摘　　要：采用了CBC模式下的DES算法实现文件完整性检测,弥补了防火墙保护内部网络安全的不足,保证数据传输过程的真实性。当入侵者进入系统后,如果有一个块在传送时被人恶意改变了,该方法可以检测到系统可能受到了攻击,有效地解决了传输中数据安全性的问题。Uses the DES algorithm that works in CBC mode realize integrity of the document detection, make up the insufficiency of the firewall which protect network＇ s security, guarantee the authenticity of the data during transfer process. When the intruder entered the system, if a block is being changed maliciously in the transmission, this method can detect the attack, which may be effective in resolving the security of data in transmission.

关 键 词：CBC模式 DES算法 文件完整性 真实性 网络安全
