我们描述了在泄漏样本分布的任何统计时刻(或其他属性)中执行泄漏评估计算繁重部分的快速技术。提出的技术在数量级上优于Schneider和Moradi在CHES 2015上提出的方法。我们可以在4个cpu小时内执行以前需要90个cpu天的评估(大约500倍的速度提升)。另外,我们可以使用精确的算法,我们可以应用基于核的密度估计方法,我们可以使用任意的预处理函数,如对电源走线的绝对值,我们可以进行信息论的泄漏评估。我们的技巧是简单而优雅的,并且适合于简单而紧凑的实现。我们用大约130行C代码实现了一个原型。
We describe a fast technique for performing the computationally heavy part of leakage assessment, in any statistical moment (or other property) of the leakage samples distributions. The proposed technique outperforms by orders of magnitude the approach presented at CHES 2015 by Schneider and Moradi. We can carry out evaluations that before took 90 CPU-days in 4 CPU-hours (about a 500-fold speed-up). As a bonus, we can work with exact arithmetic, we can apply kernel-based density estimation methods, we can employ arbitrary pre-processing functions such as absolute value to power traces, and we can perform information-theoretic leakage assessment. Our trick is simple and elegant, and lends itself to an easy and compact implementation. We fit a prototype implementation in about 130 lines of C code.
