Abstract
|
Controlled access to resources offered by network operators and service providers is a key component for any commercial deployment of a Beyond-3G (B3G) communication system: complex scenarios involving users accessing advanced multimedia services using heterogeneous network technologies in different administrative domains do require tight access control. This paper presents an authorization model that provides secured access control to network-dependent as well as to applicative services. Stemming from a new identity model that not only protects user's privacy but also allows for more powerful services, advanced authorization procedures are defined. We describe how innovative enhancements to authentication protocols easily and profitably make them usable for the purpose of authorization. A special focus is put on new registration procedures that can be built on top of these improvements in order to provide new security features to the infrastructure (e.g. granular access control rules, generic security model) while offering new security services to the end user (e.g. anonymity, fast attach procedure).
