Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Smart Card Platform (SCP).
It is based on work originally done in the 3GPP in TSG-terminals WG3 and ETSI SMG.
The contents of the present document are subject to continuing work within TC SCP and may change following formal
TC SCP approval. If TC SCP modifies the contents of the present document, it will then be republished by ETSI with
an identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x: the first digit:
0 early working draft;
1 presented to TC SCP for information;
2 presented to TC SCP for approval;
3 or greater indicates TC SCP approved document under change control.
y: the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z: the third digit is incremented when editorial only changes have been incorporated in the document.

Release 8 6 ETSI TS 102 224 V8.0.0 (2008-10)
1 Scope
The present document provides standardized security mechanisms in conjunction with the Card Application Toolkit for
the interface between a Network Entity and a UICC.
The security mechanisms which are specified are independent of applications.
The present document describes the functional requirements of the security mechanisms with the implementation detail
of these mechanisms being described in TS 102 225 [2].
Within the scope of the present document, the UICC refers here to an ICC which support at least one application in
order to access a cellular network.
The ICC is considered as a platform, which is based on TS 102 221 [5].
2 References
References are either specific (identified by date of publication and/or edition number or version number) or
non-specific.
• For a specific reference, subsequent revisions do not apply.
• In the case of a reference to a TC SCP document, a non specific reference implicitly refers to the latest version
of that document in the same Release as the present document.
• Non-specific reference may be made only to a complete document or a part thereof and only in the following
cases:
- if it is accepted that it will be possible to use all future changes of the referenced document for the
purposes of the referring document;
- for informative references.
Referenced documents which are not found to be publicly available in the expected location might be found at
http://docbox.etsi.org/Reference.
For online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably,
the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the
reference should, as far as possible, remain valid for the expected life of the document. The reference shall include the
method of access to the referenced document and the full network address, with the same punctuation and use of upper
case and lower case letters.

3 Definitions and abbreviations
3.1 Definitions
For the purpose of the present document, the following terms and definitions apply:
application layer: layer above the transport layer on which the application messages are exchanged between the
sending and receiving applications
application message: package of commands or data sent from the sending application to the receiving application, or
vice versa, independently of the transport mechanism
NOTE: An application message is transformed with respect to a chosen transport layer and chosen level of
security into one or more secured packets.
counter: mechanism or data field used for keeping track of a message sequence
NOTE: This could be realized as a sequence oriented or time stamp derived value maintaining a level of
synchronization.
cryptographic checksum: string of bits derived from some secret information, (e.g. a secret key), part or all of the
application message, and possible further information (e.g. part of the security header)
NOTE: The secret key is known to the sending entity and to the receiving entity. The Cryptographic checksum is
often referred to as Message Authentication Code (MAC).
digital signature: string of bits derived from some secret information (e.g. a secret key) the complete application
message, and possible further information (e.g. part of the security header)
NOTE: The secret information is known only to the sending entity. Although the authenticity of the digital
signature can be proved by the receiving entity, the receiving entity is not able to reproduce the digital
signature without knowledge of the secret information owned by the sending entity.
receiving application: entity to which the application message is destined
receiving entity: entity where the secured packet is received (e.g. SMS-SC, UICC, USSD entry point, or dedicated
toolkit server) and where the security mechanisms are utilized
NOTE: The receiving entity processes the secured packets.

---------------------- Page: 7 ----------------------
Release 8 8 ETSI TS 102 224 V8.0.0 (2008-10)
redundancy check: string of bits derived from the application message and possible further information for the purpose
of detecting accidental changes to the message, without the use of any secret information
secured packet: information flow on top of which the level of required security has been applied
NOTE: An application message is transformed with respect to a chosen Transport Layer and chosen level of
security into one or more secured packets.
security header: that part of the secured packet which consists of all security information
EXAMPLE: Counter, key identification, indication of security level, checksum or digital signature).
sender identification: simple verification of the identity of the sending entity by the receiving entity comparing the
sender identity with an a priori stored identity of the sender at the receiving entity
sending application: entity generating an application message to be sent
sending entity: entity from which the secured packet originates (e.g. SMS-SC, UICC, USSD entry point, or dedicated
toolkit server) and where the security mechanisms are invoked
NOTE: The sending entity generates the secured packets to be sent.
status code: indication that a message has been received (correctly or incorrectly, indicating reason for failure)
transport layer: layer responsible for transporting secured packets through the network
NOTE: The transport layer implements one or more transport mechanisms, (e.g. SMS or USSD).
unsecured acknowledgement: status code included in a response message
