45、e The present document describes the security features and mechanisms to bootstrap authentication and key agreement for application security. Candidate applications to use this bootstrapping mechanism include but are not restricted to subscriber certificate distribution TS 33.221 5. Subscriber certi

46、ficates support services whose provision mobile operator assists, as well as services that mobile operator provides. The scope of this specification includes generic bootstrapping functions, an architecture overview and the detailed procedure how to bootstrap the credential. Clause 4 of this specifi

47、cation describes a mechanism, called GBA_ME, to bootstrap authentication and key agreement, which does not require any changes to the UICC. Clause 5 of this specification describes a mechanism, called GBA_U, to bootstrap authentication and key agreement, which does require changes to the UICC, but p

48、rovides enhanced security by storing certain derived keys on the UICC. Annex I of this specification describes a mechanism, called 2G GBA, to bootstrap authentication and key agreement using 2G AKA protocol. Annex M of this specification describes a mechanism, called GBA_Digest, to bootstrap authent

49、ication and key agreement using HTTP Digest protocol with SIP Digest credentials. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.
