| Abstract(in English) | In the evaluation of side-channel resistance, it is argued how many observation of physical phenomena which is caused by cipher module are required for revealing secret information. In this argument, evaluator performs actual attack to the cipher module and examines experimentally the number of observation which is required for revealing secret information. Hence, the number examined by this method lacks rationale, and this method affected by some constraints, such as specification of experimental equipment or execution time. Moreover, by this method, we cannot execute mutual evaluation easily. On the other hand, in our approach, we regard the side-channel attack as the communication channel model, and by using Shannon-Hartley theorem, estimate the channel capacity of the model as the upper-bound of the amount of leakage information of the secret information which are got by observation at attacking. In this paper, we apply our approach on the correlation power analysis against some kinds of implementations of the stream cipher Enocoro-128 v2 as an example, and confirmed the effectiveness of our method. |
