Abstract

We introduce the notion of non-uniformly sound certificates: succinct single-message (unidirectional) argument systems that satisfy a “best-possible security” against non-uniform polynomial-time attackers. In particular, no polynomial-time attacker with s bits of non-uniform advice can find significantly more than s accepting proofs for false statements. Our first result is a construction of non-uniformly sound certificates for all (Formula Presented) in the random oracle model, where the attacker’s advice can depend arbitrarily on the random oracle. We next show that the existence of non-uniformly sound certificates for (Formula Presented) (and collision resistant hash functions) yields a public-coin constant-round fully concurrent zero-knowledge argument for (Formula Presented).
