That's why the Dresden-Dresden cascade | is so popular, despite it's principal problem. A couple of comments, which I'll then connect. Performance was the number one complaint about Zero-Knowledge's Freedom network. There is no exponential term in MIX traffic. That means that if you try to ensure that all traffic leaves the network quickly (so you can say, web browse), then your attacker only needs to analyze traffic over a few seconds, and that's easy. Simple attacks work really well on real time mix chains of any length that TCP timeouts are likely to allow. As such, I'm actually very suprised that the German police bothered with this compelled back door stuff. Perhaps they failed to talk to their national technical experts, or their experts failed to tell them how easy traffic analysis is for them. Is there a political motive? Are we about to see legal attacks on high latency mixes?
