On Secret Sharing Schemes
The concept of secret sharing has been introduced independently by Shamir and Blakley, as a tool to protect a secret from getting exposed or from being lost. It allows a so-called dealer to share a secret among the members of a set P , which are usually called players or participants, in such a way that only certain specified subsets of players are able to reconstruct the secret while smaller s...
متن کاملSecret Sharing Schemes Based on Room Squares
In this paper, we describe secret sharing schemes. We discuss Room squares and their critical sets. We propose a model of secret sharing based on critical sets of Room squares.
متن کاملSecret sharing schemes on graphs
Given a graph G, a perfect secret sharing scheme based on G is a method to distribute a secret data among the vertices of G, the participants, so that a subset of participants can recover the secret if they contain an edge of G, otherwise they can obtain no information regarding the key. The average information rate is the ratio of the size of the secret and the average size of the share a part...
متن کاملOn Proactive Secret Sharing Schemes
This paper investigates the security of Proactive Secret Sharing Schemes. We start with revision of the mobile adversary model of Herzberg’s et al. imposing less restriction to the adversary. We first investigate the approach of using commitment to 0 in the renewal phase in order to renew the player’s shares. In the considered model some well known computationally secure protocols (which use th...
متن کاملAnonymous Secret Sharing Schemes
In this paper we study anonymous secret sharing schemes. Informally, in an anonymous secret sharing scheme the secret can be reconstructed without knowledge of which participants hold which shares. In such schemes the computation of the secret can be carried out by giving the shares to a black box that does not know the identities of the participants holding those shares. Phillips and Phillips ...
