Fair-Zero Knowledge
Abstract. We introduce Fair Zero-Knowledge, a multi-verifier ZK system where every proof is guaranteed to be “zero-knowledge for all verifiers.” That is, if an honest verifi...

Concise Vector Commitments and their Applications to Zero-Knowledge Elementary Databases
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...

Zero Knowledge and Soundness Are Symmetric
We give a complexity-theoretic characterization of the class of problems in NP having zero-knowledge argument systems. This characterization is symmetric in its treatment of the ze...
