Abstract

Biswas proposed two protocols based on the two-party Diffie-Hellman technique: (1) key agreement with multiple two-party keys and (2) a contributory group key exchange protocol. Then, Tseng and Wu pointed out that the second protocol has a security weakness and proposed a new protocol to remedy the weakness. In this paper, the authors point out that the Biswas's first protocol is vulnerable to a man-in-the-middle attack. Through the attack, an attacker can intercept, modify, or delete the communicated messages between two communicating party or among the group members.
