摘要
提出了一套基于混沌加密算法的网络软件包分级保护的完整解决方案,根据软件包中不同模块的重要程度及其安全等级,在用户局域网内部建立软件包下载权限。在权限设定中,基于混沌系统的不确定性和初值敏感性,对不同安全等级的软件采用基于Logistic映射的混沌加密算法,形成唯一的注册码。因此,该保护机制在运行效率和加密安全性等方面达到了良好的效果。
An integrated classified Web software package protection scheme based on chaos encrypting alogrithm is proposed. It creates download rights in user LAN according to the significance grade and safe scale of the protected software package. According to the uncertainty and initial value sensitivity of chaotic systems, the exclusive registered code of the protected software package with different safe scale is created based on chaos encryption algorithm of Logistic maps. The proposed protection scheme yields an improvement in efficiency and security.
