Gaoli Wang · Journal of Nanjing University of Posts and Telecommunications · 2010
Anonymous password-authenticated key exchange(APAKE)protocol can provide both password-only authentication and user anonymity over a public network.Following an analysis of the security problems pertaining to an efficient APAKE protocol,a new efficient secure APAKE protocol is proposed.The analysis shows that the proposed protocol is resistant to dictionary attack and provides user anonymity.The server and the user need 2 modular exponentiations respectively.Compared to the existing APAKE protocols,the efficiency has been improved substantially.
