| 本文提出了一种基于树的秘密共享方案，该方案基于树的禁止结构.树中的一个节点代表一个秘密共享的参与者，树中没有父子关系的两个节点是授权子集，即树中没有父子关系的成员可以恢复主秘密，而其他成员组合不能得到主秘密的任何信息.分析表明该方案具有存储负载小、安全性高的特点. |
| 英文摘要: |
| This paper proposes a tree-based scheme for secret sharing,which is based on the mixed structure.In the scheme,a vertex denotes a participant,and the subset includes the parent vertex and the child vertex in not less than three vertexes which are both authorized subsets,namely the subsets including two filiations participants and the subsets including not less than three participants which can both recover the master key,while other subsets cannot recover the master key and obtain no information.The analysis shows that the scheme has the properties of less storage and high safety. |
