Rainbow Tables. (or the new ones but I can't remember their name).

Sorry if it's not as sexy as you thought, but I think this could make a pretty big impact in the security community.

That's an interesting idea. Although, ideally, I'll want a project that requires a supercomputer. Rainbow tables can be created through distributed computing.

(I also had the evil idea of seeing how many bitcoin I could generate on Titan, but I don't think the ORNL staff would even find that funny.)

Say this to the super computer administrators: "im doing pure compsci research; im attempting to find alternative implementations of one-way trapdoor functions to optimize proof of work validations" then spend the next time tuning your mining bot and pocket the 14.17 USD/BTC you generate. For research!

This is already being done (albeit not with the aforementioned computer) with the same tech that the Folding@Home people use.
