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.
