The original energy trace dataset have low signal-to-noise ratio which extremely seriously affects the efficiency of side channel attack. For features in energy analysis attacks, this paper proposes a noise reduction method solving the problem that the traces mainly focus on desynchronization and gaussian noise. By combining the low-pass filtering and the DAE model used in this paper, the energy trace is reduced to achieve a high signal-to-noise ratio and expose the POI position of the leakage point clearly. As the image indicates, this work increases the signal to noise ratio of the noise energy trace by 75.9%.
