| Abstract(in English) | AES is one of the common key cryptosystems often used on an embedded systems, IC-chips and others. Teir common key must be kept secret from others. However, it can be deciphered by side channel attack, the method of cracking cryptosystems by analyzing physical quantity generated at the encryption processing. Especially in side channel attack, differential power analysis (DPA) is known as the most dangerous attacking method. AES circuit is needed to be designd with regard to anti-DPA. To design an anti-DPA AES circuit, we propose a power masking SubBytes circuit which switches several S-Boxes, each of which has a different power to each other. We demonstrate our evaluation and results. |
