摘　　要：主要研究随机密钥协商问题,针对Diffie-Hellman协议、SAKA协议和改进Lin协议、E-SAKA协议等存在的不具有认证功能和不能抵抗中间人攻击等缺陷,应用动态双向认证因子认证方法和非时间同步技术提出一种随机密钥协商协议,该协议适用于OTP动态口令系统设计,同时解决密钥协商过程中的动态认证和时间同步问题。最后,在标准模型下证明了方案的安全性。The random key agreement issue is studied. Since the Diffie-Hellman protocol,SAKA protocol,improved Lin protocol and E-SAKA protocol don′t have the authentication function,and can′t resist the man-in-the-middle attack,a random key agreement protocol is proposed on the basis of the factor authentication method of dynamic bidirectional authentication and non-time synchronization technology,which is suitable for the design of OTP dynamic password system,and can solve the problems of dynamic authentication and time synchronization in the key agreement process. The security of the proposed scheme is proved with the standard model.
