摘　　要：扑克协议是指在不需要第三方参与的情况下实现公平的扑克游戏。而常规的三方扑克协议在没有第四方的参与下若有两方联合起来则就可以实现不公平的扑克游戏,针对这一问题,提出一种改进的三方扑克协议,该协议通过第一次循环来实现所有的牌手使用自己的公钥对54张扑克进行加密,然后通过第二次循环来实现所有的牌手取得自己的牌并对上家牌手的牌进行逐次解密,再通过第三次循环来实现解密所有的牌。为验证该算法的性能,将改进协议与常规协议进行了对比实验,实验结果表明,改进协议有效地解决了公平性的问题。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.
