Abstract：Differential Power Analysis (DPA) attack is the most efficient attack to encryption device. Some existing DPA methods have high demands for differential information and their stabilities are not strong. In this paper based on the analysis of DPA, the authors reconstructed the model of DPA, which reduced the complexity of attack. A new DPA attack combining new power model based on algebraic expression was proposed, and the experimental results show that the proposed DPA attack has the advantages of increasing the correctness of attacking without increasing the time complexity and reducing the number of the needed differential information from thousands to hundreds compared with the existing method.
