Securing IoT applications with Arm Cortex-M33 microcontrollers
Tonka, Marek ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
Bakalárska práca analyzuje vlastnosti moderných mikrokontrolérov s architektúrou ARM Cortex-M33 a ich prínos pre zabezpečenie IoT aplikácií. Teoretická časť je zameraná na predstavenie spoločnosti ARM spolu s charakteristikou architektúry ARMv8, na ktorej sú procesory Cortex-M33 postavené. Taktiež sa kladie dôraz na predstavanie novej technológie TrustZone, ktorá je klúčovým zabezpečovacím prvkom týchto procesorov. Následne je predstavený výber mikrokontrolérov a ich vlastností od piatich popredných polovodičových spoločností. Praktická časť zahŕňa inštaláciu a nastavenie dvoch IDE pre nasledovnú prácu s doskami NUCLEO-575-ZI-Q a LPC55S69-EVK. Na základe týchto vývojových dosiek sa testujú štyri jedinečné funkcie, ktoré poukazujú na výhody používania procesorov ARM na zabezpečenie aplikácií internetu vecí.

Support of Secure Boot in Systemd-Boot Project
Sekletár, Michal ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
The aim of this master thesis is to convey an ellaborate overview of Secure Boot, the technology used for an authentization during a platfrom boot up. Overview is followed by a description of contemporary implementations of Secure Boot found in the operating systems based on the Linux kernel. Finally, we propose a new implemenation of Secure Boot support in the systemd-boot project.

Tool for secure start and update of embedded device firmware
Böhmová, Monika ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
This bachelor thesis covers creation of a tool designed for secure boot and update of firmware of embedded microcontrollers. Cryptography algorithms and methods, which were used for security are thoroughly described. In the following sections, independent subparts of which the whole tool comprises are explained. The tool was succesfully created, tested and will be deployed in the following year.

Wireless Sensor Network
Nosko, Matúš ; Materna, Zdeněk (referee) ; Zemčík, Pavel (advisor)
The work was focused on creating a secure sensor network based on mesh topology, built on devices from Espressif. It also concentrates on code security and connecting this network to the cloud. The mesh network created is dynamic, regenerative, and self-organizing. The entire network is built on Wi-Fi, making it easy to connect to the internet, as the only condition for its operation is to have Wi-Fi at the installation site, eliminating the need for any special device to connect the network to the internet - it's gatewayless. Even if one node fails, the network self-organizes according to the newly created conditions and continues to function. The most modern security methods are used to secure the devices, such as secure boot and flash encryption. The MQTT protocol is used to connect the mesh network to the server. The MQTT broker, database, and API interface on the server side are dockerized. Thanks to these docker containers, it is easy to extend server parts. Also, values from devices are stored in a database and displayed on a website. The entire network solution was implemented in the ESP-IDF environment and tested on ESP32-S3 devices.
