Discreet solitary games

Abstract

Cryptographic techniques have been used intensively in the past to show how to play multiparty games in an adversarial scenario. We now investigate the cryptographic power of a deck of cards in a solitary scenario. In particular, we show how a person can select a random permutation satisfying a certain criterion dixreetly (without knowing which one was picked) using a simple deck of cards. We also show how it is possible using cards to play games of partial information such-as POKER, BRIDGE and other carda games in solitary.
