Hi there,
I am currently writing my Master's thesis about Mix networks & Tor (was on list previously). I am currently at a point, where I'd like to practially quantify anonymity. That is, given a pcap, I want to anaylze how successful an adversary can determine whether a specific client talked to a specific service. Since I run all of this in a simulation (using Shadow), I have access to ground truth and can determine the traffic, network size, etc. arbitrarily.
The idea behind all of this is to integrate a Mix relay on each Tor node and to watch how the adversarys success behaves. However, I have a hard time finding material on such attacks, i.e. papers that closely examine this scenario (and perhaps have conducted some simulation and/or measurements themselves, beyond simple theory). The thing is that this is only part of the research and I'd really prefer if I could build this upon work of others instead of starting from scratch.
Do any of you know of such papers or corresponding research?
Regards, Florian
