Executive Summary This report describes the certification result drawn by the certification body on the results of the EAL5+ evaluation of KCOS e-Passport Version 3.0 S3FT9KS/KT/KF with reference to the Common Criteria for Information Technology Security Evaluation (“CC” hereinafter) [1]. It describes the evaluation result and its soundness and conformity. The Target of Evaluation (TOE) is the composite product which is consisting of the certified contactless integrated circuit chip (IC chip) and embedded software (IC chip operating system(COS), the application of machine readable travel documents (MRTD application) and ISO compliant Driving License (IDL application)). The TOE provides Basic Access Control (BAC), Supplemental Access Control (SAC), Active Authentication (AA), and Extended Access Control (EAC) defined in the ICAO’s Machine Readable Travel Documents, DOC 9303 Part 1 Volume 2, 6th edition, August 2006 [5], the BSI’s Advanced Security Mechanisms Machine Readable Travel Documents – Extended Access Control V1.11, February 2008 [6] and the ICAO MACHINE READABLE TRAVEL DOCUMENTS, TECHNICAL REPORT, Supplemental Access Control for Machine Readable Travel Documents, Version 1.01, November 2010 [12]. Also, the TOE provides Basic Access Protection (BAP), Active Authentication (AA), and Extended Access Protection (EAP) defined in the ISO/IEC 18013 Information technology — Personal identification — ISO-compliant driving license [22]. The TOE KCOS e-Passport Version 3.0 S3FT9KS/KT/KF is composed of the following components:  IC chip S3FT9KF/S3FT9KT/S3FT9KS revision 1 provided by Samsung Electronics, see ANSSI-CC-2013/47, and  Embedded software KCOS e-Passport Version 3.0 provided by KOMSCO. The evaluation of the TOE has been carried out by Telecommunications Technology Association (TTA) and completed on January 13, 2014. This report grounds on the evaluation technical report (ETR) TTA had submitted [7] and the Security Target (ST) [8][9]. The ST is based on the certified Protection Profile (PP) ePassport Protection Profile V2.1, June 10, 2010, KECS-PP-0163a-2009 [10]. All Security Assurance Requirements (SARs) in the ST are based only upon assurance component in CC Part 3, and the TOE satisfies the SARs of Evaluation Assurance Level EAL5 augmented by Certification Report Page 6 ADV_IMP.2, ALC_DVS.2, AVA_VAN.5. Therefore the ST and the resulting TOE is CC Part 3 conformant. The Security Functional Requirements (SFRs) are based upon both functional components in CC Part 2 and a newly defined component in the Extended Component Definition chapter of the ST, and the TOE satisfies the SFRs in the ST. Therefore the ST and the resulting TOE is CC Part 2 extended. [Figure 1] and [Figure 2] shows the operational environment of the TOE in the Personalization and Operational Use phase. The TOE implements security features of both MRTD and IDL application, but the Personalization Agency shall issue one of them in accordance with the intended usage. [Figure 1] Operational environment of the TOE (ePassport) Certification Report Page 7 [Figure 2] Operational environment of the TOE (IDL) Certification Validity: The certificate is not an endorsement of the IT product by the government of Republic of Korea or by any other organization that recognizes or gives effect to this certificate, and no warranty of the IT product by the government of Republic of Korea or by any other organization recognizes or gives effect to the certificate, is either expressed or implied. 2. Identification The TOE is composite product consisting of the following components and related guidance documents. Type Identifier Release Delivery Form HW/SW Samsung S3FT9KF/S3FT9KT/ S3FT9KS 16-bit RISC Microcontroller for Smart Card with optional secure RSA/ECC Library including specific IC Dedicated Software Revision 1 IC Chip Module (Note: The SW is contained in FLASH memory) Secure RSA/ECC Library V3.2 Certification Report Page 8 Type Identifier Release Delivery Form TRNG Library V1 SW KCOS e-Passport Version 3.0 Release 4 DOC Operational User Guidance : EPS- 04-QT-OPE-1.3 V1.3 Softcopy or Hardcopy Preparative Procedures Guidance : EPS-04-QT-PRE-1.3 V1.3 [Table 1] TOE identification TOE is Composite product that should be considered in the Composite Product life cycle. Composite product integrator performs Composite product integration (FLASH code download into the IC chip), preparation and shipping to the personalization for the Composite product (Composite Product Integration). After Composite Product Integration, the ePassport and IDL manufacturer (i.e., inlay and e-Cover, and Card manufacturer) embeds the TOE into the passport booklet and IDL card. Then, the Personalization Agency performs personalization and testing stage where the User Data and TSF Data are loaded into the IC’s memory. The Personalization Agency can only access the TOE using the securely delivered personalization key set. The personalization key set and the Guidance documents are securely delivered (through PGP or directly from the SW developer to the Personalization Agency). Though the certified IC chip which is a component of the TOE provides Contact interfaces and Contactless interfaces (Type A/Type B), the Contact interfaces are not used by the TOE. Thus, the TOE provides Contactless interfaces only. Also, the certified IC chip provides Deterministic Random Number Generator (DRNG), Digital True Random Number Generator (DTRNG), and True Random Number Generator (TRNG), DRNG and DTRNG are not used by the TOE. Thus, TRNG is only used by the TOE. For details on the IC chips, the IC dedicated software and the crypto libraries, see the documentation under ANSSI-CC-2013/47 [11].

Security Policy The ST [8][9] for the TOE claims demonstrable conformance to the ePassport PP [10], and the TOE complies security policies defined in the ePassport PP [10] by security objectives and security requirements based on the ICAO document [5], EAC Certification Report Page 10 specification [6], SAC specification [12], and IDL specification [22]. Thus the TOE provides security features BAC and EAC (EAC-CA, TAC-TA) defined in the ePassport PP [10], SAC defined in the SAC specification [12], BAP and EAP (EAP-CA, EAP-TA) defined in IDL specification [22], and AA. Additionally, the TOE provides security features for Personalization Agent to protect initialization data and application data (during pre-personalization and personalization phase):  Personalization Agent authentication, ensures only authorized entity can access to the TOE during pre-personalization and personalization phase  Secure messaging, ensures transmitted data to be protected from unauthorized disclosure and modification during pre-personalization and personalization phase. Furthermore, the TOE is composite product based on the certified IC chips, the TOE utilizes and therefore provides some security features covered by the IC chip certification such as Security sensors/detectors, Active Shields against physical attacks, Synthesizable glue logic, Dedicated hardware mechanisms against side-channel attacks, Secure DES and AES Symmetric Cryptography support, Secure coprocessor for RSA and ECC Asymmetric Cryptographic Support, and a True Random Number Generator (TRNG), that meet the “standard” level of ANSSI requirements and AIS31. For more details refer to the Security Target Lite for the IC chip [13]. 4. Assumptions and Clarification of Scope The following assumptions describe the security aspects of the operational environment in which the TOE will be used or is intended to be used (for the detailed and precise definition of the assumption refer to the ST [8][9], chapter 3.3):  The Inspection System verifies the Security Object of Document (SOD) after verifying validity of the certificate chain for PA in order to verify for forgery and corruption of the ePassport and IDL identity data recorded in the TOE. For this, the DS certificate and CRL shall be verified periodically. The Inspection System shall securely hold the digital signature generation key that corresponds to the IS certificate and shall provide the TOE with the CVCA link certificate, the DV certificate and the IS certificate in the EAC-TA, and the Alternative Root certificate, L(n)~L(0) certificate in the EAP-TA.  The ePassport Inspection System shall implement security mechanisms of PA, Certification Report Page 11 AA, SAC, BAC and EAC in accordance with the ICAO document [5], EAC specification [6] and SAC specification [12] on the basis of the verifying policy of the ePassport for the ePassport holder. The IDL Inspection System shall implement security mechanisms of PA, AA, BAP and EAP in accordance with the IPD specification [22]. Also, after session termination, the Inspection System shall securely destroy all information, such as the BAC/SAC/BAP session key, the EAC/EAP session key and session information, etc., used in communication with the TOE.  The seed for BAC authentication key takes the sufficient MRZ entropy to ensure the secure BAC authentication key. And the seed for BAP authentication key takes the sufficient entropy to ensure the secure BAP authentication key. Furthermore, some aspects of threats and organisational security policies are not covered by the TOE itself, thus these aspects are addressed by the TOE environment: ePassport/IDL Manufacturing Security, Procedures for ePassport/IDL Holder Confirmation, Interoperability for ePassport/IDL, etc. Details can be found in the ST [8][9], chapter 3.1, 3.2 and 4.3. 5. Architectural Information [Figure 3] shows the physical scope of the TOE. The TOE is the composite product which is consisting of the certified contactless IC chip and the embedded software (i.e., COS, MRTD and IDL application).

TOE Testing The developer’s testing was performed on the final TOE, consisting of the platform, COS, and application. Tests for the TOE are:  Standard and Security Mechanisms Test  Layer 6~7 MRTD Application Protocol & Data Test (Security and Command Test, Logical Data Structure Tests, etc.), which tests MRTD application in accordance with Standard Test Specifications (the ICAO Technical Report RF Protocol and Application Test Standard, BSI TR-03105, BSI TR-03110, etc.), and  Layer 6~7 IDL Application Protocol & Data Test (Security and Command Test, Logical Data Structure Tests, etc.), which tests IDL application in accordance with Standard Test Specifications (ISO/IEC 18013, etc.)  Operational Mode Test : Additional features test which are not defined in the ICAO document [5], EAC specification [6], SAC specification [12], and IDL specification [22] such as pre-personalization, personalization and inspection, Positive and Negative Test for APDUs in each TOE life cycle, life cycle state change, and residual information removal, etc.  Other Test : Layer 3~4 RF Protocol Activation and Transmission Test (anti- Certification Report Page 14 collision test, etc.) The developer tested all the TSF and analyzed testing results in accordance with the assurance component ATE_COV.2. This means that the developer tested all the TSFI defined for each life cycle state of the TOE, and demonstrated that the TSFI behaves as described in the functional specification. The developer tested both subsystems (including their interactions) and modules (including their interfaces), and analyzed testing results in accordance with the assurance component ATE_DPT.3. The developer correctly performed and documented the tests in accordance with the assurance component ATE_FUN.1. The evaluator performed all the developer’s tests listed in this report chapter 7, and conducted independent testing based upon test cases devised by the evaluator. The TOE and test configuration are identical to the developer’s tests. The tests cover preparative procedures in accordance with the guidance. Some tests were performed by design and source code analysis to verify fulfillment of the requirements of the underlying platform to the COS and Application. The implementation of the requirements of the platform’s ETR and guidance as well as of the MRTD and IDL security mechanisms was verified by the evaluators. Also, the evaluator conducted vulnerability analysis and penetration testing based upon test cases devised by the evaluator resulting from the independent, methodical search for potential vulnerabilities. These test cases cover testing APDU commands, bypassability, fault injection attacks, and so on. No exploitable vulnerabilities by attackers possessing high attack potential were found from penetration testing. The evaluator confirmed that all the actual testing results correspond to the expected testing results. The evaluator testing effort, the testing approach, configuration, depth, and results are summarized in the ETR [7]. 8. Evaluated Configuration The TOE is KCOS e-Passport Version 3.0 S3FT9KS/KT/KF. The TOE is composite product consisting of the following components:  IC chips : Samsung S3FT9KF/S3FT9KT/ S3FT9KS 16-bit RISC Microcontroller for Smart Card with optional secure RSA/ECC Library including specific IC Certification Report Page 15 Dedicated Software (ANSSI-CC-2013/47)  Embedded software : KCOS e-Passport Version 3.0 The TOE is identified by the name, version and release number.

Results of the Evaluation The evaluation facility provided the evaluation result in the ETR [7] which references Work Package Reports for each assurance requirement and Observation Reports. The evaluation result was based on the CC [1] and CEM [2], and CCRA supporting documents for the Smartcard and similar device [15], [16], [17], [18], [23], [24]. Also the evaluation facility utilized German scheme’s Evaluation Methodology for CC Assurance Class for EAL5+ and EAL6 [14] under confirmation of the CB. As a result of the evaluation, the verdict PASS is assigned to all assurance components of EAL5 augmented by ADV_IMP.2, ALC_DVS.2 and AVA_VAN.5. 9.1 Security Target Evaluation (ASE) The ST Introduction correctly identifies the ST and the TOE, and describes the TOE in a narrative way at three levels of abstraction (TOE reference, TOE overview and TOE description), and these three descriptions are consistent with each other. Therefore the Certification Report Page 16 verdict PASS is assigned to ASE_INT.1. The Conformance Claim properly describes how the ST and the TOE conform to the CC and how the ST conforms to PPs and packages. Therefore the verdict PASS is assigned to ASE_CCL.1. The Security Problem Definition clearly defines the security problem intended to be addressed by the TOE and its operational environment. Therefore the verdict PASS is assigned to ASE_SPD.1. The Security Objectives adequately and completely address the security problem definition and the division of this problem between the TOE and its operational environment is clearly defined. Therefore the verdict PASS is assigned to ASE_OBJ.2. The Extended Components Definition has been clearly and unambiguously defined, and it is necessary. Therefore the verdict PASS is assigned to ASE_ECD.1. The Security Requirements is defined clearly and unambiguously, and it is internally consistent and the SFRs meet the security objectives of the TOE. Therefore the verdict PASS is assigned to ASE_REQ.2. The TOE Summary Specification addresses all SFRs, and it is consistent with other narrative descriptions of the TOE. Therefore the verdict PASS is assigned to ASE_TSS.1. Also, the evaluator confirmed that the ST of the composite TOE does not contradict the ST of the IC chip in accordance with the CCRA supporting document Composite Product Evaluation [15]. Thus, the ST is sound and internally consistent, and suitable to be used as the basis for the TOE evaluation. The verdict PASS is assigned to the assurance class ASE. 9.2 Life Cycle Support Evaluation (ALC) The developer has used a documented model of the TOE life-cycle. Therefore the verdict PASS is assigned to ALC_LCD.1. The developer has used well-defined development tools (e.g. programming languages or computer-aided design (CAD) systems) that yield consistent and predictable results, and implementation standards have been applied. Therefore the verdict PASS is assigned to ALC_TAT.2. The developer has clearly identified the TOE and its associated configuration items, and the ability to modify these items is properly controlled by automated tools, thus making the CM system less susceptible to human error or negligence. Therefore the Certification Report Page 17 verdict PASS is assigned to ALC_CMC.4. The configuration list includes the TOE, the parts that comprise the TOE, the TOE implementation representation, security flaws, development tools and related information, and the evaluation evidence. These configuration items are controlled in accordance with CM capabilities. Therefore the verdict PASS is assigned to ALC_CMS.5. The developer's security controls on the development environment are adequate to provide the confidentiality and integrity of the TOE design and implementation that is necessary to ensure that secure operation of the TOE is not compromised. Additionally, sufficiency of the measures as applied is intended be justified. Therefore the verdict PASS is assigned to ALC_DVS.2. The delivery documentation describes all procedures used to maintain security of the TOE when distributing the TOE to the user. Therefore the verdict PASS is assigned to ALC_DEL.1. Also, the evaluator confirmed that the correct version of the embedded software is installed onto/into the correct version of the underlying IC chip, and the delivery procedures of IC chip and embedded software developers are compatible with the acceptance procedure of the composite product integrator in accordance with the CCRA supporting document Composite Product Evaluation [15]. Thus, the security procedures that the developer uses during the development and maintenance of the TOE are adequate. These procedures include the life-cycle model used by the developer, the configuration management, the security measures used throughout TOE development, the tools used by the developer throughout the life-cycle of the TOE, the handling of security flaws, and the delivery activity. The verdict PASS is assigned to the assurance class ALC. 9.3 Guidance Documents Evaluation (AGD) The procedures and steps for the secure preparation of the TOE have been documented and result in a secure configuration. Therefore the verdict PASS is assigned to AGD_PRE.1. The operational user guidance describes for each user role the security functionality and interfaces provided by the TSF, provides instructions and guidelines for the secure use of the TOE, addresses secure procedures for all modes of operation, facilitates prevention and detection of insecure TOE states, or it is misleading or unreasonable. Therefore the verdict PASS is assigned to AGD_OPE.1. Certification Report Page 18 Thus, the guidance documents are adequately describing the user can handle the TOE in a secure manner. The guidance documents take into account the various types of users (e.g. those who accept, install, administrate or operate the TOE) whose incorrect actions could adversely affect the security of the TOE or of their own data. The verdict PASS is assigned to the assurance class AGD. 9.4 Development Evaluation (ADV) The TOE design provides a description of the TOE in terms of subsystems sufficient to determine the TSF boundary, and provides a description of the TSF internals in terms of modules. It provides a detailed description of the SFR-enforcing and SFR-supporting modules and enough information about the SFR-non-interfering modules for the evaluator to determine that the SFRs are completely and accurately implemented; as such, the TOE design provides an explanation of the implementation representation. Therefore the verdict PASS is assigned to ADV_TDS.4. The developer has completely described all of the TSFI in a manner such that the evaluator was able to determine whether the TSFI are completely and accurately described, and appears to implement the security functional requirements of the ST. Therefore the verdict PASS is assigned to ADV_FSP.5. The TSF is structured such that it cannot be tampered with or bypassed, and TSFs that provide security domains isolate those domains from each other. Therefore the verdict PASS is assigned to ADV_ARC.1. Also, the evaluator confirmed that the requirements in accordance with the CCRA supporting document ADV_ARC Evaluation [23], [24]. The implementation representation is sufficient to satisfy the functional requirements of the ST and is a correct realisation of the low-level design. Therefore the verdict PASS is assigned to ADV_IMP.2. The TSF internal is well-structured such that the likelihood of flaws is reduced and that maintenance can be more readily performed without the introduction of flaws. Therefore the verdict PASS is assigned to ADV_INT.2. Also, the evaluator confirmed that the requirements on the embedded software, imposed by the IC chip, are fulfilled in the composite product in accordance with the CCRA supporting document Composite Product Evaluation [15]. Thus, the design documentation is adequate to understand how the TSF meets the SFRs and how the implementation of these SFRs cannot be tampered with or bypassed. Design documentation consists of a functional specification (which describes the interfaces of the TSF), a TOE design description (which describes the Certification Report Page 19 architecture of the TSF in terms of how it works in order to perform the functions related to the SFRs being claimed), an implementation description (a source code level description), and TSF internals description (which describes evidence of the structure of the design and implementation of the TSF). In addition, there is a security architecture description (which describes the architectural properties of the TSF to explain how its security enforcement cannot be compromised or bypassed). The verdict PASS is assigned to the assurance class ADV. 9.5 Test Evaluation (ATE) The developer has tested all of the TSFIs, and that the developer's test coverage evidence shows correspondence between the tests identified in the test documentation and the TSFIs described in the functional specification. Therefore the verdict PASS is assigned to ATE_COV.2. The developer has tested all the TSF subsystems and modules against the TOE design and the security architecture description. Therefore the verdict PASS is assigned to ATE_DPT.3. The developer correctly performed and documented the tests in the test documentation. Therefore the verdict PASS is assigned to ATE_FUN.1. By independently testing a subset of the TSF, the evaluator confirmed that the TOE behaves as specified in the design documentation, and had confidence in the developer's test results by performing all of the developer's tests. Therefore the verdict PASS is assigned to ATE_IND.2. Also, the evaluator confirmed that composite product as a whole exhibits the properties necessary to satisfy the functional requirements of its ST in accordance with the CCRA supporting document Composite Product Evaluation [15]. Thus, the TOE behaves as described in the ST and as specified in the evaluation evidence (described in the ADV class). The verdict PASS is assigned to the assurance class ATE. 9.6 Vulnerability Assessment (AVA) By penetrating testing, the evaluator confirmed that there are no exploitable vulnerabilities by attackers possessing High attack potential in the operational environment of the TOE. Therefore the verdict PASS is assigned to AVA_VAN.5. Also, the evaluator confirmed that there is no exploitability of flaws or weakness in the Certification Report Page 20 composite TOE as a whole in the intended environment in accordance with the CCRA supporting document Composite Product Evaluation [15], [16], [17], [18]. Thus, potential vulnerabilities identified, during the evaluation of the development and anticipated operation of the TOE or by other methods (e.g. by flaw hypotheses or quantitative or statistical analysis of the security behaviour of the underlying security mechanisms), don’t allow attackers possessing High attack potential to violate the SFRs. The verdict PASS is assigned to the assurance class AVA. 9.7 Evaluation Result Summary Assurance Class Assurance Component Evaluator Action Elements Verdict Evaluator Action Elements Assurance Component Assurance Class ASE ASE_INT.1 ASE_INT.1.1E PASS PASS PASS ASE_INT.1.2E PASS ASE_CCL.1 ASE_CCL.1.1E PASS PASS ASE_SPD.1 ASE_SPD.1.1E PASS PASS ASE_OBJ.2 ASE_OBJ.2.1E PASS PASS ASE_ECD.1 ASE_ECD.1.1E PASS PASS ASE_ECD.1.2E PASS ASE_REQ.2 ASE_REQ.2.1E PASS PASS ASE_TSS.1 ASE_TSS.1.1E PASS PASS ASE_TSS.1.2E PASS ALC ALC_LCD.1 ALC_LCD.1.1E PASS PASS PASS ALC_TAT.2 ALC_TAT.2.1E PASS PASS ALC_CMS.5 ALC_CMS.5.1E PASS PASS ALC_CMC.4 ALC_CMC.4.1E PASS PASS ALC_DVS.2 ALC_DVS.2.1E PASS PASS ALC_DVS.2.2E PASS ALC_DEL.1 ALC_DEL.1.1E PASS PASS AGD AGD_PRE.1 AGD_PRE.1.1E PASS PASS PASS AGD_PRE.1.2E PASS PASS AGD_OPE.1 AGD_OPE.1.1E PASS PASS Certification Report Page 21 Assurance Class Assurance Component Evaluator Action Elements Verdict Evaluator Action Elements Assurance Component Assurance Class ADV ADV_TDS.4 ADV_TDS.4.1E PASS PASS PASS ADV_TDS.4.2E PASS PASS ADV_FSP.5 ADV_FSP.5.1E PASS PASS ADV_FSP.5.2E PASS ADV_ARC.1 ADV_ARC.1.1E PASS PASS ADV_IMP.2 ADV_IMP.2.1E PASS PASS ADV_INT.2 ADV_INT.2.1E PASS PASS ADV_INT.2.2E PASS ATE ATE_COV.2 ATE_COV.2.1E PASS PASS PASS ATE_DPT.3 ATE_DPT.3.1E PASS PASS ATE_FUN.1 ATE_FUN.1.1E PASS PASS ATE_IND.2 ATE_IND.2.1E PASS PASS ATE_IND.2.2E PASS ATE_IND.2.3E PASS AVA AVA_VAN.5 AVA_VAN.5.1E PASS PASS PASS AVA_VAN.5.2E PASS AVA_VAN.5.3E PASS AVA_VAN.5.4E PASS [Table 4] Evaluation Result Summary 10. Recommendations The TOE security functionality can be ensured only in the evaluated TOE operational environment with the evaluated TOE configuration, thus the TOE shall be operated by complying with the followings:  The Guidance documents listed in this report chapter 6, contain necessary information about the usage of the TOE and all security recommendations have to be considered. All aspects of Assumptions, Threats and Organizational Security Policies in the ST [8][9] not covered by the TOE itself need to be Certification Report Page 22 fulfilled by the operational environment of the TOE.  When secure messaging is not applied during personalization phase in accordance with the policy of the Personalization Agent, it is strongly recommended that the physical, procedural and personal security measures are in place in order to ensure confidentiality and integrity of the transmitted data during personalization phase. For the MRTD application,  The TOE can be configured in a way that it deactivates EAC by excluding DG3 and DG4 from the ePassport. Though it depends on the policy of the Personalization Agents whether they activate EAC or not, it is strongly recommended that the Personalization Agent activates EAC by including DG3 and DG4 because the evaluated TOE configuration includes EAC.  It has to be ensured that MRZ data which are used to derive BAC authentication keys provides sufficient entropy to withstand related attacks.  The TOE supports both SAC and BAC to ensure global interoperability. Thus, the Inspection System SHOULD use SAC instead of BAC. For the IDL application,  Though it depends on the policy of the Personalization Agents whether they activate EAP or not, it is strongly recommended that the Personalization Agent activates both BAP and EAP because the evaluated TOE configuration includes all of them.  Access to biometric data of the IDL optional data, EAP authority is required. Access to other data of the IDL optional data, BAP or EAP authority is required according to the policy of the Personalization Agent (IS can be confirmed the authority of DG, through the reading EF.COM).  It has to be ensured that data which are used to derive BAP authentication keys provides sufficient entropy to withstand related attacks. 11.
