摘要：File System is an important component of a secure operating system. The need to build data protection systems is extremely important in open source operating systems, high mobility hardware systems, and miniaturization of storage devices that make systems available. It is clear that the value of the data is much larger than the value of the storage device. Computers access protection mechanism does not work if the thief retrieves the hard drive from the computer and reads data from it on another computer. Encrypted File System (EFS) is a secure level of operating system kernel. EFS uses cryptography to encrypt or decrypt files and folders when they are being saved or retrieved from a hard disk. EFS is often integrated transparently in operating system There are many encrypted filesystems commonly used in Linux operating systems. However, they have some limitations, which are the inability to hide the structure of the file system. This is a shortcoming targeted by the attacker, who will try to decrypt a file to find the key and then decrypt the entire file system. In this paper, we propose a new architecture of EFS called KVEFS which is based on cryptographic algorithms, FUSE library and key-value store. Our method makes EFS portable and flexible; Kernel size will not increase in Operating System.
