Encrypting the File System on a Single-Board Computers Platform and Using Linux Unified Key Setup with Physical Access Keys

Abstract

The object of the research is the security of the file system of a single-board platform. As part of the research reported in this paper, a method has been proposed to protect the file system using encryption. Implementing a Linux Unified Key Setup paired with a password or Universal Serial Bus key has been demonstrated. The advantages of Linux Unified Key Setup for this task and the possibilities for system configuration and encryption method depending on the use case and hardware configuration has been outlined. As a result, the administrator of a single-board computer can store and work with sensitive information in a more secure environment. This will allow the user to be sure that their private information will not be accessible in case of theft or attempted hacking of the device.
