A New Remote Mutual Authentication Scheme for WI-FI Enabledhand-Held Devices

TLDR: This paper proposes a new remote mutual authentication scheme in wireless environment without maintaining the password table based on ElGamal’s, which provides high security and mutual authentication at a reasonable computational cost.

Abstract: User authentication is a continual problem, particularly with mobile and handheld devices such as Personal Digital Assistants (PDAs), Smartcard, Laptops User authentication is a difficult for every system providing safe access to precious, private information, or personalized services User authentication is the primary line of defence for a handheld device that comes into the hands of an unauthorized individual Password or Personal Identification Number (PIN) based authentication is the leading mechanism for verifying the identity of actual device users Remote mutual authentication is the best solution for remote accessing in Wi-Fi environment In this paper we propose a new remote mutual authentication scheme in wireless environment 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
