Abstract
Abstract In this work we consider the Diffie-Hellman public-key model in which an additional short random string is shared by all users. This. which we call Public-Key Public-Randomness (PKPR) model, is very powerful, as we show that it supports simple non-interactive implementations of important cryptographic primitives. We give a noninteractive implementation of Oblivious Transfer in the PKPR model. Our implementation is secure against receivers with unlimited computational power. Building on this result, we show that all languages in NP have Perfect Zero-Knowledge Arguments in the PKPR model.
