Trust framework and service delivery in SPICE

Today's network operators are envisioning a converged communication future where the Internet meets the telecommunication world. The EU IST SPICE (Service Platform for Innovative Communication Environment) project goes one step closer to this future by developing a service platform for creating mobile services based on the web services paradigm of the Internet, combined with the capabilities offered by the telco world such as unified billing and charging, presence information, identity management, etc. This paper describes the trust framework of SPICE which is responsible for identity management and access control in such a combined environment with an example scenarios showing how access to services is controlled in SPICE.
