| Abstract(in English) | In this study, EMC-macro modeling was examined to develop a method to evaluate cryptographic systems before fabrication. A EMC-macro model of a cryptographic FPGA in which an AES algorithm had been implemented was determined from experimental measurements under the initial configuration of a power distribution network (PDN) of FPGA. The model was implemented into a commercial analog circuit simulator and side-channel traces due to the SSN current was estimated under three different PDN configurations under which a decoupling circuit was inserted into the PDN as a countermeasure. Estimated side-channel traces were analyzed statistically by the correlation power analysis (CPA) method to obtain correlation values, a major security index of AES. Variation of the correlation values with changes in decoupling configuration agreed with the corresponding experimental results. This means that security of cryptographic devices against side-channel attacks can be evaluated by using the equivalent circuit model before fabrication. |
