The authenticated multiple-key agreement protocol provides two entities to authenticate each other and establish multiple common keys in a two-pass interaction, a protocol without using a conventional hash function simplifies its security assumption on only public hard problem. In 2004, Chien and Jan proposed an authenticated multiple-key agreement protocol to overcome the shortcomings that break the previous variants. This paper shows that Chien and Jan's scheme has a weakness that is vulnerable to forgery. To remedy this weakness, we improve Chien and Jan's scheme such that the newly improved scheme has authenticated property and does not significantly affect the efficiency of the original scheme. Compared to the previous schemes, our improved method also achieves better key utilization. © Springer-Verlag Berlin Heidelberg 2005.
