基于安全多方计算的可信防共谋协议模型

Trusted coalition-proof protocol model based on secure multi-part computing

n个互不信任的参与方共同计算一个函数,其中部分参与方形成联盟,通过共谋而破坏其他参与方的安全性,利用安全多方计算技术和通信通道,针对可嵌套共谋,提出可信防共谋协议模型。将模型运用到博弈论中,借助相关均衡的概念取代了可信第三方。

N parties were involved in the computation of a function,which did not trust each other.Some of them found a coalition and destroy the security of others through collusion.Based on secure multi-party computation and communica-tions channel,to the collusion that could be nested,a trusted coalition-proof protocol model was proposed.The concept of correlated equilibrium was used by the model in game theory for talking place the trusted third party.
