Chaotic map has been receiving more and more attention in the cryptographic literature. In recent years, there are some scholars working on a particular type of authenticated key exchange protocol using chaotic map. Some of them identified a vulnerability of their precedences and presented their patching protocols. In this paper, we also identify a vulnerability in some of these authenticated key exchange protocols. We first redesign a protocol and optimize it in computation efficiency. Then we present the security analysis by a logic proof based on BAN logic.
