基于椭圆曲线密码体制的一种软件注册方案及实现

软件是智力劳动的成果，大部分的软件开发者都采取了使用注册码的方式对其进行保护。基于椭圆曲线密码体制，提出了一种新的软件注册方案并予以实现。该方案不仅可以使得一个软件对应一台计算机只有一个唯一的注册码，而且其建立在椭圆曲线离散对数难题之上，相对于传统软件注册方法具有更高的密码强度。可以有效地实现对软件版权的保护。

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 .
