Jun Xu, Jiwen Zeng, and Xiaomin Zha

Abstract

Any access structure is the multipartite access structure, The set of players is devided into K different entities, in such a way that all players of the same role in the multipartite access structure, we suppose there is a threshold access structure in every different entity, there is also a threshold access structure in K different entities, we consider their composite access structure, then a new family of Multipartite Access Structure will be given, we will provide secret shring scheme realizing it and prove it is ideal.
