Abstract. One of the main open problems in secret sharing is the characterization of the access structures of ideal secret sharing schemes. As a consequence of the results by Brick...
The search of efficient constructions of ideal secret sharing schemes for families of nonthreshold access structures that may have useful applications has attracted a lot of atten...
Error correcting codes and matroids have been widely used in the study of ordinary secret sharing schemes. In this paper, we study the connections between codes, matroids, and a s...
