The Datagram Onion Router

After having a quite depressing discussion about how Tor will evolve in Germany considering the data retention laws, I met a guy on IRC who told me about his new really cool project.

Camilo Viecco, who’s just doing his PhD in CS at the Indiana University, developed a naive UDP-implementation of the anonymisation-principle known as onion-routing from scratch. It’s far from perfect and it wouldn’t meld with the Tor-code easily, but it’s a first approach to improve latency for anon-services.

Tdor is an anonymisation-software to be installed on your local PC. It enables you to use the internet anonymously by configuring tdor as a proxy in your webbrowser. By using this software, no one can find out your IP-address, effectively resulting in an obfuscation of your identity.

The software is available on his homepage and is currently compiling on unixish systems.

What’s different about this project compared to regular anonymisation-systems is that tdor is using UDP instead of TCP, dramatically improving the well-known latency you suffer off when you’re using regular TCP-based anon-systems.

The project didn’t even release it’s first alpha-version, but the version I tested was usable and quite fast. I couldn’t make a difference of regular internet-connections and Internet over tdor.

Though where’s light, there’re shadows: The whole tdor-network only uses six nodes at the moment. It’s not meant to be used for real productive use, it’s only for testing – though it works cool!

At the moment the whole project consists of just a handful of people, but I bet Camilo appreciates any help he can get.

So. If you wanna participate in a really cool fancy brand-new cutting-edge anonymisation technology, grab the sources, compile it, run it and report bugs and issues!
