Application of elliptic curve cryptosystem in digital signature

Elliptic Curve Cryptosystem(ECC) belongs to public key cryptosystem algorithm which is a new technology.It is used for a basic digital signature.Elliptic curve digital signature is based on the difficulty of computing discrete logarithm.Compared with the other scheme,it is excellent and high in security with short key and rapid circulation.In this paper this paper implements a digital signature scheme based on elliptic curve cryptosystem by the VC platform.This scheme is based on the fact that there is no efficient method to tackle the problems of the elliptic curve discrete logarithm of elliptic curve over finite field.It is secure in theory and practical operation and convenient and easier in implementation as well.Finally,the paper discusses some problems such as making use of elliptic-curve to realize software registration and fight piracy.
