Hi I wanted to bring your attention to this recent Tor attack paper published at the CCS conference:
https://arxiv.org/pdf/1808.07285.pdf > We show that with moderate learning, DeepCorr can correlate Tor > connections (and therefore break its anonymity) with accuracies significantly > higher than existing algorithms, and using substantially shorter lengths of > flow observations. For instance, by collecting only about 900 packets of each > target Tor flow (roughly 900KB of Tor data), DeepCorr provides a flow > correlation accuracy of 96% compared to 4% by the state-of-the-art system of > RAPTOR using the same exact setting. > > We hope that our work demonstrates the escalating threat of flow > correlation attacks on Tor given recent advances in learning algorithms, > calling for the timely deployment of effective countermeasures by the Tor > community. It has an extremely high true positive rate under real world conditions. The two main suggested countermeasures are padding and AS-aware path selection. I think you are working on the former but no practical implementation of the latter is ready? _______________________________________________ tor-dev mailing list tor-dev@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-dev
