2.1 European Recognition of ITSEC/CC - Certificates
The SOGIS-Mutual Recognition Agreement (MRA) for certificates based on ITSEC
became initially effective in March 1998.
This agreement on the mutual recognition of IT security certificates was extended in April
1999 to include certificates based on the Common Criteria for the Evaluation Assurance
Levels (EAL 1 – EAL 7). This agreement was signed by the national bodies of Finland,
France, Germany, Greece, Italy, The Netherlands, Norway, Spain, Sweden and the United
Kingdom. The German Federal Office for Information Security (BSI) recognises certificates
issued by the national certification bodies of France and United Kingdom, and from The
Netherlands since January 2009 within the terms of this agreement.

1 Executive Summary
The Target of Evaluation (TOE) is the Infineon Smart Card IC (Security Controller)
SLE66CX366PE / M1528-k11, SLE66CX206PE / M1506-k11 and SLE66CX186PE /
M1503-k11 all with optional libraries RSA2048 V1.6 and ECC V1.1 and with specific IC
dedicated software . All products of this TOE were already been successfully CC EAL5+
certified in the different design version by the BSI. The direct recertification reference for
this TOE the BSI process BSI-DSZ-CC-0470-2008 including the library versions RSA
Version 1.5 and ECC Version 1.1. The main differences to the forerunner are the different
implemented memory sizes respectively blocked size, the new silicon production site, the
STS update and the new RSA library version.
The ICs consists of a dedicated non standard microprocessor (CPU) with a MMU (Memory
Management Unit), several different memories, security logic, a timer, an interrupt-
controlled I/O interface, an AIS31-compliant RNG (Random Number Generator), and a
checksum module (CRC module). Further components are integrated on the chip too. For
fast RSA2048 cryptographic operations performance the TOE has the Advanced
Cryptographic Engine (ACE) component implemented. The TOE’s block diagram is shown
in Figure 1 of the Security Target [6, chapter 2.1].
This TOE is intended to be used in smart cards particularly for security relevant
applications, including high speed security authentication, data encryption or electronic
signature. The TOE offers a new, improved standard of integrated security features,
thereby meeting the requirements of all smart card applications with contact-based and
contactless interface such as information integrity, access control, mobile telephone, as
well as uses in electronic funds transfer and healthcare systems. Several security features
independently implemented in hardware or controlled by software will be provided to
ensure proper operations and integrity and confidentiality of stored data.
The crypto library RSA2048, the crypto library ECC and the RMS library provide some
functionality via an API to the Smartcard Embedded Software and STS firmware for test
purpose. The STS is implemented in a separated Test-ROM being part of the TOE. The
RSA2048 library supports operation size from 512 bits to 2048 bits. Only key sizes from
1024 bits up to 2048 bits are within the scope of this evaluation. The ECC library can
perform EC operations on elliptic curve parameters with key lengths up to 533 bits.
Included in the evaluation are only operations with key length of 192 to 521 bits. The
Smartcard Embedded Software is not part of the TOE.
The user has the possibility to tailor the software part of the TOE during the manufacturing
process by deselecting one or both crypto libraries. Thus the TOE can be delivered
including the functionality of the ECC crypto library or including the functionality of the
RSA2048 crypto library or including the functionality of the ECC and RSA2048 crypto
libraries or including no crypto library. Two modules for cryptographic operations are
implemented on the TOE: The well known Advanced Crypto Engine (ACE) (Advanced
Crypto Engine) for calculation of asymmetric algorithms like RSA and elliptic curve (EC)
and the Cryptographic Unit (DDES) for Dual Key DES calculations. These modules are
especially designed for Chipcard applications with respect to the security and power
consumption. The DDES module computes the complete DES algorithm within a few clock
cycles and is especially designed to counter attacks like DPA or EMA. The TOE includes
also functionality to calculate single DES operations, but part of the evaluation is the
Triple-DES operation only. For more detail please refer to the Security Target [6, chapter
2.1].

Table 2: Deliverables of the TOE
The hardware part of the TOE is identified by SLE66CX366PE / M1528-k11,
SLE66CX206PE / M1506-k11, or SLE66CX186PE / M1503-k11. Another characteristic of
the TOE is a serial number (chip identification number). This serial number is chip specific
as the chip type, lot number, wafer, chip coordinates on the wafer, production date,
production site (e.g. upper nibble of (08000AH) “7” stands for Infineon’s IC fabrication in
Kulim/Malaysia “k”) and design step (e.g. “0B” at address (080009H) stands for design
step “11”) are part of the number. The serial number, which is accessible in the chip
identification mode, is linked to the version number. For the format of the serial number
see [12, chapter 7.3.5] and [11, chapter 6.7].
The chip type byte identifies the different versions in the following Table 3.

The RSA2048 library and the ECC library, as separate software parts of the TOE, as well
as RMS and STS, as firmware parts of the TOE, are identified by their unique version
numbers. The TOE can be delivered with or without the RSA library and / or the ECC
library.
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:
The security policy of the TOE is to provide basic Security Functions to be used by the
smart card operating system and the smart card application thus providing an overall
smart card system security. Therefore, the TOE will implement an algorithm to ensure the
confidentiality of plain text data by encryption and to support secure authentication
protocols and it will provide a random number generator.
As the TOE is a hardware security platform, the security policy of the TOE is also to
provide protection against leakage of information (e.g. to ensure the confidentiality of
15 / 40
Certification Report BSI-DSZ-CC-0554-2009
cryptographic keys during Triple-DES cryptographic functions performed by the TOE),
against physical probing, against malfunctions, against physical manipulations and against
abuse of functionality. Hence the TOE shall maintain the integrity and the confidentiality of
data stored in the memory of the TOE and maintain the integrity, the correct operation and
the confidentiality of Security Functions (security mechanisms and associated functions)
provided by the TOE.
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 by the TOE-Environment. The following topics are
of relevance: Usage of Hardware Platform, Treatment of User Data, Protection during TOE
Development and Production, Protection during Packaging, Finishing and Personalisation.
Details can be found in the Security Target [6, chapter 4.2].
5 Architectural Information
The TOEs are integrated circuits (IC) providing a platform to a smart card operating
system and smart card application software. A top level block diagram and a list of
subsystems can be found within the TOE description of the Security Target [6, chapter
2.1]. The complete hardware description and the complete instruction set of the TOE is to
be found in the Data Book [12] and other guidance documents delivered to the customer,
see table 2.
For the implementation of the TOE Security Functions basically the central processing unit
(CPU) with memory management unit (MMU), RAM, ROM, EEPROM, security logic,
interrupt module, bus system, Random Number Generator (RNG) and the two modules for
cryptographic operations of the chip are used. Security measures for physical protection
are realised within the layout of the whole circuitry.
The Special Function Registers, the CPU instructions and the various on-chip memories
provide the interface to the software using the Security Functions of the TOE.
The TOE IC Dedicated Test Software (STS), stored on the chip, is used for testing
purposes during production only and is completely separated from the use of the
embedded software by disabling before TOE delivery.
The TOE IC Dedicated Support Software (RMS), stored on the chip, is used for EEPROM
programming and Security Function testing. It is stored by the TOE manufacturer in a
reserved area of the normal user ROM and can be used by the users embedded software.
The software part of the TOE consists of the RSA2048 library and the ECC library. The
RSA2048 library and the ECC library are delivered as source code and in this way
integrated in the user software. The TOE includes also functionality to calculate single
DES operations, but part of the evaluation is the Triple-DES operation only.
6 Documentation
The evaluated documentation as outlined in table 2 is together provided with the product.
This documentation contains the required information for secure usage of the TOE in
accordance with the Security Target.

BSI-DSZ-CC-0554-2009 Certification Report
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
The tests performed by the developer were divided into six categories:
● Simulation tests: These tests are performed before starting the production to develop
the technology for the production and to define the process parameters.
● Qualification tests: These tests are performed after the first production of chips. The
tests are performed in test mode. With these tests the influence of temperature,
frequency, and voltage on the security functions are tested in detail.
● Verification tests: These tests are performed in normal mode and check the
functionality in the end user environment. The results of the qualification and
verification tests are the basis on which it is decided, whether the TOE is released to
production.
● Security evaluation tests: These tests are performed in normal mode and check the
security mechanisms aiming on the security functionality and the effectiveness of the
mechanisms. The random numbers are tested as required by AIS 31 and fulfill the
criteria.
● Production tests: These tests are performed at each TOE before delivery. The aim of
the production tests is to check whether each chip is functioning correctly.
● Penetration Tests: Penetration Tests are performed to find security flaws in the product.
The developer tests cover all Security Functions and all security mechanisms as identified
in the functional specification, the high level design and the low level design. Chips from
the production site Kulim (see part D, annex A of this report) were used for tests.
The evaluators testing effort can be summarised into the following classes of tests: Module
tests, Simulation tests, Emulation tests, Tests in user mode, Tests in test mode and
Hardware tests. The evaluators performed independent tests to supplement, augment and
to verify the tests performed by the developer by sampling. Besides repeating exactly the
developers tests, test parameters were varied and additional analysis was done. With
these kind of tests performed in the developer’s testing environment the entire security
functionality of the TOE was verified. Overall the evaluators have tested the TSF
systematically against the functional specification, the high-level design and the low-level
design.
The evaluators supplied evidence that the current version of the TOE with production line
indicator “7” for Kulim (Malaysia) provides the Security Functions as specified.
For this re-evaluation the evaluators re-assessed the penetration testing and confirmed the
results from the previous certification procedure BSI-DSZ-CC-0470-2008 where they took
all Security Functions into consideration. Intensive penetration testing was performed at
that time to consider the physical tampering of the TOE using highly sophisticated
equipment and expertised know-how. Specific additional penetration attacks were
performed in the course of this evaluation.

8 Evaluated Configuration
The SLE66CX366PE, the SLE66CX206PE, and the SLE66CX186PE are identically from
hardware perspective. The difference is that in the SLE66CX206PE and the
SLE66CX186PE the memory is blocked to a smaller size. All types can be distinguished
by a different chip identification. The difference in the memory size does not influence the
security of the TOE as neither an asset nor a security enforcing function is affected.
Therefore the products are evaluated together.
Therefore the TOE is delivered in the following fixed configurations:
● SLE66CX366PE / M1528-k11 with/or without RSA 2048 and/or ECC (produced in
Kulim),
● SLE66CX206PE / M1506-k11 with/or without RSA 2048 and/or ECC (produced in
Kulim),
● SLE66CX186PE / M1503-k11 with/or without RSA 2048 and/or ECC (produced in
Kulim).
This certification covers the above mentioned configurations with the specific IC Dedicated
Software and with production line indicator “7” for Kulim (Malaysia). After delivery the TOE
only features one fixed configuration (user mode), which cannot be altered by the user.
The TOE was tested in this configuration. All the evaluation and certification results
therefore are only effective for this version of the TOE. For all evaluation activities
performed in test mode, there was a rationale why the results are valid for the user mode,
too.
9 Results of the Evaluation
9.1 CC specific results
The Evaluation Technical Report (ETR) [8] 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 for those components up to EAL4
extended by advice of the Certification Body for components beyond EAL 4 and guidance
specific for the technology of the product [4] (AIS 34).
The following guidance specific for the technology was used:
● The Application of CC to Integrated Circuits
● The Application of Attack Potential to Smartcards
● Functionality classes and evaluation methodology of physical random number
generators
(see [4], AIS 25, AIS 26, AIS 31) were used.
As a result of the evaluation the verdict PASS is confirmed for the following assurance
components:
● All components of the EAL 5 package including the class ASE as defined in the CC
(see also part C of this report)
18 / 40
BSI-DSZ-CC-0554-2009 Certification Report
● The components ALC_DVS.2 (Sufficiency of security measures), AVA_MSU.3
(validation of analysis) and AVA_VLA.4 (Highly resistant) augmented for this TOE
evaluation.
● All components claimed in the Security Target [6, chapter 6 and defined in the CC (see
also part C of this report)
As the evaluation work performed for this certification procedure was carried out as a re-
evaluation based on the certificate BSI-DSZ-CC-0470-2008, re-use of specific evaluation
tasks was possible. The focus of this re-evaluation was on implemented memory sizes, the
new silicon production site, the STS update and the new RSA library version.
The evaluation has confirmed:
● PP Conformance: Smartcard IC Platform Protection Profile, Version 1.0,
July 2001, Eurosmart, BSI-PP-0002-2001 [7]
● for the Functionality: PP conformant plus product specific extensions
Common Criteria Part 2 extended
● for the Assurance: Common Criteria Part 3 conformant
EAL 5 augmented by
ALC_DVS.2, AVA_MSU.3 and AVA_VLA.4
● The following TOE Security Functions fulfil the claimed Strength of Function : high
SEF2 – Phase management with test mode lock-out,
SEF3 – Protection against snooping,
SEF4 – Data encryption and data disguising,
SEF5 – Random number generation
In order to assess the strength of function the scheme interpretations AIS 25, 26 and AIS
31 (see [4]) were used. 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 following cryptographic algorithms are used by the TOE to enforce its security policy:
● algorithms for the encryption and decryption: RSA, ECC, Triple-DES
● This holds for the following security functions: SF9
The strength of the cryptographic algorithms was not rated in the course of this evaluation
(see BSIG Section 4, Para. 3, Clause 2). But cryptographic functions with a security level
of 80 bits or lower can no longer be regarded as secure against attacks with high attack
potential without considering the application context. Therefore for these functions 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' (www.bsi.bund.de) [27]
The cryptographic functions 2-key Triple DES (2TDES) and RSA 1024 provided by the
TOE have got a security level of maximum 80 Bits (in general context).

10 Obligations and notes for the usage of the TOE
The operational documents as outlined in table 2 contain necessary information about the
usage of the TOE and all security hints therein have to be considered.
The TOE is delivered to the Smartcard Embedded Software Developer and the Card
Manufacturer. The actual end user obtains the TOE from the Card Manufacturer together
with the application which runs on the TOE. In addition, the following aspects need to be
fulfilled when using the TOE:
The operational documents as outlined in Table 2, deliverables of the TOE, contain
necessary information about the usage of the TOE and all security hints therein have to be
considered.
All security hints described in the user guidance documentation [12]..[16] and the delivered
application notes [17]..[26] have to be considered. For secure usage of the TOE the
fulfilment of the assumptions about the environment in the Security Target [ST] and
especially the recommendations of the Security Programmers Manual [13] have to be
taken into account.
The TOE does not implement a padding scheme for the RSA signature
creation/verification. This has to be implemented by the embedded software. To counter
known attacks against incorrect padding a complete check of padding regarding
correctness is mandatory.
If the key parameters of the signature generation are stored in the RAM, a Bellcore attack
is possible. Therefore the embedded software has to check the consistency of the key
parameters handed over by the RSA signature generation function after call of the
function, e.g. by means of a CRC.
As the bit length of the randomisation by the scalar multiplication and inversion is adjusted
to be 24 bit or 533 – “bit length of the curve” bit, it is strongly recommended for the ECC
library that only curves with bit length up to 521 bit are used, because only for these
curves it is examined that the randomisation is sufficient to counter attacks.
Because of a possible fault injection attack on the ECDSA signature verification, the
operating system developer has to check the verify result by e.g. performing the verify
function twice, if the verification result is used for a security critical operation.

C Excerpts from the Criteria
CC Part1:
Conformance Claim (chapter 9.4)
„The conformance claim indicates the source of the collection of requirements that is met
by a PP or ST that passes its evaluation. This conformance claim contains a CC
conformance claim that:
● describes the version of the CC to which the PP or ST claims conformance.
● describes the conformance to CC Part 2 (security functional requirements) as either:
– CC Part 2 conformant - A PP or ST is CC Part 2 conformant if all SFRs in that PP
or ST are based only upon functional components in CC Part 2, or
– CC Part 2 extended - A PP or ST is CC Part 2 extended if at least one SFR in that
PP or ST is not based upon functional components in CC Part 2.
● describes the conformance to CC Part 3 (security assurance requirements) as either:
– CC Part 3 conformant - A PP or ST is CC Part 3 conformant if all SARs in that PP
or ST are based only upon assurance components in CC Part 3, or
– CC Part 3 extended - A PP or ST is CC Part 3 extended if at least one SAR in that
PP or ST is not based upon assurance components in CC Part 3.
Additionally, the conformance claim may include a statement made with respect to
packages, in which case it consists of one of the following:
● Package name Conformant - A PP or ST is conformant to a pre-defined package (e.g.
EAL) if:
– the SFRs of that PP or ST are identical to the SFRs in the package, or
– the SARs of that PP or ST are identical to the SARs in the package.
● Package name Augmented - A PP or ST is an augmentation of a predefined package if:
– the SFRs of that PP or ST contain all SFRs in the package, but have at least one
additional SFR or one SFR that is hierarchically higher than an SFR in the package.
– the SARs of that PP or ST contain all SARs in the package, but have at least one
additional SAR or one SAR that is hierarchically higher than an SAR in the
package.
Note that when a TOE is successfully evaluated to a given ST, any conformance claims of
the ST also hold for the TOE. A TOE can therefore also be e.g. CC Part 2 conformant.
Finally, the conformance claim may also include two statements with respect to Protection
Profiles:
● PP Conformant - A PP or TOE meets specific PP(s), which are listed as part of the
conformance result.
● Conformance Statement (Only for PPs) - This statement describes the manner in which
PPs or STs must conform to this PP: strict or demonstrable. For more information on
this Conformance Statement, see Annex A.

Evaluation assurance levels (chapter 8)
“ The Evaluation Assurance Levels (EALs) provide an increasing scale that balances the
level of assurance obtained with the cost and feasibility of acquiring that degree of
assurance. The CC approach identifies the separate concepts of assurance in a TOE at
the end of the evaluation, and of maintenance of that assurance during the operational use
of the TOE.
It is important to note that not all families and components from CC Part 3 are included in
the EALs. This is not to say that these do not provide meaningful and desirable
assurances. Instead, it is expected that these families and components will be considered
for augmentation of an EAL in those PPs and STs for which they provide utility.”
Evaluation assurance level (EAL) overview (chapter 8.1)
“Table 1 represents a summary of the EALs. The columns represent a hierarchically
ordered set of EALs, while the rows represent assurance families. Each number in the
resulting matrix identifies a specific assurance component where applicable.
As outlined in the next Section, seven hierarchically ordered evaluation assurance levels
are defined in the CC for the rating of a TOE's assurance. They are hierarchically ordered
inasmuch as each EAL represents more assurance than all lower EALs. The increase in
assurance from EAL to EAL is accomplished by substitution of a hierarchically higher
assurance component from the same assurance family (i.e. increasing rigour, scope,
and/or depth) and from the addition of assurance components from other assurance
families (i.e. adding new requirements).
These EALs consist of an appropriate combination of assurance components as described
in Chapter 7 of this CC Part 3. More precisely, each EAL includes no more than one
component of each assurance family and all assurance dependencies of every component
are addressed.
While the EALs are defined in the CC, it is possible to represent other combinations of
assurance. Specifically, the notion of “augmentation” allows the addition of assurance
components (from assurance families not already included in the EAL) or the substitution
of assurance components (with another hierarchically higher assurance component in the
same assurance family) to an EAL. Of the assurance constructs defined in the CC, only
EALs may be augmented. The notion of an “EAL minus a constituent assurance
component” is not recognised by the standard as a valid claim. Augmentation carries with
it the obligation on the part of the claimant to justify the utility and added value of the
added assurance component to the EAL. An EAL may also be augmented with extended
assurance requirements.

BSI-DSZ-CC-0554-2009 Certification Report
Evaluation assurance level 1 (EAL1) - functionally tested (chapter 8.3)
“Objectives
EAL1 is applicable where some confidence in correct operation is required, but the threats
to security are not viewed as serious. It will be of value where independent assurance is
required to support the contention that due care has been exercised with respect to the
protection of personal or similar information.
EAL1 requires only a limited security target. It is sufficient to simply state the SFRs that the
TOE must meet, rather than deriving them from threats, OSPs and assumptions through
security objectives.
EAL1 provides an evaluation of the TOE as made available to the customer, including
independent testing against a specification, and an examination of the guidance
documentation provided. It is intended that an EAL1 evaluation could be successfully
conducted without assistance from the developer of the TOE, and for minimal outlay.
An evaluation at this level should provide evidence that the TOE functions in a manner
consistent with its documentation.”
Evaluation assurance level 2 (EAL2) - structurally tested (chapter 8.4)
“Objectives
EAL2 requires the co-operation of the developer in terms of the delivery of design
information and test results, but should not demand more effort on the part of the
developer than is consistent with good commercial practise. As such it should not require a
substantially increased investment of cost or time.
EAL2 is therefore applicable in those circumstances where developers or users require a
low to moderate level of independently assured security in the absence of ready
availability of the complete development record. Such a situation may arise when securing
legacy systems, or where access to the developer may be limited.”
Evaluation assurance level 3 (EAL3) - methodically tested and checked (chapter 8.5)
“Objectives
EAL3 permits a conscientious developer to gain maximum assurance from positive
security engineering at the design stage without substantial alteration of existing sound
development practises.
EAL3 is applicable in those circumstances where developers or users require a moderate
level of independently assured security, and require a thorough investigation of the TOE
and its development without substantial re-engineering.”

Evaluation assurance level 4 (EAL4) - methodically designed, tested, and reviewed
(chapter 8.6)
“Objectives
EAL4 permits a developer to gain maximum assurance from positive security engineering
based on good commercial development practises which, though rigorous, do not require
substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at
which it is likely to be economically feasible to retrofit to an existing product line.
EAL4 is therefore applicable in those circumstances where developers or users require a
moderate to high level of independently assured security in conventional commodity TOEs
and are prepared to incur additional security-specific engineering costs.”
Evaluation assurance level 5 (EAL5) - semiformally designed and tested (chapter 8.7)
“Objectives
EAL5 permits a developer to gain maximum assurance from security engineering based
upon rigorous commercial development practises supported by moderate application of
specialist security engineering techniques. Such a TOE will probably be designed and
developed with the intent of achieving EAL5 assurance. It is likely that the additional costs
attributable to the EAL5 requirements, relative to rigorous development without the
application of specialised techniques, will not be large.
EAL5 is therefore applicable in those circumstances where developers or users require a
high level of independently assured security in a planned development and require a
rigorous development approach without incurring unreasonable costs attributable to
specialist security engineering techniques.”
Evaluation assurance level 6 (EAL6) - semiformally verified design and tested
(chapter 8.8)
“Objectives
EAL6 permits developers to gain high assurance from application of security engineering
techniques to a rigorous development environment in order to produce a premium TOE for
protecting high value assets against significant risks.
EAL6 is therefore applicable to the development of security TOEs for application in high
risk situations where the value of the protected assets justifies the additional costs.”

BSI-DSZ-CC-0554-2009 Certification Report
Evaluation assurance level 7 (EAL7) - formally verified design and tested
(chapter 8.9)
“Objectives
EAL7 is applicable to the development of security TOEs for application in extremely high
risk situations and/or where the high value of the assets justifies the higher costs. Practical
application of EAL7 is currently limited to TOEs with tightly focused security functionality
that is amenable to extensive formal analysis.”
Class AVA: Vulnerability assessment (chapter 16)
“The AVA: Vulnerability assessment class addresses the possibility of exploitable
vulnerabilities introduced in the development or the operation of the TOE.”
Vulnerability analysis (AVA_VAN) (chapter 16.1)
"Objectives
Vulnerability analysis is an assessment to determine whether potential vulnerabilities
identified, during the evaluation of the development and anticipated operation of the TOE
or by other methods (e.g. by flaw hypotheses or quantitative or statistical analysis of the
security behaviour of the underlying security mechanisms), could allow attackers to violate
the SFRs.
Vulnerability analysis deals with the threats that an attacker will be able to discover flaws
that will allow unauthorised access to data and functionality, allow the ability to interfere
with or alter the TSF, or interfere with the authorised capabilities of other users.”
