【摘要】针对目前针功耗分析攻击的影响因素研究偏少的情况,讨论和分析了取样电阻对功耗分析攻击的影响.功耗分析攻击的研究对象是功耗曲线,现有常见实验平台采集的通常是包括各种噪声的功耗综合.取样电阻作为功耗分析平台中的一部分,会在电阻噪声和功耗区分度两方面造成影响,进而影响到功耗分析攻击的正确率.因此为了提高攻击正确率,在不影响区分度的前提下可选用相对小的电阻.?cording to the current situation that the research of the influence factors of power analysis attack is less than expected, this paper discusses and analyzes the impacts of the sampling resistance of power analysis attack. The study object of power analysis attack is power curves, and the data collected in present popular experimental platforms is power consumption concluding much noise. The sampling resistance as part of the power analysis platform will influence the power analysis attack in resistance noise and power discrimination two sides, and further affect the accuracy rate of power consumption analysis attack. So, on the premise of discrimination, the increased accuracy rate will be achieved by choosing the smaller resistance. 【总页数】4页(364-367)
