Abstract
A global mobility communication network (GLOMONT) allows mobile users to obtain roaming service, in which the service is provided by a foreign agent when users are in foreign territory. Therefore, the mutual authentication and key agreement are integral to the GLOMONT. In addition, the conditional privacy preservation, which enhances anonymity and fairness, is another important issue. In other words, mobile users can receive service without leaking an identity to anyone except the home agent, and the home agent should receive the payment from mobile users. Thus, in this paper, we propose a conditional privacy preservation authentication scheme in GLOMONT. The secure analyses show that our proposed scheme can achieve the security requirements and against many well-known attacks.
