功耗分析攻击中滤噪方法的研究

Research on Filtering Noise Method of the Power Analysis Attack

在真实环境的功耗分析攻击中发现,功耗曲线经常受到大量噪声的影响.为了提高攻击效率,分析了几种常用滤波方法的特点,针对具体的功耗分析问题在真实环境下进行了实验.对几种滤波效果进行了对比,得出滑动平均滤波最适合解决此类问题的结论.

The power consumption curves were often affected by plenty of noise in real environment attack. In order to improve the efficiency of the attack, this paper analyses characteristics of several common filtering noise methods and completes experiments to the specific questions. At last, it compares the filtering effects and draws a conclusion that moving average filter is the most suitable method to solve this kind of problem.
