摘　　要：针对异构无线网络中的认证协议的安全问题,提出一种基于CPK算法和改进的ECDH算法的双向认证和密钥协商协议,引入用户的临时认证身份和临时通信身份实现用户的身份匿名;提出采用临时通信身份有序对防止重认证过程中的重放攻击,并且在协议设计中规避了密钥泄漏带来的风险。分析表明该协议具有身份认证、会话密钥安全、匿名性等安全属性。Aiming at the security of authentication protocol for heterogeneous wireless network, a mutual authentication and key agreement protocol, which was based on CPK algorithm and improved ECDH algorithm, was proposed. The temporary authentication identity and temporary communication identity was adopted to realize user identity anonymity. The ordered pair of temporary communication identity was proposed to prevent replay attack in the process of re-authentication. The risk of key compromise was also avoided in the proposed protocol. By security analysis, this protocol had the security properties such as identity authentication, key security and anonymity.
