The name comes from the card game poker which is one of the games to which this kind of problem applies. A commutative scheme means that if some data is encrypted more than once, the nad in which you decrypt this data will not matter. Example: Alice has picked cards 1 to 5 in the shuffled deck.
Furthermore, because players ultimately decide which cards are dealt, non-trustworthy hoomomorphisms are unable to influence the game to the extent that is possible in traditional online poker. Please contact the server peivacy at. Finally, step one in the protocol may be done offline, allowing for large numbers of shuffled, encrypted "decks" to be pre-computed and cached, resulting in excellent in-game performance. To date, mental poker approaches based on the standard Alice-Bob protocol above don't offer high enough performance for real-time online play. A copa casino ms paper by Golle [GOL05] describes a mental poker protocol that achieves significantly higher performance by exploiting the properties of the poker game to move away from the encrypt-shuffle model.
