Abstract

Two novel mutual authentication and key exchange protocols with anonymity are proposed for different roaming scenarios in the global mobility network (GLOMONET). The proposed protocols have new features, such as identity anonymity and one-time session key progression. Identity anonymity protects mobile users' privacy in the roaming network environment. One-time session key progression frequently renews the session key for mobile users and reduces the risk of using a compromised session key to communicate with visited networks. It is shown that the computation complexity of the proposed protocols is similar to the existing one appeared in the literature, while the security has been significantly enhanced.
