<h2>Tor: Research</h2>
<hr />

<p>Read <a
href="http://freehaven.net/anonbib/topic.html#Anonymous_20communication">these
papers</a> (especially the ones in boxes) to get up to speed on anonymous
communication systems.</p>

<p>We need people to attack the system, quantify defenses, etc. For example:
</p>
<ul>
<li>Website volume fingerprinting attacks (<a
href="http://freehaven.net/anonbib/#back01">Back et al</a>, <a
href="http://freehaven.net/anonbib/#hintz02">Hintz</a>).
Defenses include a large cell size, <a
href="http://freehaven.net/anonbib/#timing-fc2004">defensive dropping</a>,
etc. How well does each approach work?</li>
<li>The end-to-end traffic confirmation attack. We need to study
long-range dummies more, along with traffic shaping. How much traffic
of what sort of distribution is needed before the adversary is confident
he has won?</li>
<li>It's not that hard to DoS Tor servers or dirservers. Are puzzles
the right answer? What other practical approaches are there?</li>
<li>What sensitive info squeaks by privoxy? Are other html scrubbers
better?</li>
</ul>
