It is composed of both an Integrated Circuit (IC) and an embedded software providing secure data management following ePassport specifications (BAC, EAC) this document is therefore a composite Security Target (ST). In the following, the smartcard will be called “Target Of Evaluation” or TOE. The TOE is a versatile device that can be easily configured in order to operate in different modes including BAC ePassport and EAC ePassport,. It possesses a dual interface to perform contact and contactless communications to go beyond current ePassport usages. This device can be proposed as inlay to integrate in secure document booklet but can also be provided in a regular ID1 format. 7 FQR 110 6669 Ed1 2 TOE Description This part of the Security Target describes the TOE as an aid to the understanding of its security requirements. It addresses the product type, the intended usage and the main features of the TOE. 2.1 TOE usages State or organisation issues TOEs to be used by the holder to prove his/her identity and claiming associated rights. For instance, it can be used to check identity at customs in an ePassport configuration, verifying authenticity of electronic visa stored on the card and correspondence with the holder. In order to pass successfully the control, the holder presents its personal TOE to the inspection system to first prove his/her identity. The inspection system is under control of an authorised agent and can be either a desktop device such as those present in airports or a portable device to be used on the field. The TOE in context of this security target contains: • Visual (eye readable) biographical data and portrait of the holder printed in the booklet • A separate data summary (MRZ or keydoc data) for visual and machine reading using OCR methods in the Machine Readable Zone (MRZ or keydoc area) • And data elements stored on the TOE’s chip for contact-less machine reading. The authentication of the holder is based on: • The possession of a valid TOE personalized for a holder with the claimed identity as given on the biographical data page and • The Biometric matching performed on the Inspection system using the reference data stored in the TOE. When holder has been authenticated the issuing State or Organization can performed extra authentications in order to gain rights required to grant access to some sensitive information such as “visa information”… The issuing State or Organization ensures the authenticity of the data of genuine TOEs. The receiving State trusts a genuine TOE of an issuing State or Organization. The TOE can be viewed as the combination: • A physical TOE in form of paper or plastic with an embedded chip and possibly an antenna. It presents visual readable data including (but not limited to) personal data of the TOE holder (1) The biographical data on the biographical data page of the passport book, (2) The printed data in the Machine-Readable Zone (MRZ) or keydoc area that identifies the device and (3) The printed portrait. • A logical TOE as data of the TOE holder stored according to the Logical Data Structure as specified by ICAO and extended in [R6], [R7], [R8] on the contactless integrated circuit. It presents contact or contact-less readable data including (but not limited to) personal data of the TOE holder (4) The digital Machine Readable Zone Data (digital MRZ data or keydoc data, DG1), 8 FQR 110 6669 Ed1 (5) The digitized portraits, (6) The optional biometric reference data of finger(s) or iris image(s) or both (7) The other data according to LDS (up to DG24) and (8) The Document security object. The issuing State or Organization implements security features of the TOE to maintain the authenticity and integrity of the TOE and its data. The TOE as the physical device and the MRTD’s chip is uniquely identified by the document number. The physical TOE is protected by physical security measures (e.g. watermark on paper, security printing), logical (e.g. authentication keys of the TOE’s chip) and organisational security measures (e.g. control of materials, personalisation procedures). These security measures include the binding of the TOE’s chip to the physical support. The logical TOE 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 TOE’s chip. 2.2 TOE architecture The Target of Evaluation (TOE) is a smartcard composed of the following components: • An underlying P5CD081, P5CC081 or P5CD041 chip of NXP, • A native “BIOS FAT” allowing efficient access to chip functionalities, • A dedicated highly secure cryptographic library, • A personalisation application on top of the BIOS, • An LDS application providing both the BAC/EAC features on top of the BIOS. Figure 1 TOE architecture BIOS FAT full (Oberthur Technologies) P5Cx081 / P5CD041 (NXP) TOE Perso (OT) BAC LDS application (Oberthur Technologies) Non-evaluated features Cryptography library (Oberthur Technologies) 9 FQR 110 6669 Ed1 2.2.1 Integrated Circuit (IC) The TOE relies on the functional and security features of the P5CD081. This chip is designed to embed the secure code of Oberthur Technologies for the production of smart cards. This chip provides the following major features: • Die integrity, • Monitoring of environmental parameters, • Protection mechanisms against faults, • A FameXE Enhanced Pulbic key coprocessor especially for RSA and ECC, • A 3DES coprocessor, • An AES coprocessor, • AIS-31 class P2 compliant Random Number Generator, • A CRC calculation block. For more details, see [R14]. 2.2.2 Basic Input/Output System (BIOS) The native BIOS of Oberthur Technologies provides an efficient and easy way to access chip features from the applications. Indeed, it is based on services organized according to a multi-layer design which allows applications to use a high level interface completely independent of the chip. The main features of the OS are the following: • EEPROM management including secure data processing, • Other memories management, • Transaction management, • APDU protocol management, • Low level T=0 ; T=1 and T=CL management, • Error processing, • Advanced securities activation. 2.2.3 Cryptographic library A dedicated cryptographic library is is designed and embedded on the TOE to provide the highest security level and best tuned performances. It provides the following algorithms: Feature Embedded SHA-1, SHA-224, SHA 256, SHA-384 and SHA-512 bits RSA CRT from 1024, to2048 bits (by steps of 256 bits) RSA SFM from 1024 to 2048 bits (by steps of 256 bits) ECC with key sizes from 192 to 521bits 3DES with 112 bits key size AES with 128, 192, 256 key sizes 10 FQR 110 6669 Ed1 2.2.4 Resident application This application manages the TOE in pre-personalisation, personalisation and use phase in order to configure the card in the expected way. It implements and control access to the following services: • MSK management, • File management including data reading and writing, • Key generation, • Key injection, • PIN management, • Locks management. The resident application can be addressed: • in clear mode for secure environment or non-sensitive commands, • using a 3DES secure channel otherwise. 2.2.5 LDS application The Logical Data Structure (LDS) application is a generic filesystem that can be configured to match especially ICAO specifications for ePassports BAC and EAC. ISO specifications for IDL BAP and EAP are also matched, but not in the TOE scope. It also includes commands and protocol management specified in [R15] used to grant access to sensitive data stored in the filesystem. Here are the main features provided by the LDS application and present in the evaluation scope: Feature Embedded In the ST scope1 References BAC [R2], [R3] EAC [R2], [R3], [R4] Active Authentication (RSA CRT/SFM and ECC) [R2], [R3] Cryptosystem migration (Algorithm change during certificate verification transaction) [R2], [R3], [R4] BAP [R6], [R7], [R8] EAP [R6], [R7], [R8] 2.2.5.1 Basic Access Control (BAC) The Basic Access Control (BAC) is a security feature that is supported by the TOE. The inspection system • reads the printed data in the MRZ (for ePassport), 1 Features not included in the present Security Target are covered in the context of other CC certificates of the same product. 11 FQR 110 6669 Ed1 • authenticates itself as inspection system by means of keys derived from MRZ data. After successful 3DES based authentication, the TOE provides read access to data requiring BAC rights by means of a private communication (secure messaging) with the inspection system. 2.2.5.2 Basic Access Protection (BAP) The Basic Access Protection (BAP) is especially used in the context of IDL as an alternative to BAC. Indeed it is actually a generalisation of BAC allowing usage of extra algorithms and key length. It exists in 4 modes: • BAP1 - 3DES with key length of 128 bits (equivalent to BAC), • BAP2 - AES with key length of 128 bits, • BAP3 - AES with key length of 192 bits, • BAP4 - AES with key length of 256 bits. Following Secure messaging is performed using the algorithm used in the selected BAP mode. Note that the term MRZ is specific to ICAO standard; [R8] uses the term “Keydoc” which refers to an equivalent unique identifier printed on the physical TOE as a random number or barcode. This feature is not in the TOE scope. 2.2.5.3 Active Authentication (AA) The Active Authentication of the TOE is an optional feature that may be implemented. It ensures that the TOE has not been substituted, by means of a challenge-response protocol between the inspection system and the TOE. For this purpose the chip contains its own Active Authentication RSA or ECC Key pair. A hash representation of Data Group 15 (DG15, see 2.5.1) Public Key is stored in the Document Security Object (SOD, see 2.5.1) and therefore authenticated by the issuer’s digital signature. The corresponding Private Key is stored in the TOE’s secure memory. The TOE supports the loading and generation of the Active Authentication RSA or ECC Key pair. 2.2.5.4 Extended Access Control (EAC) The Extended Access Control (EAC) enhances the later security features and ensures a strong and mutual authentication of the TOE and the Inspection system. This step is required to access biometric data such as fingerprints and iris stored in DG3 and DG4. In particular, the authentication steps ensures a strong secure channel able to provide confidentiality of the biometric data that are read and authentication of the Inspection system retrieving the date to perform a Match on Terminal comparison. The Extended Access Control authentication steps the TOE implements may be performed either with elliptic curve cryptography, or with RSA cryptography. 2.2.5.5 Extended Access Protection (EAP) The Extended Access Protection (EAP) extends EAC to allow a more flexible protocol. It can protect up to 16 DGs (from 1 to 16) and is no more restricted to DG3 and 4. There is also no prerequisite to perform A BAP before starting EAP. In addition, it is possible to send more than 2 certificates to the TOE in order to gain extra access rights. 12 FQR 110 6669 Ed1 Following secure messaging can be either in 3DES or AES taking into account that if a BAP was previously performed algorithm used must be stronger2 . This feature is not in the TOE scope. 2.3 Chip and software composition The TOE contains an auto-programmable microcomputer (IC) with non-volatile EEPROM memory, permitting the storing of secret or confidential data, and with associated circuits that ensure its protection. The IC also integrates a ROM memory which embeds the code software of the smartcard. In order to ensure a secure composition between IC and software, the chip is configured and used according to the security requirements specified in the datasheet and associated guides. This especially specifies the secure way to manage IC memory. The optional code or “codop” is an executable code that is stored in the EEPROM of the chip. This code is called by the Resident Application when needed. These data are loaded during the pre- personalisation phase after the authentication of the manufacturer. Once an optional code is loaded, it is not possible to load any other optional code whether the TOE is in pre-personalisation phase or personalisation phase. The TOE ensures the optional code’s integrity and that it can not be read from the outside. In order to configure the available features of the product a One-Time Programmable (OTP) area is present (see 2.4). It can be written only once and cannot be erased afterward. Figure 2 Memory mapping of the TOE 2.4 TOE Configurations The application locks are within a particular area of the EEPROM memory. It is called OTP (One Time Programmable). When the TOE is delivered, all the bits of this area are set to ‘0’. Theses bits may be set (to “1”) in pre-personalisation phase or personalisation phase after the agent authentication (Manufacturer or Personnalizer). Once a bit is set to “1” in this area, it can not be reset anymore. This area is used to select the configuration of the TOE, in particular: • If the BAC is enforced in used phase (‘0’ = not enforced/’1’ = enforced) • If the EAC is enforced in used phase (‘0’ = not enforced/’1’ = enforced) • If the Get Data command is disabled (‘0’ = enabled/’1’ = disabled) • If the Active authentication is activated (‘0’ = not activated/’1’ = activated) 2 AES 256 is stronger than AES 192 which is stronger than AES 128 which is stronger than 3DES. ROM Executable code software EEPROM Data (File system) Codop area Memory adresses 13 FQR 110 6669 Ed1 • To indicate the TOE was pre-personalised (‘1’ = pre-personalised) • To indicate the TOE was personalised (‘1’ = personalized) These OTP bytes are protected in integrity as they are copied in EEPROM too. Final configuration of the product is set by activating one or several of the five first locks. The product is in use phase when the two last locks are activated. Since BAC is a configuration, the two ones have been merged into a unique lock. Note that in order to be functional, a correct and consistent personalisation of the TOE must be performed. 2.5 TOE logical structure Roughly, the embedded application, when powered, is seen as a master file, containing a Dedicated file (DF) for the LDS. This dedicated file is selected by means of the Application Identifier (AID) of the LDS application for example in case of ePassport. Once the application dedicated files are selected, the file structure it contains may be accessed, provided the access conditions are fulfilled. 2.5.1 File structure of the TOE Figure 3 : Structure of the file system 14 FQR 110 6669 Ed1 The TOE distinguish between two types of data • System files, • Data files that store data that are visible from the outside. Basically, system files and data files are files handled by the Resident Application. The Resident Application handles their creation and management. Both types have the following characteristics: • Size, size reserved within the EEPROM for the content of this file, • EF ID, Elementary File Identifier of the file within the file structure, • SFI, Short File Identifier used for an easy file selection. It is only used for data files, • Access conditions, it specify under which conditions the file may be accessed (read never, read always...). 2.5.2 System files System files are dedicated to store sensitive data that are used by the application. These data are protected in integrity by means of a checksum. Theses files may be created and updated in pre- personalisation or personalisation phase. Files containing keys are never readable. Once created, these files are used by the application to work properly. They have to be created before any use of the application. In particular, theses files are used to store: • The active authentication public key needed to perform the active authentication, • The active authentication private key needed to perform the active authentication, • The keys needed to perform BAC and EAC, • The list of the application present on the card. 2.5.3 Data files Data files also called Elementary files (EF) or Data Groups (DG) are dedicated to store data that may be retrieved. They are protected in integrity by means of a checksum and can be created or updated either in pre-personalisation or in personalisation phase. They are also created in such a way they can only be read or write in use phase, provided authentications specified in access rights are performed. All personalisation configurations are possible including BAC and EAC. Nevertheless, Data Files usually considered are the following: • EF.COM which describes which DGs are present in the file structure, • EF.SOD which contains a certificate computed over the whole DGs. It ensures their integrity & authenticity, • DG1 up to DG24 which contains information about the holder (picture, name…) and key required to perform authentications. 2.6 Non evaluated features Some features of the product are put out of the evaluation scope and are therefore not part of the TOE. Here is the complete list of those functionalities: • Supplemental Access Control, • Standard and biometric PIN management (therefore PIN associated commands are out of scope), • BAP and EAP applications 15 FQR 110 6669 Ed1 2.7 TOE life cycle The Smart card life-cycle considered hereby, is the one described in [R13]. This protection profile is decomposed into 7 phases, described hereafter, whose only first three ones defined the TOE evaluation scope. This life cycle is related to the different phases the designer/manufacturer/issuer has to go through to get a smart card ready to use. It starts from the design till the end of usage of the card. Note that [R10] and [R11] define an alternative lifecycle almost equivalent (phases in [R13] are steps in [R10] and [R11]) except this only difference: • Step 4 in [R10] and [R11], correspond to phase 4 of [R10] and [R11] and blocks ‘Micromodule”, “testing” and “Embedding” in phase 5 of [R10] and [R11], • Step 5 in [R10] and [R11] correspond to the only next blocks “Personnalisation” and “Testing” in phase 5 of [R10] and [R11].

The EAL4 have been augmented3 with the following requirements to fulfill the Oberthur Technologies assurance level: Requirement Name Type ALC_DVS.2 Sufficiency of security measures Higher hierarchical component ADV_FSP.5 Complete semi-formal functional specification with additional error information Higher hierarchical component ADV_INT.2 Well-structured internals New component ADV_TDS.4 Semiformal modular design Higher hierarchical component ALC_CMS.5 Development tools CM coverage Higher hierarchical component ALC_TAT.2 Compliance with implementation standards Higher hierarchical component ATE_DPT.3 Testing: modular design Higher hierarchical component Remark For interoperability reasons it is assumed the receiving state cares for sufficient measures against eavesdropping within the operating environment of the inspection systems. Otherwise the TOE may protect the confidentiality of some less sensitive assets (e.g. the personal data of the TOE holder which are also printed on the physical TOE) for some specific attacks only against enhanced basic attack potential (AVA_VAN.3). 3.3 Protection Profile conformance The Security Target claims strict conformance to the following PP written in CC3.1 revision 3: • Machine Readable Travel Documents with “ICAO Application”, Basic Access Control [R10]. 3 This EAL and its augmentations correspond to an EAL5+ALC_DVS.2 where AVA_VAN level is downgraded to AVA_VAN.3 following constraint of [R10] about MRZ/keydoc entropy. 18 FQR 110 6669 Ed1 4 Security problem definition 4.1 Assets Logical MRTD data The logical MRTD data consists of the EF.COM, EF.DG1 to EF.DG16 (with different security needs) and the Document Security Object EF.SOD according to LDS [R2]. 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 Active Authentication Public Key Info in DG 15 is used by the inspection system for Active Authentication of the chip. The Document security object is used by the inspection system for Passive Authentication of the logical MRTD. All these data may be sorted out in two different categories. o If they are specific to the user, they are User data, o If they ensures the correct behaviour of the application, they are TSF Data. User data CPLC Data Data uniquely identifying the chip. They are considered as user data as they enable to track the holder Personnal Data of the MRTD holder (EF.DGx, except EF.DG15) Contains identification data of the holder Document Security Object (SOD) in EF.SOD Contain a certicate ensuring the integrity of the file stored within the MRTD and their authenticity. It ensures the data are issued by a genuine country Common data in EF.COM Declare the data the travel document contains Active Authentication Public Key in EF.DG15 Contain public data enabling to authenticate the chip thanks to an active authentication 19 FQR 110 6669 Ed1 TSF data TOE_ID Data enabling to identify the TOE Personalisation Agent reference authentication Data Private key enabling to authenticate the Personalisation agent Basic Access Control (AC) Key Master keys used to established a trusted channel between the Basic Inspection Terminal and the travel document Active Authentication private key Private key the chip uses to perform an active authentication Session keys for the secure channel Session keys used to protect the communication in confidentiality and in integrity Life Cycle State Life Cycle state of the TOE 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. 4.2 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. T.Chip_ID Adverse action: An attacker trying to trace the movement of the MRTD by identifying remotely the MRTD"s chip by establishing or listening to communications through the contactless communication interface. Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance Asset: Anonymity of user T.Skimming Adverse action: An attacker imitates an inspection system trying to establish a communication to read the logical MRTD or parts of it via the contactless communication channel of the TOE. Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance. Asset: confidentiality of logical MRTD data. T.Eavesdropping Adverse action: An attacker is listening to an existing communication between the MRTD"s chip and an inspection system to gain the logical MRTD or parts of it. The inspection system uses the MRZ data printed on the MRTD data page but the attacker does not know these data in advance. Threat agent: having enhanced basic attack potential, not knowing the optically readable MRZ data printed on the MRTD data page in advance. Asset: confidentiality of logical MRTD data. 20 FQR 110 6669 Ed1 T.Forgery Adverse action: An attacker alters fraudulently the complete stored logical MRTD or any part of it including its security related data in order to deceive on an inspection system by means of the changed MRTD holder"s identity or biometric reference data. This threat comprises several attack scenarios of MRTD forgery. The attacker may alter the biographical data on the biographical data page of the passport book, in the printed MRZ and in the digital MRZ to claim another identity of the traveler. The attacker may alter the printed portrait and the digitized portrait to overcome the visual inspection of the inspection officer and the automated biometric authentication mechanism by face recognition. The attacker may alter the biometric reference data to defeat automated biometric authentication mechanism of the inspection system. The attacker may combine data groups of different logical MRTDs to create a new forged MRTD, e.g. the attacker writes the digitized portrait and optional biometric reference finger data read from the logical MRTD of a traveler into another MRTD"s chip leaving their digital MRZ unchanged to claim the identity of the holder this MRTD. The attacker may also copy the complete unchanged logical MRTD to another contactless chip. Threat agent: having enhanced basic attack potential, being in possession of one or more legitimate MRTDs. Asset: authenticity of logical MRTD data. T.Abuse-Func Adverse action: An attacker may use functions of the TOE which shall not be used in the phase "Operational Use" in order (i) to manipulate User Data, (ii) to manipulate (explore, bypass, deactivate or change) security features or functions of the TOE or (iii) to disclose or to manipulate TSF Data. This threat addresses the misuse of the functions for the initialization and the personalization in the operational state after delivery to MRTD holder. Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD. Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF. T.Information_Leakage Adverse action: An attacker may exploit information which is leaked from the TOE during its usage in order to disclose confidential TSF data. The information leakage may be inherent in the normal operation or caused by the attacker. Leakage may occur through emanations, variations in power consumption, I/O characteristics, clock frequency, or by changes in processing time requirements. This leakage may be interpreted as a covert channel transmission but is more closely related to measurement of operating parameters, which may be derived either from measurements of the contactless interface (emanation) or direct measurements (by contact to the chip still available even for a contactless chip) and can then be related to the specific operation being performed. Examples are the Differential Electromagnetic Analysis (DEMA) and the Differential Power Analysis (DPA). Moreover the attacker may try actively to enforce information leakage by fault injection (e.g. Differential Fault Analysis). Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD. Asset: confidentiality of logical MRTD and TSF data. T.Phys-Tamper Adverse action: An attacker may perform physical probing of the MRTD"s chip in order (i) to disclose TSF Data or (ii) to disclose/reconstruct the MRTD"s chip Embedded Software. An attacker may physically modify the MRTD"s chip in order to (i) modify security features or functions of the 21 FQR 110 6669 Ed1 MRTD"s chip, (ii) modify security functions of the MRTD"s chip Embedded Software, (iii) modify User Data or (iv) to modify TSF data. The physical tampering may be focused directly on the disclosure or manipulation of TOE User Data (e.g. the biometric reference data for the inspection system) or TSF Data (e.g. authentication key of the MRTD"s chip) or indirectly by preparation of the TOE to following attack methods by modification of security features (e.g. to enable information leakage through power analysis). Physical tampering requires direct interaction with the MRTD"s chip internals. Techniques commonly employed in IC failure analysis and IC reverse engineering efforts may be used. Before that, the hardware security mechanisms and layout characteristics need to be identified. Determination of software design including treatment of User Data and TSF Data may also be a pre-requisite. The modification may result in the deactivation of a security function. Changes of circuitry or data can be permanent or temporary. Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD. Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF. T.Malfunction Adverse action: An attacker may cause a malfunction of TSF or of the MRTD"s chip Embedded Software by applying environmental stress in order to (i) deactivate or modify security features or functions of the TOE or (ii) circumvent, deactivate or modify security functions of the MRTD"s chip Embedded Software. This may be achieved e.g. by operating the MRTD"s chip outside the normal operating conditions, exploiting errors in the MRTD"s chip Embedded Software or misusing administration function. To exploit these vulnerabilities an attacker needs information about the functional operation. Threat agent: having enhanced basic attack potential, being in possession of a legitimate MRTD. Asset: confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF. T.Counterfeit An attacker with high attack potential produces an unauthorized copy or reproduction of a genuine MRTD's chip to be used as part of a counterfeit MRTD. This violates the authenticity of the MRTD's chip used for authentication of a traveller by possession of a MRTD. The attacker may generate a new data set or extract completely or partially the data from a genuine MRTD's chip and copy them on another appropriate chip to imitate this genuine MRTD's chip. 4.3 Organisational Security Policies P.Manufact The Initialization Data are written by the IC Manufacturer to identify the IC uniquely. The MRTD Manufacturer writes the Pre-personalization Data which contains at least the Personalization Agent Key. P.Personalization The issuing State or Organization guarantees the correctness of the biographical data, the printed portrait and the digitized portrait, the biometric reference data and other data of the logical MRTD with respect to the MRTD holder. The personalization of the MRTD for the holder is performed by an agent authorized by the issuing State or Organization only. 22 FQR 110 6669 Ed1 P.Personal_Data The biographical data and their summary printed in the MRZ and stored on the MRTD"s chip (EF.DG1), the printed portrait and the digitized portrait (EF.DG2), the biometric reference data of finger(s) (EF.DG3), the biometric reference data of iris image(s) (EF.DG4)3 and data according to LDS (EF.DG5 to EF.DG13, EF.DG16) stored on the MRTD"s chip are personal data of the MRTD holder. These data groups are intended to be used only with agreement of the MRTD holder by inspection systems to which the MRTD is presented. The MRTD"s chip shall provide the possibility for the Basic Access Control to allow read access to these data only for terminals successfully authenticated based on knowledge of the Document Basic Access Keys as defined in [R2]. P.Sensitive_Data_Protection All the sensitive data are at least protected in integrity. The keys are protected in both integrity and confidentiality. P.Key_Function All the cryptographic routines are designed in such a way that they are protected against probing and do not cause any information leakage that may be used by an attacker. 4.4 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 It is assumed that appropriate functionality testing of the MRTD is used. It is assumed that security procedures are used during all manufacturing and test operations to maintain confidentiality and integrity of the MRTD and of its manufacturing and test data (to prevent any possible copy, modification, retention, theft or unauthorized use). A.MRTD_Delivery Procedures shall guarantee the control of the TOE delivery and storage process and conformance to its objectives: o Procedures shall ensure protection of TOE material/information under delivery and storage. o Procedures shall ensure that corrective actions are taken in case of improper operation in the delivery process and storage. o Procedures shall ensure that people dealing with the procedure for delivery have got the required skill. A.Pers_Agent The Personalization Agent ensures the correctness of(i) the logical MRTD with respect to the MRTD holder, (ii) the Document Basic Access Keys, (iii) the Chip Authentication Public Key (EF.DG14) if stored on the MRTD"s chip, and (iv) the Document Signer Public Key Certificate (if stored on the MRTD"s chip). The Personalization Agent signs the Document Security Object. The Personalization Agent bears the Personalization Agent Authentication to authenticate himself to the TOE by symmetric cryptographic mechanisms. 23 FQR 110 6669 Ed1 A.Insp_Sys The Inspection System is used by the border control officer of the receiving State (i) examining an MRTD presented by the traveler and verifying its authenticity and (ii) verifying the traveler as MRTD holder.

The Basic Inspection System reads the logical MRTD under Basic Access Control and performs the Passive Authentication to verify the logical MRTD. A.BAC-Keys The Document Basic Access Control Keys being generated and imported by the issuing State or Organization have to provide sufficient cryptographic strength. As a consequence of the "ICAO Doc 9303" [R2], 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. 24 FQR 110 6669 Ed1 5 Security Objectives 5.1 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 The TOE must ensure that the logical MRTD data in EF.DG1 to EF.DG16, the Document security object according to LDS [R2] and the TSF data can be written by authorized Personalization Agents only. The logical MRTD data in EF.DG1 to EF.DG16 and the TSF data may be written only during and cannot be changed after its personalization. The Document security object can be updated by authorized Personalization Agents if data in the data groups EF.DG 3 to EF.DG16 are added. OT.Data_Int 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 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. OT.Identification 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 during Phase 2 "Manufacturing" and Phase 3 "Personalization of the MRTD".

OT.Prot_Phys-Tamper 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 o 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 o 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) o manipulation of the hardware and its security features, as well as o controlled manipulation of memory contents (User Data, TSF Data) with a prior o reverse-engineering to understand the design and its properties and functions. OT.Prot_Malfunction The TOE must ensure its correct operation. The TOE must prevent its operation outside the normal operating conditions where reliability and secure operation has not been proven or tested. This is to prevent errors. The environmental conditions may include external energy (esp. electromagnetic) fields, voltage (on any contacts), clock frequency, or temperature. OT.Chip_Authenticity The TOE must support the Inspection Systems to verify the authenticity of the MRTD's chip. The TOE stores a RSA or ECC private key to prove its identity, and that is used in chip authentication.

It ensures that at any time, the following keys are never readable: o BAC keys o Active Authentication private key o Personalisation agent keys It controls access to the CPLC data as well: o It ensures the CPLC data can be read during the personalization phase o It ensures it can not be readable in free mode at the end of the personalization step Regarding the file structure: In the operational use: o The terminal can read user data, the Document Security Object, EF.COM only after BAC authentication and through a valid secure channel. In the personalisation phase o The personalisation agent can read all the data stored in the TOE after it is authenticated by the TOE (using its authentication keys). o The TOE is uniquely identified by a random number, generated at each reset. This unique identifier is called (PUPI) It ensures as well that no other part of the EEPROM can be accessed at anytime Access Control in writing This function controls access to write functions (in EEPROM) and enforces the security policy for data writing.

It ensures as well the CPLC data can not be written anymore once the TOE is personalized and that it is not possible to load an optional code or change the personnaliser authentication keys in personalization phase. Regarding the file structure In the operational use: It is not possible to create any files (system or data files). Furthermore, it is not possible to update any system files. However o the application data is still accessed internally by the application for its own needs In the personalisation phase o The personalisation agent can create and write through a valid secure channel all the data files it needs after it is authenticated by the TOE (using its authentication keys. 42 FQR 110 6669 Ed1 BAC mechanism This security functionality ensures the BAC is correctly performed. It can only be performed once the TOE is personalized with the symmetric BAC keys the Personalization Agent loaded beforehand during the personalization phase. Furthermore, this security functionalities ensures the session keys are destroyed at the beginning of each BAC session. A self-test on TDES and random generator is performed when a BAC session is requested. Secure Messaging This security functionality ensures the confidentiality & integrity of the channel the TOE and the IFD are using to communicate. After a successful BAC authentication, a secure channel is established based on Triple DES algorithms. This security functionality ensures o No commands were inserted nor deleted within the data flow o No commands were modified o The data exchanged remain confidential o The issuer of the incoming commands and the destinatory of the outgoing data is the one that was authenticated (through BAC) If an error occurs in the secure messaging layer, the session keys are destroyed Personalisation Agent Authentication This security functionality ensures the TOE, when delivered to the Personnalization Agent, demands an authentication prior to any data exchange. This authentication is based on a symmetric Authentication mechanism based on a Triple DES or AES algorithm. Active Authentication This security functionality ensures the Active Authentication is performed as described in [R2]. (if it is activated by the personnalizer). A self-test on the random generator is performed priori to any Active authentication. Moreover, this security functionality is protected against the DFA. Self tests The TOE performs self tests on the TSF data it stores to protect the TOE. In particular, it is in charge of the: o DFA detection for the Active authentication o Self tests of the random generator before the BAC and Active Authentication o Self tests of the DES before the BAC Monitoring of the integrity of keys, files and TSF data Monitoring the integrity of the optional code (at start up) Protecting the cryptographic operation The integrity of the files are monitored each time they are accessed and the integrity of the optional code is checked each time the TOE is powered on. The integrity of keys and sensitive data is checked each time they are used/accessed. Safe state management This security functionalities ensures that the TOE gets bask to a secure state when o an integrity error is detected by F.SELFTESTS o a tearing occurs (during a copy of data in EEPROM) This security functionality ensures that such a case occurs, the TOE is either switched in the state "kill card" or becomes mute. 43 FQR 110 6669 Ed1 Physical protection This security functionality protects the TOE against physical attacks. Prepersonalisation This function is in charge of pre-initializing the product and loading patch code if needed. 8.2 Link between the SFR and the TSF Access Control in reading Access Control in writing BAC mechanism Secure Messaging PA Authentication Active Authentication Self tests Safe state management Physical protection Prepersonalisation FAU_SAS.1 X X FCS_CKM.1 X FCS_CKM.4 X X FCS_COP.1/SHA X X X X FCS_COP.1/ENC X X X X FCS_COP.1/AUTH X X X FCS_COP.1/MAC X X X FCS_RND.1 X X X X X X FIA_AFL.1 X FIA_UID.1 X X X X FIA_UAU.1 X X X FIA_UAU.4 X X X FIA_UAU.5 X X X FIA_UAU.6 X X X FDP_ACC.1 X X X FDP_ACF.1 X X X FDP_UCT.1 X X FDP_UIT.1 X X FMT_SMF.1 X X X X FMT_SMR.1 X FMT_LIM.1 X X FMT_LIM.2 X X 44 FQR 110 6669 Ed1 Access Control in reading Access Control in writing BAC mechanism Secure Messaging PA Authentication Active Authentication Self tests Safe state management Physical protection Prepersonalisation FMT_MTD.1/INI_ENA X X X FMT_MTD.1/INI_DIS X FMT_MTD.1/KEY_WRITE X X FMT_MTD.1/KEY_READ X X FPT_EMS.1 X X X X FPT_FLS.1* X FPT_TST.1 X FPT_PHP.3 X FDP_DAU.1/AA X FCS_COP.1/SIG_MRTD X X FDP_ITC.1/AA X X FMT_MOF.1/AA X FCS_CKM.1/ASYM X 45 FQR 110 6669 Ed1 9 References MRTD specifications [R1] Machine Readable Travel Documents Technical Report, PKI for Machine Readable Travel Documents Offering ICC Read-Only Access, Version - 1.1, Date - October 01, 2004, published by authority of the secretary general, International Civil Aviation Organization [R2] ICAO Doc 9303, Machine Readable Travel Documents, part 1 – Machine Readable Passports, Sixth Edition, 2006, International Civil Aviation Organization [R3] Development of a logical data structure – LDS for optional capacity expansion technologies Machine Readable Travel Documents Technical Report, Development of a Logical Data Structure – LDS, For Optional Capacity Expansion Technologies, Revision – 1.7, published by authority of the secretary general, International Civil Aviation Organization, LDS 1.7, 2004-05-18 [R4] Advanced Security Mechanisms for Machine readable travel documents – Extended Access control (EAC) – TR03110 – v1.11 [R5] Annex to Section III Security Standards for Machine Readable Travel Documents Excerpts from ICAO Doc 9303, Part 1 - Machine Readable Passports, Fifth Edition – 2003 IDL specifications [R6] Information Technology - Personal Identification — ISO Compliant Driving Licence — Part 1:Physical characteristics and basic data set, ISO/IEC FDIS 18013-1:2005(E) [R7] Information Technology - Personal Identification — ISO Compliant Driving Licence — Part 2: Machine-readable technologies, ISO/IEC FDIS 18013-2:2007(E) [R8] Personal Identification — ISO Compliant Driving Licence — Part 3: Access control, authentication and integrity validation, ISO/IEC FDIS 18013-3:2008(E) Protection Profiles [R9] Smartcard IC Platform Protection Profile v 1.0 - BSI-PP-0035 15/06/2007 [R10] Machine readable travel documents with “ICAO Application”, Basic Access control – BSI- PP-0055 v1.10 25th march 2009 [R11] Machine readable travel documents with “ICAO Application”, Extended Access control – BSI-PP-0056 v1.10 25th march 2009 [R12] E-passport: adaptation and interpretation of e-passport Protection Profiles, SGDN/DCSSI/SDR, ref. 10.0.1, February 2007 [R13] Embedded Software for Smart Security Devices, Basic and Extended Configurations, ANSSi-CC-PP-2009/02, 1/12/2009 Security Target [R14] NXP Secure Smart Card Controllers P5CD016/021/041V1A and P5Cc081VIA Security Target Lite, BSI-DSZ-0555, Rev. 1.3, 21 September 2009 Standards [R15] ISO7816-4 – Organization, security and commands for interchange 46 FQR 110 6669 Ed1 [R16] Technical Guideline: Elliptic Curve Cryptography according to ISO 15946.TR-ECC, BSI 2006 [R17] ISO/IEC 15946-1.
