The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present do
21、cument, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change co
22、ntrol. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction This section provides an introduction on the context of GAA
23、 and some clarification of why this TR was written (with some reference to related 3GPP Technical Specifications and Technical Reports). 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 b
24、efore further communication can take place. Examples include (but are not limited to) communication between a client and a presence server (possibly via an authentication proxy), communication with a PKI portal where a client requests a digital certificate, communication with a Mobile Broadcast / Mu
25、lticast Service (MBMS) content server, a BM-SC, etc. Since a lot of applications share this common need for a peer authentication mechanism, it has been considered useful to specify a Generic Authentication Architecture (GAA). This GAA describes a generic architecture for peer authentication that ca
26、n a priori serve for any (present and future) application. This TR can be considered as a framework document for the generic authentication 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 Rele
27、ase 6 and they are specified each in a separate TS. Later on, many additions were made to accommodate specific needs for various use cases. NEGBA HTTPS and AP Certificates HSS UE GAA ETSI ETSI TR 133 919 V13.0.0 (2016-01)53GPP TR 33.919 version 13.0.0 Release 13How the different GAA and GBA related
28、specifications and technical reports fit together in GAA is explained in this document. ETSI ETSI TR 133 919 V13.0.0 (2016-01)63GPP TR 33.919 version 13.0.0 Release 131 Scope This 3GPP Technical Report aims to give an overview of the different mechanisms that mobile applications can rely upon for au
29、thentication 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 application. To this end the TR puts the different 3GPP GAA related specifications, into perspective.
30、 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. The heart of GAA consists out of the Generic Bootstrapping Architecture (GBA): The GBA core sp
31、ecifications 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: Relationships between GBA core specifications and the protocols used by GBA interfaces GBA in turn i
32、s 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 provisions of the present document.

47、nerally speaking two types of authentication mechanisms. One is based on a secret shared between the communicating entities, the other one is based on (public, private) key pairs and digital certificates. Also in GAA these are the two options that are a priori available for mobile applications as is
48、 illustrated in Figure 3. GAA Shared Secret GBA TS33.220 Certificates SSC TS33.221 Figure 3: GAA schematic overview 4.2 Authentication using shared secret There are several authentication protocols that rely on a pre-shared secret between the two communicating entities. Popular examples include HTTP
49、 Digest, Pre-Shared Key TLS, IKE with pre-shared secret and a priori any mechanism based on username and password. The main problem with these mechanisms is how to agree on this pre-shared secret. Clause 5.2 and GBA TS 33.220 2 describe how in a mobile context an AKA based mechanism can be used to provide both communicating entities with a pre-shared secret.
