安全公平理性秘密共享方案

Safe and Fair Rational Secret Sharing Scheme

传统秘密共享方案因未考虑参与者的自利行为而导致方案的效率较低。为了提高秘密共享的通信效率和安全性,结合博弈论与双线性映射技术,设计公平的理性秘密共享方案。首先,在博弈论框架下引入理性参与者并设计理性秘密共享博弈模型;其次,利用双线性映射技术保证方案和理性参与者的可验证性和公平性;最后,通过对方案进行性能分析,表明了该方案不仅保证了安全性,并且有较高的秘密共享通信效率。

Traditional secret sharing schemes do not take into account the self-interested behavior of participants,which leads to low efficiency of the scheme.In order to improve the communication efficiency of secret sharing,game theory and bilinear mapping technology are combined to design a fair and rational secret sharing scheme.Firstly,introduce rational participants and design a ra⁃tional secret sharing game model under the framework of game theory.Secondly,this paper uses bilinear mapping technology to en⁃sure the verifiability and fairness of the solution and rational participants.Finally,the performance analysis of the scheme shows that the scheme not only guarantees safety,but also has higher communication efficiency.
