An Energy Efficient ATM System Using AES Processor

This paper presents a highly secured ATM banking system using an optimized Advanced Encryption Standard (AES) algorithm. Two levels of security are provided in this proposed design. Firstly we 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. Secondly we ensure a secured communication link between the client machines to the bank server using an optimize energy efficient AES processor. The fingerprint image is the data for encryption process and 4-digit long password is the symmetric key for the encryption process. To get a low power consuming ATM machine, an optimized AES algorithm is proposed in this paper. In this system biometric and cryptography techniques are used together for person authentication to improve the security level . The proposed design is secured against all kinds of attacks. The design of the processor is simulated on the FPGA platform. Simulation results ensure its proper functionality. The speed performance of the processor is also analysed and compared with that of other researchers in ASIC technology which also proves its superiority over them.
