In this paper, the authors present a highly secured ATM banking system using an optimized Advanced Encryption Standard (AES) algorithm. Two levels of security are provided in this proposed design. They consider the security level at the client side by providing biometric authentication scheme along with a password of 4-digit long. Biometric authentication is achieved by considering the fingerprint image of the client. They ensure a secured communication link between the client machine to the bank server using an optimized energy efficient AES processor.
