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 TUV 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 TUV Rheinland Nederland B.V. to perform Common Criteria evaluations; a significant requirement for such a license 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, TUV 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, in order 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 and SOG-IS logos on the certificate indicates that this certificate is issued in accordance with the provisions of the CCRA and the SOG-IS agreement and will be recognised by the participating nations. International recognition The CCRA has been signed by the Netherlands in May 2000 and provides mutual recognition of certificates based on the CC. Starting 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. The current list of signatory nations and approved certification schemes can be found on: http://www.commoncriteriaportal.org. European recognition The European SOGIS-Mutual Recognition Agreement (SOGIS-MRA) version 3 effective from April 2010 provides mutual recognition of Common Criteria and ITSEC certificates at a basic evaluation level for all products. A higher recognition level for evaluation levels beyond EAL4 (resp. E3-basic) is provided for products related to specific technical domains. This agreement was initially signed by Finland, France, Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. Italy joined the SOGIS-MRA in December 2010. The current list of signatory nations, approved certification schemes and the list of technical domains for which the higher recognition applies can be found on: http://www.sogisportal.eu.elIDAS-Regulation TUV Rheinland Nederland BV, operating the Netherlands Scheme for Certification in the Area of IT Security (NSCIB), has been notified as a Designated Certification Body from The Netherlands under Article 30(2) and 39(2) of Regulation 910/2014 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 23 July 2014. © TÜV, TUEV and TUV are registered trademarks.

The TOE is comprised of the following main components: Delivery Identifier Version item type Software (binary Sec_trustedcore.img 6.1.0 image) To ensure secure usage a set of guidance documents is provided together with the Huawei iTrustee v5.0. Details can be found in section “Documentation” of this report. For a detailed and precise description of the TOE lifecycle refer to the [ST], chapter 1.5.4. 2.2 Security Policy The TOE is a Trusted OS, which is only the software part of the Trusted Execution Environment (TEE) defined by [TEE PP]. It is for embedded devices implementing GlobalPlatform TEE specifications [SA], TEE Internal API [IAPI] and TEE Client API [CAPI]). However, this TOE does not claim full functional compliance with GlobalPlatform TEE APIs specifications. The TOE is an execution environment isolated from any other execution environment, including the usual Rich Execution Environment (REE), and their applications. The TOE hosts a set of Trusted Applications (TA) and provides them with a comprehensive set of security services including: integrity of execution, secure communication with the Client Applications (CA) running in the REE, trusted storage, key management and cryptographic algorithms, time management and arithmetical API. 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. Detailed information on these security objectives that must be fulfilled by the TOE environment can be found in section 3.2 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 components of the TOE are identified in [ST] Section 1.5.1. The TEE is embedded in the device and runs alongside a standard OS or Rich Execution Environment. The role of the Trusted OS Components, of which the TOE is comprised, is to provide communication facilities with the REE software and the system level functionality required by the Trusted Applications, accessible from the TEE Internal API.

Due to the availability of the test environment in the evaluation premises, and the short execution time of the developer's test cases defined in the test documentation, the evaluator decided to perform a full repetition of all the test cases performed by the developer instead of following a sampling strategy. 2.6.2 Independent Penetration Testing To identify potential vulnerabilities, the evaluator performed the following activities: + When evaluating the evidence in the classes ASE, ADV and AGD the evaluator considered whether potential vulnerabilities can already be identified due to the TOE type and/or specified behaviour in such an early stage of the evaluation. During this attack oriented analysis, the protection of the TOE was analysed using the knowledge gained from all previous evaluation classes. This results in the identification of potential vulnerabilities. * The evaluator performed a search in the public domain in order to identify potential vulnerability. + A preliminary reverse engineering task was performed in order to identify additional potential vulnerabilities and to refine the definition of the prenetratio9n test cases. « All potential vulnerabilities are 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 are addressed by penetration testing, a guidance update or in other ways that are deemed appropriate. 2.6.3 Test Configuration The Huawei iTruste v5.0 was tested in the following configurations: « Huawei iTruste v5.0 (sec_trustedcore.img version 6.1.0) in a kirin 980 SoC (Huawei Mate 20). 2.6.4 Testing 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. 2.7 Re-used evaluation results None. 2.8 Evaluated Configuration The TOE is defined uniquely by its name and version number Huawei iTrustee v5.0. 2.9 Results of the Evaluation The evaluation lab documented their evaluation results in the [ETRP and a ASE Intermediate Report and other evaluator documents. The verdict of each claimed assurance requirement is “Pass”. Based on the above evaluation results the evaluation lab concluded the Huawei iTrustee v5.0, to be CC Part 2 extended, CC Part 3 extended, and to meet the requirements of EAL 2 augmented with © TÜV, TUEV and TUV are registered trademarks.
