Hi, I just had an idea, how an attacker could slow down the Tor network, and wanted it to discuss with you. To my knowledge, there is only the BadExit and BadDirectory flag, nothing like BadNode. In contrast to a bad exit, which is misbehaving, how could the network block a node, which has all outgoing traffic blocked? Lets say, I set up some (few hundred or so) Nodes, which I start up and then block outgoing traffic on them. If they're chosen as middle node for a circuit, the circuit can't build, because the next server cannot be reached. If my servers advertise a high bandwidth (is there any detection for false bandwidth advertisings?), Tor will often try to put them in a circuit, and often will fail. This could lead to no usable circuit for several minutes.
Let me know what you think! Thanks :) -- morphium - [email protected] - 113332157 http://identi.ca/morphium - http://twitter.com/morphium86 _______________________________________________ tor-talk mailing list [email protected] https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
