Abstract(in English) | Side-channel attack using information leakage such as power consumption, electro-magnetic radiation and operation time becomes a large threat. This paper estimates the tamper-resistance of AES module using the simulation method. Logic-gate State-transition times corresponding to a power consumption of CMOS logic circuits is counted by a constant interval time and correlation factor between the transition times and a humming distance of register is calculated. Some results of the simulation show that small interval time leads to a decline of the accuracy of sub-key estimation. This means that high-spec equipment for measuring power consumption of LSI does not always need in CPA attack. It is difficult to modify ASIC circuits after manufacturing ASIC chips, therefore estimating tamper resistance in designing circuits based on simulation method is effective for ASICs. |
