[Hardware] GPU-based RC5 cracking

[gmeurice at dice.ucl.ac.be]

Hello,

I was wondering the same thing: could GPU be used efficiently to break
RC5?
However that may be, I think it is just another mean (in addition to
software and fpga). Of course, the advantage is that a lot of people
have already a powerful (crypto)graphical card. The current
disadvantage is that we will need people to do the job.
I'm completely unable to foreseen what could be the performances of
such a solution.

I'm ready to discuss with people about that, but I'm a newbie in this
area and will not have the time to do the job.

About GPU: if I understand well, pixel shaders are the area of interest.

By the way, a RC4 breaker was already build using GPUs (but using it
for RC5 is probably really different).
