Full Description

ETSI TR 133 919 aims to give an overview of the different mechanisms that mobile applications can relyupon for authentication between server and client (i.e. the UE). Additionally it provides guidelines related to the use ofGAA and to the choice of authentication mechanism in a given situation and for a given application.

To this end the TR puts the different 3GPP GAA related specifications, into perspective. It clarifies the logic for havingthe technical specifications and technical reports, sketches their content and explains the inter-relation between these3GPP TSs and TRs and their relation with this TR.

The heart of GAA consists out of the Generic Bootstrapping Architecture (GBA): The GBA core specifications consistout of TS 33.220, TS 24.109 and TS 29.109. Figure 2 depicts protocols used over the GBA core interfaces and therelationships between different GBA core specifications.
