<p>My interest is in designing Open Entropy sources that can be used to circumvent the true random number generators’ great dilemma:-</p>

<p>By using commonly available components like Zener diodes and cameras. These can then be the foundations of your own TRNGs, which you can rely on to not have been compromised by governments/agencies/bad design.</p>
<p>Devices such as:-</p>

<p>Some of which are permanently on-line @ <a href="http://www.reallyreallyrandom.com" rel="nofollow noreferrer">http://www.reallyreallyrandom.com</a> .</p>
<p>Also, now the home of <code>ent3000</code>, a new randomness testing suite for TRNG Makers generating in the sub 1 MB space. Successor to John Walker’s venerable <code>ent</code>.</p>
