Abstract:
Now days, sharing data in communication systems and computers require high levels of Information security. Side channel attack is one of the methods which it is applied to attack cryptographic systems such as smart cards. In this paper, a new approach for countermeasuring cryptographic algorithms has been proposed and implemented on FPGA. The scheme is based on using Phase Locked Loop in AES algorithm which by disturbing power consumption pattern and execution time of different rounds, the resistance of the algorithm against power attack has been increased. Masking and hiding technique has been used to protect the encryption key. Overall, the proposed method has been simulated within TSMC 65nm technology platform and outstanding success has been obtained; in applying the technique to AES, the overhead was 13% in CMOS area, 15% in power consumption, 2% decrease in working frequency while finding the key became difficult for attackers. In addition, the proposed method has been implemented on FPGA and satisfactory results have been obtained for an acceptable number of samples of the power trace.
