Generic Authentication Architecture (GAA); Access to network application functions using Hypertext Transfer Protocol over Transport Layer Security (HTTPS)
The present document specifies secure access methods to Network Application Functions (NAF) using HTTP over TLS in the Generic Authentication Architecture (GAA), and provides Stage 2 security requirements, principles and procedures for the access. The present document describes both direct access to an Application Server (AS) and access to an Application Server through an Authentication Proxy (AP).
NOTE: Any application specific details for access to Applications Servers are not in scope of this specification and are covered in separate documents. An example of such a document is TS 33.141 [5], which specifies the security for presence services.
