Abstract. We introduce and define the notion of identity-based zeroknowledge, concentrating on the non-interactive setting. In this setting, our notion allows any prover to widely...

Quadratic residuosity and graph isomorphism are classic problems and the canonical examples of zero-knowledge languages. However, despite much research e ort, all previous zerokno...

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...

We show new lower bounds and impossibility results for general (possibly non-black-box) zero-knowledge proofs and arguments. Our main results are that, under reasonable complexity...

In this paper, we initiate a study of zero knowledge proof systems in the presence of sidechannel attacks. Specifically, we consider a setting where a cheating verifier is allow...
