In this paper, we continue the study the round complexity of black-box zero knowledge in the bare public-key (BPK, for short) model previously started by Micali and Reyzin in [11]....

We show that if any one-way function exists, then 3-round concurrent zero-knowledge arguments for all NP problems can be built in a model where a short auxiliary string with a pres...

Abstract. We show that only languages in BPP have public-coin, blackbox zero-knowledge protocols that are secure under an unbounded (polynomial) number of parallel repetitions. Thi...

In the bare public-key model, introduced by Canetti et al. [STOC 2000], it is only assumed that each verifier deposits during a setup phase a public key in a file accessible by a...

We construct the first general secure computation protocols that require no trusted infrastructure other than authenticated communication, and that satisfy a meaningful notion of s...
