<h1>USB TRNG</h1>
<p>Yesterday I had a blast presenting my talk
<a href="https://summit.debconf.org/debconf14/meeting/20/security-not-by-chance-the-altusmetrum-hardware-true-random-number-generator/">Security not by chance: the AltusMetrum hardware true random number generator</a> at <a href="http://debconf14.debconf.org/">DebConf14</a>.</p>

<p><a href="http://altusmetrum.org/USBtrng/">USB TRNG</a> is a collaborative effort with <a href="http://altusmetrum.org/">AltusMetrum</a>
to create a completely open hardware and Free software true
random number generator.</p>
<p>In my talk I mention the rationale for gathering more entropy:
<em>The Linux urandom boot-time entropy hole</em> as described in
the paper
<a href="https://factorable.net/weakkeys12.extended.pdf">Mining Your Ps and Qs: Detection of Widespread Weak Keys in Network Devices</a>.</p>
<p>I also mention some of the difficulty in assessing RNG
quality for security applications as highlighted by
Matthew Green in his blog post
<a href="http://blog.cryptographyengineering.com/2014/03/how-do-you-know-if-rng-is-working.html">How do you know if an RNG is working?</a>.</p>
<p>I've been lucky to work on this design with <a href="http://gag.com/bdale">Bdale Garbee</a>
and <a href="http://keithp.com/keithp">Keith Packard</a>.</p>
