Abstract :
Sharing of services among wired and wireless networks provides users with more variety of services. In this paper, we concentrate on how to achieve secure service sharing for mobile users in an aggregation of heterogeneous networks. Our approach is to extended the service network graph (SNG) concept to handle mobile users rambling within a guest network which is part of an SNG. Adhering to this approach, if the guest network has delegated authentication authority to the home network, the extended service network graph can also set up a transient account by sharing a secret between the user and the authentication servers on the guest network and the home network. This may serve as a temporary account and facilitates mobile users to obtain services on the fly. Lastly, we discuss how to use the extended SNG for mobile IP authentication
