"Tor: Anonymous communications for government agencies, corporations, journalists... and you"
What do the Department of Defense and the Electronic Frontier Foundation have in common? They have both funded the development of Tor (torproject.org), a free-software anonymizing network that helps people around the world use the Internet in safety. Tor's 1500 volunteer servers carry traffic for several hundred thousand users including ordinary citizens who want protection from identity theft and prying corporations, corporations who want to look at a competitor's website in private, law enforcement and government intelligence agencies who need to do operations on the Internet without being noticed, and aid workers in the Middle East who need to contact their home servers without fear of physical harm.
We'll give an overview of the Tor architecture, and talk about why you'd want to use it, what security it provides, and policy and legal issues. Then we can open it up for discussion about open research questions, wider social implications, and other topics the audience wants to consider.

Roger Dingledine is project leader for The Tor Project, a US non-profit working on anonymity research and development. While at MIT he developed Free Haven, one of the early peer-to-peer systems that emphasized resource management while maintaining anonymity for its users. He works with the Electronic Frontier Foundation, the US Navy, Voice of America, and other organizations to design and develop systems for anonymity and traffic analysis resistance. He organizes academic conferences on anonymity, speaks at such events as Blackhat, Defcon, Toorcon, CCC congresses, and What the Hack, and also does tutorials on anonymity for national and foreign law enforcement. Roger was honored in 2006 as one of the top 35 innovators under the age of 35 by Technology Review magazine. http://freehaven.net/~arma/cv.html
