提出了一种具有身份验证的密钥协商方案,并证明了其安全性。该方案的特点是:(1)在离散对数问题难解的假设前提下。可抵抗被动攻击和主动攻击;(2)身份验证与密钥协商紧密结合;(3)认证服务中心负责签发证书,但不直接参与身份验证和密钥协商过程;(4)只需要两次模指数运算。
A key agreement scheme with identity authentication is proposed and its security is proved. The program is characterized by: (1) Under the premise of the intractable discrete logarithm problem. Can resist passive attacks and active attacks; (2) authentication and key agreement are closely integrated; (3) certification service center is responsible for issuing certificates, but not directly involved in authentication and key agreement process; (4) Index calculation.
