Verification of a side channel takes a very long time because of an amount of data and the number of analyzing candidate keys. When an equipment manufacturer verifies safety of equipment of the company or an evaluation institution receives a request of safety verification of the equipment and evaluates the equipment, since a key of the equipment is previously known, an entire verification time may be reduced by using the key. According to the present invention, the verification is divided into two steps where, in the first step, the number of candidate keys is reduced to perform the verification and, in the second step, a size of a waveform is reduced to perform the verification, so that the entire verification time can be reduced. |
