Abstract:

We develop large network graphs that capture the live Tor network’s autonomous system boundaries, points-of-presence, inter-relay latencies and relay performance characteristics. Using our network models, we evaluate a series of proposed relay selection strategies under various network conditions.  We additionally quantify the anonymity properties of each approach using simulations driven by data from the live Tor network.
