A Software Registration Scheme and Its Implement Based on Elliptic Curve Cryptosystem

As a product of intelligence,software is protected by most software developers by adopting a mode of register code.Based on elliptic curve cryptosystem,this paper puts forward a software registration scheme which not only can achieve the effect that single software in a computer has just one register code,but also has more sophisticated cryptosystem than traditional software registration methods due to its security based on the difficulties of elliptic curve discrete logarithm problems.It is effective in protecting software copyright.
