摘要: 不同于现实世界和客户/服务器模式,在P2P游戏模式中缺少可信第三方,因此需要额外的机制来保证游戏的安全性。主要提出一种安全P2P扑克牌游戏的协议,该协议基于常规置换操作和对称加密算法。逻辑安全分析证明该方法是安全的,可以保证游戏的公平性。另一方面该方法的信息交互量少,消耗的通讯开销相对较小,因此适合于对能耗敏感的手持无线设备。

Abstract: Unlike real world and C/S model,it is difficult for P2P games to guarantee security and fairness because it lacks of a Trusted Third-party(TTP).In this paper,a secure scheme for P2P poker games is proposed,which is based on common operations,such as permutation and symmetric cryptography.The logic security analysis manifests that it is secure and fair.On the other hand,the communication costs of the scheme is low so that it can be used to wireless hand-hold devices.
