1.6 TOE OVERVIEW
1.6.1 TOE description
IAS is a Java Card application that provides a Secure Signature Creation Device – SSCD - as defined in the
DIRECTIVE 1999/93/EC of the European Parliament and of the Council of 13 December 1999 on a
Community Framework for electronic signatures.
[PP-SSCD] defines protection profiles for SSCD:
 [PP-SSCD-KI] is a protection profile for an SSCD Type 2 with SCD key import and signature
creation.
 [PP-SSCD-KG] is a protection profile for an SSCD Type 3 with SCD/SVD key generation and
signature creation.
In this document the terminology of [CWA-14169] is used. In particular, the Signatory's Reference
Authentication Data (RAD) is the PIN stored in the card and the Signatory's Verification Authentication Data
(VAD) is the PIN provided by the user.
The IAS application can be used in contact or contactless mode.
The IAS application supports:
 The import of the SCD via a trusted channel
 The (on-board) generation of SCD/SVD pairs
 The generation of electronic signatures
 The export of the SVD to the certification generation application (CGA)
IAS is aimed to create legal valid signatures and therefore provides mechanisms to ensure the secure
signature creation as:
 Authentication of the signatory by PIN or BioPIN,
 Authentication of the administrator (mutual authentication):
 Symmetric scheme with TDES or AES
 Asymmetric scheme with Diffie-Hellman based on RSA or elliptic curves
 Integrity of access conditions to protected data (SCD, RAD),
 Integrity of the data to be signed (DTBS),
 External communication protection against disclosure and corruption (secure messaging),
 Access control to commands and data by authorized users.
1.7 TOE BOUNDARIES
The Target of Evaluation (TOE) is the Secure Signature Creation Device - SSCD - IAS defined by:
- The underlying Integrated Circuit
- The MultiApp V31 platform (JavaCard platform)
- The IAS Application.
Figure 1: TOE Boundaries gives a description of the TOE and its boundaries.

1.8 TOE LIFE-CYCLE
1.8.1 Four phases
The TOE life cycle is described in terms of the four life cycle phases:
Phase 1 “Development”:
The TOE is developed in phase 1. The IC developer develops the integrated circuit, the IC Dedicated
Software and the guidance documentation associated with these TOE components.
The Embedded Software developer uses the guidance documentation for the integrated circuit and the
guidance documentation for relevant parts of the IC Dedicated Software and develops the IC Embedded
Software (operating system), the SSCD application and the guidance documentation associated with these
TOE components.
Phase 2 “Manufacturing”:
In a first step the TOE integrated circuit is produced containing the chip Dedicated Software and the parts of
the chip Embedded Software in the nonvolatile non-programmable memories (ROM). The IC manufacturer
writes the IC Identification Data onto the chip to control the IC as SSCD material during the IC manufacturing
and the delivery process to the SSCD manufacturer. The IC is securely delivered from the IC manufacturer
to the SSCD manufacturer.
The SSCD manufacturer has the following tasks:
 Initialization: adding the parts of the IC Embedded Software (NVM ES) to the EEPROM,
 Pre-personalization: initialization of the SSCD application,
Phase 3 Personalization of the TOE:

3. SECURITY PROBLEM DEFINITION
3.1 INTRODUCTION
3.1.1 Assets
The assets of the TOE are those defined in [PP-SSCD-KI], [PP-SSCD-KG]. The present Security Target
deals with the assets of [PP-SSCD-KI] and [PP-SSCD-KG].
The assets of [PP-JCS-Open] are studied in [ST-PLTF].
D.SCD
SCD: private key used to perform an electronic signature operation (confidentiality of the SCD must be
maintained).
D.SVD
SVD: public key linked to the SCD and used to perform an electronic signature verification (integrity of the
SVD when it is exported must be maintained).
D.DTBS
DTBS and DTBS-representation: set of data, or its representation which is intended to be signed (Their
integrity must be maintained).
D.VAD
VAD: PIN code entered by the End User to perform a signature operation (confidentiality and authenticity of
the VAD as needed by the authentication method employed are required)
D.SSCD
Signature-creation function of the SSCD using the SCD: (The quality of the function must be maintained so
that it can participate to the legal validity of electronic signatures)
D.RAD
RAD: Reference PIN code used to identify and authenticate the End User (integrity and confidentiality of
RAD must be maintained)
D.SIG
Electronic signature: (Unforgeability of electronic signatures must be assured).
3.1.2 Subjects
Subject Definition

S.Admin User who is in charge to perform the TOE initialisation, TOE personalisation or other TOE
administrative functions.
S.Signatory or
S.Sigy
User who holds the TOE and uses it on his own behalf or on behalf of the natural or legal
person or entity he represents.
3.1.3 Threat agent
Subject Definition
S.OFFCARD Attacker. A human or a process acting on his behalf being located outside the TOE. The

main goal of the S.OFFCARD attacker is to access Application sensitive information. The
attacker has a high level potential attack and knows no secret.
3.2 ASSUMPTIONS
The assumptions describe the security aspects of the environment in which the TOE will be used or is
intended to be used.
A.CGA
Trustworthy certification-generation application
The CGA protects the authenticity of the signatory’s name and the SVD in the qualified certificate by an
advanced signature of the CSP.
A.SCA
Trustworthy signature-creation application
The signatory uses only a trustworthy SCA. The SCA generates and sends the DTBS-representation of data
the signatory wishes to sign in a form appropriate for signing by the TOE.
A.SCD_Generate
Trustworthy SCD/SVD generation
If a party other than the signatory generates the SCD/SVD-pair of a signatory, then
(a) this party will use a SSCD for SCD/SVD-generation,
(b) confidentiality of the SCD will be guaranteed until the SCD is under the sole control of the signatory and
(c) the SCD will not be used for signature-creation until the SCD is under the sole control of the signatory.
(d) The generation of the SCD/SVD is invoked by authorized users only
(e) The SSCD Type1 ensures the authenticity of the SVD it has created an exported
3.3 THREATS
The TOE is required to counter the threats described hereafter.
A threat agent wishes to abuse the assets either by functional attacks or by environmental manipulation, by
specific hardware manipulation, by a combination of hardware and software manipulations or by any other
type of attacks.
The threats of the TOE are those defined in [PP-SSCD-KI], [PP-SSCD-KG].The present Security Target
deals with the threats of [PP-SSCD-KI] and [PP-SSCD-KG].
The assets of [PP-JCS-Open] are studied in [ST-PLTF].
T.Hack_Phys
Physical attacks through the TOE interfaces
An attacker interacts with the TOE interfaces to exploit vulnerabilities, resulting in arbitrary security
compromises. This threat addresses all the assets.
T.SCD_Divulg
Storing ,copying, and releasing of the signature-creation data
An attacker can store, copy, the SCD outside the TOE. An attacker can release the SCD during generation,
storage and use for signature-creation in the TOE.
T.SCD_Derive
Derive the signature-creation data
An attacker derives the SCD from public known data, such as SVD corresponding to the SCD or signatures
created by means of the SCD or any other data communicated outside the TOE, which is a threat against the
secrecy of the SCD.

Classification Level Public Pages 59
ST Applicable on: November 2014 Page : 19 / 59
Content of this document shall not be modified or partially reused without prior written consent of Gemalto
T.Sig_Forgery
Forgery of the electronic signature
An attacker forges the signed data object maybe together with its electronic signature created by the TOE
and the violation of the integrity of the signed data object is not detectable by the signatory or by third
parties. The signature generated by the TOE is subject to deliberate attacks by experts possessing a high
attack potential with advanced knowledge of security principles and concepts employed by the TOE.
T.Sig_Repud
Repudiation of Signatures
If an attacker can successfully threaten any of the assets, then the non-repudiation of the electronic
signature is compromised. This results in the signatory being able to deny having signed data using the SCD
in the TOE under his control even if the signature is successfully verified with the SVD contained in his
un-revoked certificate.
T.SVD_Forgery
Forgery of signature-verification data
An attacker forges the SVD presented by the TOE to the CGA. This result in loss of SVD integrity in the
certificate of the signatory.
T.DTBS_Forgery
Forgery of the DTBS-representation
An attacker modifies the DTBS-representation sent by the SCA. Thus the DTBS-representation used by the
TOE for signing does not match the DTBS the signatory intended to sign.
T.SigF_Misuse
Misuse of the signature creation function of the TOE
An attacker misuses the signature-creation function of the TOE to create SDO for data the signatory has not
decided to sign. The TOE is subject to deliberate attacks by experts possessing a high attack potential with
advanced knowledge of security principles and concepts employed by the TOE.
3.4 ORGANIZATIONAL SECURITY POLICIES
The Secure Signature Creation Device usage is for advanced electronic signature. So it is mandatory to
follow the organisational security policy proposed by [PP-SSCD-KI] and [PP-SSCD-KG].
P.CSP_QCert
Qualified certificate
The CSP uses a trustworthy CGA to generate the qualified certificate for the SVD generated by the SSCD.
The qualified certificates contains at least the elements defined in Annex I of the Directive, i.e., inter alia the
name of the signatory and the SVD matching the SCD implemented in the TOE under sole control of the
signatory. The CSP ensures that the use of the TOE is evident with signatures through the certificate or other
publicly available information.
P.Qsign
Qualified electronic signatures
The signatory uses a signature-creation system to sign data with qualified electronic signatures. The DTBS
are presented to the signatory by the SCA. The qualified electronic signature is based on a qualified
certificate and is created by a SSCD.
P.Sigy_SSCD
TOE as secure signature-creation device
The TOE implements the SCD used for signature creation under sole control of the signatory. The SCD used
for signature generation can practically occur only once.

P.Pre-personalisation Strong authentication in pre-personalisation
During pre-personalisation, The TOE protects itself with strong authentication.
3.5 COMPATIBILITY BETWEEN SECURITY ENVIRONMENTS OF [ST-IAS] AND [ST-PLTF]
3.5.1 Compatibility between threats of [ST-IAS] and [ST-PLTF]
T.Hack_Phys and T.SCD_Divulg are included in T.Physical
T.SCD_Derive, T.Sig_Forgery, T.DTBS_Forgery, T.Sig_Repud, T.SVD_Forgery, and T.SigF_Misuse are
threats specific to [ST-IAS] and they do not conflict with the threats of [ST-PLTF].
We can therefore conclude that the threats of [ST-IAS] and [ST-PLTF] are consistent.
3.5.2 Compatibility between OSP of [ST-IAS] and [ST-PLTF]
P.CSP_QCert, P.Qsign, and P.Sigy_SSCD and P.Pre-personalisation are OSP specific to [ST-IAS] and they
do not conflict with the OSP of [ST-PLTF].
We can therefore conclude that the OSP of [ST-IAS] and [ST-PLTF] are consistent.
3.5.3 Compatibility between assumptions of [ST-IAS] and [ST-PLTF]
A.CGA, A.SCA, and A.SCD_Generate are assumptions specific to [ST-IAS] and they do no conflict with the
assumptions of [ST-PLTF].
We can therefore conclude that the assumptions of [ST-IAS] and [ST-PLTF] are consistent.
3.6 JUSTIFICATIONS FOR ADDING ASSUMPTIONS ON THE ENVIRONMENT
3.6.1.1 Additions to [PP-SSCD-KG]
The only additional assumption on the environment is A.SCD_Generate. This assumption deals with the
SCD generation when the SCD is generated off-TOE and imported afterwards. These two operations are
outside the scope of [PP-SSCD-KG]. Therefore the added assumption does not weaken the TOE.

Tamper detection
The TOE provides system features that detect physical tampering of a system component, and use those
features to limit security breaches.
OT.Tamper_Resistance
Tamper resistance
The TOE prevents or resists physical tampering with specified system devices and components.
OT.DTBS_Integrity_TOE
Verification of the DTBS-representation integrity
The TOE shall verify that the DTBS-representation received from the SCA has not been altered in transit
between the SCA and the TOE. The TOE itself shall ensure that the DTBS-representation is not altered by
the TOE as well. Note, that this does not conflict with the signature-creation process where the DTBS itself
could be hashed by the TOE.
OT.Sigy_SigF
Signature generation function for the legitimate signatory only

4.3.1 Threats
T.Hack_Phys (Exploitation of physical vulnerabilities) deals with physical attacks exploiting physical
vulnerabilities of the TOE. OT.SCD_Secrecy preserves the secrecy of the SCD.
OT.EMSEC_Design counters physical attacks through the TOE interfaces or observation of TOE
emanations. OT.Tamper_ID and OT.Tamper_Resistance counter the threat T.Hack_Phys by detecting
and by resisting tamper attacks.
T.SCD_Divulg (Storing and copying and releasing of the signature-creation data) addresses the threat
against the legal validity of electronic signature due to storage and copying of SCD outside the TOE, as
expressed in the Directive [1], recital (18). This threat is countered by OT.SCD_secrecy, which assures
the secrecy of the SCD used for signature generation.
OT.SCD_Transfer and OE.SCD_Transfer ensure the confidentiality of the SCD transferred between
SSCDs.
T.SCD_Derive (Derive the signature-creation data) deals with attacks on the SCD via public known data
produced by the TOE. This threat is countered by OE.SCD_Unique that provides cryptographic secure
generation of the SCD/SVD pair. OT.Sig_Secure ensures cryptographic secure electronic signatures.

T.Sig_Forgery (Forgery of the electronic signature) deals with non-detectable forgery of the electronic
signature. This threat is in general addressed by OT.Sig_Secure (Cryptographic security of the electronic
signature), OE.SCA_Data_Intend (SCA sends representation of data intended to be signed),
OE.CGA_QCert (Generation of qualified certificates), OT.SCD_SVD_Corresp (Correspondence between
SVD and SCD), OT.SVD_Auth_TOE (TOE ensures authenticity of the SVD), OE.SVD_Auth_CGA (CGA
proves the authenticity of the SVD), OT.SCD_Secrecy (Secrecy of the signature-creation data),
OT.SCD_Transfer (Secure transfer of SCD between SSCD), OT.EMSEC_Design (Provide physical
emanations security), OT.Tamper_ID (Tamper detection), OT.Tamper_Resistance (Tamper resistance)
and OT.Lifecycle_Security (Lifecycle security), as follows.
OT.Sig_Secure ensures by means of robust encryption techniques that the signed data and the electronic
signature are securely linked together. OE.SCA_Data_Intend provides that the methods used by the SCA
(and therefore by the verifier) for the generation of the DTBS-representation is appropriate for the
cryptographic methods employed to generate the electronic signature. The combination of
OE.CGA_QCert, OT.SCD_SVD_Corresp, OT.SVD_Auth_TOE, and OE.SVD_Auth_CGA provides the
integrity and authenticity of the SVD that is used by the signature verification process. OT.Sig_Secure,
OT.SCD_Secrecy, OT.SCD_Transfer, OT.EMSEC_Design, OT.Tamper_ID, OT.Tamper_Resistance, and
OT.Lifecycle_Security ensure the confidentiality of the SCD implemented in the signatory's SSCD and
thus prevent forgery of the electronic signature by means of knowledge of the SCD.
T.Sig_Repud (Repudiation of electronic signatures) deals with the repudiation of signed data by the
signatory, although the electronic signature is successfully verified with the SVD contained in his un-
revoked certificate. This threat is in general addressed by OE.CGA_QCert (Generation of qualified
certificates), OT.SVD_Auth_TOE (TOE ensures authenticity of the SVD), OE.SVD_Auth_CGA (CGA
proves the authenticity of the SVD), OT.SCD_SVD_Corresp (Correspondence between SVD and SCD),
OT.SCD_Unique (Uniqueness of the signature creation data), OT.SCD_Transfer (Secure transfer of SCD
between SSCD), OT.SCD_Secrecy (Secrecy of the signature-creation data), OT.EMSEC_Design
(Provide physical emanations security), OT.Tamper_ID (Tamper detection), OT.Tamper_Resistance
(Tamper resistance), OT.Lifecycle_Security (Lifecycle security), OT.Sigy_SigF (Signature generation
function for the legitimate signatory only), OT.Sig_Secure (Cryptographic security of the electronic
signature), OE.SCA_Data_Intend (SCA sends representation of data intended to be signed) and
OT.DTBS_Integrity_TOE (Verification of the DTBS-representation integrity).
OE.CGA_QCert ensures qualified certificates which allow to identify the signatory and thus to extract the
SVD of the signatory. OE.CGA_QCert, OT.SVD_Auth_TOE and OE.SVD_Auth_CGA ensure the integrity
of the SVD. OE.CGA_QCert and OT.SCD_SVD_Corresp ensure that the SVD in the certificate
correspond to the SCD that is implemented by the SSCD of the signatory. OT.SCD_Unique provides that
the signatory's SCD can practically occur just once. OT.Sig_Secure, OT.SCD_Transfer,
OT.SCD_Secrecy, OT.Tamper_ID, OT.Tamper_Resistance, OT.EMSEC_Design, and
OT.Lifecycle_Security ensure the confidentiality of the SCD implemented in the signatory's SSCD.
OT.Sigy_SigF provides that only the signatory may use the TOE for signature generation. OT.Sig_Secure
ensures by means of robust cryptographic techniques that valid electronic signatures may only be
generated by employing the SCD corresponding to the SVD that is used for signature verification and
only for the signed data. OE.SCA_Data_Intend and OT.DTBS_Integrity_TOE ensure that the TOE
generates electronic signatures only for DTBS-representations that the signatory has decided to sign.
T.SVD_Forgery (Forgery of the signature-verification data) deals with the forgery of the SVD exported by
the TOE to the CGA for the generation of the certificate. T.SVD_Forgery is addressed by
OT.SVD_Auth_TOE, which ensures that the TOE sends the SVD in a verifiable form to the CGA, as well
as by OE.SVD_Auth_CGA, which provides verification of SVD authenticity by the CGA.
T.DTBS_Forgery (Forgery of the DTBS-representation) addresses the threat arising from modifications of
the DTBS-representation sent to the TOE for signing which then does not correspond to the DTBS-

the means of OT.DTBS_Integrity_TOE by verifying the integrity of the DTBS-representation. The TOE IT
environment addresses T.DTBS_Forgery by the means of OE.SCA_Data_Intend.
T.SigF_Misuse (Misuse of the signature-creation function of the TOE) addresses the threat of misuse of
the TOE signature-creation function to create SDO by others than the signatory to create SDO for data
the signatory has not decided to sign, as required by the Directive [1], Annex III, paragraph 1, literal (c).
This threat is addressed by the OT.Sigy_SigF (Signature generation function for the legitimate signatory
only), OE.SCA_Data_Intend (Data intended to be signed), OT.DTBS_Integrity_TOE (Verification of the
DTBS-representation integrity), and OE.HI_VAD (Protection of the VAD) as follows:
OT.Sigy_SigF ensures that the TOE provides the signature-generation function for the legitimate
signatory only. OE.SCA_Data_Intend ensures that the SCA sends the DTBS-representation only for data
the signatory intends to sign. The combination of OT.DTBS_Integrity_TOE and OE.SCA_Data_Intend
counters the misuse of the signature generation function by means of manipulation of the channel
between the SCA and the TOE. If the SCA provides the human interface for the user authentication,
OE.HI_VAD provides confidentiality and integrity of the VAD as needed by the authentication method
employed.
4.3.2 Assumptions
A.CGA (Trustworthy certification-generation application) establishes the protection of the authenticity of
the signatory's name and the SVD in the qualified certificate by the advanced signature of the CSP by
means of the CGA. This is addressed by OE.CGA_QCert (Generation of qualified certificates), which
ensures the generation of qualified certificates, and by OE.SVD_Auth_CGA (CGA proves the authenticity
of the SVD), which ensures the verification of the integrity of the received SVD and the correspondence
between the SVD and the SCD that is implemented by the SSCD of the signatory.
A.SCA (Trustworthy signature-creation application) establishes the trustworthiness of the SCA according
to the generation of DTBS-representation. This is addressed by OE.SCA_Data_Intend (Data intended to
be signed) which ensures that the SCA generates the DTBS-representation of the data that has been
presented to the signatory as DTBS and which the signatory intends to sign in a form which is appropriate
for being signed by the TOE.
A.SCD_Generate Trustworthy SCD/SVD generation establishes a trustworthy SCD/SVD pair. This means
that the SCD must be unique, objective met by OE.SCD_Unique, that the SCD and the SVD must
correspond, objective met by OE.SCD_SVD_Corresp. The secrecy of the SCD must be maintained while
it is transferred to the TOE before being deleted, OE.SCD_Transfer.
4.3.3 Organisational security policies
P.CSP_QCert (CSP generates qualified certificates) establishes the qualified certificate for the signatory
and provides that the SVD matches the SCD that is implemented in the SSCD under sole control of this
signatory. On SCD/SVD correspondence, this OSP is addressed by OT.SCD_SVD_Corresp and
OE.SCD_SVD_Corresp. In the IT environment, this OSP is addressed by OE.CGA_QCert for generation
of qualified certificates by the CGA, respectively.
P.QSign (Qualified electronic signatures) provides that the TOE and the SCA may be employed to sign
data with qualified electronic signatures, as defined by the Directive [1], article 5, paragraph 1. Directive
[1], recital (15) refers to SSCDs to ensure the functionality of advanced signatures. The requirement of
qualified electronic signatures being based on qualified certificates is addressed by OE.CGA_QCert.

OE.SCA_Data_Intend ensures that the SCA presents the DTBS to the signatory and sends the DTBS-
representation to the TOE. OT.Sig_Secure and OT.Sigy_SigF address the generation of advanced
signatures by the TOE.
P.Sigy_SSCD (TOE as secure signature-creation device) establishes the TOE as secure signature-
creation device of the signatory with practically unique SCD. This OSP is addressed by OT.Sigy_SigF
that ensures that the SCD is under sole control of the signatory, and OE.SCD_Unique that ensures that
the cryptographic quality of the SCD/SVD pair for the qualified electronic signature.
Additionally, for the SSCD Type 3: OT.Init ensures that generation of the SCD/SVD pair is restricted to
authorised users.
P.Pre-personalisation (Strong authentication in pre-personalisation) requests a strong authentication
before accessing the SSCD. This is directly addressed by OT.Pre-personalisation.
4.3.4 Compatibility between objectives of [ST-IAS] and [ST-PLTF]
4.3.4.1 Compatibility between objectives for the TOE
OT.EMSEC_Design, OT.Lifecycle_Security, OT.SCD_Secrecy, OT.Tamper_ID, OT.Tamper_Resistance,
and OT.DTBS_Integrity_TOE deal with physical protection of the TOE. These are supported by. O.SCP.IC.
OT.SCD_SVD_Corresp, OT.SVD_Auth_TOE, OT.SCD_Transfer, OT.Init, OT.SCD_Unique, and OT.Pre-
personalisation are objectives specific to [ST-IAS] and they do no conflict with the objectives of [ST-PLTF].
We can therefore conclude that the objectives for the TOE of [ST-IAS] and [ST-PLTF] are consistent.
4.3.4.2 Compatibility between objectives for the environment
OE.CGA_QCert, OE.SVD_Auth_CGA, OE.HI_VAD, OE.SCA_Data_Intend, OE.SCD_SVD_Corresp,
OE.SCD_Transfer, and OE.SCD_Unique are objectives specific to [ST-IAS] and they do no conflict with the
objectives of [ST-PLTF].
We can therefore conclude that the objectives for the environment of [ST-IAS] and [ST-PLTF] are consistent.
4.3.5 Justifications for adding objectives on the environment
4.3.5.1 Additions to [PP-SSCD-KG]
The only additional objectives on the environment are: OE.SCD_SVD_Corresp, OE.SCD_Transfer,
OE_SCD_Unique. These objectives request the environment to perform several operations when the SCD is
generated off-TOE and imported afterwards. These two operations are outside the scope of [PP-SSCD-KG].
Therefore the added objectives on the environment do not weaken the TOE.

5. EXTENDED COMPONENTS DEFINITION
This ST uses one component defined as extensions to CC part 2: FPT_EMS.1 which is defined as
FPT_EMSEC.1 in protection profile [PP-SSCD-KI] and [PP-SSCD-KG].
The additional family FPT_EMS (TOE Emanation) of the Class FPT (Protection of the TSF) is defined here to
describe the IT security functional requirements of the TOE. The TOE shall prevent attacks against the TOE
and other secret data where the attack is based on external observable physical phenomena of the TOE.
Examples of such attacks are evaluation of TOE’s electromagnetic radiation, simple power analysis (SPA),
differential power analysis (DPA), timing attacks, etc. This family describes the functional requirements for
the limitation of intelligible emanations which are not directly addressed by any other component of CC part 2
[CC-2].
The family “TOE Emanation (FPT_EMS)” is specified as follows.
Family behavior
This family defines requirements to mitigate intelligible emanations.
Component levelling:

Table 13: Objective vs SFR rationale
OT.EMSEC_Design (Provide physical emanations security) covers that no intelligible information is
emanated. This is provided by FPT_EMS.1.
OT.Lifecycle_Security The test function FPT_TST.1 provides failure detection throughout the lifecycle.
FCS_CKM.4/SCD provides secure destruction of the SCD to conclude the operational usage of the TOE
as SSCD.
OT.SCD_Secrecy (Secrecy of signature-creation data) counters that, with reference to recital (18) of the
Directive, storage or copying of SCD causes a threat to the legal validity of electronic signatures. The
authentication and access management functions specified by FMT_MOF.1, FMT_MSA.1/AdminKG,
FMT_MSA.1/AdminKI, FMT_MSA.3, FMT_MSA.4, and FMT_SMR.1 ensure that only the signatory can
use the SCD and thus avoid that an attacker may gain information on it. OT.SCD_Secrecy is provided [for
a Type 3 SSCD] by the security functions specified by FDP_ACC.1/Initialisation SFP and
FDP_ACF.1/Initialisation SFP that ensure that only authorised user can initialise the TOE and create or
load the SCD.
FCS_CKM.1/SCD ensures the generation of SCD on board.
The security functions specified by FDP_RIP.1 and FCS_CKM.4/SCD ensure that residual information on
SCD is destroyed after the SCD has been used for signature creation and that destruction of SCD leaves
no residual information. Cryptographic quality of SCD/SVD pair shall prevent disclosure of SCD by
cryptographic attacks using the publicly known SVD.
The security functions specified by FDP_SDI.2/Persistent ensure that no critical data is modified which
could alter the efficiency of the security functions or leak information of the SCD. FPT_FLS.1 tests the
working conditions of the TOE and guarantees a secure state when integrity is violated and thus assures
that the specified security functions are operational. An example where compromising error conditions are
countered by FPT_FLS is differential fault analysis (DFA).
OT.SCD_SVD_Corresp (Correspondence between SVD and SCD) addresses that the SVD corresponds to
the SCD implemented by the TOE. The security functions specified by FDP_SDI.2/Persistent ensure that
the keys are not modified, so to retain the correspondence. Cryptographic correspondence is provided by
FCS_COP.1/CORRESP. Additionally, for a Type 3 SSCD: This is provided by the algorithms specified by
FCS_CKM.1/SCD to generate corresponding SVD/SCD pairs.
OT.SVD_Auth_TOE (TOE ensures authenticity of the SVD) is provided by a trusted channel guaranteeing
SVD origin and integrity by means of FTP_ITC.1/SVD Transfer and FDP_UIT.1/SVD Transfer. The
cryptographic algorithms specified by FDP_ACC.1/SVD Transfer SFP and FDP_ACF.1/SVD Transfer
SFP ensure that only authorised user can Import the SVD from a SSCD Type1 and Export the SVD to the
CGA.
FCS_CKM.1/Session ensures the generation of session keys. FCS_CKM.4/Session ensures their
destruction. FCS_COP.1/Session ensures the integrity of data transmitted through the secure channel.
OT.Tamper_ID (Tamper detection) is provided by FPT_PHP.1 by the means of passive detection of physical
attacks.
OT.Tamper_Resistance (Tamper resistance) is provided by FPT_PHP.3 to resist physical attacks.

OT.DTBS_Integrity_TOE (Verification of DTBS-representation integrity) covers that integrity of the DTBS-
representation to be signed is to be verified, as well as the DTBS-representation is not altered by the
TOE. This is provided by the trusted channel integrity verification mechanisms of FDP_ITC.1/DTBS,
FTP_ITC.1/DTBS Import and by FDP_UIT.1/TOE DTBS. The verification that the DTBS-representation
has not been altered by the TOE is done by integrity functions specified by FDP_SDI.2/DTBS. The
access control requirements of FDP_ACC.1/Signature-creation SFP and FDP_ACF.1/Signature-creation
SFP keeps unauthorised parties off from altering the DTBS-representation.
FCS_CKM.1/Session ensures the generation of session keys. FCS_CKM.4/Session ensures their
destruction. FCS_COP.1/Session ensures the integrity of DTBS transmitted through the secure channel.
OT.Sigy_SigF (Signature generation function for the legitimate signatory only) is provided by FIA_UAU.1
and FIA_UID.1 that ensure that no signature generation function can be invoked before the signatory is
identified and authenticated.
The security functions specified by FDP_ACC.1/Personalisation SFP, FDP_ACC.1/Signature-creation
SFP, FDP_ACF.1/Personalisation SFP, FDP_ACF.1/Signature-creation SFP, FMT_MTD.1 and
FMT_SMR.1 ensure that the signature process is restricted to the signatory.
The security functions specified by FIA_ATD.1, FMT_MOF.1, FMT_MSA.2, FMT_MSA.3, and
FMT_MSA.4 ensure that the access to the signature generation functions remain under the sole control of
the signatory, as well as FMT_MSA.1/Signatory provides that the control of corresponding security
attributes is under signatory's control.
The security functions specified by FDP_SDI.2/Persistent and FPT_TRP.1/TOE ensure the integrity of
stored data both during communication and while stored.
The security functions specified by FDP_RIP.1 and FIA_AFL.1 provide protection against a number of
attacks, such as cryptographic extraction of residual information, or brute force attacks against
authentication.
OT.Sig_Secure (Cryptographic security of the electronic signature) is provided by the cryptographic
algorithms specified by FCS_COP.1/DSC which ensures the cryptographic robustness of the signature
algorithms. The security function specified by FPT_TST.1 ensures that the security functions are
performing correctly. FDP_SDI.2/Persistent corresponds to the integrity of the SCD implemented by the
TOE.
SSCD Type 2 only
OT.SCD_Transfer (Secure transfer of SCD between SSCD) is provided by FDP_ITC.1/SCD Import and
FDP_UCT.1/Receiver that ensure that a trusted channel is provided and that confidentiality is maintained.
Security functions specified by FDP_ACC.1/SCD Import SFP, FMT_MSA.2, FMT_MSA.3//KeyImport,
FMT_SMR.1 and FDP_ACF.1/SCD Import SFP ensure that transfer of SCDs is restricted to
administrators. This supports the confidentiality-oriented functions.
Security function FCS_CKM.4/SCD destroys the SCD before a SCD is re-imported into the TOE.
FCS_CKM.1/Session ensures the generation of session keys. FCS_CKM.4/Session ensures their
destruction. FCS_COP.1/Session ensures the integrity of DTBS transmitted through the secure channel.
SSCD Type 3 only
OT.SCD_Unique (Uniqueness of the signature-creation data) stores the requirement of practically unique
SCD as laid down in the Directive [1], Annex III, article 1(a), which is provided by the cryptographic
algorithms specified by FCS_CKM.1/SCD.
OT.Init It addresses that generation of a SCD/SVD pair requires proper user authentication. FIA_ATD.1
defines RAD as the corresponding user attribute. The TSF specified by FIA_UID.1 and FIA_UAU.1
provide user identification and user authentication prior to enabling access to authorised functions. The
attributes of the authenticated user are provided by FMT_MSA.1/AdminKG, FMT_MSA.1/AdminKI,

6.3.3 Security Assurance Requirements Rationale
EAL5 was chosen because it provides a high level of independently assured security in a planned
development. It requires a rigorous development approach without incurring unreasonable costs attributable
to specialist security engineering techniques.
The selection of the component ALC_DVS.2 provides a higher assurance of the security of the SSCD’s
development and manufacturing especially for the secure handling of the SSCD’s material.
The selection of the component AVA_VAN.5 provides a higher assurance of the security by vulnerability
analysis to assess the resistance to penetration attacks performed by an attacker possessing a high attack
potential.
6.3.4 Compatibility between SFR of [ST-IAS] and [ST-PLTF]
FCS_CKM.1 and FCS_COP.1 of [ST-IAS] are supported by FCS_CKM.1 and FCS_COP.1 of [ST-PLTF].
FDP_SDI.2 of [ST-IAS] is supported by FDP_SDI.2 of [ST-PLTF].
FPT_PHP.3 of [ST-IAS] is supported by FPT_PHP.3 of [ST-PLTF].
FPT_EMS.1, FPT_FLS.1, FPT_TST.1, FPT_PHP.1 and FPT_PHP.3 of [ST-IAS] are supported by
FPT_TST.1 of [ST-PLTF].
FCS_CKM.4, FDP_ACC.1, FDP_ACF.1, FDP_ETC.1, FDP_ITC.1, FDP_RIP.1, FDP_UCT.1, FDP_UIT.1,
FIA_AFL.1, FIA_ATD.1, FIA_UAU.1, FIA_UID.1, FMT_MOF.1, FMT_MSA.1, FMT_MSA.2, FMT_MSA.3,
FMT_MTD.1, FMT_SMF.1, FMT_SMR.1, FPT_EMS.1, FTP_ITC.1, and FTP_TRP.1 are SFR specific to the
IAS application and they do no conflict with the SFR of [ST-PLTF].
We can therefore conclude that the SFR of [ST-IAS] and [ST-PLTF] are consistent.
