33.2203GPPGeneric Authentication Architecture (GAA)Generic Bootstrapping Architecture (GBA)TS
This annex specifies the implementation option to allow the use of SIM cards or SIMs on UICC for GBA. The procedure specified in this annex is called 2G GBA. 2G GBA allows access to applications in a more secure way than would be possible with the use of passwords or with GSM without enhancements. It may be useful for operators who have not yet fully deployed USIMs.
The usage of the term 2G GBA in this specification does not restrict the usage of GBA over only 2G access networks i.e. GSM access. Similarly the use of the term 3G GBA in this specification does not restrict the usage of GBA over only 3G access networks i.e. UMTS. In this specification the term 2G GBA refers to the usage of a SIM card or SIM on UICC, while 3G GBA or GBA on its own, refers and to the usage of a USIM/ISIM on a UICC.
Clauses 4 and 5 of the present document do not apply to this annex unless explicitly stated.
