摘　　要：将AES算法中S-Box的运算输出作为差分能量分析的中间值,设计基于特征点分布和汉明重量模型的模板构建策略,并以贝叶斯定理优化攻击。该方法可降低计算复杂度和模板数量,实验结果验证了其有效性。This paperfirstly utilizes the output of S-Box operation in the AES algorithmas theintermediate valueof dif erential power analysis,designsthe construction strategy of template based on the characteristicdistributionand Hamming-Weight Model,and then conducts the at ack optimizedby Bayes＇ theorem. The method can greatly reduce the computational complexity and the number of template, and the ef ectivenessof which is demonstrated by the experimental result.
