Cryptanalysis of an Authentication Key Exchange Protocol

Chou-Chan Yang, Ya-Wen Yang and Ting-Yi Chang

Abstract:
An authenticated multiple-key agreement protocol uses a digital signature to sign the Diffie-Hellman public keys which can generate multiple session key in a single round of message exchange and achieve mutual authentication. Recently, Hwang et al. proposed an authentication key exchange protocol which takes less computation time than Harn and Lin;s protocol. However, this study, shows that Hwang et al.`s protocol is vulnerable to forgery attacks. An attacker can fool one communication part into believing the forged short-term public keys and share session keys with him.
