在已知的安全求和方法基础上,针对合作各方可能不诚实提供数据或共谋的情况,提出了一种基于博弈论的安全多方求和算法。算法中各方基于最大化收益的目标,自觉选择诚实、不共谋的参与计算。分析表明算法能很好地完成计算,保护隐私信息。
On the basis of known secure sum computation, this paper concentrated on the issue of dishonesty and collusion when sharing data for secure sum computation and proposed a method based on game theory. In the method each participant consciously cooperative took a computation so that it could maximize its benefit or utility score during the entire secure sum computation process. The analysis demonstrates that the method is more efficiently and privacy information is preserved.
