摘　　要：为了对RSA密码芯片的DPA攻击进行深入研究,介绍采用相应攻击算法对AT89C52单片机上加密程序进行攻击的过程,设计并搭建了功耗分析测试平台。利用该平台,对单片机实现的8位模拟RSA加密算法进行了SEMD算法差分功耗分析(DPA)攻击实验。实验结果表明:当进行差分的功耗轨迹中对应部分无法准确对齐时,SEMD攻击算法存在失效现象。In order to studying the DPA attack of RSA cipher chip, introduce the attack process on coded program of AT89C52 single chip by corresponding attack algorithm, a power consumption analysis testing platform was designed and constructed. With this platform, SEMD algorithm differential power analysis （DPA） attack experiment against the 8 bit simulated RSA running in a single chip was carried out. In the experiment, SEMD attack algorithm became workless when the corresponding parts in the different power traces can not be arranged.
