我们描述了Pearson的χ2检验如何用作韦尔奇t检测的天然完成，尤其是泄漏检测。基于Welch的T检验的现有检测技术的基于性质（例如，用于评估噪声不足的高阶蒙版实现）。为了分析阈值实现，信息在多个统计时刻，可以很容易地扩展到杰出者以进行关键恢复攻击，我们相信拟议的测试和方法是侧通道评估工具箱的有趣的完整成分盒子泄漏检测和非核对攻击，并作为初步攻击，然后再进行更高的高级分析。
We describe how Pearson’s χ2-test can be used as a natural complement to Welch’s t-test for black box leakage detection. In particular, we show that by using these two tests in combination, we can mitigate some of the limitations due to the moment-based nature of existing detection techniques based on Welch’s t-test (e.g., for the evaluation of higher-order masked implementations with insufficient noise). We also show that Pearson’s χ2-test is naturally suited to analyze threshold implementations with information lying in multiple statistical moments, and can be easily extended to a distinguisher for key recovery attacks. As a result, we believe the proposed test and methodology are interesting complementary ingredients of the side-channel evaluation toolbox, for black box leakage detection and non-profiled attacks, and as a preliminary before more demanding advanced analyses.
