摘要：针对传统秘密共享总是基于参与者的权力或地位分配权重的问题,考虑参与者的信誉值,把参与者的权重值与其信誉值联系起来,基于信誉值对参与者的权重进行重新分配,提出了基于信誉机制的权重分配函数,并以此为基础构建了一个基于信誉机制的加权秘密共享方案,分析表明重构算法中的重构邀请机制可以有效地促使参与者同意送行秘密重构,并且方案可以有效为每个参与者分配权重.
In order to solve the problem that the participants＇ weight was always distributed based on his power or status in traditional secret sharing, several weight distribution functions based on reputation mechanism was presented considering the participants＇ reputation value. The function relates the participants＇ weight value with reputation value effectively, and re- distributes the weight for the participant based on his reputation reasonably. And then a new weighted secret sharing scheme was constructed based on reputation mechanism. The analysis showed that the reconstructing invitation mechanism can effectively constrain the participants to reconstruct the secret, and the scheme can distribute weight for the participants reasonably.
