一种文件智能加密方法研究

A New File encryption Method

经典的文件加密算法(如AES等)有一个特点,即加密后的文件是乱码。这极容易被攻击者识别,进而实施暴力破解或干脆破坏文件。本文就这一问题,尝试根据文件的不同格式对文件进行智能加解密,在保证对文件重要数据进行加密的基础上,不破坏文件甚至是文件数据的原有格式,目标是使攻击者难以识别该文件是加密后文件,以达到更好的数据保护的目的。

Classical file encryption methods, such AES, makes the encrypted files are chaos. It is easy for attacker to recognize it and crack or destroy it. To deal with this problem, we propose a new file encryption method, which uses different format to encrypt different files. The new method doesn＇t only encrypt important data, but keeps files format. It makes attackers more difficult to recognize encrypted files and destroy important data.
