Title: Allocation of Application Identifiers (AIDs)
1 Background
============
In a multi-application environment, a flexible application selection
method is an obvious requirement. To achieve this, TSG-T3 would like
to implement the ISO/IEC concept for application identification as
defined in ISO/IEC 7816-5. This International Standard specifies
application identifiers (AIDs) and the registration of such
identifiers. These identifiers allow each application and each
application provider to be uniquely identified. TSG-T3 does not see
any feasible alternative to the international approach standardised by
ISO/IEC.
The AID is used to explicitly select an application in a
multi-application smart card, e.g. a specific USIM application (there
may be more than one) or a GSM application on the same card. An AID
consists of an RID (Registered Application Provider Identifier) and a
PIX (Proprietary application identifier extension).
As an example, in the case of telecommunications cards issued by ETSI,
the RID is the unique ETSI RID issued by ISO/IEC followed by the PIX
which identifies the application and the application issuer.
Currently, two ETSI applications have been defined (GSM and SIM
Application Toolkit). Details of the process and the precise format of
the ETSI-AIDs are specified in the ETSI guide EG-201 220. See also
T3-99156 (attached) for further information.
It has been identified by TSG-T3 that AIDs need to be managed for 3GPP
applications. There are, however, some issues which need to be
resolved.
2 3GPP AID Administration
=========================
Administration means obtaining an RID from ISO/IEC, and issuing and
maintaining the list of AIDs. Issue and maintenance of the AIDs
consists of assigning and registering a unique identifier to an
application upon request by the appropriate 3GPP committee. It should
be noted that the PIX could be structured in such a way that there is
no need for any further action by the administration authority as has
been achieved in EG 201 200 (e.g., there is no need to assign
identifiers to issuers or maintain a list of issuers).
According to the understanding of TSG-T3 it is possible that 3GPP as
“an international organisation in charge of specification of IC card
applications” (ISO/IEC 7816-5) could apply for an RID from ISO/IEC and
administer AIDs. The fee charged by the ISO/IEC registration authority
(Tele Danmark) to issue a RID is less than USD 100.
3 Conclusion and Proposals
==========================
The arguments given above leads T3 to the following options:
*
one of the partners applies for an RID (possibly ETSI which
already has an RID) and administers the list of AIDs for 3GPP;
*
3GPP as an organisation in its own right applies for an RID, and
3GPP or one of the partners maintains the list of AIDs for 3GPP;
*
each partner independently applies for an RID and T3 specifies the
structure of the PIX in a 3GPP document which applies to all
Partners.
T3 believes that the second option presented is the most suitable
approach. 3GPP would create a new document similar to the ETSI guide
EG 201 220 for the structure and the maintenance of AIDs.
