Weakness of Several Identity-based Tripartite Authenticated Key Agreement Protocols
Xi-Jun Lin and Lin Sun
Abstract: Key agreement allows multi-parties exchanging public information to create a common secret key that is known only to those entities over an insecure network. In recent years, several identity-based authenticated key agreement protocols have been proposed. In this study, we analyze three identity-based tripartite authenticated key agreement protocols.
After the analysis, we found that these protocols do not possess the desirable security attributes.
