New Remote Mutual Authentication Scheme using Smart Cards

Remote mutual authentication based on smart cards is the best practical solution for remote accessing. Most of the schemes are password based. In this paper we propose a new remote mutual authentication scheme using smart cards without maintaining the password table. This is based on ElGamal's. It provides high security and mutual authentication at a reasonable computational cost. Furthermore it restricts most of the current attacking mechanisms. It is simple and can be adopted in any kind of lightweight devices.
