基于分存策略的软件注册码加密保护

Software protection by register code and encryption based on divided-storage strategy

为解决验证易受攻击及加密强度不足的问题,对现有的软件保护方案进行研究,提出一种基于分存策略的注册码加密保护模型。将软件分为多个单元,采用多种加密方式对软件进行保护,通过分存策略对注册码和用户码进行分组,利用多个隐藏在程序中的密钥生成函数来计算各个加密单元的解密密钥。理论分析和实验结果表明,该模型成本低、开销小、算法安全性高,能有效增加软件保护的力度。

To solve the problem that the judgment is vulnerable to attack and the strength of the software encryption is insufficient,the existing scheme to protect software was researced,a dynamic register code model based on packet encryption was designed.The software was divided into several blocks and protected by various encryption methods.The register code and user ID were divided into many segments using the decomposition function,and each sub secret key was calculated through the key generation function hiding in the program.The low cost,small overhead and strong security were verified through theoretical analysis and experimental results.This model can effectively increase the strength of software protection.
