A quick tor analysis that I did in my spare time.

Over the last few months I have been having a play with a crude tor  
simulator (it just simulates the circuit building part of tor).  I did  
three different types of simulation from point of view of a number of  
organisations trying adding their own nodes to the network in an  
attempt to control both the entrance and exit nodes.

A quick summary of the results was that it would be quite easy for one  
organisation to control both the entrance and exit nodes in the tor  
network by simply putting enough resources in (i.e. a lot of good  
quality nodes that are both entrance and exit nodes).  If more than  
one organisation tries to do this though then the overall quantity of  
circuits controlled by any organisation drops.

This wasn't a full time research project just something that I have  
done in my spare time to answer a question that I had.  I have more  
details about it in a blog post at  
"https://www.heckrothindustries.co.uk/2010/07/quick-tor-analysis/".
