Open publisher page 0 citations

Abstract

Zero knowledge proof of secret is a basic method in cryptography which is used in digital signature. For a zero-knowledge proof scheme of possessing a DSA digital signature which was given and proved by scholars,this paper analyzed the security again,and proposed an improved zero-knowledge proof of possessing a DSA digital signature. The scheme can prevent the third party who does not have the signature cheating and attacking,at the same time it can prevent the confirmed cheating.
