ECC算法在软件保护中的应用及安全性分析

椭圆曲线密码体制基于其长度小、安全性高等特点在公钥密码系统中得到广泛应用，其安全性是基于椭圆曲线上的离散对数的难解性，它还依赖于椭圆曲线的选择。建立椭圆曲线密码体制的首要问题之一就是产生能够抵抗已有算法攻击的安全的椭圆曲线。文中主要将ECC加密技术应用于注册码软件加密保护方案中，对其进行了抗密码分析能力的讨论，最后对ECC算法的安全性进行研究及分析。因此，基于其极强的安全性ECC加密技术将会广泛地被应用。

Application and Security Analysis of ECC Algorithm in Software Protection

Elliptic curve cryptosystem based on its shorter length,high security features in the public key cipher system is widely used, its security is based on the elliptic curve discrete logarithm abstruse, it also depends on the selection of elliptic curve. Establishment of elliptic curve cryptography is one of the most important problems is to produce secure elliptic curve can resist the attack of existing algorithms. The ECC encryption technology is applied to the register code software encryption and protection scheme, the cryptanalysis-resisting ca- pacity is discussed, finally the ECC algorithm security is researched and analysed. Therefore, based on its strong security ECC encryption technology will be widely applied.
