Abstract

In 1998, Chang and Wu proposed a group-oriented authentication mechanism with key exchange [Computer Communications21 (1998) 485-497]. The authors show that the Chang-Wu protocols are vulnerable to the impersonation attack. They also give improvements that can not only eliminate the security flaw, but also reduce the redundant messages inherent in the original protocols.
