After the analysis of the working principle of WAPI, its security weaknesses are pointed out: it does not securely realize the goal of identity authentication and key agreement. According to the security weaknesses, the key agreement part is improved without changing the framework of WAPI. The improved protocol is not only SK-secure but also UC-secure, thus realizing identity authentication and key agreement organically.
