We observed and analyzed electromagnetic information leakage of the Advanced Encryption Standard (AES) cryptographic circuit implemented on an FPGA to estimate the root cause of the EM information leakage. Our final goal of this work is to develop an efficient countermeasure at IC cell level for securing cryptographic security from correlation power analysis(CPA), one of the most powerful attack method causing EM information leakages from hardware implementation of cryptography. For this purpose, we examined a simple countermeasure to CPA and investigated the AES implementation for the root cause. We attacked the AES implementation, including the countermeasure, using two power models in the CPA: hamming distance (HD) model and hamming weight (HW) model. We verified that the countermeasure worked in CPA using the HD model expectedly. We also found, in CPA using the HW model, several sub-circuits of the AES implementation leaking side-channel information in detectable level for adversaries. The detectable leakage was not mitigated by the simple countermeasure. |
