【講 題】Tor and censorship: lessons learned / Tor 與網路審查制度間的微妙關係
【主講人】Roger Dingledine
Roger Dingledine is project leader for The Tor Project, a US non-profit
working on anonymity research and development for such diverse organi-
zations as the US Navy and the Electronic Frontier Foundation. In addition
to all the hats he wears for Tor, Roger organizes academic conferences on
anonymity, speaks at a wide variety of industry and hacker conferences, and
also does tutorials on anonymity for national and foreign law enforcement.

【議程簡介】
Tor is a free-software anonymizing network that helps people around the
world use the Internet in safety. Tor's 1800 volunteer relays 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, and soldiers and aid
workers in the Middle East who need to contact their home servers without
fear of physical harm. Tor was originally designed as a civil liberties
tool for people in the West. But if governments can block connections to
the Tor network, who cares that it provides great anonymity? A few years
ago we started adapting Tor to be more robust in countries like China. We
streamlined its network communications to look more like ordinary SSL, and
we introduced "bridge relays" that are harder for an attacker to find and
block than Tor's public relays. In the aftermath of the Iranian elections
in June 2009, and then the periodic blockings in China, we've learned a
lot about how circumvention tools work in reality for activists in tough
situations. I'll give an overview of the Tor architecture, and summarize
the variety of people who use it and what security it provides. Then we'll
focus on the use of tools like Tor in countries like Iran and China: why
anonymity is important for circumvention, why transparency in design and
operation is critical for trust, the role of popular media in helping --
and harming -- the effectiveness of the tools, and tradeoffs between
usability and security. After describing Tor's strategy for secure
circumvention (what we thought would work), I'll talk about how the arms
race actually seems to be going in practice.
