A Modified Three-party Poker Protocol
Fan Xiang-kui
Abstract
Poker protocol realizes the fairness of poker games without the third party's participation.However,the conventional three-party protocol without the presence of the fourth-party could cause unfair poker games if the two players collaborate with each other.In view of this situation,a modified three-party protocol is proposed.Based on the new protocol,all players use their own public keys to encrypt the 54 cards during the first cycling,then duding the second cycling,all players obtain their own cards and decrypt step by step the cards of the opponent on the left,then during the third cycling,all the cards could be decrypted in order to testify the reliability of the algorithm.The comparison experiment of the modified protocol and the conventional protocol shows that the modified protocol could effectively solve the problem of fairness.
