TOE OVERVIEW
1
The MultiApp ID V2.1 product is a smartcard addressing the identity market. Built upon an opened javacard
platform, the smartcard application software implements identification, authentication and signature (IAS)
services, as well as secure data storage and biometry features.
These services are enabled through the personalization of one or several corresponding applets:
-
IAS XL: digital signature application compatible with IAS ECC v1.01 specification defined by
Gixel (French smartcard industry association)
-
IAS Classic V3: digital signature application with RSA up to 2048 and SHA256
-
MPCOS: secure data storage 3DES based and PIN protection
-
MOCA server: offers a match on card services to applications
-
MOCA client: match on card application using MOCA server
-
Crypto Manager: additional Match on Card application from Precise Biometrics Company.
The MultiApp ID V2.1 product is a “contact-only” smartcard compliant with [ISO7816], and supporting T=0
and T=1 communication protocols.
1
The Java Card technology combines a subset of the Java programming language with a runtime environment optimized for smart
cards and similar small-memory embedded devices [JCVM222]. The Java Card platform is a smart card platform enabled with Java
Card technology (also called a “Java card”). This technology allows for multiple applications to run on a single card and provides
facilities for secure interoperability of applications. Applications for the Java Card platform (“Java Card applications”) are called applets.

MultiApp ID V2.1 – JCS Security Target
For the present ST, the Target of Evaluation (TOE) is the JCS part of the MultiApp ID V2.1 smartcard
software. The TOE boundaries encompass:
The MultiApp ID V2.1 javacard platform software, which supports the execution of the
personalized applets and provides card administration services.
The data owned by the MultiApp ID V2.1 javacard platform (smartcard-related data)
The Integrated Circuit (either P5CC081 or P5CC145)
The guidance documentation [AGD]
This TOE provides the security of an EAL5+ evaluated card with the flexibility of an open platform. It allows
for the loading of applets before or after the issuance of the card. These applets MAY or MAY NOT be
evaluated on this platform.
The applications using only certified applets will BE certified even if NOT-certified applets are loaded on the
platform. The applications using a NOT-certified applet will NOT BE certified.
The Issuer can forbid the loading of applets before or after the issuance of the card.

4 TOE DESCRIPTION
4.1
ARCHITECTURE OF THE SMARTCARD CONTAINING THE TOE
The TOE is part of the MultiApp ID V2.1 smartcard. This smartcard contains the software dedicated to the
operation of:
The MultiApp ID V2.1 javacard platform, which supports the execution of the personalized
applets and provides the smartcard administration services.
The identity applets: IAS XL, IAS Classic V3, MPCOS 4.1, MOCA Server 1.0, MOCA Client
1.0, and Crypto Manager.
Additionally, as mentioned in section 3.3, other applets – not determined at the moment of the
present evaluation – may be loaded on the smartcard before or after issuance.
Therefore, the architecture of the smartcard software and application data can be represented as follows:
Figure 1: MultiApp ID V2.1 smartcard architecture

MultiApp ID V2.1 – JCS Security Target
2
Actually, the IAS XL & Classic V3 functionalities , as well as the MPCOS 4.1 functionality, the MOCA
Server/Client functionalities and the MultiApp V2.1 javacard platform, are located in ROM. The Crypto
Manager functionality is located in EEPROM, and any additional applet’s executable code (loaded before or
after issuance) would also be located in EEPROM, which might also contain any software patch that would be
needed in the future.
All the data (related to the applets or to the javacard platform) are located in EEPROM. The separation
between these data is ensured by the javacard firewall as specified in [JCRE222].

End-usage
The SC issuer is responsible for the SC product delivery to
the SC end-user (cardholder), and the end of life process.
The cardholder is a
customer of the SC
issuer.
Table 1: MultiApp ID V2.1 product life-cycle
Two scenarios are to be considered for the present evaluation:
-
The first scenario (LC1), which is the standard one, is described by figure 4.
According to this scenario, the IC is manufactured at NXP site. It is then shipped to
Gemalto site where it is initialized and pre-personalized and then shipped to the
Personalizer. During the shipment from Gemalto to the Personalizer, the module is
protected by a diversified key.
-
The second scenario (LC2) is an alternative to LC1, and is described by figure 5. It
corresponds to the situation where the customer whishes to receive wafers directly
from the founder. In this case, initialization and pre-personalization, which include
sensitive operations such as the loading of patches, take place at NXP site. The
creation of files is started by the founder and completed by the personalizer. During
the shipment from NXP to the Personalizer, the module is protected by a diversified
key.

4.4.2 TOE life-cycle
The javacard system (i.e. the TOE) life-cycle itself can be decomposed in four stages:
-
Development
-
Storage, pre-personalization and testing
-
Personalization and testing
-
Final usage
The JCS storage is not necessarily a single step in the life cycle since it can be stored in parts. The JCS
delivery occurs before storage and may take place more than once if the TOE is delivered in parts.
These four stages map to the product life cycle phases as shown in Figure 6.
Figure 6: JCS (TOE) Life Cycle within Product Life Cycle
JCS Development is performed during Phase 1. This includes JCS conception, design, implementation,
testing and documentation. The JCS development shall fulfill requirements of the final product, including
conformance to Java Card Specifications, and recommendations of the SCP user guidance. The JCS
development shall occur in a controlled environment that avoids disclosure of source code, data and any
critical documentation and that guarantees the integrity of these elements. The present evaluation includes
the JCS development environment.
In Phase 3, the IC Manufacturer may store, initialize the JCS and potentially conduct tests on behalf of the
JCS developer. The IC Manufacturing environment shall protect the integrity and confidentiality of the JCS
and of any related material, for instance test suites. The present evaluation includes the whole IC
Manufacturing environment, in particular those locations where the JCS is accessible for installation or

testing. As the Security IC has already been certified against [PP/0035] there is no need to perform the
evaluation again.
In Phase 5, the SC Pre-Personalizer may store, pre-personalize the JCS and potentially conduct tests on
behalf of the JCS developer. The SC Pre-Personalization environment shall protect the integrity and
confidentiality of the JCS and of any related material, for instance test suites.
(Part of) JCS storage in Phase 5 implies a TOE delivery after Phase 5. Hence, the present evaluation
includes the SC Pre-Personalization environment. The TOE delivery point is placed at the end of Phase 5,
since the entire TOE is then built and embedded in the Security IC.
The JCS is personalized in Phase 6, if necessary. The SC Personalization environment is not included in the
present evaluation. Appropriate security recommendations are provided to the SC Personalizer through the
[AGD] documentation.
The JCS final usage environment is that of the product where the JCS is embedded in. It covers a wide
spectrum of situations that cannot be covered by evaluations. The JCS and the product shall provide the full
set of security functionalities to avoid abuse of the product by untrusted entities.

6 SECURITY ASPECTS
This chapter describes the main security issues of the Java Card System and its environment addressed in
this ST, called “security aspects”, in a CC-independent way. In addition to this, they also give a semi-formal
framework to express the CC security environment and objectives of the TOE. They can be instantiated as
assumptions, threats, objectives (for the TOE and the environment) or organizational security policies. For
instance, we will define hereafter the following aspect:
#.OPERATE (1) The TOE must ensure continued correct operation of its security functions.
(2) The TOE must also return to a well-defined valid state before a service request in case of
failure during its operation.
TSFs must be continuously active in one way or another; this is called “OPERATE”.
6.1
CONFIDENTIALITY
#.CONFID-APPLI-DATA
Application data must be protected against unauthorized disclosure. This
concerns logical attacks at runtime in order to gain read access to other
application’s data.
#.CONFID-JCS-CODE
Java Card System code must be protected against unauthorized disclosure.
Knowledge of the Java Card System code may allow bypassing the TSF. This
concerns logical attacks at runtime in order to gain a read access to executable
code, typically by executing an application that tries to read the memory area
where a piece of Java Card System code is stored.
#.CONFID-JCS-DATA
Java Card System data must be protected against unauthorized disclosure. This
concerns logical attacks at runtime in order to gain a read access to Java Card
System data. Java Card System data includes the data managed by the Java
Card RE, the Java Card VM and the internal data of Java Card platform API
classes as well.
6.2
INTEGRITY
#.INTEG-APPLI-CODE
Application code must be protected against unauthorized modification. This
concerns logical attacks at runtime in order to gain write access to the memory
zone where executable code is stored. In post-issuance application loading, this
threat also concerns the modification of application code in transit to the card.
#.INTEG-APPLI-DATA
Application data must be protected against unauthorized modification. This
concerns logical attacks at runtime in order to gain unauthorized write access to
application data. In post-issuance application loading, this threat also concerns the
modification of application data contained in a package in transit to the card. For
instance, a package contains the values to be used for initializing the static fields
of the package.
#.INTEG-JCS-CODE
Java Card System code must be protected against unauthorized modification.
This concerns logical attacks at runtime in order to gain write access to
executable code.

Java Card System data must be protected against unauthorized modification. This
concerns logical attacks at runtime in order to gain write access to Java Card
System data. Java Card System data includes the data managed by the Java

well.

UNAUTHORIZED EXECUTIONS
#.EXE-APPLI-CODE
#.EXE-JCS-CODE
#.FIREWALL
#.NATIVE
6.4
Application (byte)code must be protected against unauthorized execution. This
concerns (1) invoking a method outside the scope of the accessibility rules provided
by the access modifiers of the Java programming language ([JAVASPEC]§6.6); (2)
jumping inside a method fragment or interpreting the contents of a data memory
area as if it was executable code; (3) unauthorized execution of a remote method
from the CAD.
Java Card System bytecode must be protected against unauthorized execution. Java
Card System bytecode includes any code of the Java Card RE or API. This concerns
(1) invoking a method outside the scope of the accessibility rules provided by the
access modifiers of the Java programming language ([JAVASPEC]§6.6); (2) jumping
inside a method fragment or interpreting the contents of a data memory area as if it
was executable code. Note that execute access to native code of the Java Card
System and applications is the concern of #.NATIVE.
The Firewall shall ensure controlled sharing of class instances, and isolation of their data
and code between packages (that is, controlled execution contexts) as well as between
packages and the JCRE context. An applet shall neither read, write nor compare a piece of
data belonging to an applet that is not in the same context, nor execute one of the methods
of an applet in another context without its authorization.
Because the execution of native code is outside of the JCS TSF scope, it must be secured
so as to not provide ways to bypass the TSFs of the JCS. Loading of native code, which is as
well outside the TSFs, is submitted to the same requirements. Should native software be
privileged in this respect, exceptions to the policies must include a rationale for the new
security framework they introduce.
BYTECODE VERIFICATION
#.VERIFICATION
All bytecode must be verified prior to being executed. Bytecode verification includes
(1) how well-formed CAP file is and the verification of the typing constraints on the
bytecode, (2) binary compatibility with installed CAP files and the assurance that the
export files used to check the CAP file correspond to those that will be present on the
card when loading occurs.
6.4.1 CAP FILE VERIFICATION
Bytecode verification includes checking at least the following properties: (1) bytecode instructions represent a
legal set of instructions used on the Java Card platform; (2) adequacy of bytecode operands to bytecode
semantics; (3) absence of operand stack overflow/underflow; (4) control flow confinement to the current
method (that is, no control jumps to outside the method); (5) absence of illegal data conversion and reference
forging; (6) enforcement of the private/public access modifiers for class and class members; (7) validity of
any kind of reference used in the bytecodes (that is, any pointer to a bytecode, class, method, object, local
variable, etc actually points to the beginning of piece of data of the expected kind); (8) enforcement of rules
for binary compatibility (full details are given in [JCVM222], [JVM], [JCBV]). The actual set of checks
performed by the verifier is implementation-dependent, but shall at least enforce all the “must clauses”
imposed in [JCVM222] on the bytecodes and the correctness of the CAP files’ format.
As most of the actual Java Card VMs do not perform all the required checks at runtime, mainly because
smart cards lack memory and CPU resources, CAP file verification prior to execution is mandatory. On the
other hand, there is no requirement on the precise moment when the verification shall actually take place, as
far as it can be ensured that the verified file is not modified thereafter. Therefore, the bytecodes can be
verified either before the loading of the file on to the card or before the installation of the file in the card or
Copyright Gemalto SA – 2012.
Page: 24/71
MultiApp ID V2.1 – JCS Security Target
before the execution, depending on the card capabilities, in order to ensure that each bytecode is valid at
execution time. This Security Target assumes bytecode verification is performed off-card.
Another important aspect to be considered about bytecode verification and application downloading is, first,
the assurance that every package required by the loaded applet is indeed on the card, in a binary-compatible
version (binary compatibility is explained in [JCVM222] §4.4), second, that the export files used to check and
link the loaded applet have the corresponding correct counterpart on the card.
6.4.2 INTEGRITY AND AUTHENTICATION
Verification off-card is useless if the application package is modified afterwards. The usage of cryptographic
certifications coupled with the verifier in a secure module is a simple means to prevent any attempt of
modification between package verification and package installation.
Once a verification authority has verified the package, it signs it and sends it to the card. Prior to the
installation of the package, the card verifies the signature of the package, which authenticates the fact that it
has been successfully verified. In addition to this, a secured communication channel is used to communicate
it to the card, ensuring that no modification has been performed on it.
Alternatively, the card itself may include a verifier and perform the checks prior to the effective installation of
the applet or provide means for the bytecodes to be verified dynamically. On-card bytecode verifier is out of
the scope of this Security Target.
6.4.3 LINKING AND VERIFICATION
Beyond functional issues, the installer ensures at least a property that matters for security: the loading order
shall guarantee that each newly loaded package references only packages that have been already loaded on
the card. The linker can ensure this property because the Java Card platform does not support dynamic
downloading of classes.
6.5
CARD MANAGEMENT
#.CARD-MANAGEMENT
#.INSTALL
#.SID
(1) The card manager (CM) shall control the access to card management
functions such as the installation, update or deletion of applets. (2) The card
manager shall implement the card issuer’s policy on the card.
(1) The TOE must be able to return to a safe and consistent state should the installation of a
package or an applet fail or be cancelled (whatever the reasons). (2) Installing an applet
must have no effect on the code and data of already installed applets. The installation
procedure should not be used to bypass the TSFs. In short, it is an atomic operation, free of
harmful effects on the state of the other applets. (3) The procedure of loading and installing a
package shall ensure its integrity and authenticity.
(1) Users and subjects of the TOE must be identified. (2) The identity of sensitive users and
subjects associated with administrative and privileged roles must be particularly protected; this
concerns the Java Card RE, the applets registered on the card, and especially the default
applet and the currently selected applet (and all other active applets in Java Card System 2.2).
A change of identity, especially standing for an administrative role (like an applet impersonating
the Java Card RE), is a severe violation of the Security Functional Requirements (SFR).
Selection controls the access to any data exchange between the TOE and the CAD and
therefore, must be protected as well. The loading of a package or any exchange of data through
the APDU buffer (which can be accessed by any applet) can lead to disclosure of keys,
application code or data, and so on.
#OBJ-DELETION
(1) Deallocation of objects should not introduce security holes in the form of references
pointing to memory zones that are not longer in use, or have been reused for other
purposes. Deletion of collection of objects should not be maliciously used to circumvent
the TSFs. (2) Erasure, if deemed successful, shall ensure that the deleted class
instance is no longer accessible.
Copyright Gemalto SA – 2012.
Page: 25/71
MultiApp ID V2.1 – JCS Security Target
#DELETION
6.6
(1) Deletion of installed applets (or packages) should not introduce security holes in the form
of broken references to garbage collected code or data, nor should they alter integrity or
confidentiality of remaining applets. The deletion procedure should not be maliciously used to
bypass the TSFs. (2) Erasure, if deemed successful, shall ensure that any data owned by the
deleted applet is no longer accessible (shared objects shall either prevent deletion or be
made inaccessible). A deleted applet cannot be selected or receive APDU commands.
Package deletion shall make the code of the package no longer available for execution. (3)
Power failure or other failures during the process shall be taken into account in the
implementation so as to preserve the SFRs. This does not mandate, however, the process to
be atomic. For instance, an interrupted deletion may result in the loss of user data, as long as
it does not violate the SFRs.
The deletion procedure and its characteristics (whether deletion is either physical or logical,
what happens if the deleted application was the default applet, the order to be observed on
the deletion steps) are implementation-dependent. The only commitment is that deletion shall
not jeopardize the TOE (or its assets) in case of failure (such as power shortage).
Deletion of a single applet instance and deletion of a whole package are functionally different
operations and may obey different security rules. For instance, specific packages can be
declared to be undeletable (for instance, the Java Card API packages), or the dependency
between installed packages may forbid the deletion (like a package using super classes or
super interfaces declared in another package).
SERVICES
#.ALARM
The TOE shall provide appropriate feedback upon detection of a potential security violation.
This particularly concerns the type errors detected by the bytecode verifier, the security
exceptions thrown by the Java Card VM, or any other security-related event occurring during
the execution of a TSF.
#.OPERATE
(1) The TOE must ensure continued correct operation of its security functions. (2) In case of
failure during its operation, the TOE must also return to a well-defined valid state before the
next service request.
#.RESOURCES
#.CIPHER
The TOE controls the availability of resources for the applications and enforces quotas
and limitations in order to prevent unauthorized denial of service or malfunction of the
TSFs. This concerns both execution (dynamic memory allocation) and installation
(static memory allocation) of applications and packages.
The TOE shall provide a means to the applications for ciphering sensitive data, for instance,
through a programming interface to low-level, highly secure cryptographic services. In
particular, those services must support cryptographic algorithms consistent with cryptographic
usage policies and standards.
#.KEY-MNGT
The TOE shall provide a means to securely manage cryptographic keys. This includes: (1)
Keys shall be generated in accordance with specified cryptographic key generation
algorithms and specified cryptographic key sizes, (2) Keys must be distributed in
accordance with specified cryptographic key distribution methods, (3) Keys must be
initialized before being used, (4) Keys shall be destroyed in accordance with specified
cryptographic key destruction methods.
#.PIN-MNGT
The TOE shall provide a means to securely manage PIN objects. This includes: (1) Atomic
update of PIN value and try counter, (2) No rollback on the PIN-checking function, (3)
Keeping the PIN value (once initialized) secret (for instance, no clear-PIN-reading function),
(4) Enhanced protection of PIN’s security attributes (state, try counter…) in confidentiality
and integrity.
#.SCP
The smart card platform must be secure with respect to the SFRs. Then: (1) After a power loss or
sudden card removal prior to completion of some communication protocol, the SCP will allow the
Copyright Gemalto SA – 2012.
Page: 26/71
MultiApp ID V2.1 – JCS Security Target
TOE on the next power up to either complete the interrupted operation or revert to a secure state.
(2) It does not allow the SFRs to be bypassed or altered and does not allow access to other lowlevel functions than those made available by the packages of the API. That includes the protection
of its private data and code (against disclosure or modification) from the Java Card System. (3) It
provides secure low-level cryptographic processing to the Java Card System. (4) It supports the
needs for any update to a single persistent object or class field to be atomic, and possibly a lowlevel transaction mechanism. (5) It allows the Java Card System to store data in “persistent
technology memory” or in volatile memory, depending on its needs (for instance, transient objects
must not be stored in non-volatile memory). The memory model is structured and allows for low–
level control accesses (segmentation fault detection). (6) It safely transmits low–level exceptions to
the TOE (arithmetic exceptions, checksum errors), when applicable. We finally require that (7) the
IC is designed in accordance with a well defined set of policies and standards (for instance, those
specified in [PP-IC-0035]), and will be tamper resistant to actually prevent an attacker from
extracting or altering security data (like cryptographic keys) by using commonly employed
techniques (physical probing and sophisticated analysis of the chip). This especially matters to the
management (storage and operation) of cryptographic keys.
#.TRANSACTION
The TOE must provide a means to execute a set of operations atomically. This
mechanism must not endanger the execution of the user applications. The transaction
status at the beginning of an applet session must be closed (no pending updates).

7 SECURITY PROBLEM DEFINITION
7.1
ASSETS
The assets of the TOE are those defined in [PP-JCS-Open]. The assets of [PP/0035] are studied in [STP5CC081] and [ST-P5CC145].
Assets are security-relevant elements to be directly protected by the TOE. Confidentiality of assets is always
intended with respect to un-trusted people or software, as various parties are involved during the first stages
of the smart card product life-cycle; details are given in threats hereafter.
Assets may overlap, in the sense that distinct assets may refer (partially or wholly) to the same piece of
information or data. For example, a piece of software may be either a piece of source code (one asset) or a
piece of compiled code (another asset), and may exist in various formats at different stages of its
development (digital supports, printed paper). This separation is motivated by the fact that a threat may
concern one form at one stage, but be meaningless for another form at another stage.
The assets to be protected by the TOE are listed below. They are grouped according to whether it is data
created by and for the user (User data) or data created by and for the TOE (TSF data). For each asset it is
specified the kind of dangers that weigh on it.
7.1.1 User Data
D.APP_CODE
The code of the applets and libraries loaded on the card.
To be protected from unauthorized modification.
D.APP_C_DATA
Confidential sensitive data of the applications, like the data contained in an object, a static field of a package,
a local variable of the currently executed method, or a position of the operand stack.
To be protected from unauthorized disclosure.
D.APP_I_DATA
Integrity sensitive data of the applications, like the data contained in an object, a static field of a package, a
local variable of the currently executed method, or a position of the operand stack.
To be protected from unauthorized modification.
D.PIN
Any end-user's PIN.
To be protected from unauthorized disclosure and modification.
D.APP_KEYs
Cryptographic keys owned by the applets.
To be protected from unauthorized disclosure and modification.
Copyright Gemalto SA – 2012.
Page: 28/71
MultiApp ID V2.1 – JCS Security Target
7.1.2 TSF Data
D.JCS_CODE
The code of the Java Card System.
To be protected from unauthorized disclosure and modification.
D.JCS_DATA
The internal runtime data areas necessary for the execution of the Java Card CVM, such as, for instance, the
frame stack, the program counter, the class of an object, the length allocated for an array, any pointer used to
chain data-structures.
To be protected from monopolization and unauthorized disclosure or modification.
D.SEC_DATA
The runtime security data of the Java Card RE, like, for instance, the AIDs used to identify the installed
applets, the currently selected applet, the current context of execution and the owner of each object.
To be protected from unauthorized disclosure and modification.
D.API_DATA
Private data of the API, like the contents of its private fields.
To be protected from unauthorized disclosure and modification.
D.CRYPTO
Cryptographic data used in runtime cryptographic computations, like a seed used to generate a key.
To be protected from unauthorized disclosure and modification.

Other attacks are in general related to one of the above, and aimed at disclosing or modifying on-card
information. Nevertheless, they vary greatly on the employed means and threatened assets, and are thus
covered by quite different objectives in the sequel. That is why a more detailed list is given hereafter.
7.2.3 Identity Usurpation
T.SID.1
An applet impersonates another application, or even the Java Card RE, in order to gain illegal access to
some resources of the card or with respect to the end user or the terminal. See #.SID for details.
Directly threatened asset(s): D.SEC_DATA (other assets may be jeopardized should this attack succeed, for
instance, if the identity of the JCRE is usurped), D.PIN, D.APP_KEYs.

MultiApp ID V2.1 – JCS Security Target
T.SID.2
The attacker modifies the TOE's attribution of a privileged role (e.g. default applet and currently selected
applet), which allows illegal impersonation of this role. See #.SID for further details.
Directly threatened asset(s): D.SEC_DATA (any other asset may be jeopardized should this attack succeed,
depending on whose identity was forged).
7.2.4 Unauthorized Execution
T.EXE-CODE.1
An applet performs an unauthorized execution of a method. See #.EXE-JCS-CODE and #.EXE-APPLI-CODE
for details.
Directly threatened asset(s): D.APP_CODE.
T.EXE-CODE.2
An applet performs an execution of a method fragment or arbitrary data. See #.EXE-JCS-CODEEXE-JCSCODE and #.EXE-APPLI-CODE for details.
Directly threatened asset(s): D.APP_CODE.
T.NATIVE
An applet executes a native method to bypass a TOE security function such as the firewall. See #.NATIVE for
details.
Directly threatened asset(s): D.JCS_DATA.
T.EXE-CODE-REMOTE
The attacker performs an unauthorized remote execution of a method from the CAD. See #.EXE-JCS-CODE
and #.EXE-APPLI-CODE for details.
Directly threatened asset(s): D.APP_CODE.
Application note:
This threat concerns version 2.2 of the Java Card RMI, which allow external users (that is, other than on-card
applets) to trigger the execution of code belonging to an on-card applet. On the contrary, T.EXE-CODE.1 is
restricted to the applets under the TSF.
7.2.5 Denial of Service
T.RESOURCES
An attacker prevents correct operation of the Java Card System through consumption of some resources of
the card: RAM or NVRAM.
Directly threatened asset(s): D.JCS_DATA.
7.2.6 Card Management
T.INSTALL
The attacker fraudulently installs post-issuance of an applet on the card. This concerns either the installation
of an unverified applet or an attempt to induce a malfunction in the TOE through the installation process. See
#.INSTALL for details.
Copyright Gemalto SA – 2012.
Page: 31/71
MultiApp ID V2.1 – JCS Security Target
Directly threatened asset(s): D.SEC_DATA (any other asset may be jeopardized should this attack succeed,
depending on the virulence of the installed application).
T.DELETION
The attacker deletes an applet or a package already in use on the card, or uses the deletion functions to pave
the way for further attacks (putting the TOE in an insecure state). See #.DELETION (p 343) for details).
Directly threatened asset(s): D.SEC_DATA and D.APP_CODE.
7.2.7 Services
T.OBJ-DELETION
The attacker keeps a reference to a garbage collected object in order to force the TOE to execute an
unavailable method, to make it to crash, or to gain access to a memory containing data that is now being
used by another application. See #.OBJ-DELETION for further details.
Directly threatened asset(s): D.APP_C_DATA, D.APP_I_DATA and D.APP_KEYs.
7.2.8 Miscellaneous
T.PHYSICAL
The attacker discloses or modifies the design of the TOE, its sensitive data or application code by physical
(opposed to logical) tampering means. This threat includes IC failure analysis, electrical probing, unexpected
tearing, and DP analysis. That also includes the modification of the runtime execution of Java Card System or
SCP software through alteration of the intended execution order of (set of) instructions through physical
tampering techniques.
This threatens all the identified assets.
This threat refers to #.SCP.7, and all aspects related to confidentiality and integrity of code and data.
7.3
ORGANIZATIONAL SECURITY POLICIES
This section describes the organizational security policies to be enforced with respect to the TOE
environment.
OSP.VERIFICATION
This policy shall ensure the consistency between the export files used in the verification and those used for
installing the verified file. The policy must also ensure that no modification of the file is performed in between
its verification and the signing by the verification authority. See #.VERIFICATION for details.
7.4
ASSUMPTIONS
This section introduces the assumptions made on the environment of the TOE.
A.VERIFICATION
All the bytecodes are verified at least once, before the loading, before the installation or before the execution,
depending on the card capabilities, in order to ensure that each bytecode is valid at execution time.
Copyright Gemalto SA – 2012.
Page: 32/71
MultiApp ID V2.1 – JCS Security Target
A.DELETION
Deletion of applets, if available through the card manager, is secure. Refer to #.DELETION for details on this
assumption.
The rationale for this latter assumption is that even a Java Card System 2.1.1 TOE could be installed on a
product that includes applet deletion features. This assumes that these functions are secure with respect to
the SFRs herein.
A.APPLET
Applets loaded post-issuance do not contain native methods. The Java Card specification explicitly "does not
include support for native methods" ([JCVM222], §3.3) outside the API.
A.PROTECTION_AFTER_TOE_DELIVERY
It is assumed that security procedures are used after TOE delivery (at the end of phase 5) up to delivery to
the end consumer so as to maintain the confidentiality and integrity of the TOE and of its manufacturing,
personalization and test data (to prevent any possible copy, modification, retention, theft or unauthorized
use). This means that the phases after TOE delivery are assumed to be protected appropriately.

8 SECURITY OBJECTIVES
8.1
SECURITY OBJECTIVES FOR THE TOE
This section defines the security objectives to be achieved by the TOE.
8.1.1 Identification
O.SID
The TOE shall uniquely identify every subject (applet, or package) before granting it access to any service.
8.1.2 Execution
O.OPERATE
The TOE must ensure continued correct operation of its security functions. See #.OPERATE for details.
O.RESOURCES
The TOE shall control the availability of resources for the applications. See #.RESOURCES for details.
O.FIREWALL
The TOE shall ensure controlled sharing of data containers owned by applets of different packages or the
JCRE and between applets and the TSFs. See #.FIREWALL for details.
O.NATIVE
The only means that the Java Card VM shall provide for an application to execute native code is the
invocation of a method of the Java Card API, or any additional API. See #.NATIVE for details.
O.REALLOCATION
The TOE shall ensure that the re-allocation of a memory block for the runtime areas of the Java Card VM
does not disclose any information that was previously stored in that block.
Application note:
To be made unavailable means to be physically erased with a default value. Except for local variables that do
not correspond to method parameters, the default values to be used are specified in [JCVM222].
O.GLOBAL_ARRAYS_CONFID
The TOE shall ensure that the APDU buffer that is shared by all applications is always cleaned upon applet
selection.
The TOE shall ensure that the global byte array used for the invocation of the install method of the selected
applet is always cleaned after the return from the install method.
O.GLOBAL_ARRAYS_INTEG
The TOE shall ensure that only the currently selected applications may have a write access to the APDU
buffer and the global byte array used for the invocation of the install method of the selected applet.
Copyright Gemalto SA – 2012.

MultiApp ID V2.1 – JCS Security Target
8.1.3 Services
O.ALARM
The TOE shall provide appropriate feedback information upon detection of a potential security violation. See
#.ALARM for details.
O.TRANSACTION
The TOE must provide a means to execute a set of operations atomically. See #.TRANSACTION for details.
O.CIPHER
The TOE shall provide a means to cipher sensitive data for applications in a secure way. In particular, the
TOE must support cryptographic algorithms consistent with cryptographic usage policies and standards. See
#.CIPHER for details.
O.PIN-MNGT
The TOE shall provide a means to securely manage PIN objects. See #.PIN-MNGT for details.
Application note:
PIN objects may play key roles in the security architecture of client applications. The way they are stored and
managed in the memory of the smart card must be carefully considered, and this applies to the whole object
rather than the sole value of the PIN. For instance, the try counter's value is as sensitive as that of the PIN.
O.KEY-MNGT
The TOE shall provide a means to securely manage cryptographic keys. This concerns the correct
generation, distribution, access and destruction of cryptographic keys. See #.KEY-MNGT.
Application note:
O.KEY-MNGT, O.PIN-MNGT, O.TRANSACTION and O.CIPHER are actually provided to applets in the form
of Java Card APIs. Vendor-specific libraries can also be present on the card and made available to applets;
those may be built on top of the Java Card API or independently. Depending on whether they contain native
code or not, these proprietary libraries will need to be evaluated together with the TOE or not (see
#.NATIVE). In any case, they are not included in the Java Card System for the purpose of the present
document.
O.REMOTE
The TOE shall provide restricted remote access from the CAD to the services implemented by the applets on
the card. This particularly concerns the Java Card RMI services introduced in version 2.2.x of the Java Card
platform.
8.1.4 Object deletion
O.OBJ-DELETION
The TOE shall ensure the object deletion shall not break references to objects. See #.OBJ-DELETION for
further details.
8.1.5 Applet management
O.INSTALL
The TOE shall ensure that the installation of an applet performs as expected. (See #.INSTALL for details).
Copyright Gemalto SA – 2012.
Page: 35/71
MultiApp ID V2.1 – JCS Security Target
O.LOAD
The TOE shall ensure that the loading of a package into the card is safe.
Application note:
Usurpation of identity resulting from a malicious installation of an applet on the card may also be the result of
perturbing the communication channel linking the CAD and the card. Even if the CAD is placed in a secure
environment, the attacker may try to capture, duplicate, permute or modify the packages sent to the card. He
may also try to send one of its own applications as if it came from the card issuer. Thus, this objective is
intended to ensure the integrity and authenticity of loaded CAP files.
O.DELETION
The TOE shall ensure that both applet and package deletion perform as expected. (See #.DELETION for
details).
8.1.6 SCP
The Objectives described in this section are Objectives for the Environment in [PP-JCS-Open]. They become
Objectives for the TOE because the TOE in this ST includes the SCP.
O.SCP.RECOVERY
If there is a loss of power, or if the smart card is withdrawn from the CAD while an operation is in progress,
the SCP must allow the TOE to eventually complete the interrupted operation successfully, or recover to a
consistent and secure state.
This security objective refers to the security aspect #.SCP.1: The smart card platform must be secure with
respect to the SFRs. Then after a power loss or sudden card removal prior to completion of some
communication protocol, the SCP will allow the TOE on the next power up to either complete the interrupted
operation or revert to a secure state.
O.SCP.SUPPORT
The SCP shall support the TSFs of the TOE.
This security objective refers to the security aspect #.SCP.2-5:
(2) It does not allow the TSFs to be bypassed or altered and does not allow access to other low-level
functions than those made available by the packages of the API. That includes the protection of its private
data and code (against disclosure or modification) from the Java Card System.
(3) It provides secure low-level cryptographic processing to the Java Card System.
(4) It supports the needs for any update to a single persistent object or class field to be atomic, and possibly a
low-level transaction mechanism.
(5) It allows the Java Card System to store data in "persistent technology memory" or in volatile memory,
depending on its needs (for instance, transient objects must not be stored in non-volatile memory). The
memory model is structured and allows for low-level control accesses (segmentation fault detection).
O.SCP.IC
The SCP shall provide all IC security features against physical attacks.
This security objective refers to the point (7) of the security aspect #.SCP:
It is required that the IC is designed in accordance with a well-defined set of policies and Standards (likely
specified in another protection profile), and will be tamper resistant to actually prevent an attacker from
extracting or altering security data (like cryptographic keys) by using commonly employed techniques
(physical probing and sophisticated analysis of the chip). This especially matters to the management (storage
and operation) of cryptographic keys.

MultiApp ID V2.1 – JCS Security Target
8.1.7 CMGR
The Objectives described in this section are Objectives for the Environment in [PP-JCS-Open]. They become
Objectives for the TOE because the TOE in this ST includes the Card Manager.
O.CARD-MANAGEMENT
The card manager shall control the access to card management functions such as the installation, update or
deletion of applets. It shall also implement the card issuer's policy on the card.
The card manager is an application with specific rights, which is responsible for the administration of the
smart card. This component will in practice be tightly connected with the TOE, which in turn shall very likely
rely on the card manager for the effective enforcing of some of its security functions. Typically the card
manager shall be in charge of the life cycle of the whole card, as well as that of the installed applications
(applets). The card manager should prevent that card content management (loading, installation, deletion) is
carried out, for instance, at invalid states of the card or by non-authorized actors. It shall also enforce security
policies established by the card issuer.
8.2
SECURITY OBJECTIVES FOR THE OPERATIONAL ENVIRONMENT
This section introduces the security objectives to be achieved by the environment.
OE.VERIFICATION
All the bytecodes shall be verified at least once, before the loading, before the installation or before the
execution, depending on the card capabilities, in order to ensure that each bytecode is valid at execution
time. See #.VERIFICATION for details.
OE.APPLET
No applet loaded post-issuance shall contain native methods.
OE.PROTECTION_AFTER_TOE_DELIVERY
Security procedures shall be used after TOE delivery (at the end of phase 5) up to delivery to the end
consumer so as to maintain the confidentiality and integrity of the TOE and of its manufacturing,
personalization and test data (to prevent any possible copy, modification, retention, theft or unauthorized
use). This means that the phases after TOE delivery shall be protected appropriately.

9 SECURITY REQUIREMENTS
9.1
SECURITY FUNCTIONAL REQUIREMENTS
This section states the security functional requirements for the Java Card System – Open configuration. For
readability and for compatibility with the original Java Card System Protection Profile Collection - Standard
2.2 Configuration [PP/0305], requirements are arranged into groups. All the groups defined in the table below
apply to this Security Target.
Group
Core with Logical Channels
(CoreG_LC)
Installation
(InstG)
Applet deletion
(ADELG)
Remote Method Invocation
(RMIG)
Object deletion
(ODELG)
Secure carrier
(CarG)
Smart Card Platform (SCPG)
Card Manager
(CMGRG)
Description
The CoreG_LC contains the requirements concerning the runtime environment of the Java
Card System implementing logical channels. This includes the firewall policy and the
requirements related to the Java Card API. Logical channels are a Java Card specification
version 2.2 feature. This group is the union of requirements from the Core (CoreG) and the
Logical channels (LCG) groups defined in [PP/0305].
The InstG contains the security requirements concerning the installation of post-issuance
applications. It does not address card management issues in the broad sense, but only those
security aspects of the installation procedure that are related to applet execution.
The ADELG contains the security requirements for erasing installed applets from the card, a
feature introduced in Java Card specification version 2.2.
The RMIG contains the security requirements for the remote method invocation feature, which
provides a new protocol of communication between the terminal and the applets. This was
introduced in Java Card specification version 2.2.
The ODELG contains the security requirements for the object deletion capability. This provides
a safe memory recovering mechanism. This is a Java Card specification version 2.2 feature.
The CarG group contains minimal requirements for secure downloading of applications on the
card. This group contains the security requirements for preventing, in those configurations that
do not support on-card static or dynamic bytecodes verification, the installation of a package
that has not been bytecode verified, or that has been modified after bytecode verification.
The SCPG group contains the security requirements for the smart card platform, that is,
operating system and chip that the Java Card System is implemented upon.
The CMGRG group contains the security requirements for the card manager.
Subjects are active components of the TOE that (essentially) act on the behalf of users. The users of the
TOE include people or institutions (like the applet developer, the card issuer, the verification authority),
hardware (like the CAD where the card is inserted or the PCD) and software components (like the application
packages installed on the card). Some of the users may just be aliases for other users. For instance, the
verification authority in charge of the bytecode verification of the applications may be just an alias for the card
issuer.
Subjects (prefixed with an "S") are described in the following table:

Description
The applet deletion manager which also acts on behalf of the card issuer. It may be an
applet ([JCRE222], §11), but its role asks anyway for a specific treatment from the security
viewpoint. This subject is unique and is involved in the ADEL security policy defined in
§9.1.3.
Any applet instance.
The bytecode verifier (BCV), which acts on behalf of the verification authority who is in
charge of the bytecode verification of the packages. This subject is involved in the
PACKAGE LOADING security policy defined in §9.1.7.
The CAD represents the actor that requests, by issuing commands to the card, for RMI
services. It could play the role of the off-card entity that communicates with the
S.INSTALLER.
The installer is the on-card entity which acts on behalf of the card issuer. This subject is
involved in the loading of packages and installation of applets.
The runtime environment in which Java programs in a smart card are executed.
The bytecode interpreter that enforces the firewall at runtime.

Any object's field, static field or array position.
A package is a namespace within the Java programming language that may contain classes
and interfaces, and in the context of Java Card technology, it defines either a user library, or
one or several applets.
Objects (prefixed with an "O") are described in the following table:
Object
Description
O.APPLET
Any installed applet, its code and data.
The code of a package, including all linking information. On the Java Card platform, a
package is the installation unit.
Java class instance or array. It should be noticed that KEYS, PIN, arrays and applet
instances are specific objects in the Java programming language.
A method of a remote interface.
A remote object is an instance of a class that implements one (or more) remote interfaces. A
remote interface is one that extends, directly or indirectly, the interface java.rmi.Remote
([JCAPI222]).
These are instances of the class javacardx.rmi.RMIService. They are the objects that actually
process the RMI services.
A remote object reference. It provides information concerning: (i) the identification of a
remote object and (ii) the Implementation class of the object or the interfaces implemented
by the class of the object. This is the object's information to which the CAD can access.
O.CODE_PKG
O.JAVAOBJECT
O.REMOTE_MTHD
O.REMOTE_OBJ
O.RMI_SERVICE
O.ROR
Information (prefixed with an "I") is described in the following table:

I.APDU
Any APDU sent to or from the card through the communication channel.
JCVM Reference Data: objectref addresses of APDU buffer, JCRE-owned instances of
APDU class and byte array for install method
Remote object reference descriptors which provide information concerning: (i) the
identification of the remote object and (ii) the implementation class of the object or the
interfaces implemented by the class of the object. The descriptor is the only object's

9.1.1
CoreG_LC Security Functional Requirements
This group is focused on the main security policy of the Java Card System, known as the firewall. This policy
essentially concerns the security of installed applets. The policy focuses on the execution of bytecodes.
9.1.1.1 Firewall Policy
FDP_ACC.2/FIREWALL Complete access control
FDP_ACC.2.1/FIREWALL The TSF shall enforce the FIREWALL access control SFP on S.PACKAGE,
S.JCRE, S.JCVM, O.JAVAOBJECT and all operations among subjects and objects covered by the SFP.
Refinement:
The operations involved in the policy are:
• OP.CREATE,
• OP.INVK_INTERFACE,
• OP.INVK_VIRTUAL,
• OP.JAVA,
• OP.THROW,
• OP.TYPE_ACCESS.
FDP_ACC.2.2/FIREWALL The TSF shall ensure that all operations between any subject controlled by the
TSF and any object controlled by the TSF are covered by an access control SFP.
Application note:
Accessing array's components of a static array, and more generally fields and methods of static objects, is an
access to the corresponding O.JAVAOBJECT.
FDP_ACF.1/FIREWALL Security attribute based access control
FDP_ACF.1.1/FIREWALL The TSF shall enforce the FIREWALL access control SFP to objects based on
the following:
Subject/Object
S.PACKAGE
S.JCVM
S.JCRE
O.JAVAOBJECT
Attributes
LC Applet Selection Status
ActiveApplets, Currently Active Context
Selected Applet Context
Sharing, Context, LifeTime
FDP_ACF.1.2/FIREWALL The TSF shall enforce the following rules to determine if an operation among
controlled subjects and controlled objects is allowed:
•
R.JAVA.1 ([JCRE222]§6.2.8) An S.PACKAGE may freely perform any of OP.ARRAY_ACCESS,
OP.INSTANCE_FIELD,
OP.INVK_VIRTUAL,
OP.INVK_INTERFACE,
OP.THROW
or
OP.TYPE_ACCESS upon any O.JAVAOBJECT whose Sharing attribute has value "JCRE entry
point" or "global array".
•
R.JAVA.2 ([JCRE222]§6.2.8) An S.PACKAGE may freely perform any of OP.ARRAY_ACCESS,
OP.INSTANCE_FIELD, OP.INVK_VIRTUAL, OP.INVK_INTERFACE or OP.THROW upon any
O.JAVAOBJECT whose Sharing attribute has value "Standard" and whose Lifetime attribute has
value "PERSISTENT" only if O.JAVAOBJECT's Context attribute has the same value as the active
context.
•
R.JAVA.3 ([JCRE222]§6.2.8.10) An S.PACKAGE may perform OP.TYPE_ACCESS upon an
O.JAVAOBJECT whose Sharing attribute has value "SIO" only if O.JAVAOBJECT is being cast into
(checkcast) or is being verified as being an instance of (instanceof) an interface that extends the
Shareable interface.
Copyright Gemalto SA – 2012.
Page: 41/71
MultiApp ID V2.1 – JCS Security Target
•
R.JAVA.4 ([JCRE222], §6.2.8.6,) An S.PACKAGE may perform OP.INVK_INTERFACE upon an
O.JAVAOBJECT whose Sharing attribute has the value "SIO", and whose Context attribute has the
value "Package AID", only if the invoked interface method extends the Shareable interface and one
of the following applies:
(a) The value of the attribute Selection Status of the package whose AID is "Package AID" is
"Multiselectable»,
(b) The value of the attribute Selection Status of the package whose AID is "Package AID' is "Nonmultiselectable», and either "Package AID" is the value of the currently selected applet or
otherwise "Package AID" does not occur in the attribute ActiveApplets.
•
R.JAVA.5 An S.PACKAGE may perform an OP.CREATE only if the value of the Sharing
parameter(*) is "Standard".
FDP_ACF.1.3/FIREWALL The TSF shall explicitly authorize access of subjects to objects based on the
following additional rules:
1) The subject S.JCRE can freely perform OP.JAVA(...) and OP.CREATE, with the exception
given in FDP_ACF.1.4/FIREWALL, provided it is the Currently Active Context.
2) The only means that the subject S.JCVM shall provide for an application to execute native
code is the invocation of a Java Card API method (through OP.INVK_INTERFACE or
OP.INVK_VIRTUAL).
FDP_ACF.1.4/FIREWALL The TSF shall explicitly deny access of subjects to objects based on the following
additional rules:
1) Any subject with OP.JAVA upon an O.JAVAOBJECT whose LifeTime attribute has value
"CLEAR_ON_DESELECT" if O.JAVAOBJECT's Context attribute is not the same as the
Selected Applet Context.
2) Any subject attempting to create an object by the means of OP.CREATE and a
"CLEAR_ON_DESELECT" LifeTime parameter if the active context is not the same as the
Selected Applet Context.
Application note:
In the case of an array type, fields are components of the array ([JVM], §2.14, §2.7.7), as well as the length;
the only methods of an array object are those inherited from the Object class.
The Sharing attribute defines four categories of objects:
• Standard ones, whose both fields and methods are under the firewall policy,
• Shareable interface Objects (SIO), which provide a secure mechanism for inter-applet
communication,
• JCRE entry points (Temporary or Permanent), who have freely accessible methods but protected
fields,
• Global arrays, having both unprotected fields (including components; refer to JavaCardClass
discussion above) and methods.
When a new object is created, it is associated with the Currently Active Context. But the object is owned by
the applet instance within the Currently Active Context when the object is instantiated ([JCRE222], §6.1.3). An
object is owned by an applet instance, by the JCRE or by the package library where it has been defined
(these latter objects can only be arrays that initialize static fields of packages).
([JCRE222], Glossary) Selected Applet Context. The Java Card RE keeps track of the currently selected
Java Card applet. Upon receiving a SELECT command with this applet's AID, the Java Card RE makes this
applet the Selected Applet Context. The Java Card RE sends all APDU commands to the Selected Applet
Context.
While the expression "Selected Applet Context" refers to a specific installed applet, the relevant aspect to the
policy is the context (package AID) of the selected applet. In this policy, the "Selected Applet Context" is the
AID of the selected package.
([JCRE222], §6.1.2.1) At any point in time, there is only one active context within the Java Card VM (this is
called the Currently Active Context).

MultiApp ID V2.1 – JCS Security Target
The invocation of static methods (or access to a static field) is not considered by this policy, as there are no
firewall rules. They have no effect on the active context as well and the "acting package" is not the one to
which the static method belongs to in this case.
The Java Card platform, version 2.2.x introduces the possibility for an applet instance to be selected on
multiple logical channels at the same time, or accepting other applets belonging to the same package being
selected simultaneously. These applets are referred to as multiselectable applets. Applets that belong to a
same package are either all multiselectable or not ([JCVM222], §2.2.5). Therefore, the selection mode can be
regarded as an attribute of packages. No selection mode is defined for a library package.
An applet instance will be considered an active applet instance if it is currently selected in at least one logical
channel. An applet instance is the currently selected applet instance only if it is processing the current
command. There can only be one currently selected applet instance at a given time. ([JCRE222], §4).

FDP_IFC.1.1/JCVM The TSF shall enforce the JCVM information flow control SFP on S.JCVM, S.LOCAL,
S.MEMBER, I.DATA and OP.PUT (S1, S2, I).
Application note:
References of temporary Java Card RE entry points, which cannot be stored in class variables, instance
variables or array components, are transferred from the internal memory of the Java Card RE (TSF data) to
some stack through specific APIs (Java Card RE owned exceptions) or Java Card RE invoked methods
(such as the process (APDU apdu)); these are causes of OP.PUT (S1, S2, I) operations as well.

Application notes:
•
By users here it must be understood the ones associated to the packages (or applets) that act as
subjects of policies. In the Java Card System, every action is always performed by an identified user
interpreted here as the currently selected applet or the package that is the subject's owner. Means of
identification are provided during the loading procedure of the package and the registration of applet
instances.
•

9.1.2 INSTG Security Functional Requirements
This group combines the SFRs related to the installation of the applets, which addresses security aspects
outside the runtime. The installation of applets is a critical phase, which lies partially out of the boundaries of
the firewall, and therefore requires specific treatment. In this ST, loading a package or installing an applet
modeled as an importation of user data (that is, user application's data) with its security attributes (such as
the parameters of the applet used in the firewall rules).
FDP_ITC.2/Installer Import of user data with security attributes
FDP_ITC.2.1/Installer The TSF shall enforce the PACKAGE LOADING information flow control SFP
when importing user data, controlled under the SFP, from outside of the TOE.
Application note:
•
The most common importation of user data is package loading and applet installation on the behalf
of the installer. Security attributes consist of the shareable flag of the class component, AID and
version numbers of the package, maximal operand stack size and number of local variables for each
method, and export and import components (accessibility).
FDP_ITC.2.2/Installer The TSF shall use the security attributes associated with the imported user data.
FDP_ITC.2.3/Installer The TSF shall ensure that the protocol used provides for the unambiguous
association between the security attributes and the user data received.
Application note:
•
The format of the CAP file is precisely defined in Sun's specification ([JCVM222]); it contains the user
data (like applet's code and data) and the security attribute altogether. Therefore there is no
association to be carried out elsewhere.
FDP_ITC.2.4/Installer The TSF shall ensure that interpretation of the security attributes of the imported user
data is as intended by the source of the user data.
Application note:
•
Each package contains a package Version attribute, which is a pair of major and minor version
numbers ([JCVM222], §4.5). With the AID, it describes the package defined in the CAP file. When an
export file is used during preparation of a CAP file, the versions numbers and AIDs indicated in the
export file are recorded in the CAP files ([JCVM222], §4.5.2): the dependent packages Versions and
AIDs attributes allow the retrieval of these identifications.. Implementation-dependent checks may
occur on a case-by-case basis to indicate that package files are binary compatibles. However,
package files do have "package Version Numbers" ([JCVM222]) used to indicate binary compatibility
or incompatibility between successive implementations of a package, which obviously directly
concern this requirement.
FDP_ITC.2.5/Installer The TSF shall enforce the following rules when importing user data controlled under
the SFP from outside the TOE:
A package may depend on (import or use data from) other packages already installed. This
dependency is explicitly stated in the loaded package in the form of a list of package AIDs. The
loading is allowed only if, for each dependent package, its AID attribute is equal to a resident
package AID attribute, the major (minor) Version attribute associated to the former is equal (less than
or equal) to the major (minor) Version attribute associated to the latter ([JCVM222],§4.5.2).

Refinement:
The operations involved in the policy are:
• OP.DELETE_APPLET,
• OP.DELETE_PCKG,
• OP.DELETE_PCKG_APPLET.
FDP_ACC.2.2/ADEL The TSF shall ensure that all operations between any subject controlled by the TSF and
any object controlled by the TSF are covered by an access control SFP.

Selected Applet Context, Registered Applets, Resident Packages
O.CODE_PKG
package AID, dependent packages' AIDs, Static References
O.APPLET
Applet Selection Status
O.JAVAOBJECT
Owner, Remote
FDP_ACF.1.2/ADEL The TSF shall enforce the following rules to determine if an operation among controlled
subjects and controlled objects is allowed:
In the context of this policy, an object O is reachable if and only if one of the following conditions holds:
(1) the owner of O is a registered applet instance A (O is reachable from A),
(2) a static field of a resident package P contains a reference to O (O is reachable from P),
(3) there exists a valid remote reference to O (O is remote reachable), and
(4) there exists an object O' that is reachable according to either (1) or (2) or (3) above and O'
contains a reference to O (the reachability status of O is that of O').
The following access control rules determine when an operation among controlled subjects and objects is
allowed by the policy:

9.1.4 RMIG Security Functional Requirements
This group specifies the policies that control the access to remote objects and the flow of information that
takes place when the RMI service is used. The rules relate mainly to the lifetime of the remote references.
Information concerning remote object references can be sent out of the card only if the corresponding remote
object has been designated as exportable. Array parameters of remote method invocations must be allocated
on the card as global arrays. Therefore, the storage of references to those arrays must be restricted as well.
The JCRMI policy embodies both an access control and an information flow control policy.
FDP_ACC.2/JCRMI Complete access control
FDP_ACC.2.1/JCRMI The TSF shall enforce the JCRMI access control SFP on S.CAD, S.JCRE,
O.APPLET, O.REMOTE_OBJ, O.REMOTE_MTHD, O.ROR, O.RMI_SERVICE and all operations among
subjects and objects covered by the SFP.
Refinement:
The operations involved in the policy are:
• OP.GET_ROR,
• OP.INVOKE.
FDP_ACC.2.2/JCRMI The TSF shall ensure that all operations between any subject controlled by the TSF
and any object controlled by the TSF are covered by an access control SFP.
FDP_ACF.1/JCRMI Security attribute based access control
FDP_ACF.1.1/JCRMI The TSF shall enforce the JCRMI access control SFP to objects based on the
following:
Subject/Object
S.JCRE
O.REMOTE_OBJ
O.REMOTE_MTHD
O.RMI_SERVICE
Attributes
Selected Applet Context
Owner, class, Identifier, ExportedInfo
Identifier
Owner, Returned References
FDP_ACF.1.2/JCRMI The TSF shall enforce the following rules to determine if an operation among
controlled subjects and controlled objects is allowed:
•
R.JAVA.18 The S.CAD may perform OP.GET_ROR upon O.APPLET only if O.APPLET is the
currently selected applet, and there exists an O.RMI_SERVICE with a registered initial reference to
an O.REMOTE_OBJ that is owned by O.APPLET.
•
R.JAVA.19 The S.JCRE may perform OP.INVOKE upon O.RMI_SERVICE, O.ROR and
O.REMOTE_MTHD, only if, O.ROR is valid (as defined in [JCRE222], §8.5) and it belongs to the
Returned References of O.RMI_SERVICE, and if the Identifier of O.REMOTE_MTHD matches one
of the remote methods in the class of the O.REMOTE_OBJECT to which O.ROR makes reference.
FDP_ACF.1.3/JCRMI The TSF shall explicitly authorize access of subjects to objects based on the following
additional rules: none.
FDP_ACF.1.4/JCRMI The TSF shall explicitly deny access of any subject but S.JCRE to O.REMOTE_OBJ
and O.REMOTE_MTHD for the purpose of performing a remote method invocation.
Application note:
Copyright Gemalto SA – 2012.
Page: 55/71
MultiApp ID V2.1 – JCS Security Target
•
The validity of a remote object reference is specified as a lifetime characterization. The security
attributes involved in the rules for determining valid remote object references are the Returned
References of the O.RMI_SERVICE and the Active Applets (see FMT_REV.1.1/JCRMI and
FMT_REV.1.2/JCRMI). The precise mechanism by which a remote method is invoked on a remote
object is defined in detail in ([JCRE222], §8.5.2 and [JCAPI222]).
FDP_IFC.1/JCRMI Subset information flow control
FDP_IFC.1.1/JCRMI The TSF shall enforce the JCRMI information flow control SFP on S.JCRE, S.CAD,
I.RORD and OP.RET(S.JCRE,S.CAD,I.RORD).
Application note:
•
Array parameters of remote method invocations must be allocated on the card as global arrays
objects. References to global arrays cannot be stored in class variables, instance variables or array
components. The control of the flow of that kind of information has already been specified in
FDP_IFC.1.1/JCVM.
A remote object reference descriptor is sent from the card to the CAD either as the result of a successful
applet selection command ([JCRE222], §8.4.1), and in this case it describes, if any, the initial remote object
reference of the selected applet; or as the result of a remote method invocation ([JCRE222],§8.3.5.1).
Information flow policies control the flow of information between "subjects". This is a purely terminological
choice; those "subjects" can merely be passive containers. They are not to be confused with the "active
entities" of access control policies.
FDP_IFF.1/JCRMI Simple security attributes
FDP_IFF.1.1/JCRMI The TSF shall enforce the JCRMI information flow control SFP based on the
following types of subject and information security attributes:
Subject/Information
I.RORD
Attributes
ExportedInfo (Boolean value)
FDP_IFF.1.2/JCRMI The TSF shall permit an information flow between a controlled subject and controlled
information via a controlled operation if the following rules hold:
An operation OP.RET_RORD (S.JCRE, S.CAD, I.RORD) is permitted only if the attribute ExportedInfo
of I.RORD has the value "true" ([JCRE222], §8.5).
FDP_IFF.1.3/JCRMI The TSF shall enforce the No additional information flow control SFP rules.
FDP_IFF.1.4/JCRMI The TSF shall explicitly authorize an information flow based on the following rules:
OP.INVOKE is allowed if a successful OP.GET_ROR operation was previously successfully executed
on the O.ROR supplied in OP.INVOKE and if O.ROR has not been revoked.
FDP_IFF.1.5/JCRMI The TSF shall explicitly deny an information flow based on the following rules:
OP.INVOKE is denied if O.ROR supplied is not valid. OP.INVOKE is denied if the remote method
identifier supplied with O.ROR is not the one of a method belonging to the remote object referenced
by O.ROR.
Application note:
The ExportedInfo attribute of an I.RORD indicates whether the O.REMOTE_OBJ which I.RORD identifies is
exported or not (as indicated by the security attribute Exported of the O.REMOTE_OBJ).

MultiApp ID V2.1 – JCS Security Target
FMT_MSA.1/EXPORT Management of security attributes
FMT_MSA.1.1/EXPORT The TSF shall enforce the JCRMI access control SFP to restrict the ability to
modify the security attributes: ExportedInfo of an O.REMOTE_OBJ to its owner applet.
Application note:
The Exported status of a remote object can be modified by invoking its methods export() and unexport(), and
only the owner of the object may perform the invocation without raising a SecurityException
(javacard.framework.service.CardRemoteObject). However, even if the owner of the object may provoke the
change of the security attribute value, the Java Card RE could perform the modification itself.
FMT_MSA.1/REM_REFS Management of security attributes
FMT_MSA.1.1/REM_REFS The TSF shall enforce the JCRMI access control SFP to restrict the ability to
modify the security attributes: Returned References of O.RMI_SERVICE to its owner applet.
FMT_MSA.3/JCRMI Static attribute initialization
FMT_MSA.3.1/JCRMI The TSF shall enforce the JCRMI access control SFP and the JCRMI information
flow control SFP to provide restrictive default values for security attributes that are used to enforce the
SFP.
Application note:
•
Remote objects' security attributes are created and initialized at the creation of the object, and except
for the Exported attribute, the values of the attributes are not longer modifiable. The default value of
the Exported attribute is true. There is one default value for the SELECTed applet context that is the
default applet identifier's context, and one default value for the active context, that is "Java Card RE".
FMT_MSA.3.2/JCRMI The TSF shall allow the following role(s): none, to specify alternative initial values to
override the default values when an object or information is created.
FMT_REV.1/JCRMI Revocation
FMT_REV.1.1/JCRMI The TSF shall restrict the ability to revoke the Returned References of
O.RMI_SERVICE to the Java Card RE.
FMT_REV.1.2/JCRMI The TSF shall enforce the rules that determine the lifetime of remote object
references.
Application note:
The rules are described in [JCRE222], §8.5.
FMT_SMF.1/JCRMI Specification of Management Functions
FMT_SMF.1.1/JCRMI The TSF shall be capable of performing the following management functions:
•
Modify the security attribute ExportedInfo of O.REMOTE_OBJ.
•
Modify the security attribute Returned References of O.RMI_SERVICE.
FMT_SMR.1/JCRMI Security roles
FMT_SMR.1.1/JCRMI The TSF shall maintain the roles: applet.
FMT_SMR.1.2/JCRMI The TSF shall be able to associate users with roles.
Application note:
Applets own Remote interface objects and may choose to allow or forbid their exportation, which is managed
through a security attribute.

9.1.6 CarG Security Functional Requirements
This group includes requirements for preventing the installation of packages that have not been bytecode
verified, or that has been modified after bytecode verification.
FCO_NRO.2/CM Enforced proof of origin
FCO_NRO.2.1/CM The TSF shall enforce the generation of evidence of origin for transmitted application
packages at all times.
Application note: Upon reception of a new application package for installation, the card manager shall first
check that it actually comes from the verification authority. The verification authority is the entity responsible
for bytecode verification.
FCO_NRO.2.2/CM The TSF shall be able to relate the identity of the originator of the information, and the
application package contained in the information to which the evidence applies.
FCO_NRO.2.3/CM The TSF shall provide a capability to verify the evidence of origin of information to
recipient given no limitation.
FDP_IFC.2/CM Complete information flow control
FDP_IFC.2.1/CM The TSF shall enforce the PACKAGE LOADING information flow control SFP on
S.INSTALLER, S.BCV, S.CAD, and I.APDU and all operations that cause that information to flow to and
from subjects covered by the SFP.
FDP_IFC.2.2/CM The TSF shall ensure that all operations that cause any information in the TOE to flow to
and from any subject in the TOE are covered by an information flow control SFP.
Application note: The subjects covered by this policy are those involved in the loading of an application
package by the card through a potentially unsafe communication channel:
The operations that make information to flow between the subjects are those enabling to send a message
through and to receive a message from the communication channel linking the card to the outside world. It is
assumed that any message sent through the channel as clear text can be read by the attacker. Moreover, the
attacker may capture any message sent through the communication channel and send its own messages to
the other subjects.
The information controlled by the policy is the APDUs exchanged by the subjects through the communication
channel linking the card and the CAD. Each of those messages contain part of an application package that is
required to be loaded on the card, as well as any control information used by the subjects in the
communication protocol.
FDP_IFF.1/CM Simple security attributes

• The Issuer, behaving as the BCV, can load it through a secure channel, after having verified
the applet.
• The Issuer can load an applet with a DAP specifying that it has been verified by the BCV.
• The Operator, having checked the applet can load it through a secure channel.
FDP_IFF.1.5/CM The TSF shall explicitly deny an information flow based on the following rules:
• An applet, not verified by a BCV cannot be loaded.
FDP_UIT.1/CM Data exchange integrity
FDP_UIT.1.1/CM The TSF shall enforce the PACKAGE LOADING information flow control SFP to be able
to receive user data in a manner protected from modification, deletion, insertion, and replay errors.
FDP_UIT.1.2/CM The TSF shall be able to determine on receipt of user data, whether modification,
deletion, insertion, replay of some of the pieces of the application sent by the CAD has occurred.
Application note:
Modification errors should be understood as modification, substitution, unrecoverable ordering change of data
and any other integrity error that may cause the application package to be installed on the card to be different
from the one sent by the CAD.
FIA_UAU.1/CM Timing of authentication
FIA_UAI.1.1/CM The TSF shall allow
• JCAPI with already installed applets
• APDUs for Applets
• RMI for Applets
on behalf of the user to be performed before the user is authenticated.
Application note:
This authentication of the card manager is a strong authentication as soon as the TOE leaves the protected
environment of audited facilities. For this purpose, keys are diversified.
FIA_UAU.1.2/CM The TSF shall require each user to be successfully authenticated before allowing any other
TSF-mediated actions on behalf of that user.
FIA_UID.1/CM Timing of identification
FIA_UID.1.1/CM The TSF shall allow
• JCAPI with already installed applets
• APDUs for Applets
• RMI for Applets

An operation OP.PUT (S1, S.MEMBER, I) is allowed if and only if the active context
is "JCRE"; other OP.PUT operations are allowed regardless of the active context's
value.
Upon allocation of a resource to class instances and arrays, any previous
information content of the resource is made unavailable
Only the S.JCRE can modify the security attributes the active context, the selected
applet context security attributes.
Only the S.JCVM can modify the security attributes the active context, the currently
active Context and the Active Applets security attributes.
only secure values are accepted for all the security attributes of subjects and
objects defined in the FIREWALL access control SFP and the JCVM information
flow control SFP.

Only the JCRE can modify the list of registered applets' AIDs.
Only secure values are accepted for the AIDs of registered applets.
The TSF shall maintain the following list of security attributes belonging to
individual users:
• package AID
• Applet's version number
• registered applet's AID
• applet selection status ([JCVM222], §6.5)
The TSF shall require each user to be successfully identified before allowing any
other TSF-mediated actions on behalf of that user.
Initial applet selection is performed as described in [JCRE222]§4
Applet selection is performed after a successful SELECT FILE command as
described in [JCRE222]§4.

10.1.5 SF.INST: Installer
the protocol used provides for the unambiguous association between the security
attributes and the user data received:
The format of the CAP file is precisely defined in Sun's specification ([JCVM222]); it
contains the user data (like applet's code and data) and the security attribute
altogether.
Each package contains a package Version attribute, which is a pair of major and
minor version numbers ([JCVM222], §4.5). With the AID, it describes the package
defined in the CAP file. When an export file is used during preparation of a CAP
file, the versions numbers and AIDs indicated in the export file are recorded in the
CAP files ([JCVM222], §4.5.2): the dependent packages Versions and AIDs
attributes allow the retrieval of these identifications.. Implementation-dependent

checks may occur on a case-by-case basis to indicate that package files are binary
compatibles. However, package files do have "package Version Numbers"
([JCVM222]) used to indicate binary compatibility or incompatibility between
successive implementations of a package, which obviously directly concern this
requirement.
A package may depend on (import or use data from) other packages already
installed. This dependency is explicitly stated in the loaded package in the form of a
list of package AIDs. The loading is allowed only if, for each dependent package,
its AID attribute is equal to a resident package AID attribute, the major (minor)
Version attribute associated to the former is equal (less than or equal) to the major
(minor) Version attribute associated to the latter ([JCVM222],§4.5.2).
The TSF shall maintain the roles: the installer
The TSF shall preserve a secure state when the following types of failures occur:

OP.DELETE_APPLET upon an O.APPLET only if,
(1) S.ADEL is currently selected,
(2) O.APPLET is deselected and
(3) there is no O.JAVAOBJECT owned by O.APPLET such that either
O.JAVAOBJECT is reachable from an applet instance distinct from
O.APPLET, or O.JAVAOBJECT is reachable from a package P, or
([JCRE222], §8.5) O.JAVAOBJECT is remote reachable.
([JCRE222], §11.3.4.1, Multiple Applet Instance Deletion). The S.ADEL may
perform OP.DELETE_APPLET upon several O.APPLET only if,
(1) S.ADEL is currently selected,
(2) every O.APPLET being deleted is deselected and
(3) there is no O.JAVAOBJECT owned by any of the O.APPLET being
deleted such that either O.JAVAOBJECT is reachable from an applet
instance distinct from any of those O.APPLET, or O.JAVAOBJECT is
reachable from a package P, or ([JCRE222], §8.5) O.JAVAOBJECT is
remote reachable.

either O.JAVAOBJECT is reachable from an applet instance not
being deleted, or O.JAVAOBJECT is reachable from a package
not being deleted, or ([JCRE222],§8.5) O.JAVAOBJECT is remote
reachable.
However, the S.ADEL may be granted privileges ([JCRE222], §11.3.5) to bypass
the preceding policies. For instance, the logical deletion of an applet renders it unselectable; this has implications on the management of the associated TSF data
(see application note of FMT_MTD.1.1/JCRE).
Only the S.ADEL can delete O.CODE_PKG or O.APPLET from the card.
Upon deallocation of a resource from the applet instances and/or packages
when one of the deletion operations in FDP_ACC.2.1/ADEL is performed on
them, any previous information content of the resource is made unavailable.
Requirements on de-allocation during applet/package deletion are described in
[JCRE222], §11.3.4.1, §11.3.4.2 and §11.3.4.3.

10.1.7 SF.RMI: Remote Method Invocation
This SF handles RMI security features: access control, information flow control, the related security attributes
and their management.
The S.CAD may perform OP.GET_ROR upon an O.APPLET only if O.APPLET is
the currently selected applet, and there exists an O.RMI_SERVICE with a
registered initial reference to an O.REMOTE_OBJ that is owned by O.APPLET.
The S.JCRE may perform OP.INVOKE upon O.RMI_SERVICE, O.ROR and
O.REMOTE_MTHD, only if, O.ROR is valid (as defined in [JCRE222], §8.5) and
belongs to the value of the attribute Returned References of O.RMI_SERVICE, and
the attribute Identifier of O.REMOTE_MTHD matches one of the remote methods
in the class, indicated by the security attribute class, of the O.REMOTE_OBJECT
to which O.ROR makes reference.
Only the S.JCRE can perform a remote method invocation on O.REMOTE_OBJ
and O.REMOTE_MTHD.
Only the S.JCRE can modify the security attributes: ActiveApplets.
The modification of the ActiveApplets security attribute should be performed in
accordance with the rules given in [JCRE222], §4.
Only its owner can modify the security attributes: Exported of an
O.REMOTE_OBJ.
The Exported status of a remote object can be modified by invoking its methods
export() and unexport(), and only the owner of the object may perform the
invocation
without
raising
a
SecurityException
(javacard.framework.service.CardRemoteObject). However, even if the owner of
the object may provoke the change of the security attribute value, the Java Card
RE could perform the modification itself.
Only its owner can modify the security attributes: Returned References of an
O.RMI_SERVICE.

longer modifiable. The default value of the Exported attribute is true. There is one
default value for the SELECTed applet context that is the default applet identifier's
context, and one default value for the active context, that is "Java Card RE".
Only the S.JCRE can revoke the Returned References security attribute of an
O.RMI_SERVICE,
[JCRE222], §8.5 describes the rules that determine the lifetime of remote object
references.
The TSF shall maintain the roles: Java Card RMI
The TSF shall be capable of performing the following management functions:
• Modify the security attribute Exported of an O.REMOTE_OBJ.
• Modify the security attribute Returned References of an O.RMI_SERVICE.
An operation OP.RET_RORD (S.JCRE, S.CAD, I.RORD) is permitted only if the
attribute ExportedInfo I.RORD has the value "true" ([JCRE222], §8.5)
OP.INVOKE is allowed if a successful OP.GET_ROR operation was previously
successfully executed on the O.ROR supplied in OP.INVOKE and if O.ROR has
not been revoked.
OP.INVOKE is denied if O.ROR supplied is not valid. OP.INVOKE is denied if the
remote method identifier supplied with O.ROR is not the one of a method belonging
to the remote object referenced by O.ROR.
