| Abstract(in English) | There are a lot of studies about side channel attacks against cryptographic device which details of implementation are unknown. However, it is thought that the attack becomes a stronger attack if details of implementation are known. We studied an efficient method of acquiring information that depends on typical block cipher implementation on CPU board, and report on the attack experiment based on data that measures CPU board. Using information acquired from CPU board, we succeeded in this attack at the probability of 90% if there are two measurement data, and the probability of 65% if there is one measurement data. |
