication mechanisms: (1) Terminal Authentication Protocol, (2) Secure messaging in MAC-ENC mode, (3) Symmetric Authentication Mechanism based on Triple-DES FIA_UAU.5.2 The TSF shall authenticate any user’s claimed identity according to the [assignment : rules describing how the multiple authentication mechanisms provide authentication]. Assignment Rules describing how the multiple authentication mechanisms provide authentication: (1) The TOE accepts the authentication attempt as Personalization Agent by the Symmetric Authentication Mechanism with Personalization Agent Key during personalization phase of the product's life cycle (phase 3), (2) After run of the Chip Authentication Protocol the TOE accepts only received commands with correct message authentication code sent by means of secure messaging with key agreed with the terminal by means of the Chip Authentication Mechanism, (3) The TOE accepts the authentication attempt by means of the Terminal Authentication Protocol only if the terminal uses the public key presented during the Chip Authentication Protocol and the secure messaging established by the Chip Authentication Mechanism. Application note 22: Depending on the authentication methods used the Personalization Agent holds a key for the Symmetric Authentication Mechanism. The Basic Access Control Mechanism includes the secure messaging for all commands exchanged after successful authentication of the inspection system. The Personalization Agent may use Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 52/85 Page 52/85 Symmetric Authentication Mechanism without secure messaging mechanism as well if the personalization environment prevents eavesdropping to the communication between TOE and personalization terminal. The authentication of the personalization agent is only possible during phase 3 of the life-cycle, using symetric authentication mechanism. This can be considered as a refinement of the SFR FIA_UAU.5 of the PP. However, this refinement is more restrictive than the PP, increase the level off security and therefore, do not impact the conformity to the PP. The Basic Inspection System shall use the Basic Access Control Authentication Mechanism with the Document Basic Access Keys and the secure messaging after the mutual authentication. The General Inspection System shall use the secure messaging with the keys generated by the Chip Authentication Mechanism. The TOE shall meet the requirement “Re-authenticating (FIA_UAU.6)” as specified below (Common Criteria Part 2). FIA_UAU.6 Re-authenticating – Re-authenticating of Terminal by the TOE FIA_UAU.6.1 The TSF shall re-authenticate the user under the conditions [assignment : list of conditions under which re-authentication is required]. Assignment List of conditions under which re-authentication is required: (1) Each command sent to the TOE after successful run of the Chip Authentication Protocol shall be verified as being sent by the GIS. Application note 23: The Basic Access Control Mechanism and the Chip Authentication Protocol specified in [R9] include secure messaging for all commands exchanged after successful authentication of the Inspection System. The TOE checks by secure messaging in MAC_ENC mode each command based on Retail-MAC whether it was sent by the successfully authenticated terminal (see FCS_COP.1/MAC for further details). The TOE does not execute any command with incorrect message authentication code. Therefore the TOE re-authenticates the user for each received command and accept only those commands received from the previously authenticated user. The TOE shall meet the requirement “Authentication Proof of Identity (FIA_API.1)” as specified below (Common Criteria Part 2 extended). FIA_API.1/CAP Authentication Proof of Identity - MRTD Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 53/85 Page 53/85 FIA_API.1.1 / CAP The TSF shall provide a [assignment : authentication mechanism] to prove the identity of the [assignment : authorized user or rule]. Assignment Authentication mechanism: Chip Authentication Protocol according to [R10] Authorized user or rule : TOE Application note 24: This SFR requires the TOE to implement the Chip Authentication Mechanism specified in [R10]. The TOE and the terminal generate a shared secret using the Diffie-Hellman Protocol (DH or EC-DH) and two session keys for secure messaging in ENC_MAC mode according to [R9], normative appendix 5, A5.1. The terminal verifies by means of secure messaging whether the MRTD’s chip was able or not to run his protocol properly using its Chip Authentication Private Key corresponding to the Chip Authentication Key (EF.DG14). FIA_API.1/AAP Authentication Proof of Identity – MRTD using Active Authentication FIA_API.1.1 / AAP The TSF shall provide a [assignment : authentication mechanism] to prove the identity of the [assignment : authorized user or rule]. Assignment Authentication mechanism: Active Authentication Protocol according to [R9] Authorized user or rule : TOE Application note 25: The TOE may implement the Active Authentication Mechanism specified in [5]. The terminal randomly generates a challenge, then the MRTD chip digitally signs this challenge using RSA and finally the terminal verifies that the returned signature is correct. 6.2.4 Class FDP User Data Protection 6.2.4.1 ACCESS CONTROL POLICY (FDP_ACC) The TOE shall meet the requirement “Subset access control (FDP_ACC.1)” as specified below (Common Criteria Part 2). FDP_ACC.1 Subset access control FDP_ACC.1.1 The TSF shall enforce the [assignment : access control SFP] on [assignment: list of subjects, objects and operations among subjects and objects covered by the SFP]. Assignment Access control SFP : Access Control SFP List of subject, objects and operations among subjects and objects covered Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 54/85 Page 54/85 by the SFP : terminals gaining write, read and modification access to data in the EF.COM, EF.SOD, EF.DG1 to EF.DG16 of the logical MRTD 6.2.4.2 ACCESS CONTROL FUNCTIONS (FDP_ACF) The TOE shall meet the requirement “Security attribute based access control (FDP_ACF.1)” as specified below (Common Criteria Part 2). FDP_ACF.1 Security attribute based access control FDP_ACF.1.1 The TSF shall enforce the [assignment : access control SFP] to objects based on the following : [assignment : list of subjects and objects controlled under the indicated SFP, and, for each, the SFP-relevant security attributes, or named groups of SFP-relevant security attributes]. Assignment Access control SFP : Access Control SFP List of subjects and objects controlled under the indicated SFP, and, for each, the SFP-relevant security attributes, or named groups of SFP-relevant security attributes: (1) Subjects : a) Personalization Agent, b) Extended Inspection System c) Terminal, (2) Objects : d) data EF.DG1, EF.DG2 and EF.DG5 to EF.DG16 of the logical MRTD, e) data EF.DG3 and EF.DG4 of the logical MRTD, f) Data in EF.COM, g) Data in EF.SOD. Security attributes : h) Authentication status of terminals, i) Terminal authorization. FDP_ACF.1.2 The TSF shall enforce the following rules to determine if an operation among controlled subjects and controlled objects is allowed: [assignment : rules governing access among controlled subjects and controlled objects using controlled operations on controlled objects]. Assignment Rules governing access among controlled subjects and controlled objects using controlled operations on controlled objects : (1) the successfully authenticated Personalization Agent is allowed Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 55/85 Page 55/85 to write and to read the data of the EF.COM, EF.SOD, EF.DG1 to EF.DG16 of the logical MRTD, (2) the successfully authenticated Extended Inspection System with the Read access to DG 3 (Fingerprint) granted by the relative certificate holder authorization is allowed to read the data in EF.DG3 of the logical MRTD, (3) the successfully authenticated Extended Inspection System with the Read access to DG 4 (Iris) granted by the relative certificate holder authorization is allowed to read the data in EF.DG4 of the logical MRTD. FDP_ACF.1.3 The TSF shall explicitly authorize access of subjects to objects based on the following sensitive rules: [assignment: rules, based on security attributes, that explicitly authorize access of subjects to objects]. Assignment Rules, based on security attributes, that explicitly authorize access of subjects to objects : none FDP_ACF.1.4 The TSF shall explicitly deny access of subjects to objects based on the rule: [assignment: rules, based on security attributes, that explicitly deny access of subjects to objects]. Assignment Rules, based on security attributes, that explicitly deny access of subjects to objects : (1) A terminal authenticated as CVCA is not allowed to read data in the EF.DG3, (2) A terminal authenticated as CVCA is not allowed to read data in the EF.DG4, (3) A terminal authenticated as DV is not allowed to read data in the EF.DG3, (4) A terminal authenticated as DV is not allowed to read data in the EF.DG4, (5) Any terminal is not allowed to modify any of the EF.DG1 to EF.DG16 of the logical MRTD, (6) Any terminal not being successfully authenticated as Extended Inspection System is not allowed to read any of the EF.DG3 to EF.DG4 of the logical MRTD. Application note 26: The relative certificate holder authorization encoded in the CVCA of the inspection system is defined in [R10], Annex A.5.1, table A.8. The TOE verifies the certificate chain established by the Country Verifying Certification Authority, the Document Verifier Certificate and the Inspection System Certificate (cf. FMT_MTD.3). The Terminal Authorization is the intersection of the Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 56/85 Page 56/85 Certificate Holder Authorization in the certificates of the Country Verifying Certification Authority, the Document Verifier Certificate and the Inspection System Certificate in a valid certificate chain. Application note 27: Note the BAC mechanism controls the read access of the EF.COM, EF.SOD, EF.DG1, EF.DG2, EF.DG5 to EF.DG16 of the logical MRTD. According to P.BAC-PP this security features of the MRTD are not subject of this Security Target. 6.2.4.3 INTER-TSF USER DATA CONFIDENTIALITY TRANSFER PROTECTION (FDP_UCT) The TOE shall meet the requirement “Basic data exchange confidentiality (FDP_UCT.1)” as specified below (Common Criteria Part 2). FDP_UCT.1 Basic data exchange confidentiality - MRTD FDP_UCT.1.1 The TSF shall enforce the [assignment : access control SFP(s) and/or information flow control SFP(s)] to be able to [selection : transmit, receive] user data in a manner protected from unauthorized disclosure after Chip Authentication. Assignment Access control SFP(s) and/or information flow control SFP(s): Access Control SFP Selection Transmit and receive 6.2.4.4 INTER-TSF USER DATA INTEGRITY TRANSFER PROTECTION (FDP_UIT) The TOE shall meet the requirement “Data exchange integrity (FDP_UIT.1)” as specified below (Common Criteria Part 2). FDP_UIT.1 Basic data exchange integrity - MRTD FDP_UIT.1.1 The TSF shall enforce the [assignment : access control SFP(s) and/or information flow control SFP(s)] to be able to [selection : transmit, receive] user data in a manner protected from [selection : modification, deletion, insertion, replay] errors after Chip Authentication. Assignment Access control SFP(s) and/or information flow control SFP(s): Access Control SFP Selection transmit and receive modification, deletion, insertion and replay FDP_UIT.1.2 The TSF shall be able to determine on receipt of user data, whether [selection : modification, deletion, insertion, replay] has occurred after Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 57/85 Page 57/85 Chip Authentication. Selection modification, deletion, insertion and replay Refinement: Note that the Access Control SFP (cf. FDP_ACF.1.2) allows the Extended Inspection System (as of [R9] and [R6]) to access the data EF.COM, EF.SOD, EF.DG1, EF.DG2 and EF.DG5 to EF.DG16 of the logical MRTD. Nevertheless there is explicitly no rule for preventing access to these data. More over their data integrity (cf. FDP_UIT.1) and confidentiality (cf. FDP_UCT.1) is ensured by the BAC mechanism being addressed and covered by [R6]. The fact that the BAC mechanism is not part of the Security Target in hand is addressed by the refinement “after Chip Authentication”. Application note 28: FDP_UCT.1 and FDP_UIT.1 require the protection of the User Data transmitted from the TOE to the terminal by secure messaging with encryption and message authentication codes after successful Chip Authentication to the General Inspection System. The authentication mechanism as part of Basic Access Control Mechanism and the Chip Authentication Protocol establish different key sets to be used for secure messaging (each set of keys for the encryption and the message authentication key). 6.2.5 Class FMT Security Management Application note 29: The SFR FMT_SMF.1 and FMT_SMR.1 provide basic requirements to the management of the TSF data. 6.2.5.1 SPECIFICATION OF MANAGEMENT FUNCTIONS (FMT_SMF) The TOE shall meet the requirement “Specification of Management Functions (FMT_SMF.1)” as specified below (Common Criteria Part 2). FMT_SMF.1 Specification of Management Functions FMT_SMF.1.1 The TSF shall be capable of performing the following security management functions [assignment : list of security management functions to be provided by the TSF]. Assignment List of security management functions to be provided by the TSF : (1) Initialization, (2) Personalization, (3) Configuration. Application note 30: The configuration capabilities of the TOE are available during the pre- personalization (initialization) and personalization phases. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 58/85 Page 58/85 6.2.5.2 SECURITY MANAGEMENT ROLES (FMT_SMR) The TOE shall meet the requirement “Security roles (FMT_SMR.1)” as specified below (Common Criteria Part 2). FMT_SMR.1 Security roles FMT_SMR.1.1 The TSF shall maintain the roles [assignment : the authorized identified roles]. Assignment The authorized identified roles: (1) Manufacturer, (2) Personalization Agent, (3) Country Verifying Certification Authority, (4) Document Verifier, (5) Domestic Extended Inspection System, (6) Foreign Extended Inspection System. FMT_SMR.1.2 The TSF shall be able to associate users with roles. Application note 31: Note that the MRTD also maintains the role Basic Inspection System due to a direct consequence of P.BAC-PP resp. OE.BAC-PP. Nevertheless this role is not explicitly listed in FMT_SMR.1.1, above since the TSF cannot maintain the role with respect to the assumed high attack potential due to the known weaknesses of the Document Basic Access Keys. 6.2.5.3 LIMITED CAPABILITIES AND AVAILABILITY (FMT_LIM) Application note 32: The SFR FMT_LIM.1 and FMT_LIM.2 address the management of the TSF and TSF data to prevent misuse of test features of the TOE over the life cycle phases. The TOE shall meet the requirement “Limited capabilities (FMT_LIM.1)” as specified below (Common Criteria Part 2 extended). FMT_LIM.1 Limited capabilities FMT_LIM.1.1 The TSF shall be designed in a manner that limits their capabilities so that in conjunction with “Limited availability (FMT_LIM.2)” the following policy is enforced: [assignment : Limited capability and availability policy]. Assignment Limited capability and availability policy : Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 59/85 Page 59/85 Deploying Test Features after TOE Delivery does not allow: (1) User Data to be manipulated, (2) sensitive User Data (EF.DG3 and EF.DG4) to be disclosed, (3) TSF data to be disclosed or manipulated (4) software to be reconstructed and (5) substantial information about construction of TSF to be gathered which may enable other attacks. The TOE shall meet the requirement “Limited availability (FMT_LIM.2)” as specified below (Common Criteria Part 2 extended). FMT_LIM.2 Limited availability FMT_LIM.2.1 The TSF shall be designed in a manner that limits their availability so that in conjunction with “Limited capability (FMT_LIM.1)” the following policy is enforced: [assignment : Limited capability and availability policy]. Assignment Limited capability and availability policy : Deploying Test Features after TOE Delivery does not allow, (1) User Data to be manipulated, (2) sensitive User Data (EF.DG3 and EF.DG4) to be disclosed, (3) TSF data to be disclosed or manipulated (4) software to be reconstructed and (5) substantial information about construction of TSF to be gathered which may enable other attacks. Application note 33: The formulation of “Deploying Test Features …” in FMT_LIM.2.1 might be a little bit misleading since the addressed features are no longer available (e.g. by disabling or removing the respective functionality). Nevertheless the combination of FMT_LIM.1 and FMT_LIM.2 is introduced provide an optional approach to enforce the same policy. Note that the term “software” in item 4 of FMT_LIM.1.1 and FMT_LIM.2.1 refers to both IC Dedicated and IC Embedded Software. 6.2.5.4 MANAGEMENT OF TSF DATA (FMT_MTD) Application note 34: The following SFR are iterations of the component Management of TSF data (FMT_MTD.1). The TSF data include but are not limited to those identified below. Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 60/85 Page 60/85 The TOE shall meet the requirement “Management of TSF data (FMT_MTD.1)” as specified below (Common Criteria Part 2). The iterations address different management functions and different TSF data. FMT_MTD.1/INI_ENA Management of TSF data – Writing of Initialization Data and Pre-personalization data FMT_MTD.1.1 / INI_ENA The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Assignment : write Assignment List of TSF data : Initialization Data and Pre-Personalization Data The authorized identified roles : the Manufacturer Application note 35: The pre-personalization Data includes but is not limited to the authentication reference data for the Personalization Agent which is the symmetric cryptographic Personalization Agent Authentication Key. FMT_MTD.1/INI_DIS Management of TSF data – Disabling of Read Access to Initialization Data and Pre-personalization data FMT_MTD.1.1 / INI_DIS The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Assignment : disable read access for users to Assignment List of TSF data : Initialization Data The authorized identified roles : the Personalization Agent Application note 36: According to P.Manufact the IC Manufacturer and the MRTD Manufacturer are the default users assumed by the TOE in the role Manufacturer during the Phase 2 “Manufacturing” but the TOE is not requested to distinguish between these users within the role Manufacturer. The TOE may restrict the ability to write the Initialization Data and the Pre-personalization Data by − − − − allowing to write these data only once and − − − − blocking the role Manufacturer at the end of the Phase 2. The IC Manufacturer may write the Initialization Data which includes but are not limited to the IC Identifier as required by FAU_SAS.1. The Initialization Data provides a unique identification of the IC which is used to trace the IC in the Phase 2 and 3 “personalization” but is not needed and may be Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 61/85 Page 61/85 misused in the Phase 4 “Operational Use”. Therefore the external read access shall be blocked. The MRTD Manufacturer will write the Pre-personalization Data. FMT_MTD.1/CVCA_INI Management of TSF data – Initialization of CVCA Certificate and Current Date FMT_MTD.1.1 / CVCA_INI The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Assignment : write Assignment List of TSF data : (1) initial Country Verifying Certification Authority Public Key, (2) initial Country Verifying Certification Authority Certificate, (3) initial Current Date. The authorized identified roles : Personalization Agent Application note 37: The initial Country Verifying Certification Authority Public Key may be written by the Manufacturer in the production or prepersonalization phase or by the Personalization Agent (cf. [R10], sec. 2.2.6). The initial Country Verifying Certification Authority Public Keys (and their updates later on) are used to verify the Country Verifying Certification Authority Link-Certificates. The initial Country Verifier Certification Authority Certificate and the initial Current Date is needed for verification of the certificates and the calculation of the Terminal Authorization. FMT_MTD.1/CVCA_UPD Management of TSF data – Country Verifying Certification Authority FMT_MTD.1.1 / CVCA_UPD The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Assignment : update Assignment List of TSF data : (1) Country Verifying Certification Authority Public Key, (2) Country Verifying Certification Authority Certificate, The authorized identified roles : Country Verifying Certification Authority Application note 38: The Country Verifier Certification Authority updates its asymmetric key pair and distributes the public key be means of the Country Verifier CA Link-Certificates (cf. [R10], sec. 2.2). The TOE updates its internal trust-point if a valid Country Verifier CA Link-Certificates (cf. FMT_MTD.3) is provided by the terminal (cf. [R10], sec. 2.2.3 and 2.2.4). Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 62/85 Page 62/85 FMT_MTD.1/DATE Management of TSF data – Current date FMT_MTD.1.1 / DATE The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Modify Assignment List of TSF data : Current date The authorized identified roles : (1) Country Verifying Certification Authority, (2) Document Verifier, (3) Domestic Extended Inspection System. Application note 39: The authorized roles are identified in their certificate (cf. [R10], sec. 2.2.4 and Table A.5) and authorized by validation of the certificate chain (cf. FMT_MTD.3). The authorized role of the terminal is part of the Certificate Holder Authorization in the card verifiable certificate provided by the terminal for the identification and the Terminal Authentication (cf. to [R10], annex A.3.3, for details). FMT_MTD.1/KEY_WRITE Management of TSF data – Key Write FMT_MTD.1.1 / KEY_WRITE The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Assignment : write Assignment List of TSF data : Document Basic Access Keys The authorized identified roles : the Personalization Agent Application note 40: The Country Verifying Certification Authority Public Key is the TSF data for verification of the certificates of the Document Verifier and the Extended Inspection Systems including the access rights for the Extended Access Control. FMT_MTD.1/CAPK Management of TSF data – Chip Authentication Private Key FMT_MTD.1.1 / CAPK The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations: [selection: create, load]]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Assignment : load Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 63/85 Page 63/85 Assignment List of TSF data : Chip authentication Private Key The authorized identified roles : Personalization Agent Application note 41: The component FMT_MTD.1/CAPK is refined by − − − − selecting the “load” operation. The verb “load” means here that the Chip Authentication Private Key is generated securely outside the TOE and written into the TOE memory. FMT_MTD.1/AAPK Management of TSF data – Chip Authentication Private Key FMT_MTD.1.1 / CAPK The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations: [selection: create, load]]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Assignment : load Assignment List of TSF data : Active authentication Private Key The authorized identified roles : Personalization Agent Application note 42: The component FMT_MTD.1/AAPK is refined by defining a selection between “create” and “load” for the assignment “other operations”. “Load” means here that the Active Authentication Private Key is generated securely outside the TOE and written into the TOE memory. “Create” means here that the Active Authentication Private Key is generated by the TOE itself. FMT_MTD.1/KEY_READ Management of TSF data – Key Read FMT_MTD.1.1 / KEY_READ The TSF shall restrict the ability to [selection: change_default, query, modify, delete, clear, [assignment: other operations]] the [assignment: list of TSF data] to [assignment: the authorized identified roles]. Selection Assignment : read Assignment List of TSF data : (1) Document Basic Access Keys, (2) Chip Authentication Private Key, (3) Personalization Agent Keys, (4) Active Authentication Private Key The authorized identified roles : none Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 64/85 Page 64/85 The TOE shall meet the requirement “Secure TSF data (FMT_MTD.3)” as specified below (Common Criteria Part 2). FMT_MTD.3 Secure TSF data FMT_MTD.3.1 The TSF shall ensure that only secure values of the certification chain are accepted for TSF data of the Terminal Authentication Protocol and the Access Control. Refinement Refinement: The certificate chain is valid if and only if: (1) the digital signature of the Inspection System Certificate can be verified as correct with the public key of the Document Verifier Certificate and the expiration date of the Inspection System Certificate is not before the Current Date of the TOE, (2) the digital signature of the Document Verifier Certificate can be verified as correct with the public key in the Certificate of the Country Verifying Certification Authority and the expiration date of the Document Verifier Certificate is not before the Current Date of the TOE, (3) the digital signature of the Certificate of the Country Verifying Certification Authority can be verified as correct with the public key of the Country Verifying Certification Authority known to the TOE and the expiration date of the Certificate of the Country Verifying Certification Authority is not before the Current Date of the TOE. The Inspection System Public Key contained in the Inspection System Certificate in a valid certificate chain is a secure value for the authentication reference data of the Extended Inspection System. The intersection of the Certificate Holder Authorizations contained in the certificates of a valid certificate chain is a secure value for Terminal Authorization of a successful authenticated Extended Inspection System. Application note 43: The Terminal Authentication is used for Extended Inspection System as required by FIA_UAU.4 and FIA_UAU.5. The Terminal Authorization is used as TSF data for access control required by FDP_ACF.1. 6.2.6 Class FPT Protection of the Security Functions The TOE shall prevent inherent and forced illicit information leakage for User Data and TSF Data. The security functional requirement FPT_EMSEC.1 addresses the inherent leakage. With respect to the forced leakage they have to be considered in combination with the security functional requirements “Failure with preservation of secure state (FPT_FLS.1)” and “TSF testing (FPT_TST.1)” on the one Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 65/85 Page 65/85 hand and “Resistance to physical attack (FPT_PHP.3)” on the other. The SFRs “Limited capabilities (FMT_LIM.1)”, “Limited availability (FMT_LIM.2)” and “Resistance to physical attack (FPT_PHP.3)” together with the SAR “Security architecture description” (ADV_ARC.1) prevent bypassing, deactivation and manipulation of the security features or misuse of TOE functions. 6.2.6.1 TOE EMANATION (FPT_EMSEC) The TOE shall meet the requirement “TOE Emanation (FPT_EMSEC.1)” as specified below (Common Criteria Part 2 extended). FPT_EMSEC.1 TOE Emanation FPT_EMSEC.1.1 The TOE shall not emit [assignment: types of emissions] in excess of [assignment: specified limits] enabling access to [assignment: list of types of TSF data] and [assignment: list of types of user data]. Assignment Types of emissions : side channel Specified limits : limits of the state of the art List of types of TSF data : Personalization Agent Authentication Keys and Chip Authentication Private Key and Active Authentication Private Key List of types of user data : none FPT_EMSEC.1.2 The TSF shall ensure [assignment: types of users] are unable to use the following interface [assignment: types of connection] to gain access to [assignment: list of types of TSF data] and [assignment: list of types of user data]. Assignment Types of users : any users Types of connection : smart card circuit contacts List of types of TSF data : Personalization Agent Authentication Keys and Chip Authentication Private Key and Active Authentication Private Key List of types of user data : none Application note 44: The TOE shall prevent attacks against the listed secret data where the attack is based on external observable physical phenomena of the TOE. Such attacks may be observable at the interfaces of the TOE or may be originated from internal operation of the TOE or may be caused by an attacker that varies the physical environment under which the TOE operates. The set of measurable physical phenomena is influenced by the technology employed to implement the smart card. The MRTD’s chip may provide a smart card contactless interface but may have also (not used by the Machine Readable Travel Document – Extended Access Control – CC IDeal Citiz Ref. : SSE-0000078620 Page 66/85 Page 66/85 terminal but maybe by an attacker) sensitive contacts according to ISO/IEC 7816-2 as well. Examples of measurable phenomena include, but are not limited to variations in the power consumption, the timing of signals and the electromagnetic radiation due to internal operations or data transmissions. 6.2.6.2 FAIL SECURE (FPT_FLS) The following security functional requirements address the protection against forced illicit information leakage including physical manipulation. The TOE shall meet the requirement “Failure with preservation of secure state (FPT_FLS.1)” as specified below (Common Criteria Part 2). FPT_FLS.1 Failure with preservation of secure state FPT_FLS.1.1 The TSF shall preserve a secure state when the following types of failures occur : [assignment: list of types of failures in the TSF]. Assignment List of types of failures in the TSF : (1) Exposure to out-of-range operating conditions where therefore a malfunction could occur, (2) Failure detected by TSF according to FPT_TST.1 6.2.6.3 TSF PHYSICAL PROTECTION (FPT_PHP) The TOE shall meet the requirement “Resistance to physical attack (FPT_PHP.3)” as specified below (Common Criteria Part 2). FPT_PHP.3 Resistance to physical attack FPT_PHP.3.1 The TSF shall resist [assignment: physical tampering scenarios] to the [assignment: list of TSF devices/elements] by responding automatically such that the SFRs are always enforced. Assignment Physical tampering scenarios : physical manipulation and physical probing List of TSF devices/elements : TSF Application note 45: The TOE will implement appropriate measures to continuously counter physical manipulation and physical probing. Due to the nature of these attacks (especially manipulation) the TOE can by no means detect attacks on all of its elements.
