This article deals with a Linux-based cryptographic protocol file system known as sshfs. SSHFS stands for Secure Shell File System and is based on another well-known protocol called FUSE. So what is FUSE? FUSE is a userspace filesystem framework. It consists of a kernel module (fuse.ko), a userspace library (libfuse.*) and a mount utility (fusermount). FUSE allows the use of sshfs, which is a secure network file system using the sftp (Secure File Transfer) Protocol.
