摘要:

文章基于星型簇态构造了一种具有分级结构的簇态,利用所构造的簇态提出了一种动态、分级的量子秘密共享方案。秘密拥有者将具有分级结构的簇态粒子分别分发给每个代理人作为他的份额。被分配较高等级的粒子的代理人具有较高的权限而被分配较低等级的粒子的代理人具有较低的权限。每一等级的代理人都不能获得同等级、较高等级和较低等级的代理人的份额信息。由于簇态的可扩展性,所提出的分级的量子秘密共享方案是动态的,允许在同等级新增代理人、删除旧代理人以及不同等级之间代理人的升级和降级。最后,文章分析了所提出的协议的安全性。

Abstract:

A hierarchical cluster state was constructed on the basis of the starlike cluster state, and then a dynamic, hierarchical quantum confidentiality sharing protocol was proposed using the constructed cluster state. The secret possessor distributed cluster particles with a hierarchical structure to each agent as his share. Agents assigned to higher ranking particles had higher authority while agents assigned to lower ranking particles had lower authority. Each class of agent did not have access to share information for agents of the same class, higher classes and lower classes. Due to the scalability of the cluster states, the proposed hierarchical quantum secret sharing scheme was dynamic, allowing for the additon of new agents at the same level, removal of old agents, and the upgrading and downgrading of agents between different layers. Finally, the article analysed the security of the proposed protocol.

Key words: quantum secret sharing, hierarchical, starlike cluster state, dynamic
