摘　　要：当前智能卡的涌现为人们生活增添了很多方便,但是它在使用过程中会存在信息泄漏的问题,对智能卡系统的安全建设造成很大的威胁。为了提高智能卡系统的安全性和可靠性,采用侧信道攻击方法之一的差分能量分析攻击(DPA)来改善性能。文章采用基于AES算法的能量分析攻击方法对智能卡系统进行分析研究,通过分析密码设备的能量消耗,实时记录密码设备对大量不同数据分组进行加密或者解密操作时的能量迹的方法来获得密钥,并通过使用AES算法对DPA攻击进行深入分析,从而有效的揭示出智能卡中的信息,结果表明,基于AES算法的DPA攻击可以有效的揭示智能卡的密钥信息。The emergence of the current smart card has added a lot of convenience to people’s lives, but it will have the problem of information leakage during its use, which poses a great threat to the security construction of the smart card system. In order to improve the security and reliability of the smart card system, differential energy analysis attack(DPA), one of the side channel attack methods, is used to improve performance. The article uses an energy analysis attack method based on the AES algorithm to analyze and study the smart card system. By analyzing the energy consumption of the cryptographic device, the method of real-time recording the energy trace when the cryptographic device encrypts or decrypts a large number of different data packets is used to obtain the key. And through the use of the AES algorithm to conduct an in-depth analysis of the DPA attack, thereby effectively revealing the information in the smart card, the results show that the DPA attack based on the AES algorithm can effectively reveal the key information of the smart card.
