Foreword The Netherlands Scheme for Certification in the Area of IT Security (NSCIB) provides a third-party evaluation and certification service for determining the trustworthiness of Information Technology (IT) security products. Under this NSCIB, TrustCB B.V. has the task of issuing certificates for IT security products, as well as for protection profiles and sites. Part of the procedure is the technical examination (evaluation) of the product, protection profile or site according to the Common Criteria assessment guidelines published by the NSCIB. Evaluations are performed by an IT Security Evaluation Facility (ITSEF) under the oversight of the NSCIB Certification Body, which is operated by TrustCB B.V. in cooperation with the Ministry of the Interior and Kingdom Relations. An ITSEF in the Netherlands is a commercial facility that has been licensed by TrustCB B.V. to perform Common Criteria evaluations; a significant requirement for such a licence is accreditation to the requirements of ISO Standard 17025 “General requirements for the accreditation of calibration and testing laboratories”. By awarding a Common Criteria certificate, TrustCB B.V. asserts that the product or site complies with the security requirements specified in the associated (site) security target, or that the protection profile (PP) complies with the requirements for PP evaluation specified in the Common Criteria for Information Security Evaluation. A (site) security target is a requirements specification document that defines the scope of the evaluation activities. The consumer should review the (site) security target or protection profile, in addition to this certification report, to gain an understanding of any assumptions made during the evaluation, the IT product's intended environment, its security requirements, and the level of confidence (i.e., the evaluation assurance level) that the product or site satisfies the security requirements stated in the (site) security target.

Recognition of the Certificate Presence of the Common Criteria Recognition Arrangement (CCRA) and the SOG-IS logos on the certificate indicates that this certificate is issued in accordance with the provisions of the CCRA and the SOG-IS Mutual Recognition Agreement (SOG-IS MRA) and will be recognised by the participating nations. International recognition The CCRA was signed by the Netherlands in May 2000 and provides mutual recognition of certificates based on the Common Criteria (CC). Since September 2014 the CCRA has been updated to provide mutual recognition of certificates based on cPPs (exact use) or STs with evaluation assurance components up to and including EAL2+ALC_FLR. For details of the current list of signatory nations and approved certification schemes, see http://www.commoncriteriaportal.org. European recognition The SOG-IS MRA Version 3, effective since April 2010, provides mutual recognition in Europe of Common Criteria and ITSEC certificates at a basic evaluation level for all products. A higher recognition level for evaluation levels beyond EAL4 (respectively E3-basic) is provided for products related to specific technical domains. This agreement was signed initially by Finland, France, Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. Italy joined the SOG-IS MRA in December 2010. For details of the current list of signatory nations, approved certification schemes and the list of technical domains for which the higher recognition applies, see https://www.sogis.eu.

The developer of the SN200 Series - Secure Element with Crypto Library SN200_SE B1.1 C04 is NXP Semiconductors Germany GmbH located in Hamburg, Germany and they also act as the sponsor of the evaluation and certification. A Certification Report is intended to assist prospective consumers when judging the suitability of the IT security properties of the product for their particular requirements. The SN200x Single Chip Secure Element and NFC controller Series combines on a single die an Embedded Secure Element, an NFC Controller, and the Power Management Unit. The three subsystems are called “SN200_SE”, “SN200_PMU”, and “SN200_NFC”. The TOE is the SN200_SE. The NFC Controller and the PMU are not part of the TOE. The TOE is the SN200_SE B1.1 in one configuration SN200_SE B1.1 C04. The TOE will be provided with Crypto Library and Services Software as part of the IC Dedicated Software. The TOE is a Security Integrated Circuit Platform for various operating systems and applications with high security requirements. The TOE was previously evaluated by Riscure B.V. located in Delft, The Netherlands and was certified under the accreditation of TÜV Rheinland Nederland on 05 October 2021 (CC-21-217812). The current evaluation of the TOE has also been conducted by Riscure B.V. and was completed on 16 March 2023 with the approval of the ETR. The certification procedure has been conducted in accordance with the provisions of the Netherlands Scheme for Certification in the Area of IT Security [NSCIB]. The major changes from previous evaluations are: (i) Separation of one site into two, (ii) merge of two sites, (iii) relocation of one site. These changes are covered by site certificates and included by use of related STARs. (iv) Adding a second wafer fab (GF1 Dresden), (v) security guidance update (Crypto Library), and (vi) adding two further sites involved in engineering activities. The certification took into account that the security evaluation reused the evaluation results of previously performed evaluations. A full, up-to-date vulnerability analysis has been made, as well as renewed testing. The scope of the evaluation is defined by the security target [ST], which identifies assumptions made during the evaluation, the intended environment for the SN200 Series - Secure Element with Crypto Library SN200_SE B1.1 C04, the security requirements, and the level of confidence (evaluation assurance level) at which the product is intended to satisfy the security requirements. Consumers of the SN200 Series - Secure Element with Crypto Library SN200_SE B1.1 C04 are advised to verify that their own environment is consistent with the security target, and to give due consideration to the comments, observations and recommendations in this certification report. The results documented in the evaluation technical report [ETR] 1 for this product provide sufficient evidence that the TOE meets the EAL6 augmented (EAL6+) assurance requirements for the evaluated security functionality. This assurance level is augmented with ALC_FLR.1 (Flaw Remediation) and ASE_TSS.2 (TOE Summary Specification with architectural design summary). The evaluation was conducted using the Common Methodology for Information Technology Security Evaluation, Version 3.1 Revision 5 [CEM] for conformance to the Common Criteria for Information Technology Security Evaluation, Version 3.1 Revision 5 [CC] (Parts I, II and III). TrustCB B.V., as the NSCIB Certification Body, declares that the evaluation meets all the conditions for international recognition of Common Criteria Certificates and that the product will be listed on the NSCIB Certified Products list. Note that the certification results apply only to the specific version of the product as evaluated. 1 The Evaluation Technical Report contains information proprietary to the developer and/or the evaluator, and is not available for public review.

The TOE is comprised of the following main components: Delivery item type Identifier Version Hardware SN200_SE (Base layer and fixed metal masks) B1.1 Software (IC Dedicated Support Software) Factory OS 7.0.6 Boot OS 7.0.5 Flash Driver Software 7.0.1 Table 1 Components common for all SN200_SE B1.1 Delivery item type Identifier Version Configuration Data Factory Page 19554 System Page Common 20103 BootOS Patch 7.0.5 PL3 v9 Security Software Services Software 4.13.3.0 Crypto Library 1.0.0 Table 2 Components of SN200_SE B1.1 specific for C04 To ensure secure usage a set of guidance documents is provided, together with the SN200 Series - Secure Element with Crypto Library SN200_SE B1.1 C04. For details, see section 2.5 “Documentation” of this report. For a detailed and precise description of the TOE lifecycle, see the [ST], Chapter 1.3.3. 2.2 Security Policy The security functionality of SN200_SE is designed to act as an integral part of a security system composed of SN200_SE and Security IC Embedded Software to strengthen it as a whole. Several security mechanisms of SN200_SE are completely implemented in and controlled by SN200_SE. Other security mechanisms must be treated by Security IC Embedded Software. All security functionality is targeted for use in a potential insecure environment, in which SN200_SE maintains • correct operation of the security functionality, • integrity and confidentiality of data and code stored to its memories and processed in the device, • controlled access to memories and hardware components supporting separation of different applications. This is ensured by the construction of SN200_SE and its security functionality. SN200_SE basically provides: • hardware to perform computations on multiprecision integers, which are suitable for public-key cryptography, • hardware to calculate the Data Encryption Standard with up to three keys, • hardware to calculate the Advanced Encryption Standard (AES) with different key lengths, • hardware to support Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB) and Counter (CTR) modes of operation for symmetric-key cryptographic block ciphers, Page: 7/14 of report number: NSCIB-CC-2200037-01-CR, dated 16 March 2023 ® TrustCB is a registered trademark. Any use or application requires prior approval. • hardware to support Galois/Counter Mode (GCM) of operation and Galois Message Authentication Code (GMAC) for symmetric-key cryptographic block ciphers, • hardware to calculate Cyclic Redundancy Checks (CRC), • hardware to serve with True Random Numbers, • hardware and service software to control access to memories and hardware components. In addition, SN200_SE embeds sensors, which ensure proper operating conditions of the device. Integrity protection of data and code involves error correction and error detection codes, light sensing and other security functionality. Encryption and masking mechanisms are implemented to preserve confidentiality of data and code. The IC hardware is shielded against physical attacks. The Crypto Library consists of several binary packages that are pre-loaded to the Flash memory of the TOE for usage by the Security IC Embedded Software. The Crypto Library provides: • AES • Triple-DES (3DES) • RSA • RSA key generation • RSA public key computation • ECDSA (ECC over GF(p)) signature generation and verification • ECDSA (ECC over GF(p)) key generation • ECDH (ECC Diffie-Hellmann) key exchange • MontDH (Diffie Hellman key exchange on Montgomery Curves over GF(p)) key generation • MontDH (Diffie Hellman key exchange on Montgomery Curves over GF(p)) key exchange • EdDSA (Edwards-curve Digital Signature Algorithm) signature generation and verification • EdDSA (Edwards-curve Digital Signature Algorithm) key generation • ECDAA related functions • Full point addition (ECC over GF(p)) • Standard security level SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3/224, SHA-3/256, SHA-3/384, SHA-3/512 algorithms • High security level SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3/224, SHA-3/256, SHA-3/384, SHA-3/512 algorithms • HMAC algorithms • eUICC authentication functions (MILENAGE, TUAK and CAVE) In addition, the Crypto Library implements a software (pseudo) random number generator which is initialized (seeded) by the hardware random number generator of the TOE. The Crypto Library also provides a secure copy routine, a secure memory compare routine, cyclic redundancy check (CRC) routines, and includes internal security measures for residual information protection. 2.3 Assumptions and Clarification of Scope 2.3.1 Assumptions The assumptions defined in the Security Target are not covered by the TOE itself. These aspects lead to specific Security Objectives to be fulfilled by the TOE-Environment. For detailed information on the security objectives that must be fulfilled by the TOE environment, see section 4.2 and 4.3 of the [ST]. 2.3.2 Clarification of scope The evaluation did not reveal any threats to the TOE that are not countered by the evaluated security functions of the product. 2.4 Architectural Information The SN200x Single Chip Secure Element and NFC controller Series combines on a single die an Embedded Secure Element, an NFC Controller, and the Power Management Unit. The three subsystems are called “SN200_SE”, “SN200_PMU”, and “SN200_NFC”. The TOE is the SN200_SE. The NFC Controller and the PMU are not part of the TOE. Page: 8/14 of report number: NSCIB-CC-2200037-01-CR, dated 16 March 2023 ® TrustCB is a registered trademark. Any use or application requires prior approval. The TOE is the SN200_SE B1.1 in one SN200_SE B1.1 C04. The TOE will be provided with Crypto Library and Services Software as part of the IC Dedicated Software. A block diagram is given in Figure 1 below. IC Hardware The SN200x Single Chip Secure Element and NFC controller Series combines on a single die an Embedded Secure Element, an NFC Controller, and the Power Management Unit. The three subsystems are called “SN200_SE”, “SN200_PMU”, and “SN200_NFC”. The TOE is the SN200_SE. The NFC Controller and the PMU are not part of the TOE. The TOE is the SN200_SE B1.1 in one SN200_SE B1.1 C04. The TOE will be provided with Crypto Library and Services Software as part of the IC Dedicated Software. The hardware part of the SN200_SE incorporates a high frequency clocked ARM SC300 processor, a Public-Key Cryptography (PKC) coprocessor and a Direct Memory Access (DMA) controller, which are all connected over a Memory Management Unit (MMU) to a bus system. This bus system gives access to memories, hardware peripherals and communication interfaces. The ARM SC300 processor is a security enhanced variant of the ARM Cortex M3. It includes the SC300 core and the Nested Vector Interrupt Controller (NVIC). The core implements the ARMv7-M architecture, which supports a subset of the Thumb instruction set. The PKC coprocessor provides large integer arithmetic operations, which can be used by Security IC Embedded Software for asymmetric-key cryptography. Hardware peripherals include coprocessors for symmetric-key cryptography and for calculation of error-detecting codes, and also a random number generator. The DMA controller manages data transfers over communication interfaces like ISO/IEC 7816 compliant interface, Serial Peripheral Interface (SPI), I2C interface and the Secure Mailbox Interface. On-chip memories are Flash memory, ROM and RAMs. The Flash memory can be used to store data and code of Security IC Embedded Software. It is designed for reliable non-volatile storage. SN200_SE is offered with the NXP Trust Provisioning Service, which involves secure reception, generation, treatment and insertion of customer data and code at NXP. The documentation of SN200_SE includes a product data sheet, several product data sheet addenda, a user guidance and operation manual, and service documentation. This documentation describes secure configuration and secure use of SN200_SE as well as the services provided with it. Also, the IC Dedicated Support Software is considered part of the IC Hardware, as it is stored to the ROM of the TOE. It consists of the Factory OS, the Boot OS and the Flash Driver Software. Security Software The IC Dedicated Software provides Security Software that can be used by the Security IC Embedded Software. The Security Software is composed of Services Software and Crypto Library. The Services Software consists of Flash Services Software, Services Framework Software and the part of the Services HAL (Hardware Abstraction Layer) that is not stored to ROM. The Flash Services Software manages technical demands of the Flash memory and serves the Security IC Embedded Software with an interface for Flash erase and/or programming. The Services Framework Software represents a collection of different abstractions and utility functions that provide a runtime environment to the individual Services. The Services HAL provides an interface for the Services Software to the hardware that controls the Flash memory. The Services Software is considered part of the Service Code and is stored in the Flash memory of the TOE.

The testing was largely automated using industry standard and proprietary test suites. Test scripts were extensively used to verify that the functions return the expected values. The underlying hardware and crypto-library test results are extendable to composite evaluations, because the underlying platform is operated according to its guidance and the composite evaluation requirements are met. For the testing performed by the evaluators, the developer provided samples and a test environment. The evaluators reproduced a selection of the developer tests, as well as a small number of test cases Page: 11/14 of report number: NSCIB-CC-2200037-01-CR, dated 16 March 2023 ® TrustCB is a registered trademark. Any use or application requires prior approval. designed by the evaluator. For the evaluator defined tests the developer delivered samples (and support in writing scripts). However, Riscure’s test environment was used for these ATE_IND tests. 2.6.2 Independent penetration testing The evaluator independent penetration tests were conducted according to the following testing approach: • During evaluation of the ADV, ATE and ALC classes the evaluators hypothesized possible vulnerabilities. This resulted in a shortlist of possible vulnerabilities to be further analysed in AVA using the design knowledge gained in particular from the source code analysis in IMP. This resulted in a shortlist of potential vulnerabilities to be tested. • Next the evaluators analysed the TOE design and implementation for resistance against the JIL attacks. This resulted in further potential vulnerabilities to be tested. • The evaluators made an analysis of the TOE in its intended environment to check whether the developer vulnerability analysis in ARC has assessed all information. • The evaluators concluded that a number of areas could be potentially vulnerable for attackers possessing a high attack potential. Consequently, practical penetration testing was performed for absolute assurance. Considering the vulnerability analysis results of the previous evaluation, derived tests and penetration test results the evaluator determined what additional penetration tests were necessary and which tests from the previous evaluation needed to be repeated. The total test effort expended by the evaluator was 11 weeks. During that test campaign, 47% of the total time was spent on Perturbation attacks, 53% on side-channel testing, and 0% on logical tests. These numbers cover the effort just for this evaluation. Details of the previous certifications can be found under TÜV Rheinland (CC-21-217812). 2.6.3 Test configuration Penetration testing was performed on the TOE and also on slightly different configurations of the TOE SN200_SE B1.1 C04. The differences between these configurations and the TOE have been analysed. They have no impact on the test results, hence the test results apply to the TOE. 2.6.4 Test results The testing activities, including configurations, procedures, test cases, expected results and observed results are summarised in the [ETR], with references to the documents containing the full details. The developer’s tests and the independent functional tests produced the expected results, giving assurance that the TOE behaves as specified in its [ST] and functional specification. No exploitable vulnerabilities were found with the independent penetration tests. The algorithmic security level of cryptographic functionality has not been rated in this certification process, but the current consensus on the algorithmic security level in the open domain, i.e., from the current best cryptanalytic attacks published, has been taken into account. Not all key sizes specified in the [ST] have sufficient cryptographic strength for satisfying the AVA_VAN.5 “high attack potential”. The TOE supports a wider range of key sizes (see [ST]), including those with sufficient algorithmic security level to exceed 100 bits as required for high attack potential (AVA_VAN.5). The strength of the implementation of the cryptographic functionality has been assessed in the evaluation, as part of the AVA_VAN activities. So, no exploitable vulnerabilities were found with the independent penetration tests. For composite evaluations, please consult the [ETRfC] for details. 2.7 Reused Evaluation Results Documentary evaluation results of the earlier version of the TOE have been reused, but vulnerability analysis and penetration testing has been renewed. There has been extensive reuse of the ALC aspects for the sites involved in the development and production of the TOE, by use of 27 site certificates and 27 Site Technical Audit Reports. Page: 12/14 of report number: NSCIB-CC-2200037-01-CR, dated 16 March 2023 ® TrustCB is a registered trademark. Any use or application requires prior approval. No sites have been visited as part of this evaluation. 2.8 Evaluated Configuration The TOE is defined uniquely by its name and version number SN200 Series - Secure Element with Crypto Library SN200_SE B1.1 C04. The user can identify the certified configuration by reading the TypeID bytes. The details are described in the guidance documentation. 2.9 Evaluation Results The evaluation lab documented their evaluation results in the [ETR], which references an ASE Intermediate Report and other evaluator documents, and Site Technical Audit Reports for the sites [STAR] 2. To support composite evaluations according to [COMP] a derived document [ETRfC] was provided and approved. This document provides details of the TOE evaluation that must be considered when this TOE is used as platform in a composite evaluation. The verdict of each claimed assurance requirement is “Pass”. Based on the above evaluation results the evaluation lab concluded the SN200 Series - Secure Element with Crypto Library SN200_SE B1.1 C04, to be CC Part 2 extended, CC Part 3 conformant, and to meet the requirements of EAL 6 augmented with ALC_FLR.1 (Flaw Remediation) and ASE_TSS.2 (TOE Summary Specification with architectural design summary).This implies that the product satisfies the security requirements specified in Security Target [ST]. The Security Target claims ’strict’ conformance to the Protection Profile [PP_0084]. 2.10 Comments/Recommendations The user guidance as outlined in section 2.5 “Documentation” contains necessary information about the usage of the TOE. Certain aspects of the TOE’s security functionality, in particular the countermeasures against attacks, depend on accurate conformance to the user guidance of both the software and the hardware part of the TOE. There are no particular obligations or recommendations for the user apart from following the user guidance. Please note that the documents contain relevant details concerning the resistance against certain attacks. In addition, all aspects of assumptions, threats and policies as outlined in the Security Target not covered by the TOE itself must be fulfilled by the operational environment of the TOE. The customer or user of the product shall consider the results of the certification within his system risk management process. For the evolution of attack methods and techniques to be covered, the customer should define the period of time until a re-assessment for the TOE is required and thus requested from the sponsor of the certificate. The strength of the cryptographic algorithms and protocols was not rated in the course of this evaluation. This specifically applies to the following proprietary or non-standard algorithms, protocols and implementations: KoreanSeed, OSCCA SM2, OSCCA SM3 and OSCCA SM4, and FeliCa which are out of scope as there are no security claims. Not all key sizes specified in the [ST] have sufficient cryptographic strength to satisfy the AVA_VAN.5 “high attack potential”. To be protected against attackers with a "high attack potential", appropriate cryptographic algorithms with sufficiently large cryptographic key sizes shall be used (references can be found in national and international documents and standards). 2 The Site Technical Audit Report contains information necessary to an evaluation lab and certification body for the reuse of the site audit report in a TOE evaluation.
