distributed grid key attacks
I'm sure I read of a scheme (the original article was in German I recall) on the darker side of the Playstation3 where a team was assembling a voluntary distributed grid project to primarily crack all PS3 game codes, then to secondarily use the assembled horde of Cell power to go after assorted general crypto keys. A sort of closed user special interest group version of SETI or Folding.
What about when the kilocore (=1000 8 bits CPU's on a chip) class of supercomputer chips start getting built up into widespread devices - then it'll be up to quantum entaglement to keep data (temporarily) 'secret'. Moores Law is perceived as still valid for the next 25 years or so, so in the end I don't know how secret data will eventually be kept secret!
to 'worry' the Info Assurance experts further, do we know how many coherent qubits the D-Wave has achieved yet?
