Introduction This section provides an introduction on the context of GAA and some clarification of why this TR was written (with some reference to related 3GPP Technical Specifications and Technical Re
25、ports). Figure 1: Schematic illustration of GAA A number of applications share a need for mutual authentication between a client (i.e. the UE ) and an application server before further communication can take place. Examples include (but are not limited to) communication between a client and a presen
26、ce server (possibly via an authentication proxy), communication with a PKI portal where a client requests a digital certificate, communication with a Mobile Broadcast / Multicast Service (MBMS) content server, a BM-SC, etc. Since a lot of applications share this common need for a peer authentication
27、 mechanism, it has been considered useful to specify a Generic Authentication Architecture (GAA). This GAA describes a generic architecture for peer authentication that can a priori serve for any (present and future) application. This TR can be considered as a framework document for the generic auth
28、entication architecture as is illustrated in Figure 1. GBA, HTTPS and the Authentication Proxy (AP), and Certificates are the basic building blocks of the GAA in 3GPP Release 6 and they are specified each in a separate TS. Later on, many additions were made to accommodate specific needs for various
29、use cases. How the different GAA and GBA related specifications and technical reports fit together in GAA is explained in this document. NE GBA HTTPS and AP Certificates HSS UE GAA ETSI ETSI TR 133 919 V15.0.0 (2018-07)53GPP TR 33.919 version 15.0.0 Release 151 Scope This 3GPP Technical Report aims
30、to give an overview of the different mechanisms that mobile applications can rely upon for authentication between server and client (i.e. the UE). Additionally it provides guidelines related to the use of GAA and to the choice of authentication mechanism in a given situation and for a given applicat
31、ion. To this end the TR puts the different 3GPP GAA related specifications, into perspective. It clarifies the logic for having the technical specifications and technical reports, sketches their content and explains the inter-relation between these 3GPP TSs and TRs and their relation with this TR. T
32、he heart of GAA consists out of the Generic Bootstrapping Architecture (GBA): The GBA core specifications consist out of TS 33.220, TS 24.109 and TS 29.109. Figure 2 depicts protocols used over the GBA core interfaces and the relationships between different GBA core specifications. Figure 2: Relatio
33、nships between GBA core specifications and the protocols used by GBA interfaces GBA in turn is then used by many other TSs and TRs to enable specific usages e.g. HTTPS, subscriber certificates. 2 References The following documents contain provisions which, through reference in this text, constitute

One is based on a secret shared between the communicating entities, the other one is based on (public, private) key pairs and digital
49、certificates. Also in GAA these are the two options that are a priori available for mobile applications as is illustrated in Figure 3.
