摘要
针对差分功耗分析(DPA)攻击的原理及特点,分析了未对齐信号对DPA攻击的影响.论述了现在已知的对未对齐信号的频域和模式识别处理方法,分别分析了它们的原理及优缺点,提出了在时域内对未对齐信号采用分段处理进行对齐的方法.通过实验验证了该方法的正确性及有效性,该方法能够有效的处理未对称信号,提高DPA攻击的效率,减少DPA攻击的样本量.
This paper firstly declares the principle of the differential power analysis attack （DPA） technology, and shows the affects when power analysis in attacking the misaligrnment signs. Then, it analyzes the two methods for the question about misalignment signs. Thirdly, it gets the method about subsection for signs to align the signs. Finally, with experiment, it proves this method can lead to the success of differential power analysis, and it can reduce the amounts of samples.
