| Abstract(in English) | Differential power analysis (DPA) is a kind of side channel attacks which enables attackers to estimate secret information by statistically processing power consumpion of the target device. Because DPA is a powerful attack, it is demanded for designers of cryptograhic devices to evaluate their DPA resistivity. In this paper, we try to make more efficient the evaluation of DPA resistivity by decreasing the number of samples required for the analysis. It was quantitatively shown by simulation that in case of DES, DPA referring to left half of 15th-round outputs requires less number of samples than referring to the 16th-round Sbox outputs. Furthermore, DPA referring to multiple bits requires less number of samples than referring to single bit without changing DPA success rate (implying more powerful DPA attack with the same number of samples). It was also shown that the number of samples could further be reduced by taking a vote among multiple results of DPA. |
