Improve this question

I have to do a graduation project:

• Theme: Crypt开发者_运维问答ography
• Development time: 2 months max

I am looking for creative ideas :), not simple proof of concepts ;)

Thanks

You could create an actual implementation of a fair Mental Poker game. There's plenty of open source card games out there that you could use for the user interface part, leaving the crypto and network protocol as the main work you'd have to do.

The original SRA implementation is neither fair (quadratic residuosity leaks) nor completely private (strategy must be revealed after showdowns).

At Certimix (http://www.certimix.com) we've developed the first real-time complete mental poker protocol, but we haven't published the paper yet.

You can implement other protocols such as:

BS03 is the best, but still is too slow for more than a couple of players.
