Reusable multi-attributes hierarchical threshold scheme
摘要
Abstract
A hierarchical threshold scheme is used to solve the secret sharing with a hierarchical access structure where participants are partitioned into different levels. In a hierarchical access structure, the participants group is divided into dif-ferent levels based on the privilege, and a certain number of participants from each level are required to recover the secret. In the past hierarchical threshold schemes, participants are partitioned based on a single attribute. But in practice, each par-ticipant always has several attributes, and the group of participants always should be partitioned based on different attri-butes to satisfy the security requirements. Even though hierarchical threshold schemes have been studied extensively in the past years, few of the existing solutions can solve the above problem. A reusable multi-attributes hierarchical threshold scheme based on Tassa’s scheme which uses Birkhoff interpolation, and Mignotte’s scheme which uses Chinese Remainder Theorem, is proposed to solve this problem in this paper.关键词
