Resettable Zero-Knowledge in the Weak Public-Key Model
A new public-key model for resettable zero-knowledge (rZK) protocols, which is an extension and generalization of the upper-bounded public-key (UPK) model introduced by Micali and ...

Zero-Knowledge
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...

Concurrent Zero Knowledge with Logarithmic Round-Complexity
We show that every language in NP has a (black-box) concurrent zero-knowledge proof system using ˜O(log n) rounds of interaction. The number of rounds in our protocol is optimal,...

Zero-Knowledge Proofs with Witness Elimination
Abstract. Zero-knowledge proofs with witness elimination are protocols that enable a prover to demonstrate knowledge of a witness to the verifier that accepts the interaction prov...
