the team was able to reverse engineer the protocol and come up with a system for brute forcing the key recovery process in a matter of hours.  they also created a proof-of-concept radio device that could be used to mimic a speedpass fob to purchase gasoline.

their cracking device utilizes 16 fpgas and is able to do in a couple hours what 10 general purpose pcs would do in 2 weeks, all for the price of about $3500.  this reminds me of the bombes used by british cryptanalysts to crack enigma cyphers in world war 2.  pretty cool stuff.
