ill really try not to go conspiracy crazy... but that is always a risk when discussing the NSA on this list :)
if they intercepted everything, there wont be much of a need to decrypt it. they could watch it going in plaintext <tls or hidden services traffic excluded> to the exit nodes, and use timing attacks and get a pretty good sense of where its headed. its not easy, and i cant claim they can actually do that, but thats the risk, and its out of the scope of the Tor threat model. there is a video somewhere of bill binney talking about this approach... somewhere being youtube, but i cant look for it now. a second guess would be going after 1024 bit keys. there is also a video on youtube from a recent con about the feasibility of factoring them, <"fast hacks" or something like that> at the end, jacob applebaum asks about it and they advise him to use longer keys or elliptic curves crypto. exciting times :) if you think im wrong, abuse is welcomed, constructive abuse that is :) On 04/04/2013 06:38 AM, cmeclax wrote: http://www.wired.com/threatlevel/2012/03/ff_nsadatacenter/all/1 If the NSA intercepted all Tor traffic, how fast could they decrypt it? What are they up against when trying to break Tor? _______________________________________________ tor-talk mailing listtor-talk@lists.torproject.orghttps://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk _______________________________________________ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
