Abstract: This paper presents a novel and efficient implementation the masked advanced encryption standard (AES) S-box on smart card. The proposed scheme has advantages of easy software implementation and lower memory requirement compared to conventional existing implementations. The experimental results and also the results of Welch's T-test statistical analysis demonstrate that the proposed scheme has less information leakage than the conventional first-order masking routines. The target device for evaluating the efficiency of the proposed countermeasure is the smart card of side channel attack standard evaluation board (SASEBO). However, the proposed implementation can be used for other typical platforms, as well.
