摘　　要：为了对RSA密码芯片的DPA攻击进行深入研究,采用相应攻击算法对AT89C52单片机上加密程序进行攻击,设计并搭建功耗分析测试平台。利用该平台,对单片机实现的8位模拟RSA加密算法进行ZEMD算法差分功耗分析(Differential Power Analysis,DPA)攻击实验。实验结果表明,由于明文的随机输入,使得模乘运算的时间消耗会有所不同,导致进行差分的功耗轨迹中对应部分无法准确对齐,ZEMD攻击算法存在失效现象。In order to research on DPA attack of RSA code chip,adopt corresponding attack method to attack encrypt program on AT89C52 single chip,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,ZEMD attack algorithm became workless when the corresponding parts in the different power traces cannot be arranged.The reason of these phenomena was the random input of the plaintext.
