Barak and Lindell showed that there exist constant-round zero-knowledge arguments of knowledge with strict polynomial-time extractors. This leaves the open problem of whether it is possible to obtain an analogous resu...

It is well known that all the known black-box zero-knowledge proofs of knowledge for NP are non- constant-round. Whether there exit constant-round black-box zero-knowledge proofs of knowledge for all NP languages unde...
