On polynomial secret sharing schemes.

open access: yesIACR Cryptol. ePrint Arch., 2019
Nearly all secret sharing schemes studied so far are linear or multi-linear schemes. Although these schemes allow to implement any monotone access structure, the share complexity, SC, may be suboptimal - there are access structures for which the gap between the best known lower bounds and best known multi-linear schemes is exponential. There is growing

An Implementation of Image Secret Sharing Scheme Based on Matrix Operations

open access: yesMathematics, 2022
The image secret sharing scheme shares a secret image as multiple shadows. The secret image can be recovered from shadow images that meet a threshold number.

On the Optimization of Bipartite Secret Sharing Schemes [PDF]

open access: yesDesigns, Codes and Cryptography, 2010
Optimizing the ratio between the maximum length of the shares and the length of the secret value in secret sharing schemes for general access structures is an extremely difficult and long-standing open problem. In this paper, we study it for bipartite access structures, in which the set of participants is divided in two parts, and all participants

Multi-Secret Sharing Schemes [PDF]

open access: yes, 1994
A multi-secret sharing scheme is a protocol to share m arbitrarily related secrets s1,..., sm among a set of participants P. In this paper we put forward a general theory of multi-secret sharing schemes by using an information theoretical framework. We prove lower bounds on the size of information held by each participant for various access structures.

Decomposition construction for secret sharing schemes with graph access structures in polynomial time

open access: yes, 2010
The purpose of this paper is to describe a new decomposition construction for perfect secret sharing schemes with graph access structures. The previous decomposition construction proposed by Stinson is a recursive method that uses small secret sharing ...
