Research problem: measuring the anonymity of the Tor network
- xtacy 16y agoTor is decentralised, but not distributed. How would Tor compare to a p2p anonymising service? Example: https://home.zhaw.ch/~rema/projects/morphmix/ https://home.zhaw.ch/~rema/projects/morphmix/
- ohmygodel 16y agoP2P anonymization is tricky. Making it scalable means that each member of the network isn't aware of every other member, and therefore a small malicious set of peer may be able to "capture" the routes of nodes that only know them or rely on them to boostrap into the network. The most sophisticated current research proposals are probably ShadowWalker by Mittal and Borisov (https://netfiles.uiuc.edu/mittal2/www/shadowwalker-ccs09.pd https://netfiles.uiuc.edu/mittal2/www/shadowwalker-ccs09.pd) and Torsk by McLachlan et al. (www-users.cs.umn.edu/~hopper/torsk-ccs.pdf). They are both certainly less vulnerable than MorphMix, which anyway is designed for high-latency communication.
- frisco 16y agoTor should raise a fund to host a series of $10-20k prizes for deanonymizing Tor users. That would drive a huge amount of attention to the code and build credibility over the long term as prizes are awarded increasingly rarely.
