基于一般访问结构的可验证多秘密共享方案

摘要

提出一个基于一般访问结构的可验证多秘密共享方案.方案中,秘密分发者可以动态地增加秘密的数量,各参与者的秘密份额可以重复使用.与现有的一些方案相比,该方案在防止分发者和参与者之间的各种欺骗时所需的模指数运算量更小,而且每共享一个秘密仅需公布3个公开值.因此该方案是一个安全高效多秘密共享方案.%This paper proposes a verifiable multi-secret sharing scheme which is based on general access structure. In this scheme, the dealers can increase the number of secrets dynamically, and the secret shadow of each participant can be reused. Compared with some existing schemes, the proposed scheme has less modular exponentiation operations in preventing a variety of deception between the distributors and the participants, and only 3 public values are required for sharing a secret. Therefore, this scheme is a secure and efficient multi-secret sharing scheme.
