On the Security of a Three-Party-Authenticated Key Agreement Scheme based on Chaotic Maps
Abstract
Recently, Lee et al. proposed a new three-party-authenticated key agreement scheme based on chaotic maps without password table. Compared with previous works, their scheme can completely resistant to password guessing attacks because of using no passwords. In this paper, we demonstrate that this scheme is still insecure against a user impersonation attack.
