No Tor is not a Chaum-style network. It is an onion routing network not a mix network (See "Why I'm not an Entropist" http://www.syverson.org/entropist-final.pdf) And in particular, it is not as secure as the security provided it its strongest, most honest node in a circuit. End-to-end correlation works just fine even if everything betweent eh entry and exit relasys is honest and well performing. (See "Users Get Routed: Traffic Correlation on Tor by Realistic Adversaries" http://www.ohmygodel.com/publications/usersrouted-ccs13.pdf. The last comment of the paragraph is correct however. aloha, Paul -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
