This paper presents a practical smart card implementation of advanced encryption standard (AES-128) algorithm combined with a simple yet effective masking scheme to protect it against first-order power analysis attacks in both time and frequency domain. The proposed masking method which is a generalisation of the conventional masking method, stores randomly masked S-box data in a masked table in a more efficient way than conventional masking scheme such that each addressed data in the table uses a different random value which makes the actual processed values uncorrelated to power consumption of the device. The proposed implementation has advantage of easy software implementation, low memory and clock cycle requirement. The target device for evaluating the efficiency of the implementation and countermeasure is the smart card of side-channel attack standard evaluation board (SASEBO-W).
