A. Certification
1. Preliminary Remarks
Under the BSIG1
Act, the Federal Office for Information Security (BSI) has the task of
issuing certificates for information technology products.
Certification of a product is carried out on the instigation of the vendor or a distributor,
hereinafter called the sponsor.
A part of the procedure is the technical examination (evaluation) of the product according
to the security criteria published by the BSI or generally recognised security criteria.
The evaluation is normally carried out by an evaluation facility recognised by the BSI or by
BSI itself.
The result of the certification procedure is the present Certification Report. This report
contains among others the certificate (summarised assessment) and the detailed
Certification Results.
The Certification Results contain the technical description of the security functionality of
the certified product, the details of the evaluation (strength and weaknesses) and
instructions for the user.
2. Specifications of the Certification Procedure
The certification body conducts the procedure according to the criteria laid down in the
following:
● Act on the Federal Office for Information Security1
● BSI Certification and Approval Ordinance2
● BMI Regulations on Ex-parte Costs 3
● Special decrees issued by the Bundesministerium des Innern (Federal Ministry of the
Interior)
● DIN EN ISO/IEC 17065 standard

3. Recognition Agreements
In order to avoid multiple certification of the same product in different countries a mutual
recognition of IT security certificates - as far as such certificates are based on ITSEC or
CC - under certain conditions was agreed.
3.1. European Recognition of CC – Certificates (SOGIS-MRA)
The SOGIS-Mutual Recognition Agreement (SOGIS-MRA) Version 3 became effective in
April 2010. It defines the recognition of certificates for IT-Products at a basic recognition
level and, in addition, at higher recognition levels for IT-Products related to certain SOGIS
Technical Domains only.
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels
EAL 1 to EAL 4. For "Smartcards and similar devices" a SOGIS Technical Domain is in
place. For "HW Devices with Security Boxes" a SOGIS Technical Domains is in place, too.
In addition, certificates issued for Protection Profiles based on Common Criteria are part of
the recognition agreement.
The current list of signatory nations and approved certification schemes, details on
recognition, and the history of the agreement can be seen on the website at
https://www.sogis.eu.
The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the
terms of this agreement by the related bodies of the signatory nations. A disclaimer
beneath the logo indicates the specific scope of recognition.
This certificate is recognized under SOGIS-MRA for all assurance components selected.
3.2. International Recognition of CC – Certificates (CCRA)
The international arrangement on the mutual recognition of certificates based on the CC
(Common Criteria Recognition Arrangement, CCRA-2014) has been ratified on 08
September 2014. It covers CC certificates based on collaborative Protection Profiles (cPP)
(exact use), CC certificates based on assurance components up to and including EAL 2 or
the assurance family Flaw Remediation (ALC_FLR) and CC certificates for Protection
Profiles and for collaborative Protection Profiles (cPP).
The current list of signatory nations and approved certification schemes can be seen on
the website: https://www.commoncriteriaportal.org.
The Common Criteria Recognition Arrangement logo printed on the certificate indicates
that this certification is recognised under the terms of this agreement by the related bodies
of the signatory nations. A disclaimer beneath the logo indicates the specific scope of
recognition.

Certification Report BSI-DSZ-CC-1178-2021
This certificate is recognized according to the rules of CCRA-2014, i. e. up to and including
CC part 3 EAL 2+ ALC_FLR components.
4. Performance of Evaluation and Certification
The certification body monitors each individual evaluation to ensure a uniform procedure, a
uniform interpretation of the criteria and uniform ratings.
The product Infineon Technologies AG OPTIGA™ Trusted Platform Module SLB9672_2.0
v16.10.16488.00, has undergone the certification procedure at BSI. This is a re-
certification based on BSI-DSZ-CC-1113-2021. Specific results from the evaluation
process BSI-DSZ-CC-1113-2021 were re-used.
The evaluation of the product Infineon Technologies AG OPTIGA™ Trusted Platform
Module SLB9672_2.0 v16.10.16488.00, was conducted by TÜV Informationstechnik
GmbH. The evaluation was completed on 15 September 2021. TÜV Informationstechnik
GmbH is an evaluation facility (ITSEF)5
recognised by the certification body of BSI.
For this certification procedure the sponsor and applicant is: Infineon Technologies AG.
The product was developed by: Infineon Technologies AG.
The certification is concluded with the comparability check and the production of this
Certification Report. This work was completed by the BSI.
5. Validity of the Certification Result
This Certification Report applies only to the version of the product as indicated. The
confirmed assurance package is valid on the condition that
● all stipulations regarding generation, configuration and operation, as given in the
following report, are observed,
● the product is operated in the environment described, as specified in the following report
and in the Security Target.
For the meaning of the assurance components and assurance levels please refer to CC
itself. Detailed references are listed in part C of this report.
The Certificate issued confirms the assurance of the product claimed in the Security Target
at the date of certification. As attack methods evolve over time, the resistance of the
certified version of the product against new attack methods needs to be re-assessed.
Therefore, the sponsor should apply for the certified product being monitored within the
assurance continuity program of the BSI Certification Scheme (e.g. by a re-assessment or
re-certification). Specifically, if results of the certification are used in subsequent evaluation
and certification procedures, in a system integration process or if a user's risk
management needs regularly updated results, it is recommended to perform a re-
assessment on a regular e.g. annual basis.
In order to avoid an indefinite usage of the certificate when evolved attack methods would
require a re-assessment of the products resistance to state of the art attack methods, the
maximum validity of the certificate has been limited. The certificate issued on 1 October
2021 is valid until 30 September 2026. Validity can be re-newed by re-certification.
The owner of the certificate is obliged:

1. Executive Summary
The Target of Evaluation (TOE) is the Trusted Platform Module SLB9672_2.0 v16 (or
SLB9672_2.0 in short), version v16.10.16488.00, including related guidance
documentation as described in the Security Target [6].
The TOE is an integrated circuit and software platform that provides computer
manufacturers with the core components of a subsystem used to assure authenticity,
integrity and confidentiality in e-commerce and internet communications within a Trusted
Computing Platform. The SLB9672_2.0 is a complete solution implementing the version
2.0 of the TCG Trusted Platform Module Library Family “2.0” Revision 01.59 Specification
and the TCG PC Client Specific Platform TPM Profile (PTP) Family “2.0”.
The SLB9672_2.0 uses the Serial Peripheral Interface (SPI) for the integration into existing
PC mainboards. The SLB9672_2.0 is basically a secure controller with the following added
functionality:
• Random number generator (DRBG),
• Asymmetric key generation (RSA keys with key length 1024, 2048, 3072 and 4096
bits, EC keys with key length 256 bits and 384 bits),
• Symmetric key generation (AES keys with 128, 192 and 256 bits),
• Symmetric and asymmetric key procedures (encryption/decryption, generation and
verification of digital signatures),
• Hash algorithms (SHA-1, SHA-256, SHA-384) and MAC (HMAC),
• Secure key and data storage,
• Identification and Authorization mechanisms.
The Security Target [6] is the basis for this certification. It is based on the certified
Protection Profile PC Client Specific TPM, TPM Library specification Family “2.0”, Level 0
Revision 1.38, Version: 1.2, Date: 2019-06-13, ANSSI-CC-PP-2020/01 [8].
The TOE Security Assurance Requirements (SAR) are based entirely on the assurance
components defined in Part 3 of the Common Criteria (see part C or [1], Part 3 for details).
The TOE meets the assurance requirements of the Evaluation Assurance Level EAL 4
augmented by AVA_VAN.4 and ALC_FLR.1.
The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the
Security Target [6], chapter 7.2. They are selected from Common Criteria Part 2 and some
of them are newly defined. Thus the TOE is CC Part 2 extended.
The TOE Security Functional Requirements are implemented by the following TOE

TOE Delivery
As the TOE is a security IC product it can be delivered only in form complete mounted
IC`s. Only TOEs, which have undergone and passed all the production tests are delivered
in the state user mode.
The production of the TOE wafers will be performed at TSMC Tainan (Fab14A), Taiwan
(see [6], 2.2.5).
The TOE is delivered in form of complete chips which include the hardware, the firmware,
the Endorsement Primary Seed, two RSA Endorsement Key, two ECC Endorsement Keys
and four Endorsement Certificates. The delivery of the TOE is done from a distribution
centre by postal transfer or delivery courier.
The delivery from Infineon Technologies (the TOE Manufacturer) to the Platform
manufacturer is an external delivery process and done from the site IFX Munich.
The TOE is delivered via the logistics sites: DHL Singapore, G&D Neustadt, KWE
Shanghai, and K&N Großostheim.
The individual TOE hardware is uniquely identified by its identification data. The
identification data contains the lot number, the wafer number and the coordinates of the
chip on the wafer. Each individual TOE can therefore be traced unambiguously and thus
assigned to the entire development and production process.
The delivery documentation describes all procedures that are necessary to maintain
security when distributing versions of the TOE or parts of it to the user’s site including the
necessary intermediate delivery procedures.

3. Security Policy
The Security Policy is expressed by the set of Security Functional Requirements and
implemented by the TOE. It covers the following issues:
● Cryptographic Support: generation of random numbers, generation of asymmetric
key pairs, RSA and ECC digital signature (generation and verification), RSA, ECC
and AES data encryption and decryption, key destruction, the generation of hash
values and the generation and verification of MAC values.
● Identification and Authentication: mechanisms for the identification and
authentication capability to authorize the use of a Protected Object and Protected
Capability using authentication values or policies.
● General and Test: provision and enforcement of the TPM role model, startup- and
self tests, preservation of secure state in case of failures or shutdown, and
resistance to physical manipulation or probing.
● Object Hierarchy: state control on all subjects, objects and operations, modification
of security attributes, provision of TPM hierarchy model, monitoring of data storage,
enforcement of object hierarchy.
● TOE Operation: access control on different subjects, objects and operations,
enforcement of different rules of operation and interaction between subjects and
objects, enabling and disabling of functions, enforcement of NVM restrictions, and
creation of evidence of origin.
Specific details concerning the above mentioned security policies can be found in chapter
8 of the Security Target [6].
4. Assumptions and Clarification of Scope
The assumptions defined in the Security Target and some aspects of threats and
Organisational Security Policies are not covered by the TOE itself. These aspects lead to
specific security objectives to be fulfilled and measures to be taken by the IT environment,
the user or the risk manager. The following topics are of relevance: (Details can be found
in the PP [8], chapter 5.2, and in the ST [6], chapter 5.2.)
● OE.Configuration: The TOE must be installed and configured properly for starting
up the TOE in a secure state. The security attributes of subjects and objects shall
be managed securely by the authorised user.
● OE.Locality: The developer of the host platform must ensure that trusted processes
indicate their correct locality to the TPM and untrusted processes are able to assert
just the locality 0 or Legacy only to the TPM.
● OE.Credential: The IT environment must create EK and AK credentials by
trustworthy procedures for the root of trust for reporting.
● OE.Measurement: The platform part of the root of trust for measurement provides a
representation of embedded data or program code (measured values) to the TPM
for measurement.
● OE.FieldUpgradeInfo: The developer via AGD documentation will instruct the admin
doing the upgrade how to do the upgrade and that the admin should inform the end
user regarding the Field Upgrade process , its result, whether the installed firmware
is certified or not, and the version of the certified TPM.
15 / 32
Certification Report BSI-DSZ-CC-1178-2021
● OE.ECDAA: The ECDAA issuer must support a procedure for attestation without
revealing the attestation information based on the ECDAA signing operation.
5. Architectural Information
The SLB9672_2.0 consists of hardware and firmware components.
The hardware of the TOE consists of the following parts: Security Peripherals (filters,
sensors), Core System, Memories, Coprocessors, Random number generator (RNG),
Checksum module (CRC), Interrupt module (INT), Timer (TIM), Buses (BUS), Serial
Peripheral Interface (SPI), GPIO interface and the Tick Counter.
The firmware of the TOE includes an operating system that provides the functionality
specified by the Trusted Platform Module Library specification. The chip initialisation
routine with security checks and identification mode as well as test routines for production
testing are located in a separate test ROM. The firmware also provides the mechanism for
updating the protected capabilities once the TOE is in the field as defined in the Field
Upgrade procedure in the Trusted Platform Module Library specification and User
Guidance.
The entire firmware of the TOE as defined in the PP [8] is comprised of: Boot Software
(BOS), Professional Secure Operating System (PSOS), Cryptographic Libraries (ACL,
SCL, HCL, RCL), Hardware Support Library (HSL), FieldUpgrade (CFUL), TPM2.0
Application (APP).
6. Documentation
The evaluated documentation as outlined in table 2 is being provided with the product to
the customer. This documentation contains the required information for secure usage of
the TOE in accordance with the Security Target.
Additional obligations and notes for secure usage of the TOE as outlined in chapter 10 of
this report have to be followed.
7. IT Product Testing
7.1. Developer's Test according to ATE_FUN
The tests performed by the developer according to ATE_FUN were divided into six
categories: Simulation Tests (design verification), Qualification Tests, Verification Tests,
Security Evaluation Tests, Production Tests, and Software Tests.
Different classes of tests are performed to test the TOE in a sufficient manner: Simulation
Tests (design verification), Qualification Tests, Verification Tests, Security Evaluation Tests,
Production Tests and Software Tests.
The evaluator has checked the simulation tests, qualification tests, and security evaluation
tests of the developer by sampling. The evaluator’s sample of developer tests performed
covers all portions of the TSF (security features) and related interfaces.
Overall the TSF have been tested against the functional specification, the TOE design and
the security architecture description. The tests demonstrate that the TSF performs as
specified.

7.2. Evaluator Tests – Independent Testing according to ATE_IND
The evaluator’s testing effort according to ATE_IND is described as follows, outlining the
testing approach, configuration, depth and results.
The evaluator's objective regarding this aspect was to test the functionality of the TOE as
described in the ST [6] and the design documentation, and to verify the developer's test
results by repeating developer's tests and additionally add independent tests. In the
course of the evaluation of the TOE the following classes of tests were carried out: Module
tests, Simulation tests, Emulation tests, Tests in user mode, Tests in test mode, Hardware
tests, and Software tests. With this kind of tests the entire security functionality of the TOE
was tested.
TOE test configuration:
The tests are performed with the chips OPTIGA™ Trusted Platform Module SLB9672_2.0
v16, uniquely identified by their serial numbers and version information. For the tests
different chip types are prepared. One of these types is the configuration which is finally
delivered to the user. The others contain special download functionality for test programs
or have some security mechanisms deactivated. The entire functionality is the same for all
chips.
All security features (portions of the TSF) and related interfaces were tested. Therefore no
selection criteria are applied. All security features and related interfaces are tested
regarding their functional behavior. The tests were chosen to perform at minimum one test
for each security feature of TSF and related interfaces.
Verdict for the activity:
The results of the specified and conducted independent evaluator tests confirm the TOE
functionality as described. The TSF and the interfaces were found to behave as specified.
The results of the developer tests, which have been repeated by the evaluator, matched
the results the developer stated. Overall the TSF have been tested against the functional
specification, the TOE design and the security architecture description. The tests
demonstrate that the TSF performs as specified.
Penetration Testing according to AVA_VAN:
The penetration testing was partially performed using the developer’s testing environment,
partially using the test environment of the evaluation body. All configurations of the TOE
being intended to be covered by the current evaluation were tested. The overall test result
is that no deviations were found between the expected and the actual test results;
moreover, no attack scenario with the attack potential Moderate was actually successful.
Systematic search for potential vulnerabilities and known attacks in public domain sources
has been conducted, using a list of vulnerabilities [4, AIS26], and from a methodical
analysis of the evaluation documents. Analysis has been carried out why these
vulnerabilities are not exploitable 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 rationale
is convincing in the opinion of the evaluator penetration tests are devised for some
vulnerabilities, especially to support the argument of non-practicability of the exploiting
time in case of SPA, DPA and FI attacks.
For implementation attacks the following test resources were used by the evaluator: Digital
Oscilloscope, Passive Probe, Active Differential Probe, EM Probe, Delay Generator, Laser
Fault Injection System and proprietary measuring/analyzing software.
Verdict for the sub-activity:
17 / 32
Certification Report BSI-DSZ-CC-1178-2021
The evaluator has performed penetration testing based on the systematic search for
potential vulnerabilities and known attacks in public domain sources and from the
methodical analysis of the evaluation documents. During the evaluator’s penetration
testing of potential vulnerabilities the TOE operated as specified. All potential
vulnerabilities are not exploitable in the intended environment for the TOE. The TOE is
resistant to attackers with moderate attack potential in the intended environment for the
TOE.
8. Evaluated Configuration
This certification covers the following configurations of the TOE:
Trusted Platform Module SLB9672_2.0 v16 (or SLB9672_2.0 in short), version
v16.10.16488.00, including related guidance documentation as described in the Security
Target [6] and Databook [10].
9. Results of the Evaluation
9.1. CC specific results
The Evaluation Technical Report (ETR) [7] was provided by the ITSEF according to the
Common Criteria [1], the Methodology [2], the requirements of the Scheme [3] and all
interpretations and guidelines of the Scheme (AIS) [4] as relevant for the TOE.
The Evaluation Methodology CEM [2] was used and guidance specific for the technology
of the product [4] (AIS 34).
The following guidance specific for the technology was used:
(i) The Application of Common Criteria to Integrated Circuits.
(ii) For RNG assessment the scheme interpretations AIS 20 and AIS 31 were used
(see [4]).
As a result of the evaluation the verdict PASS is confirmed for the following assurance
components:
● All components of the EAL 4 package including the class ASE as defined in the CC (see
also part C of this report)
● The components AVA_VAN.4 and ALC_FLR.1 augmented for this TOE evaluation.
As the evaluation work performed for this certification procedure was carried out as a re-
evaluation based on the certificate BSI-DSZ-CC-1113-2021, re-use of specific evaluation
tasks was possible. The software version has changed from v15.20.15686.00 for the
predecessor to the version v16.10.16488.00 for the current TOE. The new version
contains (partially security-relevant) updates and fixes for the TPM operating system,
FieldUpgrade (CFUL), and TPM2.0 Application (APP) parts of the TOE’s software.
The evaluation has confirmed:
● PP Conformance: PC Client Specific TPM, TPM Library specification Family “2.0”,
Level 0 Revision 1.38, Version: 1.2, Date: 2019-06-13, ANSSI-
CC-PP-2020/01 [8]
● for the Functionality: PP conformant
Common Criteria Part 2 extended
18 / 32
BSI-DSZ-CC-1178-2021 Certification Report
● for the Assurance: Common Criteria Part 3 conformant
EAL 4 augmented by AVA_VAN.4 and ALC_FLR.1
For specific evaluation results regarding the development and production environment see
annex B in part D of this report.
The results of the evaluation are only applicable to the TOE as defined in chapter 2 and
the configuration as outlined in chapter 8 above.
9.2. Results of cryptographic assessment
The strength of the cryptographic algorithms was not rated in the course of this certification
procedure (see BSIG Section 9, Para. 4, Clause 2). But cryptographic functionalities with a
security level of lower than 100 bits can no longer be regarded as secure without
considering the application context. Therefore, for these functionalities it shall be checked
whether the related crypto operations are appropriate for the intended system. Some
further hints and guidelines can be derived from the 'Technische Richtlinie BSI TR-02102'
(https://www.bsi.bund.de).
The table 7 in annex C of part D of this report gives an overview of the cryptographic
functionalities inside the TOE to enforce the security policy and outlines its rating from
cryptographic point of view. Any Cryptographic Functionality that is marked in column
'Security Level above 100 Bits' of the following table with 'no' achieves a security level of
lower than 100 Bits (in general context) only.
Detailed results on conformance and non-conformance have been compiled into the report
[18].
10. Obligations and Notes for the Usage of the TOE
The documents as outlined in table 2 contain necessary information about the usage of the
TOE and all security hints therein have to be considered. In addition all aspects of
Assumptions, Threats and OSPs as outlined in the Security Target not covered by the TOE
itself need to 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. In order for the evolution of attack methods and
techniques to be covered, he should define the period of time until a re-assessment of the
TOE is required and thus requested from the sponsor of the certificate.
The limited validity for the usage of cryptographic algorithms as outlined in chapter 9 has
to be considered by the user and his system risk management process, too.
If available, certified updates of the TOE should be used. If non-certified updates or
patches are available the user of the TOE should request the sponsor to provide a re-
certification. In the meantime a risk management process of the system using the TOE
should investigate and decide on the usage of not yet certified updates and patches or
take additional measures in order to maintain system security.
Especially the following notice from the Security Target [6] should be taken into account:
The TPM includes two ECC Endorsement Keys (EK) and two RSA Endorsement Keys
(EK) and the Endorsement Primary Seed (EPS), which can be used to generate additional
EKs alternatively. The two ECC Endorsement Keys, the two RSA Endorsement Keys and
the Endorsement Primary Seed are generated outside the TPM with the TPM
19 / 32
Certification Report BSI-DSZ-CC-1178-2021
Personalization Certification Authority (TPM-CA) located within the secure production area
of the TOE in a secure room. The RSA Endorsement Key is generated from a proved
random number generator by the HSM-PDG and not derived from the Endorsement Seed.
The Endorsement Keys RSA EK and ECC EK, personalized by the TPM vendor, are not
visible and changeable for the user, but can be deactivated with the TPM2_EvictControl()
and TPM2_FlushContext commands, and can be activated again with the
TPM2_CreatePrimary command by the user. As these personalized Endorsement Keys
should be used only for the identification of the TPM vendor, the user shall not use these
keys for other functions.
During the production phase the so called unique ID is computed, which is unique across
all Infineon TPMs and stored as NV index in a reserved Infineon NV index handle area for
TPM OEMs. The TPM unique ID can not be changed and is preserved across field
upgrades.
