A side-channel attack is known as a serious threat which can obtain a secret key by analyzing physical information leakage from cryptographic devices. When we analyze side-channel information to retrieve the key, measurement errors can affect the analysis. The authors analyze an effect of quantization errors on retrieving the key. We performed correlation power analysis(CPA), tuning the resolution of the measurement instrument. Through the experiments, The authors showed that it sometimes become easy to retrieve the key for the reduced resolution. |
