【Abstract】 The problem of identity authentication and key agreement is a very important one about security in wireless communications.We propose a wireless mutual authentication and key agreement protocol to resolve this problem.In the protocol,a mobile user can be provided with anonymous service and neither Visited Networks nor wiretappers can get the information of the user’s real identity,which guarantees the confidentiality of information of the user’s identity and location.This protocol can achieve intended service in an efficient and practical way.更多还原
