SECURITY TARGET INTRODUCTION 1.1 ST Reference ST Title: AKiS-Pasaport v1.4N Security Target Lite, rev 6, 18.04.2011 This Security Target describes the TOE, intended IT environment (terminal, inspection system, and basic inspection system), security objectives, security requirements, security functions and all necessary rationale. 1.1.1 Operation Notation for Functional Requirements The CC allows several operations to be performed on functional requirements; refinement, selection, assignment, and iteration. Each of these operations is used in this ST. The refinement operation is used to add detail to a requirement, and thus further restricts a requirement. Refinement of security requirements is denoted by the word “refinement” in bold text and the added/changed words are in bold text. In cases where words from a CC requirement were deleted, a separate attachment indicates the words that were removed. The selection operation is used to select one or more options provided by the CC in stating a requirement. The assignment operation is used to assign a specific value to an unspecified parameter, such as the length of a password. The iteration operation is used when a component is repeated with varying operations. Iterated functional requirement components are shown with a “/IDENTIFIER” for the components which used more than once with varying operations. 1.2 TOE Reference TOE Identification: AKiS-Pasaport version 1.4N 1.3 TOE Overview 1.3.1 TOE definition AKiS-Pasaport v1.4N is a smart card which is designed to be used as Machine Readable Travel Document (MRTD). The Target of Evaluation (TOE) is the contactless integrated circuit chip of machine readable travel document (AKiS-Pasaport) programmed according to the Logical Data Structure (LDS) and providing the Basic Access Control according to ‘ICAO Doc 9303’. 1.3.2 TOE usage and security features for operational use The usage and security features are as defined in the MRTD with ICAO Application, Basic Access Control protection profile: A State or Organization issues MRTDs to be used by the holder for international travel. The traveler presents a MRTD to the inspection system to prove his or her identity. The MRTD in context of this ST contains (i) visual (eye readable) biographical data and portrait of the holder, UNCLASSIFIED AKIS PROJE GRUBU Rev. No: 06 Rev.

It presents visual readable data including (but not limited to) personal data of the MRTD holder (1) the biographical data on the biographical data page of the passport book, (2) the printed data in the Machine-Readable Zone (MRZ) and (3) the printed portrait. (b) the logical MRTD as data of the MRTD holder stored according to the Logical Data Structure as specified by ICAO on the contactless integrated circuit. It presents contactless readable data including (but not limited to) personal data of the MRTD holder (1) the digital Machine Readable Zone Data (digital MRZ data, EF.DG1), (2) the digitized portraits (EF.DG2), (3) the other data according to LDS (EF.DG5 to EF.DG16) and (4) the Document security object. The issuing State or Organization implements security features of the MRTD to maintain the authenticity and integrity of the MRTD and their data. The MRTD as the passport book and the MRTD’s chip is uniquely identified by the Document Number. The physical MRTD is protected by physical security measures (e.g. watermark on paper, security printing), logical (e.g. authentication keys of the MRTD’s chip) and organizational security measures (e.g. control of materials, personalization procedures). These security measures include the binding of the MRTD’s chip to the passport book. 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 ICAO defines the baseline security methods Passive Authentication and the optional advanced security methods Basic Access Control to the logical MRTD, Active Authentication of the MRTD’s chip, Extended Access Control to and the Data Encryption of additional sensitive biometrics as optional security measure in the ‘ICAO Doc 9303’. The Passive Authentication Mechanism and the Data Encryption are performed completely and independently on the TOE by the TOE environment. This ST addresses the protection of the logical MRTD (i) in integrity by writeonly-once access control and by physical means, and (ii) in confidentiality by the Basic Access Control Mechanism. (iii) in non-clonability by the Active Authentication Mechanism. The Basic Access Control is a security feature which is mandatory supported by the TOE. The inspection system (i) reads optically the MRTD, (ii) authenticates itself as inspection system by means of Document Basic Access Keys. After successful authentication of the inspection system the MRTD’s chip provides read access to the logical MRTD by means of private communication (secure messaging) with this inspection system.

TOE life cycle The TOE life cycle is described in terms of the four life cycle phases, but TOE actually comprises of phase 1 and step 3 of phase 2. Phase 1 “Development” (Step1) The TOE is developed in phase 1. The IC developer develops the integrated circuit, the IC Dedicated Software and the guidance documentation associated with these TOE components. (Step2) The software developer uses the guidance documentation for the integrated circuit and the guidance documentation for relevant parts of the IC Dedicated Software and develops the IC Embedded Software (operating system), the MRTD application and the guidance documentation associated with these TOE components. The manufacturing documentation of the IC including the IC Dedicated Software and the Embedded Software in the non-volatile non-programmable memories (ROM) is securely delivered to the IC manufacturer. The IC Embedded Software in the non-volatile programmable memories, the MRTD application and the guidance documentation is securely delivered to the MRTD manufacturer. Phase 2 “Manufacturing” (Step3) In a first step the TOE integrated circuit is produced containing the MRTD’s chip Dedicated Software and the parts of the MRTD’s chip Embedded Software in the non-volatile non-programmable memories (ROM). The IC manufacturer writes the IC Identification Data onto the chip to control the IC as MRTD material during the IC manufacturing and the delivery process to the MRTD manufacturer. The IC is securely delivered from the IC manufacturer to the MRTD manufacturer. (Step4) The MRTD manufacturer combines the IC with hardware for the contactless interface in the passport book. (Step5) The MRTD manufacturer initializes the MRTD by these steps (i) configuring the MRTD (choosing hash algorithm SHA-1 or SHA-256 for internal authenticate, enable attack counter, setting max BAC error number and delay, setting ATS historical bytes ) (ii) creating the MRTD application and (iii)equiping MRTD’s chips with pre-personalization Data. Creation of the application implies the creation of MF and ICAO.DF The pre-personalized MRTD together with the IC Identifier is securely delivered from the MRTD manufacturer to the Personalization Agent. The MRTD manufacturer also provides the relevant parts of the guidance documentation to the Personalization Agent. Phase 3 “Personalization of the MRTD” (Step6) The personalization of the MRTD includes (i) the survey of the MRTD holder’s biographical data, (ii) the enrolment of the MRTD holder biometric reference data (i.e. the digitized portraits and the optional biometric reference data), (iii) the printing of the visual readable data onto the physical MRTD, (iv) the writing of the TOE User Data and TSF Data into the logical MRTD and (v) configuration of the TSF.

Logical MRTD Data The logical MRTD data consists of the EF.COM, EF.DG1 to EF.DG16 (with different security needs) and the Document Security Object EF.SOD according to LDS. These data are user data of the TOE. The EF.COM lists the existing elementary files (EF) with the user data. The EF.DG1 to EF.DG13 and EF.DG 16 contain personal data of the MRTD holder. The Chip Authentication Public Key (EF.DG 14) is used by the inspection system for the Chip Authentication. The EF.SOD is used by the inspection system for Passive Authentication of the logical MRTD. The TOE specifies the BAC mechanisms with resistance against enhanced basic attack potential granting access to • Logical MRTD standard User Data (i.e. Personal Data) of the MRTD holder (EF.DG1, EF.DG2, EF.DG5 to EF.DG13, EF.DG16), • Chip Authentication Public Key in EF.DG14, • Active Authentication Public Key in EF.DG15, • Document Security Object (SOD) in EF.SOD, • Common data in EF.COM and Active Authentication mechanism. The TOE prevents read access to sensitive User Data • Sensitive biometric reference data (EF.DG3, EF.DG4). A sensitive asset is the following more general one. Authenticity of the MRTD’s chip The authenticity of the MRTD’s chip personalized by the issuing State or Organization for the MRTD holder is used by the traveler to prove his possession of a genuine MRTD. Subjects This ST considers the following subjects: Manufacturer The generic term for the IC Manufacturer producing the integrated circuit and the MRTD Manufacturer completing the IC to the MRTD’s chip. The Manufacturer is the default user of the TOE during the Phase 2 Manufacturing. The TOE does not distinguish between the users IC Manufacturer and MRTD Manufacturer using this role Manufacturer. Personalization Agent The agent is acting on behalf of the issuing State or Organization to personalize the MRTD for the holder by some or all of the following activities (i) establishing the identity the holder for the biographic data in the MRTD, (ii) enrolling the biometric reference data of the MRTD holder i.e. the portrait, the encoded finger image(s) and/or the encoded iris image(s) UNCLASSIFIED AKIS PROJE GRUBU Rev.

(iii) writing these data on the physical and logical MRTD for the holder as defined for global, international and national interoperability, (iv) writing the initial TSF data and (v) signing the Document Security Object. Terminal A terminal is any technical system communicating with the TOE through the contactless interface. Inspection system (IS) A technical system used by the border control officer of the receiving State (i) examining an MRTD presented by the traveler and verifying its authenticity and (ii) verifying the traveler as MRTD holder. The Basic Inspection System (BIS) (i) contains a terminal for the contactless communication with the MRTD’s chip, (ii) implements the terminals part of the Basic Access Control Mechanism and (iii) gets the authorization to read the logical MRTD under the Basic Access Control by optical reading the MRTD or other parts of the passport book providing this information. MRTD Holder The rightful holder of the MRTD for whom the issuing State or Organization personalized the MRTD. Traveler Person presenting the MRTD to the inspection system and claiming the identity of the MRTD holder. Attacker A threat agent trying (i) to identify and to trace the movement of the MRTD’s chip remotely (i.e. without knowing or optically reading the printed MRZ data), (ii) to read or to manipulate the logical MRTD without authorization, or (iii) to forge a genuine MRTD. 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. 3.2 Assumptions The assumptions describe the security aspects of the environment in which the TOE will be used or is intended to be used. A.MRTD_Manufact MRTD manufacturing on steps 4 to 6 It is assumed that appropriate functionality testing of the MRTD is used. It is assumed that security procedures are used during all manufacturing and test operations to maintain confidentiality and integrity of the MRTD and of its manufacturing and test data (to prevent any possible copy, modification, retention, theft or unauthorized use).

A.MRTD_Delivery MRTD delivery during steps 4 to 6 Procedures shall guarantee the control of the TOE delivery and storage process and conformance to its objectives: - Procedures shall ensure protection of TOE material/information under delivery and storage. - Procedures shall ensure that corrective actions are taken in case of improper operation in the delivery process and storage. - Procedures shall ensure that people dealing with the procedure for delivery have got the required skill. A.Pers_Agent Personalization of the MRTD’s chip The Personalization Agent ensures the correctness of (i) the logical MRTD with respect to the MRTD holder, (ii) the Document Basic Access Keys, (iii) the Chip Authentication Public Key (EF.DG14) if stored on the MRTD’s chip, and (iv) the Document Signer Public Key Certificate (if stored on the MRTD’s chip). The Personalization Agent signs the Document Security Object. The Personalization Agent bears the Personalization Agent Authentication to authenticate himself to the TOE by symmetric cryptographic mechanisms. A.Insp_Sys Inspection Systems for global interoperability The Inspection System is used by the border control officer of the receiving State (i) examining an MRTD presented by the traveler and verifying its authenticity and (ii) verifying the traveler as MRTD holder. The Basic Inspection System for global interoperability (i) includes the Country Signing Public Key and the Document Signer Public Key of each issuing State or Organization, and (ii) implements the terminal part of the Basic Access Control. The Basic Inspection System reads the logical MRTD under Basic Access Control and performs the Passive Authentication to verify the logical MRTD. A.BAC-Keys Cryptographic quality of Basic Access Control Keys The Document Basic Access Control Keys being generated and imported by the issuing State or Organization have to provide sufficient cryptographic strength. As a consequence of the ‘ICAO Doc 9303’ , the Document Basic Access Control Keys are derived from a defined subset of the individual printed MRZ data. It has to be ensured that these data provide sufficient entropy to withstand any attack based on the decision that the inspection system has to derive Document Access Keys from the printed MRZ data with enhanced basic attack potential. 3.3 Threats This section describes the threats to be averted by the TOE independently or in collaboration with its IT environment. These threats result from the TOE method of use in the operational environment and the assets stored in or protected by the TOE. The TOE in collaboration with its IT environment shall avert the threats as specified below. T.Chip_ID Identification of MRTD’s chip Adverse action: An attacker trying to trace the movement of the MRTD by identifying remotely the MRTD’s chip by establishing or listening to communications through the contactless communication interface.

Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance Asset: Anonymity of user, T.Skimming Skimming the logical MRTD Adverse action: An attacker imitates an inspection system trying to establish a communication to read the logical MRTD or parts of it via the contactless communication channel of the TOE. Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance Asset: confidentiality of logical MRTD data T.Eavesdropping Eavesdropping to the communication between TOE and inspection system Adverse action: An attacker is listening to an existing communication between the MRTD’s chip and an inspection system to gain the logical MRTD or parts of it. The inspection system uses the MRZ data printed on the MRTD data page but the attacker does not know these data in advance. Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance Asset: confidentiality of logical MRTD data T.Forgery Forgery of data on MRTD’s chip Adverse action: An attacker alters fraudulently the complete stored logical MRTD or any part of it including its security related data in order to deceive on an inspection system by means of the changed MRTD holder’s identity or biometric reference data. This threat comprises several attack scenarios of MRTD forgery. The attacker may alter the biographical data on the biographical data page of the passport book, in the printed MRZ and in the digital MRZ to claim another identity of the traveler. The attacker may alter the printed portrait and the digitized portrait to overcome the visual inspection of the inspection officer and the automated biometric authentication mechanism by face recognition. The attacker may alter the biometric reference data to defeat automated biometric authentication mechanism of the inspection system. The attacker may combine data groups of different logical MRTDs to create a new forged MRTD, e.g. the attacker writes the digitized portrait and optional biometric reference finger data read from the logical MRTD of a traveler into another MRTD’s chip leaving their digital MRZ unchanged to claim the identity of the holder this MRTD. The attacker may also copy the complete unchanged logical MRTD to another contactless chip. Threat agent: having enhanced basic attack potential, being in possession of one or more legitimate MRTDs Asset: authenticity of logical MRTD data The TOE shall avert the threats as specified below. T.Abuse-Func Abuse of Functionality Adverse action: An attacker may use functions of the TOE which shall not be used in the phase “Operational Use” in order (i) to manipulate User Data, (ii) to manipulate (explore, bypass, deactivate or change) security features or functions of the TOE or (iii) to disclose or to manipulate TSF Data. This threat addresses the misuse of the functions for the initialization and the personalization in the operational state after delivery to MRTD holder. UNCLASSIFIED AKIS PROJE GRUBU Rev. No: 06 Rev.

Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF. T.Information_Leakage Information Leakage from MRTD’s chip Adverse action: An attacker may exploit information which is leaked from the TOE during its usage in order to disclose confidential TSF data. The information leakage may be inherent in the normal operation or caused by the attacker. Leakage may occur through emanations, variations in power consumption, I/O characteristics, clock frequency, or by changes in processing time requirements. This leakage may be interpreted as a covert channel transmission but is more closely related to measurement of operating parameters, which may be derived either from measurements of the contactless interface (emanation) or direct measurements (by contact to the chip still available even for a contactless chip) and can then be related to the specific operation being performed. Examples are the Differential Electromagnetic Analysis (DEMA) and the Differential Power Analysis (DPA). Moreover the attacker may try actively to enforce information leakage by fault injection (e.g. Differential Fault Analysis). Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD Asset: confidentiality of logical MRTD and TSF data T.Phys-Tamper Physical Tampering Adverse action: An attacker may perform physical probing of the MRTD’s chip in order (i) to disclose TSF Data or (ii) to disclose/reconstruct the MRTD’s chip Embedded Software. An attacker may physically modify the MRTD’s chip in order to (i) modify security features or functions of the MRTD’s chip, (ii) modify security functions of the MRTD’s chip Embedded Software, (iii) modify User Data or (iv) to modify TSF data. The physical tampering may be focused directly on the disclosure or manipulation of TOE User Data (e.g. the biometric reference data for the inspection system) or TSF Data (e.g. authentication key of the MRTD’s chip) or indirectly by preparation of the TOE to following attack methods by modification of security features (e.g. to enable information leakage through power analysis). Physical tampering requires direct interaction with the MRTD’s chip internals. Techniques commonly employed in IC failure analysis and IC reverse engineering efforts may be used. Before that, the hardware security mechanisms and layout characteristics need to be identified. Determination of software design including treatment of User Data and TSF Data may also be a pre-requisite. The modification may result in the deactivation of a security function. Changes of circuitry or data can be permanent or temporary. Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF T.Malfunction Malfunction due to Environmental Stress Adverse action: An attacker may cause a malfunction of TSF or of the MRTD’s chip Embedded Software by applying environmental stress in order to (i) deactivate or modify security features or functions of the TOE or UNCLASSIFIED AKIS PROJE GRUBU Rev.

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 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. OT.Data_Int Integrity of personal data The TOE must ensure the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. The TOE must ensure that the inspection system is able to detect any modification of the transmitted logical MRTD data. OT.Data_Conf Confidentiality of personal data The TOE must ensure the confidentiality of the logical MRTD data groups EF.DG1 to EF.DG16. Read access to EF.DG1 to EF.DG16 is granted to terminals successfully authenticated as Personalization Agent. Read access to EF.DG1, EF.DG2 and EF.DG5 to EF.DG16 is granted to terminals successfully authenticated as Basic Inspection System. The Basic Inspection System shall authenticate itself by means of the Basic Access Control based on knowledge of the Document Basic Access Key. The TOE must ensure the confidentiality of the logical MRTD data during their transmission to the Basic Inspection System. The traveler grants the authorization for reading the personal data in EF.DG1, EF.DG2 and EF.DG5 to EF.DG16 to the inspection system by presenting the MRTD. The MRTD’s chip shall provide read access to these data for terminals successfully authenticated by means of the Basic Access Control based on knowledge of the Document Basic Access Keys. The security objective OT.Data_Conf requires the TOE to ensure the strength of the security function Basic Access Control Authentication. The Document Basic Access Keys are derived from the MRZ data defined by the TOE environment and are loaded into the TOE by the Personalization Agent. Therefore the sufficient quality of these keys has to result from the MRZ data’s entropy. Any attack based on decision of the ‘ICAO Doc 9303’ that the inspection system derives Document Basic Access is ensured by OE.BAC-Keys. Note that the authorization for reading the biometric data in EF.DG3 and EF.DG4 is only granted after successful Enhanced Access Control not covered by this protection profile. Thus the read access must be prevented even in case of a successful BAC Authentication. OT.Identification Identification and Authentication of the TOE The TOE must provide means to store IC Identification and Pre-Personalization Data in its nonvolatile memory. The IC Identification Data must provide a unique identification of the IC UNCLASSIFIED AKIS PROJE GRUBU Rev. No: 06 Rev.

The storage of the Pre- Personalization data includes writing of the Personalization Agent Key(s). In Phase 4 “Operational Use” the TOE shall identify itself only to a successful authenticated Basic Inspection System or Personalization Agent. The TOE security objective OT.Identification addresses security features of the TOE to support the life cycle security in the manufacturing and personalization phases. The IC Identification Data are used for TOE identification in Phase 2 “Manufacturing” and for traceability and/or to secure shipment of the TOE from Phase 2 “Manufacturing” into the Phase 3 “Personalization of the MRTD”. The OT.Identification addresses security features of the TOE to be used by the TOE manufacturing. In the Phase 4 “Operational Use” the TOE is identified by the Document Number as part of the printed and digital MRZ. The OT.Identification forbids the output of any other IC (e.g. integrated circuit card serial number ICCSN) or MRTD identifier through the contactless interface before successful authentication as Basic Inspection System or as Personalization Agent. The following TOE security objectives address the protection provided by the MRTD’s chip independent of the TOE environment. OT.Prot_Abuse-Func Protection against Abuse of Functionality After delivery of the TOE to the MRTD Holder, the TOE must prevent the abuse of test and support functions that may be maliciously used to (i) disclose critical User Data, (ii) manipulate critical User Data of the IC Embedded Software, (iii) manipulate Soft-coded ICEmbedded Software or (iv) bypass, deactivate, change or explore security features or functions of the TOE. Details of the relevant attack scenarios depend, for instance, on the capabilities of the Test Features provided by the IC Dedicated Test Software which are not specified here. OT.Prot_Inf_Leak Protection against Information Leakage The TOE must provide protection against disclosure of confidential TSF data stored and/or processed in the MRTD’s chip • 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. This objective pertains to measurements with subsequent complex signal processing due to normal operation of the TOE or operations enforced by an attacker. Details correspond to an analysis of attack scenarios which is not given here. OT.Prot_Phys-Tamper Protection against Physical Tampering The TOE must provide protection of the confidentiality and integrity of the User Data, the TSF Data, and the MRTD’s chip Embedded Software. This includes protection against attacks with enhanced-basic attack potential by means of • 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) UNCLASSIFIED AKIS PROJE GRUBU Rev.

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. 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 Operational Environment Issuing State or Organization The issuing State or Organization will implement the following security objectives of the TOE environment. OE.MRTD_Manufact Protection of the MRTD Manufacturing Appropriate functionality testing of the TOE shall be used in step 4 to 6. During all manufacturing and test operations, security procedures shall be used through phases 4, 5 and 6 to maintain confidentiality and integrity of the TOE and its manufacturing and test data. OE.MRTD_ Delivery Protection of the MRTD delivery Procedures shall ensure protection of TOE material/information under delivery including the following objectives: • 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 corrective actions are taken in case of improper operation in the delivery process (including if applicable any non-conformance to the confidentiality convention) and highlight all non-conformance to this process. Procedures shall ensure that people (shipping department, carrier, reception department) dealing with the procedure for delivery have got the required skill, training and knowledge to meet the procedure requirements and be able to act fully in accordance with the above expectations.

(ii) the access control for the user data and TSF data as described by the security objective OT.AC_Pers “Access Control for Personalization of logical MRTD”. Note the manufacturer equips the TOE with the Personalization Agent Key(s) according to OT.Identification “Identification and Authentication of the TOE”. The security objective OT.AC_Pers limits the management of TSF data and management of TSF to the Personalization Agent. The OSP P.Personal_Data “Personal data protection policy” requires the TOE (i) to support the protection of the confidentiality of the logical MRTD by means of the Basic Access Control and (ii) enforce the access control for reading as decided by the issuing State or Organization. This policy is implemented by the security objectives OT.Data_Int “Integrity of personal data” describing the unconditional protection of the integrity of the stored data and during transmission. The security objective OT.Data_Conf “Confidentiality of personal data” describes the protection of the confidentiality. The threat T.Chip_ID “Identification of MRTD’s chip” addresses the trace of the MRTD movement by identifying remotely the MRTD’s chip through the contactless communication interface. This threat is countered as described by the security objective OT.Identification by Basic Access Control using sufficiently strong derived keys as required by the security objective for the environment OE.BAC-Keys. The threat T.Skimming “Skimming digital MRZ data or the digital portrait” and T.Eavesdropping “Eavesdropping to the communication between TOE and inspection system” address the reading of the logical MRTD trough the contactless interface or listening the communication between the MRTD’s chip and a terminal. This threat is countered by the security objective OT.Data_Conf “Confidentiality of personal data” through Basic Access Control using sufficiently strong derived keys as required by the security objective for the environment OE.BAC-Keys. The threat T.Forgery “Forgery of data on MRTD’s chip” addresses the fraudulent alteration of the complete stored logical MRTD or any part of it. The security objective OT.AC_Pers “Access Control for Personalization of logical MRTD“ requires the TOE to limit the write access for the logical MRTD to the trustworthy Personalization Agent (cf. OE.Personalization). The TOE will protect the integrity of the stored logical MRTD according the security objective OT.Data_Int “Integrity of personal data” and OT.Prot_Phys-Tamper “Protection against Physical Tampering”. The examination of the presented MRTD passport book according to OE.Exam_MRTD “Examination of the MRTD passport book” shall ensure that passport book does not contain a sensitive contactless chip which may present the complete unchanged logical MRTD. The TOE environment will detect partly forged logical MRTD data by means of digital signature which will be created according to OE.Pass_Auth_Sign “Authentication of logical MRTD by Signature” and verified by the inspection system according to OE.Passive_Auth_Verif “Verification by Passive Authentication”. The threat T.Abuse-Func “Abuse of Functionality” addresses attacks using the MRTD’s chip as production material for the MRTD and misuse of the functions for personalization in the operational state after delivery to MRTD holder to disclose or to manipulate the logical MRTD.

The extended components defined in PP “Machine Readable Travel Document with „ICAO Application”, Basic Access Control” are used. These extended components are FAU_SAS, FCS_RND, FMT_LIM and FPT_EMSEC, and defined in the PP as given below. 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 behavior This family defines functional requirements for the storage of audit data. Component leveling FAU_SAS.1: Requires the TOE to provide the possibility to store audit data. Management: FAU_SAS.1 There are no management activities foreseen. Audit: FAU_SAS.1 There are no actions defined to be auditable. FAU_SAS.1 Audit storage Hierarchical to: No other components. Dependencies: No dependencies. FAU_SAS.1.1 The TSF shall provide [assignment: authorized users] with the capability to store [assignment: list of audit information] in the audit records. 5.2 Definition of the Family FCS_RND To define the IT security functional requirements of the TOE a sensitive family (FCS_RND) of the Class FCS (cryptographic support) is defined here. This family describes the functional requirements for random number generation used for cryptographic purposes. The component FCS_RND is not limited to generation of cryptographic keys unlike the component FCS_CKM.1. The similar component FIA_SOS.2 is intended for non-cryptographic use. The family “Generation of random numbers (FCS_RND)” is specified as follows. FCS_RND Generation of random numbers Family behavior FAU SAS Audit data storage 1 UNCLASSIFIED AKIS PROJE GRUBU Rev.

This family defines quality requirements for the generation of random numbers which are intended to be used 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 FMT_LIM The family FMT_LIM describes the functional requirements for the Test Features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE show that no other class is appropriate to address the specific issues of preventing the abuse of functions by limiting the capabilities of the functions and by limiting their availability. The family “Limited capabilities and availability (FMT_LIM)” is specified as follows. FMT_LIM Limited capabilities and availability Family behavior This family defines requirements that limit the capabilities and availability of functions in a combined manner. Note that FDP_ACF restricts the access to functions whereas the Limited capability of this family requires the functions themselves to be designed in a specific manner. Component leveling: FMT_LIM.1: Limited capabilities requires that the TSF is built to provide only the capabilities (perform action, gather information) necessary for its genuine purpose. FMT_LIM.2: Limited availability requires that the TSF restrict the use of functions (refer to Limited capabilities (FMT_LIM.1)). This can be achieved, for instance, by removing or by disabling functions in a specific phase of the TOE’s lifecycle. Management: FMT_LIM.1, FMT_LIM.2 There are no management activities foreseen.

To define the IT security functional requirements of the TOE a sensitive family (FMT_LIM) of the Class FMT (Security Management) is defined here. This family describes the functional requirements for the Test Features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE show that no other class is appropriate to address the specific issues of preventing the abuse of functions by limiting the capabilities of the functions and by limiting their availability. The TOE Functional Requirement “Limited capabilities (FMT_LIM.1)” is specified as follows. FMT_LIM.1 Limited capabilities Hierarchical to: No other components. Dependencies: FMT_LIM.2 Limited availability. FMT_LIM.1.1 The TSF shall be designed in a manner that limits their capabilities so that in conjunction with “Limited availability (FMT_LIM.2)” the following policy is enforced [assignment: Limited capability and availability policy]. 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 their availability so that in conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced [assignment: Limited capability and availability policy]. The functional requirements FMT_LIM.1 and FMT_LIM.2 assume that there are two types of mechanisms (limited capabilities and limited availability) which together shall provide protection in order to enforce the policy. This also allows that (i) the TSF is provided without restrictions in the product in its user environment but its capabilities are so limited that the policy is enforced or conversely (ii) the TSF is designed with test and support functionality that is removed from, or disabled in, the product prior to the Operational Use Phase. The combination of both requirements shall enforce the policy. 5.4 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 requirements of the TOE. The TOE shall prevent attacks against the TOE and other secret data where the attack is based on external observable physical phenomena of the TOE. Examples of such attacks are evaluation of TOE’s electromagnetic radiation, simple power analysis (SPA), differential power analysis (DPA), timing attacks, etc. This family describes the functional requirements for the limitation of intelligible emanations which are not directly addressed by any other component of CC part 2. The family “TOE Emanation (FPT_EMSEC)” is specified as follows. UNCLASSIFIED AKIS PROJE GRUBU Rev. No: 06 Rev.

FIA_UID.1 Timing of identification Hierarchical to: No other components. Dependencies: No dependencies. FIA_UID.1.1 The TSF shall allow 1. to read the Initialization Data in Phase 2 “Manufacturing”, 2. to read the random identifier in Phase 3 “Personalization of the MRTD”, 3. to read the random identifier in Phase 4 “Operational Use”22 on behalf of the user to be performed before the user is identified. FIA_UID.1.2 The TSF shall require each user to be successfully identified before allowing any other TSF-mediated actions on behalf of that user. The IC manufacturer and the MRTD manufacturer write the Initialization Data and/or Pre- personalization Data in the audit records of the IC during the Phase 2 “Manufacturing”. The audit records can be written only in the Phase 2 Manufacturing of the TOE. At this time the Manufacturer is the only user role available for the TOE. The MRTD manufacturer may create the user role Personalization Agent for transition from Phase 2 to Phase 3 “Personalization of the MRTD”. The users in role Personalization Agent identify themselves by means of selecting the authentication key. After personalization in the Phase 3 (i.e. writing the digital MRZ and the Document Basic Access Keys) the user role Basic Inspection System is created by writing the Document Basic Access Keys. The Basic Inspection System is identified as default user after power up or reset of the TOE i.e. the TOE will use the Document Basic Access Key to authenticate the user as Basic Inspection System. In the “Operational Use” phase the MRTD must not allow anybody to read the ICCSN, the MRTD identifier or any other unique identification before the user is authenticated as Basic Inspection System (cf. T.Chip_ID). Note that the terminal and the MRTD’s chip use a (randomly chosen) identifier for the communication channel to allow the terminal to communicate with more then one RFID. If this identifier is randomly selected it will not violate the OT.Identification. If this identifier is fixed the ST writer should consider the possibility to misuse this identifier to perform attacks addressed by T.Chip_ID. 22 [assignment: list of TSF-mediated actions] UNCLASSIFIED AKIS PROJE GRUBU Rev.

The TOE shall meet the requirement “Timing of authentication (FIA_UAU.1)” as specified below (Common Criteria Part 2). FIA_UAU.1 Timing of authentication Hierarchical to: No other components. Dependencies: FIA_UID.1 Timing of identification. FIA_UAU.1.1 The TSF shall allow 1. to read the Initialization Data in Phase 2 “Manufacturing”, 2. to read the random identifier in Phase 3 “Personalization of the MRTD”, 3. to read the random identifier in Phase 4 “Operational Use”23 on behalf of the user to be performed before the user is authenticated. FIA_UAU.1.2 The TSF shall require each user to be successfully authenticated before allowing any other TSF-mediated actions on behalf of that user. The Basic Inspection System and the Personalization Agent authenticate themselves. The TOE shall meet the requirements of “Single-use authentication mechanisms (FIA_UAU.4)” as specified below (Common Criteria Part 2). FIA_UAU.4 Single-use authentication mechanisms - Single-use authentication of the Terminal by the TOE Hierarchical to: No other components. Dependencies: No dependencies. FIA_UAU.4.1 The TSF shall prevent reuse of authentication data related to 1. Basic Access Control Authentication Mechanism, 2. Authentication Mechanism based on [Triple-DES]24 . FIA_UAU.4.1/AA The TSF shall prevent reuse of authentication data related to Active Authentication Mechanism, The authentication mechanisms may use either a challenge freshly and randomly generated by the TOE to prevent reuse of a response generated by a terminal in a successful authentication attempt. However, the authentication of Personalisation Agent may rely on other mechanisms ensuring protection against replay attacks, such as the use of an internal counter as a diversifier. The Basic Access Control Mechanism is a mutual device authentication mechanism defined in [6]. In the first step the terminal authenticates itself to the MRTD’s chip and the MRTD’s chip authenticates to the terminal in the second step. In this second step the MRTD’s chip provides the terminal with a challenge-response-pair which allows a unique identification of the MRTD’s chip with some probability depending on the entropy of the Document Basic Access Keys. Therefore the TOE shall stop further communications if the terminal is not successfully authenticated in the first step of the protocol to fulfill the security objective OT.Identification and to prevent T.Chip_ID. 23 [assignment: list of TSF-mediated actions] 24 [assignment: identified authentication mechanism(s)] UNCLASSIFIED AKIS PROJE GRUBU Rev.

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 misused in the Phase 4 “Operational Use”. Therefore the external read access shall be blocked. The MRTD Manufacturer will write the Pre-personalization 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 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.

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 Hierarchical to: No other components. Dependencies: No Dependencies. FPT_FLS.1.1 The TSF shall preserve a secure state when the following types of failures occur: 1. Exposure to out-of-range operating conditions where therefore a malfunction could occur, 2. failure detected by TSF according to FPT_TST.1 62 . The TOE shall meet the requirement “TSF testing (FPT_TST.1)” as specified below (Common Criteria Part 2). FPT_TST.1 TSF testing Hierarchical to: No other components. Dependencies: No Dependencies. FPT_TST.1.1 The TSF shall run a suite of self tests [at the conditions [during initial startup, when any command is received, during cryptographic operations]] to demonstrate the correct operation of the TSF63 . FPT_TST.1.2 The TSF shall provide authorised users with the capability to verify the integrity of TSF data64 . FPT_TST.1.3 The TSF shall provide authorised users with the capability to verify the integrity of stored TSF executable code. 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 Hierarchical to: No other components. Dependencies: No dependencies. FPT_PHP.3.1 The TSF shall resist physical manipulation and physical probing 65 to the TSF 66 by responding automatically such that the SFRs are always enforced. The TOE will implement appropriate measures to continuously counter physical manipulation and physical probing. Due to the nature of these attacks (especially manipulation) the TOE can by no means detect attacks on all of its elements. Therefore, permanent protection against these attacks is required ensuring that the TSP could not be violated at any time. Hence, “automatic response” means here (i) assuming that there might be an attack at any time and (ii) countermeasures are provided at any time. 62 [assignment: list of types of failures in the TSF] 63 [selection: [assignment: parts of TSF], the TSF] 64 [selection: [assignment: parts of TSF], TSF data] 65 [assignment: physical tampering scenarios] 66 [assignment: list of TSF devices/elements] UNCLASSIFIED AKIS PROJE GRUBU Rev.

The write access to the logical MRTD data are defined by the SFR FDP_ACC.1 and FDP_ACF.1 as follows: only the successfully authenticated Personalization Agent is allowed to write the data of the groups EF.DG1 to EF.DG16 of the logical MRTD only once. The authentication of the terminal as Personalization Agent shall be performed by TSF according to SRF FIA_UAU.4 and FIA_UAU.5. The Personalization Agent can be authenticated by using the symmetric authentication mechanism (FCS_COP.1/ AUTH). FIA_AFL.1/INI and FIA_AFL.1/PER describe the authentication failures and the actions taken after unsuccessfull authentication attempts during initialization and personalization. In case of using the BAC mechanism the SFR FIA_UAU.6 describes the re-authentication and FDP_UCT.1 and FDP_UIT.1 the protection of the transmitted data by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1, FCS_COP.1/SHA, FCS_RND.1 (for key generation), and FCS_COP.1/ENC as well as FCS_COP.1/MAC for the ENC_MAC_Mode. The SFR FMT_SMR.1 lists the roles (including Personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization) setting the Document Basic Access Keys according to the SFR FMT_MTD.1/KEY_WRITE as authentication reference data. The SFR FMT_MTD.1/KEY_READ prevents read access to the secret key of the Personalization Agent Keys and ensure together with the SFR FCS_CKM.4, FPT_EMSEC.1, FPT_FLS.1 and FPT_PHP.3 the confidentially of these keys. The security objective OT.Data_Int “Integrity of personal data” requires the TOE to protect the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. The write access to the logical MRTD data is defined by the SFR FDP_ACC.1 and FDP_ACF.1 in the same way: only the Personalization Agent is allowed to write the data of the groups EF.DG1 to EF.DG16 of the logical MRTD (FDP_ACF.1.2, rule 1) UNCLASSIFIED AKIS PROJE GRUBU Rev.

FDP_ACF.1.4). The SFR FMT_SMR.1 lists the roles (including Personalization Agent) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization). The authentication of the terminal as Personalization Agent shall be performed by TSF according to SRF FIA_UAU.4, FIA_UAU.5 and FIA_UAU.6 using either FCS_COP.1/ENC and FCS_COP.1/MAC or FCS_COP.1/AUTH. The security objective OT.Data_Int “Integrity of personal data” requires the TOE to ensure that the inspection system is able to detect any modification of the transmitted logical MRTD data by means of the BAC mechanism. The SFR FIA_UAU.6, FDP_UCT.1 and FDP_UIT.1 requires the protection of the transmitted data by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1, FCS_COP.1/SHA, FCS_RND.1 (for key generation), and FCS_COP.1/ENC and FCS_COP.1/MAC for the ENC_MAC_Mode. The SFR FMT_MTD.1/KEY_WRITE requires the Personalization Agent to establish the Document Basic Access Keys in a way that they cannot be read by anyone in accordance to FMT_MTD.1/KEY_READ. FCS_COP.1/SIGN requires the protection of the integrity of the logical MRTD data by active authentication mechanism. The security objective OT.Data_Conf “Confidentiality of personal data” requires the TOE to ensure the confidentiality of the logical MRTD data groups EF.DG1 to EF.DG16. The SFR FIA_UID.1 and FIA_UAU.1 allow only those actions before identification respective authentication which do not violate OT.Data_Conf. In case of failed authentication attempts FIA_AFL.1 enforces additional waiting time prolonging the necessary amount of time for facilitating a brute force attack. The read access to the logical MRTD data is defined by the FDP_ACC.1 and FDP_ACF.1.2: the successful authenticated Personalization Agent is allowed to read the data of the logical MRTD (EF.DG1 to EF.DG16). The successful authenticated Basic Inspection System is allowed to read the data of the logical MRTD (EF.DG1, EF.DG2 and EF.DG5 to EF.DG16). The SFR FMT_SMR.1 lists the roles (including Personalization Agent and Basic Inspection System) and the SFR FMT_SMF.1 lists the TSF management functions (including Personalization for the key management for the Document Basic Access Keys). FCS_COP.1/SIGN requires the protection of confidentiality of the logical MRTD data by active authentication mechanism. FIA_AFL.1/EXC, FIA_AFL.1/BAC, FIA_AFL.1/INI and FIA_AFL.1/PER prevent unauthenticated users to access logical MRTD data. The SFR FIA_UAU.4 prevents reuse of authentication data to strengthen the authentication of the user. The SFR FIA_UAU.5 enforces the TOE to accept the authentication attempt as Basic Inspection System only by means of the Basic Access Control Authentication Mechanism with the Document Basic Access Keys. Moreover, the SFR FIA_UAU.6 requests secure messaging after successful authentication of the terminal with Basic Access Control Authentication Mechanism which includes the protection of the transmitted data in ENC_MAC_Mode by means of the cryptographic functions according to FCS_COP.1/ENC and FCS_COP.1/MAC (cf. The SFR FDP_UCT.1 and FDP_UIT.1). (for key generation), and FCS_COP.1/ENC and FCS_COP.1/ MAC for the ENC_MAC_Mode. The SFR FCS_CKM.1, FCS_CKM.4, FCS_COP.1/SHA and FCS_RND.1 establish the key management for the secure messaging keys. The SFR FMT_MTD.1/KEY_WRITE addresses the key management and FMT_MTD.1/KEY_READ prevents reading of the Document Basic Access Keys. Note, neither the security objective OT.Data_Conf nor the SFR FIA_UAU.5 requires the Personalization Agent to use the Basic Access Control Authentication Mechanism or secure messaging.

The security objective OT.Identification “Identification and Authentication of the TOE” address the storage of the IC Identification Data uniquely identifying the MRTD’s chip in its non-volatile memory. This will be ensured by TSF according to SFR FAU_SAS.1. Furthermore, the TOE shall identify itself only to a successful authenticated Basic Inspection System in Phase 4 “Operational Use”. The SFR FMT_MTD.1/INI_ENA allows only the Manufacturer to write Initialization Data and Pre-personalization Data (including the Personalization Agent key). The SFR FMT_MTD.1/INI_DIS allows the Personalization Agent to disable Initialization Data if their usage in the phase 4 “Operational Use” violates the security objective OT.Identification. The SFR FIA_UID.1 and FIA_UAU.1 do not allow reading of any data uniquely identifying the MRTD’s chip before successful authentication of the Basic Inspection Terminal and will stop communication after unsuccessful authentication attempt. In case of failed authentication attempts related to BAC authentication protocol, FIA_AFL.1/BAC enforces additional waiting time prolonging the necessary amount of time for facilitating a brute force attack. The security objective OT.Prot_Abuse-Func “Protection against Abuse of Functionality” is ensured by the SFR FMT_LIM.1 and FMT_LIM.2 which prevent misuse of test functionality of the TOE or other features which may not be used after TOE Delivery. The security objective OT.Prot_Inf_Leak “Protection against Information Leakage” requires the TOE to protect confidential TSF data stored and/or processed in the MRTD’s chip against disclosure - by measurement and analysis of the shape and amplitude of signals or the time between events found by measuring signals on the electromagnetic field, power consumption, clock, or I/O lines, which is addressed by the SFR FPT_EMSEC.1, - by forcing a malfunction of the TOE, which is addressed by the SFR FPT_FLS.1 and FPT_TST.1, and/or - by a physical manipulation of the TOE, which is addressed by the SFR FPT_PHP.3. The security objective OT.Prot_Phys-Tamper “Protection against Physical Tampering” is covered by the SFR FPT_PHP.3. The security objective OT.Prot_Malfunction “Protection against Malfunctions” is covered by (i) the SFR FPT_TST.1 which requires self tests to demonstrate the correct operation and tests of authorized users to verify the integrity of TSF data and TSF code, and (ii) the SFR FPT_FLS.1 which requires a secure state in case of detected failure or operating conditions possibly causing a malfunction. 6.3.2 Dependency Rationale The dependency analysis for the security functional requirements shows that the basis for mutual support and internal consistency between all defined functional requirements is satisfied. All dependencies between the chosen functional components are analyzed, and non- dissolved dependencies are appropriately explained. The table 4 shows the dependencies between the SFR of the TOE.

Table 6 – Dependencies between the SFR for the TOE Justification for non-satisfied dependencies between the SFR for TOE: No. 1: The hash algorithm required by the SFR FCS_COP.1/SHA does not need any key material. Therefore neither a key generation (FCS_CKM.1) nor an import (FDP_ITC.1/2) is necessary. No. 2: The SFR FCS_COP.1/AUTH uses the symmetric Personalization Key permanently stored during the Pre-Personalization process (cf. FMT_MTD.1/INI_ENA) by the manufacturer. Thus there is neither the necessity to generate or import a key during the addressed TOE lifecycle by the means of FCS_CKM.1 or FDP_ITC. Since the key is permanently stored within the TOE there is no need for FCS_CKM.4, too. No. 3: The access control TSF according to FDP_ACF.1 uses security attributes which are defined during the personalization and are fixed over the whole life time of the TOE. No management of these security attribute (i.e. SFR FMT_MSA.1 and FMT_MSA.3) is necessary here.

There is no need for SFR FTP_ITC.1, e.g. to require this communication channel to be logically distinct from other communication channels since there is only one channel. Since the TOE does not provide a direct human interface a trusted path as required by FTP_TRP.1 is not applicable here. 6.3.3 Security Assurance Requirements Rationale The EAL4 was chosen to permit a developer to gain maximum assurance from positive security engineering based on good commercial development practices which, though rigorous, do not require substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at which it is likely to be economically feasible to retrofit to an existing product line. EAL4 is applicable in those circumstances where developers or users require a moderate to high level of independently assured security in conventional commodity TOEs and are prepared to incur sensitive security specific engineering costs. The selection of the component ALC_DVS.2 provides a higher assurance of the security of the MRTD’s development and manufacturing especially for the secure handling of the MRTD’s material. The component ALC_DVS.2 augmented to EAL4 has no dependencies to other security Requirements Dependencies ALC_DVS.2: no dependencies. 6.3.4 Security Requirements – Mutual Support and Internal Consistency The following part of the security requirements rationale shows that the set of security requirements for the TOE consisting of the security functional requirements (SFRs) and the security assurance requirements (SARs) together form a mutually supportive and internally consistent whole. The analysis of the TOE´s security requirements with regard to their mutual support and internal consistency demonstrates: The dependency analysis in Dependency Rationale for the security functional requirements shows that the basis for mutual support and internal consistency between all defined functional requirements is satisfied. All dependencies between the chosen functional components are analyzed, and non-satisfied dependencies are appropriately explained. The assurance class EAL4 is an established set of mutually supportive and internally consistent assurance requirements. The dependency analysis for the sensitive assurance components in section Security Assurance Requirements Rationale shows that the assurance requirements are mutually supportive and internally consistent as all (sensitive) dependencies are satisfied and no inconsistency appears. Inconsistency between functional and assurance requirements could only arise if there are functional-assurance dependencies which are not met, a possibility which has been shown not to arise in Dependency Rationale and Security Assurance Requirements Rationale. Furthermore, as also discussed in Security Assurance Requirements Rationale, the chosen assurance components are adequate for the functionality of the TOE.
