摘　　要：为解决AES密码芯片的相关性能量攻击(CPA)的攻击点选择问题,提出了一种CPA攻击点的选择方法,搭建了验证CPA攻击点有效性的仿真平台,并针对AES密码芯片进行了选择分析和验证实验。针对AES密码芯片提出了两种CPA攻击点选择——异或(XOR)操作攻击点和S盒(Sbox)操作攻击点。验证结果表明,两种选择都有效,其中后者的效果更好。To solve the problem on the selection of the attack point of Correlation Power Analysis （CPA） against cryptographic chip of AES, this paper proposes one method for selecting the CPA attack point, and constructs a simulation platform to confirm the validity of the CPA attack point. Combined with AES algorithm, two selections of the CPA attack point, the attack point of the key XOR and the attack point of S-box are proposed, an experiment based on the platform is performed. The result shows that, the two selections of the CPA attack point are valid, and the second one is more powerful.
