Abstract
Correlation Power Analysis (CPA) is an efficient way to recover the secret key of the target device. CPA technique exploits the linear relationship between the power model and the real power consumption of an encryption device. In theory, we only need fewer power traces to recover secret key bytes successfully. However, due to the impact of noise, we need a larger number of power traces in order to extract the secret key. Therefore, the computation time becomes a serious problem for performing this attack. This paper introduces a new method to reduce the computation time for CPA method with the technique of finding points of interest which was used for template attack. The experimental results have clarified the efficiency of the proposed method.
