Research on Zero-Knowledge Proof Protocol

Zero-knowledge proof protocol is a critical component of cryptography, which in recent years has raised increasing concern of many scholars.Its application field is very extensive,and it has made breakthrough progress in many aspects,including mathematics and network safety and so on. This article launches the elaboration from the concept, nature, mathematics theory, general proof process of the zeroknowledge proof , focusing on the application research of polynomial function root, graph isomorphism, cloud storage service, RFID, proxy digital signature and identity authentication etc.Finally, the direction for further research is summed up.The systematic introduction to zero-knowledge proof protocol has important theoretical guidance and practical significance on attracting more scholars involved in the research as well as expanding application fields.
