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...
In order to implement both the efficiency and security in the Peer-to-Peer (P2P) network, we design a trusted small world overlay P2P network with the role based and reputation bas...
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 investigate whether it is possible to obtain any meaningful type of zero-knowledge proofs using a one-message (i.e., noninteractive) proof system. We show that, under ...
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...
