Secret Sharing Schemes With General Access Structure Based On MSPs
— 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...

On Codes, Matroids, and Secure Multiparty Computation From Linear Secret-Sharing Schemes
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...

Almost Optimum Secret Sharing Schemes Secure Against Cheating for Arbitrary Secret Distribution
We consider the problem of cheating in secret sharing schemes, cheating in which individuals submit forged shares in the secret reconstruction phase in an effort to make another pa...

Error-Set Codes and Related Objects
By considering a new metric, Nikov and Nikova defined the class of error-set correcting codes. These codes differ from the errorcorrecting codes in the sense that the minimum dis...

Monotone Circuits for Weighted Threshold Functions
Weighted threshold functions with positive weights are a natural generalization of unweighted threshold functions. These functions are clearly monotone. However, the naive way of ...

An approach for fault tolerant and secure data storage in collaborative work environments
We describe a novel approach for building a secure and fault tolerant data storage service in collaborative work environments, which uses perfect secret sharing schemes to store d...
