That is, fix any threshold secret sharing … NettetThe above scheme is sometimes referred to as \additive secret sharing". We note that 2-out-of-2 additive secret sharing can easily be extended to any n-out-of-nadditive secret sharing.

NettetIn Chapter 4, we de ne multiplicative linear secret sharing schemes and again characterise multiplicative linear secret sharing schemes in two ways. We explain the proof of the existence of (t+ 1)-out-of-n threshold linear secret sharing schemes over Z 232 with more than one share per miner. Chapter 5 is about threshold linear secret … NettetSecret sharing has as main motivation and application secure multi-party computation (MPC). Any linear secret-sharing scheme yields an MPC pro- tocol [14], and the family of all malicious coalitions of players the protocol can tolerate depends on the parameters of the LSSS listed above.

NettetIt is known [17] that if is a linear secret sharing scheme for , then there exists a linear secret sharing scheme for such that ˙( ) = ˙() . Consequently ( ) = () . The access structure on P is said to be based on a graph G if the participants are as vertices of G and the minimal qualified subsets are corresponding to the edges.
