An interactive proof system (or argument) (P,V) is concurrent zero-knowledge if whenever the prover engages in polynomially many concurrent executions of (P,V), ...

Dec 18, 2014 · 0. = (enc0,f(π)). Since a valid proof is π, the cheating prover violates the one-wayness of f. Thus soundness holds. To obtain strong ...

Abstract. In [18] Goyal et al. introduced the bounded player model for secure computation. In the bounded player model, there are an a pri-.

Concurrent executions of a zero-knowledge protocol by a single prover (with one or more verifiers) may leak information and may not be zero-knowledge in toto.

Abstract. We present new and e cient concurrent zero-knowledge pro- tocols in the timing model. In contrast to earlier works which through.

Abstract. Loosely speaking, an interactive proof is said to be zero- knowledge if the view of every “efficient” verifier can be “efficiently” simulated.

Abstract—We present a constant-round concurrent zero-knowledge protocol for NP. Our protocol relies on the existence of families of collision-resistant hash.
