A Note on Zero-Knowledge Proofs of Knowledge and the ZKPOK Ideal Functionality
Carmit Hazay and Yehuda Lindell
Abstract: In this note, we provide a formal proof of the fact that any protocol that is a zero-knowledge proof of knowledge for a relation $R$ is also a secure protocol for the zero-knowledge proof of knowledge functionality, where the latter is defined according to the standard framework of stand-alone secure computation. Although this is a well-known fact, to the best of our knowledge, no full proof of this has been published.
