Tor and blocking-resistance

Presented at DEF CON 15 (2007), Aug. 4, 2007, 2 p.m. (110 minutes)

Websites like Wikipedia and Blogspot are increasingly being blocked by government-level firewalls around the world. Although many people use the Tor anonymity network to get around this censorship, the current Tor network is not designed to withstand a large censor. In this talk I'll describe our plan for extending the Tor design so these users can access the Tor network in a way that is harder to block.

Presenters:

  • Roger Dingledine - Project leader, The Tor Project
    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. He is best known for leading the Tor project, an anonymous communication system for the Internet that has been funded by both the US Navy and the Electronic Frontier Foundation. He organizes academic conferences on anonymity, speaks at such events as Blackhat, Defcon, O'Reilly ETech, Toorcon, 21C3, and What the Hack, and also does tutorials on anonymity for national and foreign law enforcement.
