What do the United States Department of Defence and the
Electronic Frontier Foundation have in common? They have both funded
the development of Tor (tor.eff.org), a free-software onion routing
network that helps people around the world use the Internet safely.
The public Tor network has 150 servers on five continents, and
averages over 40Mbit/s of traffic. Our users include ordinary
citizens who want protection from identity theft and prying
corporations, corporations who want to look at a competitor's website
in private, and aid workers in the Middle East who need to contact
their home servers without fear of physical harm.
Roger Dingledine give an overview of the Tor architecture, and talk
about why you'd want to use it, what security it provides, and how
user applications interface to it. He show a working Tor network, and
invite the audience to connect to it and use it.
Roger Dingledine is a security and privacy researcher. While at MIT
he developed Free Haven, one of the early peer-to-peer systems that
emphasized resource management while retaining anonymity for its
users. Currently he consults for the Electronic Frontier Foundation
and the U.S. Navy to design and develop systems for anonymity and
traffic analysis resistance. Recent work includes anonymous
publishing and communication systems, traffic analysis resistance,
censorship resistance, attack resistance for decentralized networks,
