| 摘 要： | 为研究高级数据加密标准(AES)针对电磁旁路攻击的脆弱性,分析了微处理器的电磁信息泄漏模型和攻击AES时D函数的选择问题.针对PHILIPS 89C51实现的AES-128密码系统,采用差分电磁分析的方法进行了密码破译实验,成功获得了128位密钥.经分析发现AES的字节替代变换可产生密钥泄露,为密码系统实施相关防护措施提供了依据.

| Abstract: | To study the vulnerability of Advanced Encryption Standard (AES) against electromagnetic side channel attacks,the article analyzed the electromagnetic information leakage model of microcomputer and the choice of D function. Then,concerning the AES-128 bits cryptographic system realized by the 89C51 microchip,Differential Electromagnetic Analysis (DEMA) algorithm,which was used into an attack experiment and succeeded in obtaining 128 bits secret key of AES-128,was described. After analyzing the experimental ... |
