【摘要】：常用的基于证书的认证密钥协商协议,在管理和维护证书方面占用较多的资源.在无证书的密钥协商协议的基础之上,综合密钥安全和性能方面的考虑,从可认证密钥协商形式化安全模型分析入手,提出了一种增强的可认证无证书的密钥协商安全模型,给出了可认证无证书密钥协商协议CL-AKA,并从系统建立、用户密钥生成和密钥协商3个方面进行了描述和安全性分析.结果表明,该协议安全性高,与同类协议相比具有性能上的优势.
[Abstract]:The commonly used certificate-based authentication key agreement protocol occupies more resources in the management and maintenance of the certificate. On the basis of the certificate-free key agreement protocol, the key security and performance considerations are integrated. Based on the analysis of formal security model of authenticated key agreement, this paper proposes an enhanced security model of authenticated and non-certificated key agreement, and presents the authenticated non-certificate key agreement protocol (CL-AKAA). Three aspects of user key generation and key agreement are described and analyzed. The results show that the protocol is more secure and has better performance than similar protocols.
