Composition of Zero-Knowledge Proofs with Efficient Provers
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)...

Type-checking zero-knowledge
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 Non-interactive Shuffle with Pairing Based Verifiability
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...

Perfect Zero-Knowledge in Constant Rounds
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...

On the Concurrent Composition of Zero-Knowledge Proofs
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...

Zero-Knowledge Proofs with Witness Elimination
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...

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...

Constructing fair-exchange protocols for E-commerce via distributed computation of RSA signatures
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...

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...

On the Possibility of One-Message Weak Zero-Knowledge
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 ...
