| 摘 要： | 智力扑克是一种特定场景的安全多方计算,近些年来,学术界对智力扑克协议的研究基本都是基于可信第三方的.利用语义安全的加密体制,结合同时生效签名算法,巧妙地设计了一种不安全信道下无可信第三方的智力扑克协议.该协议能很好地确保游戏双方的公平性、能有效抵抗重放攻击,同时还具有不可否认性、不可伪造性和游戏过程可追踪性等优点.

| Abstract: | Mental poker is a secure multi-party computation solution in specific scene.In recent years,the studies on mental poker protocol in academe are mainly based on Trusted Third Party(TTP).Using the semantic secure encrypt algorithm,combining with the signature algorithm in which the two signatures become effective at the same time,a mental poker protocol without TTP in an unreliable channel was designed.The new protocol can ensure the fairness of game participators and resist the attack of playback,with the ad... |
