摘　　要：分析了开放网络环境的认证,指出了综合利用多种密码技术设计认证系统以满足日益复杂认证需求的必要性。通过研究认证与密钥交换机制,分析现有协议特性,权衡认证系统安全性、效率及需求等因素,提出了一种认证与密钥交换协议。协议进行分布式认证,综合利用EC密钥协商和对称密钥传输进行密钥交换,可实现双向身份认证和显式密钥认证。该方案可使认证系统性能提高,需求降低。The authentication in an open network is analyzed.To meet increasingly complex authentication requirements,the necessity of taking advantage of multi-cryptosystem to design authentication system is pointed out.The mechanism of authentication and key exchange is researched,and the characteristics of protocols in existence are analyzed.Based on trade-off among security,efficiency and system requirements,a protocol of authentication and key exchange is put forward.The protocol performs distributed authentication,carries out key exchange through integrated utilizing EC key agreement and symmetric key transport.Mutual authentication and explicit key authentication are finished.The protocol can improve the performance of authentication system,and lower its requirements.
