INTRODUCTION This Security Target Lite aims to satisfy the requirements of Common Criteria level EAL5+, augmented with AVA_VAN.5 and ALC_DVS.2 in defining the security enforcing functions of the Target Of Evaluation and describing the environment in which it operates. The basis for this composite evaluation is the composite evaluation of Open Platforms COSMOV8.1-N - Platform and configurable JavaCard application, Taiwan eID Applet CC. The Taiwan eID Applet CC is a custom version of the LDS V10. Some configurations of the applet use a shared library with HICOS application. The Taiwan eID Applet CC can have different configurations, the presents ST considers the configuration and does not use the shared library with HICOS application:  EAC V2 with PACE-CAM/TA without CA  AA The Taiwan eID Applet CC application code is loaded on the E2Prom of the platform at prepersonalisation or personalisation phase. The applet works on 2 platforms: The first is ID-One Cosmo v8.1-N - Standard Platform’, embeds the PIV 2.4 Application in ROM. The second platform, ‘ID-One Cosmo v8.1-N Large Platform’ embeds the applications PIV 2.4 and IAS ECC V2 Applications in ROM. A new version of the ID-One Cosmo v8.1-N Large platform (ID-One Cosmo v8.1-N R2 Large) also embeds the Taiwan eID Applet CC application in ROM. The 2 platforms have the same interfaces and covered by a unique security target [54]. All additional applications, romed or loaded in E2prom at pre perso or perso phase are out of the scope of the present evaluation, for example PIV2, IAS ECC V2. 1.1.

Required non-TOE hardware/software/firmware The TOE is an MRTD. It is an independent product and does not need any additional hardware/software/firmware to ensure its security. In order to be powered up and to be able to communicate the TOE needs a card reader. 2.1.3. TOE Usage and major security features 25 | 87 State or organisation issues MRTDs to be used by the holder to prove his/her identity and claiming associated rights. For instance, it can be used to check identity at customs in an MRTD configuration, verifying authenticity of electronic visa stored on the card and correspondence with the holder. In order to pass successfully the control, the holder presents its personal MRTD to the inspection system to first prove his/her identity. The inspection system is under control of an authorised agent and can be either a desktop device such as those present in airports or a portable device to be used on the field. The MRTD in context of this security target contains: Visual (eye readable) biographical data and portrait of the holder printed in the booklet A separate data summary (MRZ or keydoc data) for visual and machine reading using OCR methods in the Machine Readable Zone (MRZ or keydoc area) And data elements stored on the TOE’s chip for contact-less machine reading. The authentication of the holder is based on: The possession of a valid MRTD personalized for a holder with the claimed identity as given on the biographical data page and The Biometric matching performed on the Inspection system using the reference data stored in the MRTD. When holder has been authenticated the issuing State or Organization can performed extra authentications in order to gain rights required to grant access to some sensitive information such as “visa information”… The issuing State or Organization ensures the authenticity of the data of genuine MRTDs. The receiving State trusts a genuine MRTD of an issuing State or Organization. The MRTD can be viewed as the combination: A physical MRTD in form of paper or plastic with an embedded chip and possibly an antenna. It presents visual readable data including (but not limited to) - Personal data of the MRTD holder - The biographical data on the biographical data page of the passport book - The printed data in the Machine-Readable Zone (MRZ) or keydoc area that identifies the device - The printed portrait A logical MRTD as data of the MRTD holder stored according to the Logical Data Structure as specified by ICAO and extended in [44][45][46] on the contactless integrated circuit. It presents contact or contact-less readable data including (but not limited to) - Personal data of the MRTD holder - The digital Machine Readable Zone Data (digital MRZ data or keydoc data, DG1) - The digitized portraits - The optional biometric reference data of finger(s) or iris image(s) or both - The other data according to LDS (up to DG24) - The Document security object The issuing State or Organization implements security features of the MRTD to maintain the authenticity and integrity of the MRTD and its data. The MRTD as the physical device and the MRTD’s chip is uniquely identified by the document number. The physical MRTD is protected by physical security measures (e.g. watermark on paper, security printing), logical (e.g. authentication keys of the MRTD’s chip) and organisational security measures (e.g. control of materials, personalization procedures). These security measures include the binding of the MRTD’s chip to the physical support. 26 | 87 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. 2.2. TOE Definition The Target of Evaluation (TOE) is the contactless integrated circuit chip of machine readable travel documents (MRTD’s chip) programmed according to the Logical Data Structure (LDS) and providing and provides standard authentication protocols, namely Basic Access Control, Extended Access Control and Active Authentication. The product can be configured to serve different use cases, during the Prepersonalization/personalization phases of the product. The TOE comprises at least: - Circuitry of the MRTD’s chip (the integrated circuit, IC) - IC Dedicated Software with the parts IC Dedicated Test Software and IC Dedicated Support Software - Cosmo V8-1N Standard or Large - API - Taiwan eID Applet CC application - Associated guidance documentation The platform provides an operational environment for the application: all cryptographic algorithm implementations and associated self-tests, random number and key generation, card lifecycle management, and key storage and protection are provided by the platform. The code for this functionality is contained in the platform ROM. However, the factory configuration of the module constrains the module to the set of services provided by the platform’s Card Manager (implementing a standard set of GlobalPlatform services), Some applications present on the Cosmo v8.1-N Platform are not usable on this TOE such as the PIV applet which is not instantiated. The applet may be used on a contact mode compliant to ISO/IEC 7816-3 specification or on contactless mode compliant to ISO/IEC 14443 specification. 2.3. TOE Architecture The TOE is a smartcard, composed of IC, Javacard Platform and the Taiwan eID Applet CC application. Other applications may reside in the TOE. 2.3.1. Integrated Circuit The TOE is embedded on NXP chips, more information on the chips is given in the related public Security Targets lites identified in table 3 of chapter 1.3.2. 2.3.2. JavaCard Platform The Operating System is based on Java Card Technology and Global Platform technology. His main responsibilities are:  providing interface between the Integrated Circuit and the applet  providing to the applet, basic services to access to memories and all needed cryptographic operations  ensuring global management of the card (loading, installation and deletion of applets) and monitor the security of the card (data integrity and physical attacks counter-measures). For details see [54]. 27 | 87 2.3.3. Application Functionalities This application stores the personal information related to the cardholder of an MRTD or an IDL. It also allows governmental organizations to retrieve these pieces of data. The applet supports the authentication mechanisms described in ICAO and EAC specifications and ISO/IEC 18013-3 ISO Compliant Driving License specification with a fully configurable access control management over the EFs (EFs). The applet may be used on a contact mode (compliant to ISO/IEC 7816-3 specification) and/or contactless mode (compliant to ISO/IEC 14443 specification). The compliancy of the applet to LDS, EAC, or IDL, is achieved provided a correct personalization is performed. The correct authentication mechanisms and access conditions over the EFs must be assigned. In summary, the applet supports the following authentication mechanisms stated in the ICAO specifications (for MRTD) and the ISO Compliant Driving License standard (for IDL): • Active Authentication (AA) • Basic Access Control (BAC) • Password Authenticated Connection Establishment (PACE) • Extended Access Control (EAC) • Chip Authentication Mapping (CAM) All authentication mechanisms are listed in the following chapters, all are part of the product but only some are part of the present evaluation. 2.3.3.1. Active Authentication (AA) Active Authentication is an authentication mechanism ensuring the chip is genuine. It uses a challenge- response protocol between the IS and the chip. Active Authentication is realized with the INTERNAL AUTHENTICATE command. The key and algorithms supported are the following: - RSA ISO/IEC 9796-2 with a key length of 1024 bits, 1536 bits or 2048 bits and hashing algorithm of SHA1 or SHA2. - ECDSA over prime field curves with hashing algorithm of SHA1 or SHA2 and the key sizes 192 to 512. - AES-256 using ISO/IEC 9797-1 M2 padding method. - TDES with double and triple length keys using ISO/IEC 9797-1 M2 padding method. 2.3.3.2. Basic Access Control (BAC) The protocol for Basic Access Control is specified by ICAO [47] Basic Access Control checks that the terminal has physical access to the MRTD’s data page. This is enforced by requiring the terminal to derive an authentication key from the optically read MRZ of the MRTD. The protocol for Basic Access Control is based on ISO/IEC 11770-2 [41] key establishment mechanism 6. This protocol is also used to generate session keys that are used to protect the confidentiality (and integrity) of the transmitted data. The Basic Access Control (BAC) is a security feature that is supported by the TOE. The inspection system: - Reads the printed data in the MRZ (for MRTD), - Authenticates itself as inspection system by means of keys derived from MRZ data. After successful 3DES based authentication, the TOE provides read access to data requiring BAC rights by means of a private communication (secure messaging) with the inspection system. 28 | 87 The purpose of this mechanism is to ensure that the holder gives access to the IS to the logical MRTD (data stored in the chip); It is achieved by a mutual authentication. Once the mutual authentication is performed, a secure messaging is available to protect the communication between the chip and the IS. This table lists the supported configurations for BAC protocol: Configuration Key Algo Key Length Hash Algo MAC Algo BAC 3DES 2Key 16-bytes SHA-1 Retail MAC Table 7: BAC Configuration 2.3.3.3. Terminal Authentication The Terminal Authentication Protocol is a two move challenge-response protocol that provides explicit unilateral authentication of the terminal. This protocol enables the MRTD chip to verify that the terminal is entitled to access sensitive data. As the terminal may access sensitive data afterwards, all further communication MUST be protected appropriately. Terminal Authentication therefore also authenticates an ephemeral public key chosen by the terminal that was used to set up Secure Messaging with Chip Authentication. The MRTD chip MUST bind the terminal’s access rights to Secure Messaging established by the authenticated ephemeral public key of the terminal. 2.3.3.4. Chip Authentication The Chip Authentication Protocol is an ephemeral-static Diffie-Hellman key agreement protocol that provides secure communication and unilateral authentication of the MRTD chip. The protocol establishes Secure Messaging between an MRTD chip and a terminal based on a static key pair stored on the MRTD chip. Chip Authentication is an alternative to the optional ICAO Active Authentication, i.e. it enables the terminal to verify that the MRTD chip is genuine but has two advantages over the original protocol: Challenge Semantics are prevented because the transcripts produced by this protocol are non- transferable. Besides authentication of the MRTD chip this protocol also provides strong session keys. The protocol in version 1 provides implicit authentication of both the MRTD chip itself and the stored data by performing Secure Messaging using the new session keys. The protocol in Version 2 provides explicit authentication of the MRTD chip by verifying the authentication token and implicit authentication of the stored data by performing Secure Messaging using the new session keys. 2.3.3.5. Password Authenticated Connection Establishment (PACE) PACE is an access control mechanism that is supplemental to BAC. It is a cryptographically stronger access control mechanism than BAC since it uses asymmetric cryptography compared to BAC’s symmetric cryptography. PACE is realized through 5 commands: 1. MSE SET – AT command 2. GENERAL AUTHENTICATE command – Encrypted Nonce 3. GENERAL AUTHENTICATE command – Map Nonce 4. GENERAL AUTHENTICATE command – Perform Key Agreement 5. GENERAL AUTHENTICATE command – Mutual Authentication 29 | 87 Once the mutual authentication is performed, a secure messaging is available to protect the communication between the chip and the IS. This table lists the supported configurations for PACE protocol: Configuration Mapping Key Algo Key Length (in bytes) Secure Messaging Auth.

Extended Access Control (EAC) EAC is an authentication protocol based on a PKI infrastructure. It further ensures that the IS is authorized to read and/or update data stored in the applet. This authentication mechanism generates a strong secure messaging session through the step of Chip Authentication. This mechanism is realized by the following steps: 1. Chip Authentication (CA)Chip Authentication is achieved by using a MANAGE SECURITY ENVIRONMENT – SET – Key Agreement Template (MSE SET KAT) command or by using a MANAGE SECURITY ENVIRONMENT – SET – Authentication Template (MSE SET AT) command followed by GENERAL AUTHENTICATE command. The Chip Authentication mechanism enables the authentication of the chip by using an authenticated DH scheme. It may be realized in two ways:  Classical DH (DH El Gamal) with key length of 1024, 1536, or 2048 bits  DH over Elliptic curves over prime fields (ECDH) with the key length supported by the underlying Javacard platform. 2. Certificate Chain Handling The certificate chain is processed through a series of MANAGE SECURITY ENVIRONMENT – SET – Digital Signature Template (MSE SET DST) and PERFORM SECURITY OPERATION – Verify Certificate (PSO VERIFY) commands. 30 | 87 The chain is done to extract a key from the IS certificate, the key which will be used in the Terminal Authentication. 3. Terminal Authentication (TA) Terminal Authentication is achieved by using an EXTERNAL AUTHENTICATE command. The Terminal Authentication mechanism is an authentication of the IS based on a classical challenge/response scheme. The signature scheme may be: ECDSA SHA-1, ECDSA SHA-224, ECDSA SHA-256, ECDSA SHA-384, or ECDSA SHA-512 on elliptic curves over prime field with key length supported by the underlying Javacard platform RSA SHA-1, SHA-256, or SHA-512 (PKCS#1 v1.5 or PKCS#1 v2.1 - PSS) with a key length of 1024, 1536, and 2048 bits. 2.3.3.7. PACE-CAM The Chip Authentication Mapping is a new mapping for PACE which extends the Generic Mapping that integrates Chip Authentication into the PACE protocol. This mapping combines PACE and Chip Authentication into one protocol PACE-CAM, which allows faster execution than the separate protocols (i.e. PACE + CA + TA). PACE-CAM is realized the same way as § 2.3.3.6. The only difference is that the chip computes the Chip Authentication Data using the chip’s static private key then sends this data to the terminal. The terminal verifies the authenticity of the chip using the recovered Chip Authentication Data. 2.3.3.8. Match On-Card (MOC) Verification MOC verification may be used to grant some access rights to EFs. This feature relies on the services provided by the CHV Server applet MOC verification is supported if the CHV Configuration is properly configured in the install parameter. Once the MOC verification is allowed the applet will permit the use of CHV-related commands that handles biometric and Global PIN credentials. 2.3.3.9. PIN The product supports the management of card holder credentials such as Cardholder PIN and Global PIN which can be used to grant access rights to EFs or keys. The Cardholder PIN and Global PIN each have its PIN Unblocking Key (Cardholder PUK and Global PUK, respectively). These PINs and corresponding PUKs have to be initialized during personalization if they are used to pdrotect access to EFs and keys. 2.3.3.10. Watermarking The watermarking feature may be used to restrict the access to the plain image data of particular EF(s). Enabling the watermarking will cause the image data to be corrupted during the reading of the file contents. The de-watermarking conditions should be configured accordingly and these conditions must be satisfied in order to grant access to the plain image data, details are in the dedicated security Target. 2.3.3.11. Secure Messaging The TOE supports the ISO Secure Messaging. It provides a secure channel (i.e. encrypted and authenticated) between application and terminal. Secure Messaging can be set up by Chip Authentication, PACE, or Basic Access Control. The provided security level depends on the mechanism used to set up Secure Messaging. A session is started when secure messaging is established. The session only ends with the release of 31 | 87 secure messaging, e.g. by sending a command without secure messaging. 2.3.3.12. OT Cryptographic library A dedicated cryptographic library has been developed and designed by Oberthur Technologies. This cryptographic library is embedded on the TOE to provide the highest security level and best tuned performances. It is implemented at the platform level and are already in the scope of the platform evaluation. 2.3.3.13. Additional applications Additional java card applications are present in the TOE: PIV 2.4 and IAS ECC V2, … These applications are outside the scope of the present evaluation. 2.3.4. Mechanism included in the scope of the evaluation All TOE functionalities are presented in the previous chapter. The present evaluation includes the listed functionalities:  EAC  AA  CAM  BAC deactivation (additional function)  Secure Messaging (DES + AES) on read DG3+DG4 after EAC  Personalization functions 2.4.

TOE LIFE CYCLE 3.1. TOE Life Cycle Overview Figure 3: Smartcard product life-cycle for the TOE The TOE life-cycle classically described in terms of four life-cycle phases, is additionally subdivided into 7 steps. The roles involved in the different steps are listed in the following table: Roles Subjects IC manufacturer NXP Semiconductors TOE developer Oberthur Technologies Manufacturer NXP Semiconductors Phase 1 a), b) Phase 2 a) Phase 3 Phase 4 Testing Phase 5 b) Testing Testing Phase 6 Phase 7 ALC phase AGD phase USE phase AGD PRE TOE delivery point in case of a) Software development IC photomask fabrication IC database construction IC manufacturing Card printing Micromodule Embedding Prepersonalization Personnalisation Smartcard product End usage Application End usage Smartcard End of life Application End of life IC testing AGD OPE Code of MRTD application loading: ROM or E2PROM 33 | 87 Oberthur Technologies or another agent Prepersonalizer Oberthur Technologies or another agent Personalization Agent Oberthur Technologies or another agent Table 10: Roles Identification on the life cycle. 3.2. TOE Life Cycle when the Application code is romed The table below presents the subjects following TOE life cycle steps in accordance with the standard smart card life cycle, the Protection Profile lifecycle in phases, the TOE delivery point and the coverage in the case a). Steps Phase Subject Covered by Sites Step 1 Development Oberthur Technologies ALC R&D sites -Pessac and Colombes for platform and -Manille for Taiwan eID Applet CC application development Step 2 Development NXP Semiconductors IC certification IC certification Step 3 Manufacturing NXP Semiconductors IC certification IC certification TOE delivery point Step 4 Manufacturing MRD Manufacturer (Prepersonalizer) AGD_PRE Step 5 Manufacturing MRD Manufacturer (Prepersonalizer) AGD_PRE Step 6 Personalization Personalization Agent AGD_PRE Step 7 Operational Use End user AGD_OPE Table 11: Subjects identification following life cycle steps Details for each phase/step are presented in the following paragraphs. 3.3. Phase 1 “Development” (Step1) The TOE is developed in phase 1. The IC developer develops the integrated circuit, the IC Dedicated Software and the guidance documentation associated with these TOE components. The TOE includes the Taiwan eID Applet CC application and the Platform. The LDS is developed at Manille and the platform at Colombes and Pessac. The sites are audited following MSSR last requirements. (Step2) The TOE developer uses the guidance documentation for the integrated circuit and the guidance documentation for relevant parts of the IC Dedicated Software and develops the IC Embedded Software (operating system), the MRTD application and the guidance documentation associated with these TOE components. The manufacturing documentation of the IC including the IC Dedicated Software and the Embedded Software in the non-volatile non-programmable memories is securely delivered to the IC manufacturer. The IC Embedded Software in the non-volatile programmable memories, the eMRTD application and the guidance documentation is securely delivered to the Manufacturer. 3.4. Phase 2 “Manufacturing” (Step3) In a first step the TOE integrated circuit is produced containing the travel document’s chip Dedicated Software and the parts of the travel document’s chip Embedded Software in the non-volatile 34 | 87 non-programmable memories (ROM). The IC manufacturer writes the IC Identification Data onto the chip to control the IC as travel document material during the IC manufacturing and the delivery process to the Manufacturer. The IC is securely delivered from the IC manufacture to the Manufacturer. If necessary the IC manufacturer adds the parts of the IC Embedded Software in the non-volatile programmable memories (for instance EEPROM). The IC manufacturer adds initialization data in EEPROM and keys (MSK, LSK). The end of step 3 is the TOE delivery. (Step4) The Manufacturer combines the IC with hardware for the contact based / contactless interface in the travel document unless the travel document consists of the card only. (Step5) The Manufacturer (i) adds the IC Embedded Software (ii) creates the eMRTD application, and (iii) equips travel document’s chips with pre-personalization Data. The pre-personalised travel document together with the IC Identifier is securely delivered from the Manufacturer to the Personalization Agent. The Manufacturer also provides the relevant parts of the guidance documentation to the Personalization Agent. 3.5. Phase 3 “Personalization of the travel document” (Step6) The personalization of the travel document includes: (i) the survey of the travel document holder’s biographical data, (ii) the enrolment of the travel document holder biometric reference data (i.e. the digitized portraits and the optional biometric reference data), (iii) the personalization of the visual readable data onto the physical part of the travel document, (iv) the writing of the TOE User Data and TSF Data into the logical travel document and (v) configuration of the TSF if necessary. The step (iv) is performed by the Personalization Agent and includes but is not limited to the creation of (i) the digital MRZ data (EF.DG1), (ii) the digitized portrait (EF.DG2), and (iii) the Document security object. The signing of the Document security object by the Document signer finalizes the personalization of the genuine travel document for the travel document holder. The personalised travel document (together with appropriate guidance for TOE use if necessary) is handed over to the travel document holder for operational use. 3.5.1. Loading of application The platform can host 2 kinds of applications: Evaluated sensitive applications and validated basic applications. Once the application is evaluated or validated, it is securely delivered to manufacturing site. This delivery ensures the integrity and confidentiality of the application code and data. Then applications code and data are securely stored. The delivery, storage and loading of any application are covered by audited Organisational measures (ALC). Applications can be loaded at pre issuance at step 5 or at step 6 or in post issuance. 3.5.2. Applet pre-personalisation (phase 6) This phase is performed by the Personalisation Agent, which controls the TOE. During this phase, the javacard applet is prepared as required by P.TOE_Construction. All along this phase, the TOE is self-protected as it requires the authentication of the Personalisation Agent prior to any operation. 3.5.3. TOE personalisation (phase 6) 35 | 87 This phase is performed by the Personalisation Agent, which controls the TOE, which is in charge of the javacard applet personalisation. All along this phase, the TOE is self-protected as it requires the authentication of the Personalisation Agent prior to any operation. This phase may not necessarily take place in a manufacturing site, but may be performed anywhere. The Personalisation Agent is responsible for ensuring a sufficient level of security during this phase. The javacard applet is personalized according to guidance document [57]. At the end of phase 6, the TOE is constructed. 3.6. Phase 4 “Operational Use” (Step7) The TOE is used as a travel document's chip by the traveller and the inspection systems in the “Operational Use” phase. The user data can be read according to the security policy of the issuing State or Organisation and can be used according to the security policy of the issuing State but they can never be modified. Note that the personalization process and its environment may depend on specific security needs of an issuing State or Organisation. All production, generation and installation procedures after TOE delivery up to the “Operational Use” (phase 4) have to be considered in the product evaluation process under AGD assurance class. Therefore, the Security Target has to outline the split up of P.Manufact, P.Personalization and the related security objectives into aspects relevant before vs. after TOE delivery. Some production steps, e.g. Step 4 in Phase 2 may also take place in the Phase 3. 3.7.

The Manufacturer also provides the relevant parts of the guidance documentation to the Personalization Agent (AGD_PRE). When the Taiwan eID Applet CC application is loaded on the Platform at Phase 6; the entity responsible of the loading is the Personalization Agent:  The Personalization Agent (phase 6) loads the Taiwan eID Applet CC application code (ii) creates the eMRTD application, and (iii) equips travel document’s chips with pre- personalization Data.  The MRTD is also personalized, in this step, as defined in the chapter 3.5.3.  The personalization phase can also occur in phase 7, by the Issuer. When the Taiwan eID Applet CC application is loaded on the Platform at Phase 7; the entity responsible of the loading is the issuer, the Prepersonalization and the personalisation of the MRTD is under the Issuer responsibility. All required information is securely given (application code and AGD_PRE and AGD_OPE).

Overview of the additional protocols 4.3.4.1. Active Authentication The additional functionality of Active Authentication (AA) is based on the ICAO PKI V1.1 and the related on-card generation of RSA and ECC keys. It implies the following addition to the standard PP: - Additional Threats: § 5.3.2 - Additional Objective: § 6.1.2 - Additional OSP: § 5.4.2 - Additional Assumptions: § 5.5.2 4.3.4.2. Prepersonalization phase The prepersonalization phase has been reinforced in this Security Target, with the following elements. This functionality is usable in phase 5 and phase 6. Once the product is locked, stated as personalized, it is no more possible to perform this operation. 4.3.5. Rationale for the additions In order to be compliant with the CEM, a rationale is given for the additional Objectives on the Environment, such as to demonstrate that they neither mitigates a threat or fulfil an OSP. 4.3.5.1. OE for AA rationale The objectives OE.Exam_MRTD_AA, OE.Prot_Logical_MRTD_AA, OE.Activ_Auth_Verif and OE.Activ_Auth_Sign define additional requirements on the operational environment for the Active Authentication Protocol which is not in the original scope of the PP BAC. This OE is only linked to threat and OSP for the Active Authentication and has no links with those of the PP. 4.3.5.2. Assumption for AA rationale The A.Insp_Sys_AA is added, this assumption is only linked to Active Authentication mechanism as the Inspection System has to implement the mechanism and shall verify the authenticity of the MRTD’s chip during inspection using the signature returned by the TOE during Active Authentication. 43 | 87 5.

It corresponds to the MRTD manufacturer) x Table 24: Subjects and phases 5.1.1. PP EAC Manufacturer Generic term for the IC Manufacturer producing integrated circuit and the travel document Manufacturer completing the IC to the travel document. The Manufacturer is the default user of the TOE during the manufacturing life cycle phase. The TOE itself does not distinguish between the IC Manufacturer and travel document Manufacturer using this role Manufacturer. This entity is commensurate with ‘Manufacturer’ in [47]. Personalisation Agent An organisation acting on behalf of the travel document Issuer to personalise the travel document for the travel document holder by some or all of the following activities:  Establishing the identity of the travel document holder for the biographic data in the travel document  Enrolling the biometric reference data of the travel document holder  Writing a subset of these data on the physical travel document (optical personalisation) and storing them in the travel document (electronic personalisation) for the travel document holder as defined in [43]  Writing the document details data  Writing the initial TSF data  Signing the Document Security Object defined in [43] (in the role of DS). Please note that the role ‘Personalisation Agent’ may be distributed among several institutions according to the operational policy of the travel document Issuer. This entity is commensurate with ‘Personalisation agent’ in [47]. 44 | 87 Application Note Personalization Agent is refered as the Personalizer in the Security Target Document Verifier The Document Verifier (DV) enforces the privacy policy of the receiving State with respect to the protection of sensitive biometric reference data to be handled by the Extended Inspection Systems. The Document Verifier manages the authorization of the Extended Inspection Systems for the sensitive data of the MRTD in the limits provided by the issuing States or Organizations in the form of the Document Verifier Certificates. Terminal A terminal is any technical system communicating with the TOE either through the contact interface or through the contactless interface. Inspection System (IS) A technical system used by the border control officer of the receiving State (i) examining an MRTD presented by the traveler and verifying its authenticity and (ii) verifying the traveler as MRTD holder. The Basic Inspection System (BIS) (i) contains a terminal for the contactless communication with the MRTD’s chip, (ii) implements the terminals part of the Basic Access Control Mechanism and (iii) gets the authorization to read the logical MRTD under the Basic Access Control by optical reading the MRTD or other parts of the passport book providing this information. The General Inspection System (GIS) is a Basic Inspection System which implements additionally the Chip Authentication Mechanism. The Extended Inspection System (EIS) in addition to the General Inspection System (i) implements the Terminal Authentication Protocol and (ii) is authorized by the issuing State or Organization through the Document Verifier of the receiving State to read the sensitive biometric reference data. The security attributes of the EIS are defined of the Inspection System Certificates. Country Verifying Certification Authority (CVCA) The Country Verifying Certification Authority (CVCA) enforces the privacy policy of the issuing State or Organization with respect to the protection of sensitive biometric reference data stored in the MRTD. The CVCA represents the country specific root of the PKI of Inspection Systems and creates the Document Verifier Certificates within this PKI. The updates of the public key of the CVCA are distributed in the form of Country Verifying CA Link-Certificates. Travel document holder (MRTD holder) A person for whom the travel document Issuer has personalised the travel document. This entity is commensurate with ‘MRTD Holder’ in [47]. Please note that a travel document holder can also be an attacker. Travel document presenter (Traveler) A person presenting the travel document to a terminal and claiming the identity of the travel document holder. This external entity is commensurate with ‘Traveller’ in [47]. Please note that a travel document presenter can also be an attacker (s. below). Attacker A threat agent (a person or a process acting on his behalf) trying to undermine the security policy defined by the current PP, especially to change properties of the assets having to be maintained. The attacker is assumed to possess an at most high attack potential. Please note that the attacker might ‘capture’ any subject role recognised by the TOE. This external entity is commensurate with ‘Attacker’ in [47]. 5.1.2. Additional Subjects IC Developer Developer of the IC. TOE Developer Developer of part of the TOE source code. 45 | 87 Prepersonalizer Agent in charge of the Prepersonalization. This agent corresponds to the MRTD manufacturer as described in [47]. 5.2. Assets All these data may be sorted out in two different categories: If they are specific to the user, they are User data. If they ensure the correct behaviour of the application, they are TSF Data. 5.2.1. User data Logical MRTD data The logical MRTD data consists of the EF.COM, EF.DG1 to EF.DG16 (with different security needs) and the Document Security Object EF.SOD according to LDS [43]. These data are user data of the TOE. The EF.COM lists the existing elementary files (EF) with the user data. The EF.DG1 to EF.DG13 and EF.DG 16 contain personal data of the MRTD holder. The Chip Authentication Public Key (CAPK) in EF.DG 14 is used by the inspection system for the Chip Authentication. The EF.SOD is used by the inspection system for Passive Authentication of the logical MRTD. The Active Authentication Public Key (AAPK) Info in DG 15 is used by the inspection system for Active Authentication of the chip. The current EAC Security Target is dedicated to the protection of both Active Authentication EF.DG15 (see below) and sensitive biometric EF.DG3&4. The other one (and associated keys) are described and managed in the related BAC Security Target. User Data Description CPLC Data Data uniquely identifying the chip. They are considered as user data as they enable to track the holder Personnal Data of the MRTD holder (EF.DGx, except EF.DG15) Contains identification data of the holder Document Security Object (SOD) in EF.SOD Contain a certificate ensuring the integrity of the file stored within the MRTD and their authenticity. It ensures the data are issued by a genuine country Common data in EF.COM Declare the data the travel document contains. This data is optional and may be absent in the TOE Active Authentication Public Key in EF.DG15 (AAPK) Contains public data enabling to authenticate the chip thanks to the Active Authentication Chip Authentication Public Key in EF.DG14 (CAPK) Contains public data enabling to authenticate the chip thanks to the Chip Authentication Protocol Updatable Data Data other than Personal Data, Biometric Data, EF.COM, EF.SOD, CA_PK, CA_SK, AA_PK, AA_SK, CPLC, TOE_ID, Pre-Perso_K, Perso_K, Session_K, Configuration Data which can be modified in Operational Use phase.

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. Application note: The threats T.Chip_ID and T.Skimming (cf [47]) are averted by the mechanisms described in the BAC PP which cannot withstand an attack with high attack potential thus these are not addressed here. T.Chip_ID addresses the threat of tracing the movement of the MRTD by identifying remotely the MRTD’s chip by establishing or listening to communications through the contactless communication interface. T.Skimming addresses the threat of imitating the inspection system to read the logical MRTD or parts of it via the contactless communication channel of the TOE. Both attacks are conducted by an attacker who cannot read the MRZ or who does not know the physical MRTD in advance. 5.3.1. PP EAC T.Read_Sensitive_Data Adverse action An attacker tries to gain the sensitive biometric reference data through the communication interface of the MRTD's chip. The attack T.Read_Sensitive_Data is similar to the threat T.Skimming (cf. [47]) in respect of the attack path (communication interface) and the motivation (to get data stored on the MRTD's chip) but differs from those in the asset under the attack (sensitive biometric reference data vs. digital MRZ, digitized portrait and other data), the opportunity (i.e. knowing Document Basic Access Keys) and therefore the possible attack methods. Note, that the sensitive biometric reference data are stored only on the MRTD's chip as private sensitive personal data whereas the MRZ data and the portrait are visually readable on the physical MRTD as well. Threat agent Having high attack potential, knowing the Document Basic Access Keys, being in possession of a legitimate MRTD Asset Confidentiality of sensitive logical MRTD (i.e. biometric reference) data T.Forgery Adverse action An attacker alters fraudulently the complete stored logical MRTD or any part of it including its security related data in order to deceive on an inspection system by means of the changed MRTD holder"s identity or biometric reference data. This threat comprises several attack scenarios of MRTD forgery. The attacker may alter the biographical data on the biographical data page of the passport book, in the printed MRZ and in the digital MRZ to claim another identity of the traveler. The attacker may alter the 47 | 87 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.Counterfeit Adverse action An attacker with high attack potential produces an unauthorized copy or reproduction of a genuine MRTD's chip to be used as part of a counterfeit MRTD. This violates the authenticity of the MRTD's chip used for authentication of a traveller by possession of a MRTD. The attacker may generate a new data set or extract completely or partially the data from a genuine MRTD's chip and copy them on another appropriate chip to imitate this genuine MRTD's chip. Threat agent having high attack potential, being in possession of one or more legitimate MRTDs Asset authenticity of logical MRTD data 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 leaking from the TOE during its usage in order to disclose confidential User Data or/and TSF-data stored on the travel document or/and exchanged between the TOE and the terminal connected. The information leakage may be inherent in the normal operation or caused by the attacker. Threat agent having high attack potential. Asset confidentiality of User Data and TSF-data of the travel document. Application note: 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 Differential Electromagnetic Analysis (DEMA) and Differential Power Analysis (DPA). Moreover the attacker may try actively to enforce information leakage by fault injection (e.g. Differential Fault Analysis).. T.Phys-Tamper Adverse action 48 | 87 An attacker may perform physical probing of the travel document in order (i) to disclose the TSF-data, or (ii) to disclose/reconstruct the TOE’s Embedded Software. An attacker may physically modify the travel document in order to alter (I) its security functionality (hardware and software part, as well), (ii) the User Data or the TSF-data stored on the travel document. Threat agent having high attack potential, being in possession of one or more legitimate travel documents. Asset integrity and authenticity of the travel document, availability of the functionality of the travel document, confidentiality of User Data and TSF-data of the travel document. Application note: Physical tampering may be focused directly on the disclosure or manipulation of the user data (e.g. authentication key of the travel document) 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 a direct interaction with the travel document’s internals. Techniques commonly employed in IC failure analysis and IC reverse engineering efforts may be used. Before that, hardware security mechanisms and layout characteristics need to be identified. Determination of software design including treatment of the user data and the TSF data may also be a pre-requisite. The modification may result in the deactivation of a security function, the biometric reference data for the inspection system) or the TSF data (e.g. T.Malfunction Adverse action An attacker may cause a malfunction the travel document’s hardware and Embedded Software by applying environmental stress in order to (i) deactivate or modify security features or functionality of the TOE’ hardware or to (ii) circumvent, deactivate or modify security functions of the TOE’s Embedded Software. This may be achieved e.g. by operating the travel document outside the normal operating conditions, exploiting errors in the travel document’s Embedded Software or misusing administrative functions. To exploit these vulnerabilities an attacker needs information about the functional operation. Threat agent having high attack potential, being in possession of one or more legitimate travel documents, having information about the functional operation. Asset integrity and authenticity of the travel document, availability of the functionality of the travel document, confidentiality of User Data and TSF-data of the travel document. Application note: 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 threat T.PhysTamper) assuming a detailed knowledge about TOE’s internals. 5.3.2. AA T.Counterfeit The definition is in the previous chapter. 5.3.3. Additional Threats T.Forgery_Supplemental_Data “Forgery of supplemental data stored in the TOE” Adverse action An attacker alters fraudulently the data stored in files other than EF.DG1 to EF.DG16, EF.COM and EF document security object. This may lead the extended inspection system (EIS) using these data to be deceived. Threat agent having high attack potential, being in possession of one or more legitimate MRTDs. Asset authenticity of data stored in files other than EF.DG1 to EF.DG16, EF.COM and EF document security object 49 | 87 5.4.

The MRTD is successfully evaluated and certified in accordance with the "Common Criteria Protection Profile Machine Readable Travel Document with "ICAO Application", Basic Access Control" [47] in order to ensure the confidentiality of standard user data and preventing the traceability of the MRTD data. Application note:The organizational security policy P.Personal_Data drawn from the ‘ICAO Doc 9303’ [43] is addressed by the [47] (cf. P.BAC-PP). The confidentiality of the personal data other than EF.DG3 and EF.DG4 is ensured by the BAC mechanism. Note the BAC mechanisms may not resist attacks with high attack potential (cf. [47]). The TOE shall protect the sensitive biometric reference data in EF.DG3 and EF.DG4 against attacks with high attack potential. Due to the different resistance the protection of EF.DG3 and EF.DG4 on one side and the other EF.SOD, EF.COM, EF.DG1, EF.DG2 and EF.DG5 to EF.DG16 are addressed separated protection profiles, which is assumed to result in technically separated evaluations (at least for classes ASE and VAN) and certificates. P.Sensitive_Data The biometric reference data of finger(s) (EF.DG3) and iris image(s) (EF.DG4) are sensitive private personal data of the MRTD holder. The sensitive biometric reference data can be used only by inspection systems which are authorized for this access at the time the MRTD is presented to the inspection system (Extended Inspection Systems). The issuing State or Organization authorizes the Document Verifiers of the receiving States to manage the authorization of inspection systems within the limits defined by the Document Verifier Certificate.

Security Assurance Requirements The security assurance requirement level is EAL5+ augmented with ALC_DVS.2, AVA_VAN.5. 8.2.1. Rationale for augmentation 8.2.1.1. ALC_DVS.2 Sufficiency of security measures 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. Development security is concerned with physical, procedural, personnel and other technical measures that may be used in the development environment to protect the TOE. This assurance component is a higher hierarchical component to EAL5 (only ALC_DVS.1). Due to the nature of the TOE, there is a need for any justification of the sufficiency of these procedures to protect the confidentiality and integrity of the TOE. The component ALC_DVS.2 augmented to EAL5 has no dependencies to other security requirements. 8.2.1.2. AVA_VAN.5 Advanced methodical vulnerability analysis Due to the definition of the TOE, it must be shown to be highly resistant to penetration attacks. This assurance requirement is achieved by the AVA_VAN.5 component. Advanced methodical vulnerability analysis is based on highly detailed technical information. The attacker is assumed to be thoroughly familiar with the specific implementation of the TOE. The attacker is presumed to have a high level of technical sophistication. AVA_VAN.5 has dependencies with ADV_ARC.1 "Security architecture description", ADV_FSP.4 "Complete functional specification", ADV_IMP.1 "Implementation representation of the TSF", ADV_TDS.3 "Basic modular design", AGD_PRE.1 "Preparative procedures" and AGD_OPE.1 "Operational user Guidance" and ATE_DPT.1 "Testing: basic design". All these dependencies are satisfied by EAL5. 79 | 87 9. TOE SUMMARY SPECIFICATION 9.1. TOE Summary Specification Access Control in reading This function controls access to read functions and enforces the security policy for data retrieval. Prior to any data retrieval, it authenticates the actor trying to access the data, and checks the access conditions are fulfilled as well as the life cycle state. It ensures that at any time, the following keys are never readable: - BAC keys - Chip Authentication keys - Active Authentication private key - Personalization Agent keys - MSK and LSK - CVCA keys It controls access to the CPLC data as well: It ensures the CPLC data can be read during the personalization phase It ensures it cannot be readable in free mode at the end of the personalization step. Regarding the file structure: In the operational use: - The terminal can read user data (except DG3 & DG4), the Document Security Object, EF.CVA, EF.COM only after PACE authentication and through a valid secure channel. - When the EAC was successfully performed, the terminal can only read the DG3 & DG4 provided the access rights are sufficient throught a valid secure channel. In the personalization phase: - The Personalization Agent can read all the data stored in the TOE after it is authenticated by the TOE (using its authentication keys). - 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 memory can be accessed at anytime Access Control in writing This function controls access to write functions (in EEPROM) and enforces the security policy for data writing. Prior to any data update, it authenticates the actor, and checks the access conditions are fulfilled as well as the life cycle state. It ensures as well the CPLC data cannot be written anymore once the TOE is personalized. Regarding the file structure: In the operational use: It is not possible to create any files (system or data files). Furthermore, it is not possible to update any system files. However the application data is still accessed internally by the application for its own needs. The root CVCA key files and temporary key files are updated internally by the application according to the authentication mechanism described in [45]. In the personalization phase The Personalization Agent can create and write through a valid secure channel all the data files it needs after it is authenticated by the TOE (using its authentication keys). Active Authentication This security functionality ensures the Active Authentication is performed as described in [45]. (if it is activated by the personnaliser). 80 | 87 Chip Authentication This security functionality ensures the Chip Authentication is performed as described in [45]. (if it is activated by the personnaliser). It could be used as an alternative of Active Authentication to reinforce the Authentication of the Chip. It differs from an EAC not performing the Terminal Authentication. EAC mechanism This security functionality ensures the EAC is correctly performed. In particular: - It handles the certificate verification - The management of the current date (update and control towards the expiration date of the incoming certificate) - The signature verification (in the certificate or in the challenge/response mechanism) It can only be performed once the TOE is personalized with the chip authentication keys & Root CVCA key(s) the Personnalization Agent loaded during the personalization phase. Furthermore, this security functionalities ensure that the authentication is performed as described in [45]. This security functionality ensures the session keys for secure messaging are destroyed at each successful Chip Authentication step. The TOE handles an error counter; after several failures in attempting to strongly authenticate the GIS (the error limit is reached). The TOE also implements countermeasures to protect the TOE; it takes more and more time for the TOE to reply to subsequent wrong GIS authentication attempts. Personalization This security functionality ensures the TOE, when delivered to the Personnalization Agent, demands an authentication prior to any data exchange. This authentication is based on a symmetric Authentication mechanism based on a Triple DES or AES algorithm. This TSF can use a Secure Messaging described in the TSF Secure Messaging. Physical protection This security functionality protects the TOE against physical attacks. Prepersonalization This security functionality ensures the TOE, when delivered to the Prepersonalization Agent, demands an authentication prior to any data exchange. This authentication is based on a symmetric Authentication mechanism based on a Triple DES or AES algorithm. This function is in charge of pre- initializing the product. This TSF can use a Secure Messaging described in the TSF Secure Messaging. Safe state management This security functionalities ensures that the TOE gets back to a secure state when - an integrity error is detected by F.SELFTESTS - a tearing occurs (during a copy of data in EEPROM) This security functionality ensures that such a case occurs, the TOE is either switched in the state "kill card" or becomes mute. Secure Messaging This security functionality ensures the confidentiality, authenticity & integrity of the communication between the TOE and the IFD. After a successful PACE authentication and successful Chip Authentication, a secure channel is established based on Triple DES algorithm, and after a successful Chip Authentication , a secure channel is (re)established based on Symmetric algorithms (Triple DES, AES128, 192 or 256) This security functionality ensures: - No commands were inserted, modified nor deleted within the data flow - The data exchanged remain confidential - The issuer of the incoming commands and the destinatory of the outgoing data is the one that was authenticated (through PACE or EAC) If an error occurs in the secure messaging layer, the session keys are destroyed. This Secure Messaging can be combined with the Active Authentication. This TSF can provide a GP Secure Messaging (SCP02 or SCP03) for the Prepersonalization or Personalization. 81 | 87 Self tests The TOE performs self tests to verify the integrity on the TSF data: - Before the TSF data usage - The integrity of keys and sensitive data is ensured 9.2. Link between the SFR and the TSF The following chapters present the rationales between security objective and security requirements. For ease reading some requirements are merged. - FIA_UAU.4/MP represents the 2 SFRS: FIA_UAU.4/MP_3DES and FIA_UAU.4/MP_AES as the 2 sfrs have the same functionalities, single use authentication mechanisms are used with the same scope. The only difference is the used algorithms. - FIA_UAU.5/MP represents the 2 SFRS: FIA_UAU.5/MP_3DES and FIA_UAU.5/MP_AES as the 2 sfrs have the same functionalities, Multiple use authentication mechanisms are used with the same scope. The only difference is the used algorithms. - FCS_COP.1/MP represents the 7 SFRS: FCS_COP.1/MP_AUTH_3DES, FCS_COP.1/MP_AUTH_AES, FCS_COP.1/MP_ENC_3DES, FCS_COP.1/MP_ENC_AES, FCS_COP.1/MP_MAC_3DES, FCS_COP.1/MP_MAC_AES and FCS_COP.1/MP_SHA. All the SFRs provide equivalent service at personalisation phase: cryptographic authentication of the personalisation. The differences are related to algorithms used for the authentication. 82 | 87 FAU_SAS.1 FCS_CKM.1 FCS_CKM.4 FCS_COP.1/SHA FCS_COP.1/SYM FCS_COP.1/MAC FCS_COP.1/SIG_VER FCS_RND.1 FIA_UID.1 FIA_UAU.1 FIA_UAU.4 FIA_UAU.5 FIA_UAU.6 FIA_API.1 FDP_ACC.1 FDP_ACF.1 FDP_UCT.1 FDP_UIT.1 FMT_SMF.1 FMT_SMR.1 FMT_LIM.1 FMT_LIM.2 FMT_MTD.1/INI_ENA FMT_MTD.1/INI_DIS FMT_MTD.1/CVCA_INI FMT_MTD.1/CVCA_UPD FMT_MTD.1/DATE FMT_MTD.1/KEY_WRITE MT_MTD.1/CAPK FMT_MTD.1/KEY_READ FMT_MTD.3 FPT_EMS.1 FPT_FLS.1 FPT_TST.1 FPT_PHP.3 Access Control in reading X X X X X X X X X X X X Access Control in writing X X X X X X X X Active Authentication X X X X X X X EAC mechanism X X X X X X X X X X X X X X X X X X Personalization X X X X Physical protection X X X X Prepersonalization X X X X X X Safe state management X X X X X X Secure Messaging X X X X X X X X X X X Self tests X X Table 27: Link between SFR from the EAC PP and TSF 83 | 87 FCS_CKM.1/MP FCS_COP.1/MP FDP_ACC.2/MP FDP_ACF.1/MP FDP_ITC.1/MP FDP_UCT.1/MP FDP_UIT.1/MP FIA_AFL.1/MP FIA_UAU.1/MP FIA_UID.1/MP FIA_UAU.4/MP FIA_UAU.5/MP FMT_MTD.1/MP FTP_ITC.1/MP FMT_MTD.1/MP_KEY_READ FMT_MTD.1/MP_KEY_WRITE Access Control in reading X X X X X Access Control in writing X X X X X X X Active Authentication EAC mechanism Personalization X X X Physical protection Prepersonalization X X X X X Safe state management Secure Messaging X X X Self tests Table 28: Link between Additional SFR for MP and TSF 84 | 87 FCS_COP.1/AA FDP_DAU.1/AA FDP_ITC.1/AA FMT_MOF.1/AA FMT_MTD.1/AA_KEY_WRITE FMT_MTD.1/AA_KEY_READ Access Control in reading X Access Control in writing X X X Active Authentication X X X X X X Table 29: Link between SFR for AA and TSF FDP_ACC.1/UPD_FILE FDP_ACF.1/UPD_FILE FMT_MTD.1/UPD_FILE FMT_MTD.1.1/SM_LVL Access Control in reading X X X X Access Control in writing X X X X Active Authentication EAC mechanism X X X Personalization X X X X 85 | 87 Physical protection Prepersonalization X X X X Safe state management Secure Messaging Self tests Table 30: Link between TSF and SFR of the Additions: UPD_FILE and SM_LVL 86 | 87 10.
