摘要:

基于中国剩余定理,提出了一个特殊权限下的参与者有权重的动态多重秘密广义门限共享方案,该方案通过一次秘密共享就可以实现对任意多个秘密的共享.方案中每个参与者的子秘密可以多次使用,共享秘密更新时,无需更新参与者的子秘密,同时,可以灵活地增加或者删除某个参与者.

关键词: 特殊权限, 门限秘密共享, 多重秘密, 权重不同, 动态

Abstract:

A dynamic generalized threshold multi-secret sharing scheme among weighted participants of special access right based on Chinese Remainder Theorem is introduced, it permits that multiple secrets be shared in one secret sharing session. The sub-secret of every participant can be used many times,and the secrets can be renewed without renewing the sub-secrets of the participants, furthermore, a participant can be freely put into or removed.

Key words: special access right, threshold secret sharing, multi-secret, weighted, dynamic
