摘要： 随着便携式计算设备的普及，保存数据的存储设备失窃或遗失的可能性增大。在这种情况下，能够保证敏感数据不被泄露的唯一方案是使用数据加密技术。相对于其它加密方式，使用加密文件系统对用户透明、可靠，有着不容忽视的优势。文章在Linux 2.4操作系统上设计和实现了一个加密文件系统——Crypt-FS，并对其进行了介绍。

Abstract: Portable computers become more and more popular. The storage device which stores sensitive data has the more chances to be lost or stolen. In this situation, the only way which can protect the sensitive data is using data encryption. Cryptographic file system is the best candidate in this scopes. Its lucider and reliable for the user. And it has more advantage which isn't to be ignored than other encrypt ways. This paper describes the design and implementation of the cryptographic file system Crypt-FS on Linux 2.4.
