Atomic Update of an Embedded System
Čikel, Tomáš ; Koutenský, Michal (oponent) ; Grégr, Matěj (vedoucí práce)
This work focuses on the issue of atomic updates for embedded systems. Specifically, it focuses on the requirements which embedded systems place on their updates, strategies and technologies which are being used for updating these systems. Next the work introduces the Fire Truck Control System which is an embedded system for controlling fire trucks. Thesis analyzes the update process of this system and presents the design of a new update system which is based on RAUC. Update system implements the creation of updates and system in Yocto, uses Hawkbit for storing and deploying updates, modifies Rauc-Hawkbit-Updater to parse additional packages and implements ability to update devices on CAN bus. The results of this work allows to deploy atomic updates to Fire Truck Control System embedded system, and shows different technologies and solutions, which could be used to remove short comings of this implementation
Security Analysis of Home IoT Network
Čikel, Tomáš ; Jeřábek, Kamil (oponent) ; Pluskal, Jan (vedoucí práce)
This work focuses on the issue of the  security in home IoT network. Specifically, it focuses on the security issues of commercial IoT devices and their automation systems. In the work itself, it was firstly analyzed and identified specific threats specific for our network. To address these threats, the original automation systems and firmware on the devices were replaced by open-source implementations that were configured to address discovered threats. Although, there are still several security issues in a network with an open-source implementation, a large part of the security issues which were discovered has been eliminated.  The results of this work allows to configure a home IoT network using an opens-source automation system and firmware and proves that such a network is more secure than the network where the original factory-supplied automation systems and firmware on devices are used.
