Abstract—In this paper we introduce two operations ofaccess structure to build large monotone span programsMSPs from small MSPs. Furthermore, we point out a newmethod of constructing secret sharing schemes realizing anyaccess structure, using MSPs.

Index Terms—secret sharing schemes, monotone span programs,access structure
