Seo and Sweeney recently proposed a simple authenticated key agreement protocol using a password-based method. They claimed that the established session key between two users is also verified. However, the author points out that verification of the session key cannot be achieved in their protocol. A slight improvement to their protocol is proposed to overcome this weakness.
