Re: Re[2]: Can governments block tor?

Secret rendezvous addresses for tor dir servers aren't necessary. In China, for example, all network traffic goes through government-owned firewalls and routers, just like the traffic at your workplace goes through company-owned routers and firewalls. The traffic can be sniffed and logged without blocking it. That way they know who's using tor. It's probably valuable to know who's trying to be a dissedent and what it is they think they're discussing privately.

As for a protocol to keep that hidden, SSL comes to mind. Personally, though, I don't believe you can ever be truly anonymous or secret, so I act accordingly.

Is  there a protocol to keep that hidden? I have a hard time imagining
secret  rendezvous addresses for dir servers for tor, without actually
using tor.
