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,...

Min-round Resettable Zero-Knowledge in the Public-Key Model
In STOC 2000, Canetti, Goldreich, Goldwasser, and Micali put forward the strongest notion of zero-knowledge to date, resettable zero-knowledge (RZK) and implemented it in constant ...

Zero-Knowledge Watermark Detection and Proof of Ownership
The goal of zero-knowledge watermark detection is to allow a prover to soundly convince a verifier of the presence of a watermark in certain stego-data without revealing any infor...
