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...

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...

A zero-knowledge proof (ZKP) is an interactive proof that allows a prover to prove the knowledge of a secret to a verifier without revealing it. ZKPs are powerful tools to deal wi...
