报告内容：A zero-knowledge proof system allows a prover to prove the validity of a statement to a verifier and reveal nothing else. Such proof system should protect honest prover in the sense that the prover should be able to convince the verifier if the statement is true. On the other hand, it should also be fair to the verifier. He should not be convinced by a false statement. A related notion is proof of knowledge, where the prover additionally shows that he possesses the witness of why the statement is true.  In this talk, I will first introduce the definition of zero-knowledge proof of knowledge (ZKPoK). Then I will recall the Stern’s protocol and how it was developed to handle versatile statements by using decomposition and extension technique, initially proposed by Ling et al.~[LNSW,PKC13].
