We first explain the notion of secret sharing and also threshold schemes, which can be implemented with the Shamir’s secret sharing. Subsequently, we review social secret sharing [6,10] and its trust function. In a secret sharing scheme, a secret is shared among a group of players who can later recover the secret. We review the construction of a social secret sharing scheme and its application ...

A (t, n)-threshold secret sharing scheme is a method to distribute a secret among n participants in such a way that any t participants can recover the secret, but no t − 1 participants can. In this paper, we propose two secret sharing schemes using non-abelian groups. One scheme is the special case where all the participants must get together to recover the secret. The other one is a (t, n)-thr...
