混合加密算法在软件防盗版中的应用

Application of Hybrid Encryption Algorithm in Software Anti-Piracy

提出了加密时把RSA公钥密码算法和MH背包公钥密码算法相混合,从而提高破解难度。把这种混合加密方法用于软件防盗版中,采用一台计算机,一个不同的注册码方式保护软件防止盗版,有效地阻止未被授权用户运行和使用软件,从而促进共享软件及其他软件的销售。

In this paper,RSA and MH knapsack public key cryptography algorithms are mixed together to increase the difficulty of decryption.And this hybrid encryption algorithm is applied in software anti-piracy,the registration code of one computer is different from the other computer in order to protect software Anti-piracy,effectively prevent unauthorized users,promote the sales of shareware and the other software.
