A side channel attack by means of electromagnetic analysis for SASEBO-AES was investigated. Local information from FPGA mounted on SASEBO-AES was observed using a commercial magnetic probe which has spatial resolution of 250 micro meter. We also found that negative and minimum correlation factor was obtained, and indicated correct key byte in some of point of measurement. Our results show that, in electromagnetic analysis, not only maximum values but also negatives should be taken account for estimation of encryption key. |
