A real world application of secure multi-party computations (transcript of discussion)

Abstract

We start with a deck of cards, which is sorted in order, in suits. Two dealers each get given a key, and these numbers here represent a series of piles, and the order into which they deal the cards into the piles. The sequence is randomly generated by the computer in advance. For the second dealer, there's another permutation that looks the same. This is also random, although it is actually a mapping between the intermediate state and the desired hand we need at the end. But since those are both randomly generated, it's also random. Each dealer only sees one of the keys. © 2011 Springer-Verlag.
