Secure authentication process in smart cards

Abstract

The application of smart cards and its fraudulent manipulation by software, hardware or telecommunication appears to be a major concern. Security breaches of smart cards, hacking into the system and creating duplicates of the cards have to be rectified. In this paper we propose an approach to design a more secure two-level authentication process that uses the PIN number as the first level of authentication and OTP generated using SHA-256 as the second level of authentication. Also comparison of various Hash algorithms are performed to justify the use of SHA-256 for OTP generation.
