Abstract:
Password based authentication schemes are commonly used to authenticate remote users. Many schemes have been proposed both with and without smart cards but each have its own merits and demerits. This paper analyzes the security of an enhanced Dynamic ID based remote user authentication scheme and shows that the enhanced scheme has major security weaknesses. The paper also presents a new scheme which overcomes the weaknesses and provides better security strength.
