【 摘 要 】

This paper describes a file system that enables transparent encryption and decryption of files by using advanced, standard cryptographic algorithm, Data Encryption Standard (DES) [1]. Any individual, including super user, or program, that doesn't possess the appropriate passphrase for the directory which contains encrypted files cannot read the encrypted data. Encrypted files can be protected even from those who gain physical possession of the computer on which files reside [2]. ‘CifrarFS’, an encrypted file system using ‘File system in USEr space (FUSE)’ maintains all the files in a specific directory in an encrypted form and decrypts them on demand. It encodes the file name while storing but decodes it while viewed from the mount point. We propose an idea of watermark in every encrypted file that is validated before decryption and also log all the operations on ‘CifrarFS’. It is a stackable file system that operates on top of ext3. It does not need root privileges.
