NSA doesn't need to run exit nodes, they just need correlate packet flows from exit nodes with packet flows to entry nodes. It's easy if you have both flows (say by taping most fiber lines). Tor doesn't protect you against a global passive adversary. That is the price you pay for low latency.
- einhverfr 13y agoBut if you run entrance nodes on your intranet, then they have to compromise your endpoint right? But if they compromise that then they don't need to correlate with timing attacks, do they?
- mortehu 13y ago> say by [tapping] most fiber lines You realize there are tens of thousands fiber lines in a city, right? Tapping fibers going from ISP cusomers to PoPs isn't scalable. Hiding the equipment from the people working every day on splicing smaller fiber cables to the trunks would also be a major issue.
- anologwintermut 13y agoSorry, most fiber lines is absurd, I should have said they could intercept most of the world's traffic by taping key fiber lines. Say, most of the major underseas ones and any of the major ones traversing the five eyes (US,UK,CA,AU,NZ) + at least Sweden and probably a number of other countries.
