Lower Bounds for Non-Black-Box 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...

Lower Bounds for Non-interactive Zero-Knowledge
Abstract. We establish new lower bounds and impossibility results for noninteractive zero-knowledge proofs and arguments with set-up assumptions. – For the common random string m...

A Note on the Round-Complexity of Concurrent Zero-Knowledge
Abstract. We present a lower bound on the number of rounds required by Concurrent Zero-Knowledge proofs for languages in NP. It is shown that in the context of Concurrent Zero-Know...

Private Coins versus Public Coins in Zero-Knowledge Proof Systems
Goldreich-Krawczyk (Siam J of Comp’96) showed that only languages in BPP have constant-round public-coin black-box zero-knowledge protocols. We extend their lower bound to “ful...
