Password based remote authentication scheme using ECC for smart card

Abstract

Remote user authentication is a continual problem, particularly with mobile and handheld devices such as Personal Digital Assistants (PDAs), Smartcard, Laptops. Providing user authentication for safe access of precious, private information, or personalized services, for every system is difficult User authentication is the primary line of defence for a handheld device that falls 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 authentication is the best solution for remote accessing in smart card environment. In this paper we propose a Password based authentication scheme using ECC for smart card environment, without maintaining the password table by the server. It provides high security 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.
