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 NXP
SN330 A0 Series - Secure Element SN330_SE A0.1.000 J10. The developer of the NXP SN330 A0
Series - Secure Element SN330_SE A0.1.000 J10 is NXP Semiconductors 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 TOE is a Security Integrated Circuit Platform for operating systems and applications with high
security requirements. The SN330 A0 Single Chip Secured (NFC) Controller Series 1 combines on a
single die an Embedded Secure Element and a NFC Controller. The two subsystems are called
"SN330_SE" and "SN330_NFC". The NFC Controller is not part of the TOE. The Embedded Secure
Element SN330_SE is based on a Flash-based secure microcontroller platform. A high frequency
clocked ARM Cortex M33 core along with state of the art cryptographic hardware coprocessors brings
secured applications to a new level in performances and security. The TOE is integral part of the
SN330 A0 IC.
The TOE has been evaluated by TÜV Informationstechnik GmbH located in Essen, Germany. The
evaluation was completed on 12 December 2024 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 NXP SN330 A0 Series - Secure Element
SN330_SE A0.1.000 J10, 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 NXP SN330 A0 Series - Secure Element SN330_SE A0.1.000 J10 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 (Basic 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.

2 Certification Results
2.1 Identification of Target of Evaluation
The Target of Evaluation (TOE) for this evaluation is the NXP SN330 A0 Series - Secure Element
SN330_SE A0.1.000 J10 from NXP Semiconductors GmbH located in Hamburg, Germany.
The TOE is comprised of the following main components:
Delivery
item type
Identifier Version
Hardware NXP SN330 A0 Series - Secure Element SN330_SE A0.1.000 J10
Software
Test Software / FactoryOS 6.0.5
Boot Software / Boot OS 6.0.6
Flash Driver Software 6.0.3
To ensure secure usage a set of guidance documents is provided, together with the NXP SN330 A0
Series - Secure Element SN330_SE A0.1.000 J10. 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 the TOE is designed to act as an integral part of a security system
composed of hardware and Security IC Embedded Software to strengthen it as a whole. Several
security mechanisms of the TOE are completely implemented in and controlled by the SN330 A0
Secure Element. 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 the TOE
maintains
• correct operation of the security functionality
• integrity and confidentiality of data and code stored to its memories and processed in the
device
This is ensured by the construction of TOE and its security functionality.
The TOE provides a hardware platform for an implementation of a smartcard
application with:
• 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
• hardware to support Galois/Counter Mode (GCM) of operation for symmetric-key
cryptographic block ciphers
• hardware to calculate Cyclic Redundancy Checks (CRC)
• hardware to serve with True Random Numbers
In addition, the hardware embeds sensors, which ensure proper operating conditions of the device.
Integrity protection of data and code involves error correction and error detection codes, EMFI
detector, light sensing and other security functionality. Memory encryption and masking mechanisms
are implemented to preserve confidentiality of data. The IC hardware is shielded against physical
attacks. And the lockstep (redundant) CPU ensures protection against faults in the CPU.

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 4.2.1 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.
The secure operation of cryptographic functionality in section 2.2 requires a Cryptographic Library
which is not part of this TOE. Therefore, Security Services and Security Features using this
cryptographic functionality need to be evaluated in the composite product together with Cryptographic
Library as part of the Security IC Embedded Software. As a consequence, for the cryptographic
functionality the scope of this evaluation is confined to protection against physical manipulation.
2.4 Architectural Information
The TOE architecture can be depicted as follows:
The TOE incorporates an high frequency clocked ARM Cortex M33 processor augmented with its
dedicated coprocessor (SYM-lite), a secure copy machine (SMA), and a Public-Key Cryptography
(PKC) coprocessor, which are all connected to a bus system. This bus system gives access to
memories, hardware peripherals and communication interfaces. 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. 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.

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 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 a small number of test cases
designed by the evaluator.
2.6.2 Independent penetration testing
The independent vulnerability analysis was conducted along the following steps:
• Systematic search for potential vulnerabilities and known attacks in public domain sources,
use of a list of vulnerabilities, and from a methodical analysis of the evaluation documents.
• Analysis why these vulnerabilities are unexploitable in the intended environment of the TOE.
• If the rationale is suspect in the opinion of the evaluator penetration tests are devised.
• Even if the rational is convincing in the opinion of the evaluator, penetration tests are devised
for some vulnerabilities, especially to support the argument of non- practicability of exploiting
time in case of SPA, DPA and FI attacks.
The total test effort expended by the evaluators was 61 days. During that test campaign, 85% of the
total time was spent on Perturbation attacks, and 15% on side-channel testing.
2.6.3 Test configuration
The following configuration was used for testing:
• NXP SN330 A0 Series - Secure Element SN330_SE A0.1.000 J10
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.
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 25 site certificates.
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 NXP SN330 A0 Series - Secure
Element SN330_SE A0.1.000 J10.
2.9 Evaluation Results
The evaluation lab documented their evaluation results in the [ETR], which references an ASE
Intermediate Report and other evaluator documents. 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 NXP SN330 A0 Series -
Secure Element SN330_SE A0.1.000 J10, to be CC Part 2 extended, CC Part 3 conformant, and to
meet the requirements of EAL 6 augmented with ALC_FLR.1 and ASE_TSS.2. 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.
