由机器码动态生成矩阵实现的软件版权保护方案

A Scheme of Software Protection Based on Dynamic Constitution of Matrices from Machine ID

利用不可更改的机器码动态生成矩阵,设计了软件版权保护方法.因为用户提交的机器码与软件供应商返回的注册码之间并无明文和密文的关系,所以由机器码推算注册码的代数攻击不会成功,保证了算法的安全性.算例说明了算法的可行性.

This paper presents a scheme of software copyright protection based on dynamic constitution of matrices from unchangeable machine ID. Because the relationship between machine ID submitted by the user and the registration string retuined by the vendor is not of plaintext and ciphertext, existing algebraic attacks for a legal registration string from the machine ID will not success, assuring the security of the scheme. A numerical example illustrates the algorithm viable.
