Zero knowledge sets (ZKS) [18] allow a party to commit to a secret set S and then to, non interactively, produce proofs for statements such as x ∈ S or x /∈ S. As recognized in...

Abstract. We introduce a notion of instance-dependent verifiable random functions (InstD-VRFs for short). Informally, an InstD-VRF is, in some sense, a verifiable random function [...
