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, TÜV Rheinland Nederland 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 TÜV Rheinland Nederland 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 TÜV Rheinland Nederland 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, TÜV Rheinland Nederland 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 The 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 Qualcomm Secure Processor Unit SPU270 (Version: 6.1) in SM8550 SoC (Qualcomm® Snapdragon™ 8 Gen 2) with symmetric and asymmetric crypto support is Qualcomm Technologies, Inc. located in San Diego, USA and they also act as the sponsor of the evaluation. 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 TOE is an integrated Secure Element, composed by the subsystem called Secure Processor Unit (SPU), which is integrated in the SoC within a stacked DDR package on SoC package (package form factor is non-TOE). It is designed as a tamper resistant device providing secure storage and a secure execution environment for processing of sensitive data and for performing cryptographic operations using protected keys stored in its secure storage. Secure Elements can be used for multiple application areas that require a high level of security. The TOE has been evaluated by Riscure B.V. located in Delft, The Netherlands. The evaluation was completed on 20 January 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 scope of the evaluation is defined by the security target [ST], which identifies assumptions made during the evaluation, the intended environment for the Qualcomm Secure Processor Unit SPU270 (Version: 6.1) in SM8550 SoC (Qualcomm® Snapdragon™ 8 Gen 2) with symmetric and asymmetric crypto support, 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 Qualcomm Secure Processor Unit SPU270 (Version: 6.1) in SM8550 SoC (Qualcomm® Snapdragon™ 8 Gen 2) with symmetric and asymmetric crypto support 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 EAL4 augmented (EAL4+) assurance requirements for the evaluated security functionality. This assurance level is augmented with ALC_DVS.2 (Sufficiency of security measures) and AVA_VAN.5 (Advanced methodical vulnerability analysis). 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).

Qualcomm® Secure Processing Unit Enablement for SM8550 Devices – User Guide 80-35348-150, Revision AC SM8550 Security Guidance for Secure Processing Unit Application Developers 80-35348-152, Revision AB SM8550 Secure Processor Unit SDK – API Reference 80-PV579-21, Revision AE Qualcomm® Snapdragon™ Secure Processing Unit (SPU) Application Development User Guide 80-NU430-7, Revision AB SMT Assembly Guidelines SM80-P0982-1, Revision E 2.6 IT Product Testing Testing (depth, coverage, functional tests, independent testing): The evaluators examined the developer’s testing activities documentation and verified that the developer has met their testing responsibilities. 2.6.1 Testing approach and depth The developer performed extensive testing on functional specification, subsystem and SFR-enforcing module level. All parameter choices were addressed at least once. All boundary cases identified were tested explicitly, and additionally the near-boundary conditions were covered probabilistically. The testing was largely automated using industry standard and proprietary test suites. Test scripts were used extensively to verify that the functions return the expected values. 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 executing a small number of test cases designed by the evaluator. All test results were as expected. No deviations were found. 2.6.2 Independent penetration testing The methodical analysis performed was conducted along the following steps: • When evaluating the evidence in the classes ASE, ADV and AGD the evaluator considered whether potential vulnerabilities could already be identified due to the TOE type and/or specified behaviour in such an early stage of the evaluation. • For ADV_IMP a thorough implementation representation review was performed on the TOE focused on the TOE hardware and the IC Dedicated Software. During this attack-oriented analysis, the protection of the TOE is analysed using the knowledge gained from all previous evaluation classes. This resulted in the identification of (additional) potential vulnerabilities. The analysis was performed taking into account the attack methods in [JIL-AM] and applicable attack papers with rating according to [JIL-AAPS]. • All potential vulnerabilities were analysed using the knowledge gained from all evaluation classes and information from the public domain. A judgment was made on how to assure that these potential vulnerabilities are not exploitable. The potential vulnerabilities were addressed by penetration testing, a guidance update or in other ways that are deemed appropriate. The total test effort expended by the evaluators was 26 weeks. During that test campaign, 40% of the total time was spent on Perturbation attacks and 60% on side-channel testing. 2.6.3 Test configuration The TOE hardware and firmware versions for all executed tests were the same as stated in section 2.1 above. The majority of the tests were executed using Test OS as custom test commands were required. The Test OS provided capabilities to disable some countermeasures for the evaluation Page: 10/13 of report number: NSCIB-CC-0569293-CR, dated 14 February 2023 ® TÜV, TUEV and TUV are registered trademarks. Any use or application requires prior approval. purposes. When Test OS was used, the JTAG interface for both the SPU and SoC was unlocked for the test devices for communication with SPU, ease of programming the devices with Test OS as well as to enable faster boot without involving the entire SoC bring up. The evaluator verified that testing on Test OS provides the targeted security functionalities and environment which are representative of the TOE configuration and countermeasures. 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. For composite evaluations, please consult the [ETRfC] for details. 2.7 Reused Evaluation Results There has been extensive reuse of the ALC aspects for the sites involved in the development and production of the TOE, by use of 2 site certificates and 6 Site Technical Audit Reports. 2.8 Evaluated Configuration The TOE is defined uniquely by its name and version number Qualcomm Secure Processor Unit SPU270 (Version: 6.1) in SM8550 SoC (Qualcomm® Snapdragon™ 8 Gen 2) with symmetric and asymmetric crypto support. The TOE can be identified as described in 80-35348-150, Revision AC, as referenced in the [ST]. 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_AMK], [STAR_BA], [STAR_HA], [STAR_SA], [STAR_SD], [STAR_SIN], [STAR_TSMC]3. 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 Qualcomm Secure Processor Unit SPU270 (Version: 6.1) in SM8550 SoC (Qualcomm® Snapdragon™ 8 Gen 2) with symmetric and asymmetric crypto support, to be CC Part 2 extended, CC Part 3 conformant, and to meet the requirements of EAL 4 augmented with ALC_DVS.2 and AVA_VAN.5. 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]. 3 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.

Any use or application requires prior approval. 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: None. 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).
