— In this paper we introduce two operations of access structure to build large monotone span programs MSPs from small MSPs. Furthermore, we point out a new method of constructing...
The visual secret sharing (VSS for short) scheme is a secret image sharing scheme. A secret image is visually revealed from overlapping shadow images without additional computation...
Error-correcting codes and matroids have been widely used in the study of ordinary secret sharing schemes. In this paper, the connections between codes, matroids, and a special cla...
