利用过滤层驱动程序实现移动硬盘加密

The Realization of Mobile Disk's Encryption Through Filter Drivers Procedure

通过对磁盘驱动程序设备堆栈的研究 ,推演出利用过滤层驱动程序对移动硬盘进行扇区级别加密的实现方法 ,该方法具有速度快 ,算法可变 ,文件系统无关 ,加密彻底 ,抵御攻击手段齐全等优点 ,同时 ,该方法可以方便的移植到Linux等非Windows系统下。

Based on the research on device stack of disk driver, the author brings forward a method to encrypt contents of a mobile disk through filter drivers from the sector level. It is very fast, file system independent, the algorithm can be changed as wished, the encryption is thorough and there are many points which can prevent the disk contents from being cracked, and this can be ported to Non-Windows systems such as Linux.
