| Abstract(in English) | In 2002, Tsunoo et al. proposed a cache attack using fluctuation of encryption times of a software implemented on CPU with cache. Cash attack, proposed by Tsunoo et al. in 2002, is a side channel attack which can be applied to encryption software having S-boxes implemented as tables. It utilizes the perturbation of encryption time as side information for the attack. In this paper, we analyzed the performance of Cash attack based on Average encryption time method. By a theoretical analysis, we derived the necessary number of encryption as a function of S-box entry size and the number of S-boxes used in the encryption algorithm. The estimated number is compared to the experimental results. |
