Abstract (in Japanese) (See Japanese page) 
(in English) There is a risk that crytopgraphic keys can be disclosed from hardware implementations of cryptography such as AES by side-channel attacks(SCA). Since power supply noise can be attenuated in the side-channel information leakage path from the leakage source inside the IC to the point, the design of the leakage path, as well as the leakage source, is important for SCA countermeasures. In the past，the authors simulated power supply noise and SCA results using leakage path design information in order to realize SCA countermeasure design. In addition, the target reduction in simulated power supply noise from the target value of the correlation coefficient, the correlated power analysis by designing the leakage path. In this paper, the target value of the correlation coefficient is set using the theoretical equation for attack success rate, and the target reduction of power supply noise is calculated from the target using the conditional equation. The proposed method was then evaluated on an unprotected AES circuit implemented in an FPGA. As a result, the attack success rate requirement was satisfied.
