Video Presentation by Roger Dingledine

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/

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.

Onion routing application Tor makes PCWorld's top 100

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.
