摘要: 多等级门限共享是目前最具现实意义的秘密共享方案之一,但目前已有的多等级方案计算量较大,且不具备防欺诈等安全特性。为提高多等级门限的使用效率和安全性,提出了一个计算复杂度较低的可预防欺诈的多等级秘密共享方案,并对方案性能进行了分析。

关键词: 门限秘密共享, 多等级, 欺诈检测

Abstract: Hierarchical threshold secret sharing is one of the most practical secret sharing schemes now.However,the current hierarchical scheme doesn’t provide the function of cheater-detection and it must deal with a large computing.In order to improve the security and practicability,this paper proposes a hierarchical threshold secret sharing with cheater-detection and lower computing complexity,and analyzes the properties.

Key words: threshold secret sharing, hierarchical, cheater-detection
