Performing a comprehensive side-channel analysis evaluation of small embedded devices is a process known for its variability and complexity. In real-world experimental setups, the results are largely influenced by a huge amount of parameters, some of which are not easily adjusted without trial and error and are heavily relying on the experience of professional security analysts. In this article, we advocate the usage of an existing statistical methodology called Six Sigma (6 ) for side-channel analysis optimization. This well-known methodology is commonly used in other industrial fields, such as production and quality engineering, to reduce the variability of industrial processes. We propose a customized Six Sigma methodology, which allows even a less-experienced security analysis to select optimal values for the different variables that are critical for the side-channel analysis procedure. Moreover, we show how our methodology helps in improving different phases in the side-channel analysis process.

侧信道分析的不确定性：一种利用启发式的方法

对小型嵌入式设备执行全面的边信道分析评估是一个以其可变性和复杂性而闻名的过程。在现实世界的实验设置中，结果在很大程度上受到大量参数的影响，其中一些参数在未经反复试验的情况下不容易调整，并且严重依赖专业安全分析师的经验。在本文中，我们提倡使用现有的统计方法，称为六西格玛（6 ) 用于边信道分析优化。这种众所周知的方法通常用于其他工业领域，例如生产和质量工程，以减少工业过程的可变性。我们提出了一种定制的六西格码方法，即使是经验不足的安全分析也可以为对侧信道分析过程至关重要的不同变量选择最佳值。此外，我们展示了我们的方法如何帮助改进边信道分析过程中的不同阶段。
