随着生活中盗版软件越来越多,对软件的加密保护越来越显得重要。本文针对此问题,介绍了一种公钥密码体制---椭圆曲线密码(ECC),并利用该密码体制设计了一种软件注册机,可以有效的防止Cracker的跟踪和验证,在实际应用中具有一定的理论参考价值。 With more and more pirated softwares in life, it is more and more important to encrypt and protect the software. In this paper, a public key cryptosystem - ECC (Elliptic Curve Cryptography) is introduced in this paper, and a software registration machine is designed by using this cryptosystem, which can effectively prevent Cracker from tracking and verifying. In practical application Has a certain theoretical reference value.
