摘要
为了保护软件的版权,设计了一种基于动态密文的软件保护方法。该方法使用用户计算机的指纹信息和软件的附加信息作为用户计算机的特征信息,对这些特征信息用MD5算法生成MD5码,然后用DES进行加密生成密文。在软件运行时,对存储的密文进行解密并读取其中的信息,然后读取当前计算机的指纹信息与密文中的信息进行比较,验证软件的版权,达到保护软件版权的目的。
A method about how to protect software is designed in this paper,which is based on dynamic ciphertext. In this method,the software uses the fingerprint information of user computer and additional information of software as the feature information of the user computer. The feature information was generated MD5 code using the MD5 algorithm,and then generated ciphertext by using DES. When the software runs,first it decrypts the ciphertext stored in the user computer and read the information from which,and then compares the fingerprint information read from user computer and the characteristic information read form the ciphertext to validate the software copyright and achieves the purpose of protection of software copyright.
