Playing games with imperfect information or randomness can be tricky when playing remotely without a trusted third party. “Mental Poker” is the term used for the cryptographic problems that arise. We will first see a traditional example of how to use commitment protocols to emulate a fair coin toss, and then move on to the trickier problem of card shuffling. While we will see that these problems are unsolvable in theory, bounding the computational power of the players can allow practical algorithms to be developed.
