一种混合加密方法在文件隐藏中的应用

A Hybrid Encryption Method in the Application of Files Hidden

文章从保护服务器中文件信息的角度,研究一种利用混合加密实现隐藏文件的方法,防止非法权限的用户窃取、拷贝和破坏文件.其过程首先用一款文件转换数字文本的软件将文件转换为数字文本,按照一定算法在数字文本中添加一串特征值,利用DES加密混合特征值的数字文本,实验结果只保存DES加密后的密文,删除源文件.实现隐藏服务器中重要文件,防止非法用户得到文件信息的目的.

From the perspective of file protection in the server, the paper instigated a kind of hybrid encryption method to achieve hidden files, and to prevent the illegal user from stealing the permissions, copy and destruction of documents forma- tion in the server. Firstly, the processed files will be converted to digital text using a digital text file conversion software via certain algorithm to add a bunch of eigenvalue on digital text. Then, the experimental results only saved DES encrypted ci- pher text, removing the source file using DES encryption of digital text mixed characteristic value. The experimental achieve- ment in hiding important file server can prevent illegal users from obtaining the purpose of document information.
