Abstract

Abstract-By analyzing the basic principles of file encrypting system, the essay mainly research and implement the transparent encrypting file system which is based on the filter driver in the kernel driver layer. With the help of this system, not only a certain type of file can be encrypted, but the specified file or folder can also be encrypted easily and efficiently. The system applies shared memory, windows massage mechanism, I/O driver technology and the other technology to implement information synchronization and data communication between the user model and kernel made. Compared with other encrypting technologies, the file system filter driver which is based on the transparent file encrypting technology has overcome the shortcomings of several other technologies. Because it is much more closer to the kernel, it can effectively intercept any file operation. The experiment results show that the interception efficiency is higher than other file encrypting system. Besides , the system's performance is much more security and reliable.

基于Windows内核的透明加密文件系统研究与应用

本文在分析文件加密系统基本原理的基础上，重点研究并实现了基于内核驱动层过滤驱动的透明加密文件系统。在该系统的帮助下，不仅可以对某一类型的文件进行加密，而且可以对指定的文件或文件夹进行加密。该系统采用共享内存、窗口按摩机制、I/O驱动技术等技术实现了用户模型与内核之间的信息同步和数据通信。与其他加密技术相比，基于透明文件加密技术的文件系统过滤驱动程序克服了其他几种加密技术的不足。因为它更接近内核，所以它可以有效地拦截任何文件操作。实验结果表明，该系统的拦截效率高于其他文件加密系统。此外，该系统的性能更加安全可靠。
