Abstract :
Remote authentication schemes with smart cards have gained much attention in recent years. Recently Lee and Chiu proposed an improved remote authentication scheme with smart cards. It enables the user to freely choose his password and claim that their scheme is secure. Nevertheless, we present attacks and weaknesses of the scheme. Additionally, we propose a new improved scheme to counter these attacks.
