Re[2]: [rishab@dxm.org: Re: [silk] inside the Great FireWall...]

The  idea  is that the circuit coordination is distributed among three
layers.  The  first  tier  recieves  info  from  the Tor server saying
"hello,  I'm alive. Add me to the ultimate list". The second tier gets
regional  lists from the first tier, so nobody but tier 1 has a global
view. The third tier is the one that gets a request from the tor user,
specifying what kind of circuits it wants (fastest, country avoidance,
specific  servers, whatever) which queries the second tier as to which
might  be  the best nodes available to the request, to which the third
tier  then  calculates the possible circuits, and gives one to the tor
user at random.

What  happens if tier one is compromised? Everyone gets busted, unless
the Tor program itself has a way to authenticate if the first tier has
authority  and  a  true  identity.  And  naturally  there  is internal
verification of Tier 1, 2, and 3.
