| 摘 要： | 文件作为计算机系统最重要的资源，加密是保护它的最重要的方法之一。目前的加密方法很多，但是大部分都是用户态的密码加密，操作繁琐且加密效果不理想。文中介绍了两种区别于前者的透明加密方法：钩子透明加密和过滤驱动透明加密，并对这两种方法进行了比较。对目前的热点技术——过滤驱动加密技术进行了比较深入详细的研究，该方法由于是在内核模式下运行，较之于用户态下的加密具有高效、安全、灵活等特点，本质上就是文件系统功能的扩展。

| Abstract: | File system is the most important resource in computer system,and encryption is a good method to protect them.At present,the majority encrypt methods are implemented on user mode using keys,but unfortunately the effect is not very well.This paper will introduce two kinds of transparent encryption methods:API hook and file system filter driver,and meanwhile comparing this two methods,especially focus on the latter one-file system filter driver,for it is run on kernel mode,contrast with user mode encryption,i... |
