Impossibility and Feasibility Results for Zero Knowledge with Public Keys
In this paper, we continue the study the round complexity of black-box zero knowledge in the bare public-key (BPK, for short) model previously started by Micali and Reyzin in [11]....

A Dolev-Yao Model for Zero Knowledge
In cryptographic protocols, zero knowledge proofs are employed for a principal A to communicate some non-trivial information t to B while at the same time ensuring that B cannot de...

An Unconditional Study of Computational Zero Knowledge
We prove a number of general theorems about ZK, the class of problems possessing (computational) zero knowledge proofs. Our results are unconditional, in contrast to most previous...

Constant-Round Resettable Zero Knowledge with Concurrent Soundness in the Bare Public-Key Model
In the bare public-key model (BPK in short), each verifier is assumed to have deposited a public key in a file that is accessible by all users at all times. In this model, intro...

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...
