A cryptographer and network security expert, Roger Dingledine spoke about the TOR Onion Router (TOR) project.
The Electronic Frontier Foundation (EFF) is a nonprofit group working to protect your digital rights. Roger went to MIT and worked for the NSA at one time. http://tor.eff.org/ http://tor.eff.org/overview.html
Tor's technology aims to provide Internet users with protection against "traffic analysis," a form of network surveillance that threatens personal anonymity and privacy, confidential business activities and relationships, and state security.
Roger said he tells his grandparent that he works with communicating privately, he tells his computer community peers that he works with anonymity networks, and the military people hear that he works with traffic analysis resistant communication networks.
The question was posed, "Who needs anonymity?" Different models were discussed including remailers, mixing servers, and proxy servers. Multiple TOR servers replicating encrypted data to hide source and target. Location Hidden Servers were discussed for their strategic benefits.
TOR was a response to a need. Running since October 2003, there are 150 TOR server nodes worldwide with 15,000 users generating over 50,000 hits a day. The bandwidth traffic is 5 to 10 Mbs. Three deep encrypted mixing of traffic. Looks just like a SOCKS proxy to the client. Supports BSD, Mac OS X, Solaris, Windows, and Linux platforms.
Larger social political issues are represented by this project. Privacy and security are needed and in fact are the preferred state of internet user communications. Anonymity is the cornerstone of your right to privacy. Free speech is the ideal and secure private speech is the insurance that this exists.
A big round of applause for Mark Jones who stepped up and put this presentation together. THANKS MARK!!!
The T-Shirt Dingledine is wearing is a parody of a Jack Daniels ad featuring "Jack Florey," a non-existant MIT personality famous for his hacks. Roger is an MIT graduate that worked, at one time, for the National Security Administration (NSA). Roger does security research.
