摘要
In this paper we provide a new cryptographic primitive that generalizes several existing zero-knowledge proofs and show that if a language L induces the primitive, then there exists a perfect zero-knowledge proof for L. In addition, we present several kinds of languages inducing the primitive, some of which are not known to have a perfect zero-knowledge proof.
