End-to-End Security Establishment Through Operators: SIP Experiment

In this paper, the authors propose to experiment a secure multimedia session establishment in a fully open environment like Internet. Users equipped with multi-capacity devices can benefit from the authentication support of their operators to mutually authenticate, and secure their exchanges. Multi-operator crossed authentication can also take place under a previously signed agreement. In this paper, a SIP experiment with integration of SIM-based authentication is successfully conducted, thus demonstrating the feasibility of the end-to-end security establishment approach through operators.
