摘　　要：为保护软件的版权,维护正版软件版权所有者的合法权益,需对软件进行加密。提出一种能够把软件绑定到特定计算机上的方法,实现过程运用Rijndael对称加密算法,根据计算机的硬件信息产生注册码作为对用户的授权,软件安装时将注册信息写入注册表。软件运行时通过检查注册表中相关信息来判断该计算机的所有者是否购买了注册码,以此达到保护软件版权的目的。将对称加密算法和注册表操作技术运用到软件加密中,能够在不依赖特殊硬件的情况下实现软件版权的保护。经过理论分析以及实验验证,证明该方法易于实现,保密程度较高。It is necessary to encrypt software in order to protect the copyright of software and protect the legal right of users who own original edition software.We proposed a kind of method that can binds software with specific computer.We implemented the whole process by utilizing Rijndael symmetric encryption algorithm to produce registration code,which could be used as authorization for users according to the hardware information of computer.We input registration information at the time of installation of software.We can achieve the purpose of protecting software copyright by checking related information in registration table therefore judge that if owner of computer bought registration code or not.We can implement the protection of software copyright without relying on special hardware by adding symmetric encryption algorithm and registration table operation technology into software encryption.Both analysis of theory and experiment validation demonstrated that this method is easy to be implemented and it possesses higher degree of confidentiality.
