| Abstract(in English) | Countermeasures for AES software implementation against power analysis attacks are proposed in this paper. Intermediate value is masked random number and Sbox is masked a fixed number "0xFF". Without a use of andom number, Sbox need not be reconstructed. CPA against AES software with the proposed countermeasures could not find out partial keys even using 100,000 waveforms. The proposed countermeasures have also a tolerance against higher order DPA with 8 times of masks using different fixed numbers from 0x01 to 0x80. |
