What Iâm worrying about is the following:
My encrypted traffic is stored at the tapped IX, say the NSA does
that. The NSA also observes the traffic from the Tor exit to the US
As pointed out in the FAQ , Tor fails now, as they may perform a
correlation analysis to figure out that the connection to the US
server was coming from me.
(As Mike Perry pointed out : The Raccoon showed that such
correlation suffers from the base rate fallacy. Thus, correlation
might not be as simple as suggested by the FAQ and assumed in
several papers. He also pointed to other attacks into which I did
not look yet.)
