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.

1 Executive Summary
This Certification Report states the outcome of the Common Criteria security evaluation of the
Qualcomm Secure Processor Unit SPU280 (Version: 7.0) in SM8650 SoC (Qualcomm®
Snapdragon™ 8 Gen 3) with symmetric and asymmetric crypto support. The developer of the
Qualcomm Secure Processor Unit SPU280 (Version: 7.0) in SM8650 SoC (Qualcomm®
Snapdragon™ 8 Gen 3) 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 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 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 was evaluated initially by Riscure B.V. located in Delft, The Netherlands and was certified on
10 November 2023. The re-evaluation of the TOE has also been conducted by Riscure B.V. and was
completed on 16 April 2024 with the approval of the ETR. The re-certification procedure has been
conducted in accordance with the provisions of the Netherlands Scheme for Certification in the Area of
IT Security [NSCIB].
This second issue of the Certification Report is a result of a “recertification with major changes”.
The major changes are:
- Change of security assurance level from EAL4+ to EAL5+
The security evaluation reused the evaluation results of previously performed evaluations. A full, up-
to-date vulnerability analysis has been made.
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 SPU280
(Version: 7.0) in SM8650 SoC (Qualcomm® Snapdragon™ 8 Gen 3) 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 SPU280 (Version: 7.0) in SM8650 SoC (Qualcomm® Snapdragon™ 8 Gen 3)
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 EAL5 augmented (EAL5+) 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).
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.

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 total test effort expended by the evaluators during the baseline evaluation was 29 weeks. During
that test campaign, 7% of the total time was spent on Physical attacks, 29% on Characterisation tests,
24% on Perturbation attacks, and 40% on side-channel testing. No testing was carried out during this
evaluation as it was all reused.

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
purposes. 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
This is a re-certification. Documentary evaluation results from the baseline evaluation 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 multiple site certificates and Site Technical Audit Reports.
2.8 Evaluated Configuration
The TOE is defined uniquely by its name and version number Qualcomm Secure Processor Unit
SPU280 (Version: 7.0) in SM8650 SoC (Qualcomm® Snapdragon™ 8 Gen 3) with symmetric and
asymmetric crypto support.
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]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 SPU280 (Version: 7.0) in SM8650 SoC (Qualcomm® Snapdragon™ 8 Gen 3) with symmetric and
asymmetric crypto support, to be CC Part 2 extended, CC Part 3 conformant, and to meet the
requirements of EAL 5 augmented with ALC_DVS.2 and AVA_VAN.5. This implies that the product
satisfies the security requirements specified in Security Target [ST].
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.

The Security Target claims ’strict’ conformance to the Protection Profile [PP].
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).
