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 ZTE
gNodeB Core Software V5.65.20.10F12. The developer of the ZTE gNodeB Core Software
V5.65.20.10F12 is ZTE Corporation located in Shenzhen, P.R.C. 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 the core software of ZTE 5G gNodeB base station, which provides the communication with
the terminal, the 5GC/Backhaul network, the management interfaces and other security related
functionality.
The TOE is mainly used to provide secure access for terminals and secure data backhaul. In addition,
user access control and security log recording are also important parts of the TOE.
The TOE has been evaluated by SGS Brightsight B.V. located in Delft, The Netherlands. The
evaluation was completed on 22 April 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 ZTE gNodeB Core Software V5.65.20.10F12,
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 ZTE gNodeB Core Software
V5.65.20.10F12 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_FLR.2 (Flaw Reporting
Procedures).
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 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.
The evaluator created additional test cases test to confirm verification of the version of the TOE / to
supplement coverage of SFRs and/or TSFI / to further exercise the behaviour of critical functionality.

2.6.2 Independent penetration testing
The focused vulnerability analysis was conducted along the following steps:
• When evaluating the evidence in the classes ASE, ADV and AGD the evaluator considers
whether potential vulnerabilities can 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 is performed on the TOE.
During this attack oriented analysis, the protection of the TOE is analysed using the
knowledge gained from all previous evaluation classes. This results in the identification of
(additional) potential vulnerabilities.
• Applicablepotentialvulnerabilitiesareanalysedusingtheknowledgegainedfromallevaluationclass
es 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.
The total test effort expended by the evaluators was 41.5 days. During that test campaign, 100% of
the total time was spent on logical tests.
2.6.3 Test configuration
The evaluator tested the TOE in the following configuration:
• Software
o V5.65.20.10F10andV5.65.20.10F12
• Hardware
o BBU shelf V9200
o AAUA9652AS35
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.
2.7 Reused Evaluation Results
There is no reuse of evaluation results in this certification.
2.8 Evaluated Configuration
The TOE is defined uniquely by its name and version number ZTE gNodeB Core Software
V5.65.20.10F12.
2.9 Evaluation Results
The evaluation lab documented their evaluation results in the [ETR], which references an 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 ZTE gNodeB Core Software
V5.65.20.10F12, to be CC Part 2 conformant, CC Part 3 conformant, and to meet the requirements
of EAL 4 augmented with ALC_FLR.2. This implies that the product satisfies the security
requirements specified in Security Target [ST].

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>.
