While it&#x27;s definitely a good idea to run it through something like Diehard, it&#x27;s interesting to note that [this principle has already been the subject of a lot of research](<a href="https:&#x2F;&#x2F;www.kernel.org&#x2F;doc&#x2F;ols&#x2F;2014&#x2F;ols2014-mueller.pdf" rel="nofollow">https:&#x2F;&#x2F;www.kernel.org&#x2F;doc&#x2F;ols&#x2F;2014&#x2F;ols2014-mueller.pdf</a>) (granted, the CPU time jitter uses <i>time</i> noise as an entropy source where the post uses electrical signal noise, but it&#x27;s a fairly similar principle all the same).
