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. Nettet2.1 Linear Secret Sharing In this section we de ne the notion of linear secret sharing that we will use throughout this paper. Most of the presentation here can be seen as a simpli ed version of [CDN15, Section 6.3], but it can also be regarded as a generalization since we consider arbitrary vector spaces. Similar notions have been considered

We note that 2-out-of-2 additive secret sharing can easily be extended to any n-out-of-nadditive secret sharing.

Secret sharing (also called secret splitting) refers to methods for distributing a secret among a group, in such a way that no individual holds any intelligible information about the secret, but when a sufficient number of individuals combine their 'shares', the secret may be reconstructed. Whereas insecure secret sharing allows an attacker to gain more information with each share, secure secret sharing is 'all or nothing' (where 'all' means the necessary number of shares).
