We revisit the composability of different forms of zero-knowledge proofs when the honest prover strategy is restricted to be polynomial time (given an appropriate auxiliary input)...
This paper presents the first type system for statically analyzing security protocols that are based on zero-knowledge proofs. We show how several properties offered by zero-knowl...
A shuffle is a permutation and re-encryption of a set of ciphertexts. Shuffles are for instance used in mix-nets for anonymous broadcast and voting. One way to make a shuffle verif...
Quadratic residuosity and graph isomorphism are classic problems and the canonical examples of zero-knowledge languages. However, despite much research e ort, all previous zerokno...
We examine the concurrent composition of zero-knowledge proofs. By concurrent composition, we indicate a single prover that is involved in multiple, simultaneous zero-knowledge pro...
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...
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...
Applications such as e-commerce payment protocols, electronic contract signing, and certified e-mail delivery require that fair exchange be assured. A fair-exchange protocol allo...

Abstract. We investigate whether it is possible to obtain any meaningful type of zero-knowledge proofs using a one-message (i.e., noninteractive) proof system. We show that, under ...
