Abstract :
Recently, Han-Chang proposed a flexible chaotic key agreement protocol based on nonce. In this paper, we demonstrate that it is vulnerable to spoofing attack and replaying attack. Furthermore, a secure improvement is suggested, which avoids the flaws while keeping all the merits of the original scheme.
