Linux kernel operating system optimization for battery-powered devices
Lefler, Přemysl ; Komosný, Dan (referee) ; Benedikt, Jan (advisor)
his thesis focuses on optimization of Linux-based operating system for a accumulator-powered device Raspberry Pi 4. Compared to other devices commonly used in Internet of Things projects, the Raspberry Pi 4 offers many functions within one device. However, the disadvantage is the high consumption of electricity. The aim of this thesis is to achieve greatest possible savings in electricity consumption of the Raspberry Pi 4 device, with regard to functionality of the device as a server for data collection from sensors.

Security of EDGE sensors
Jančík, David ; Lieskovan, Tomáš (referee) ; Ilgner, Petr (advisor)
This bachelor thesis deals with the security of EDGE sensors on the Raspberry Pi platform, which is used to store sensitive data on disk. In this thesis, the test device is Raspberry Pi 4. First, it examines and implements an SD card security module from Swissbit, Swissbit PS-45u, and Zymkey 4i from Zymbit. With the knowledge of Zymkey i4 and Swissbit to design and implement its own physical security module. Authentication is handled using smart cards that support the NFC communication. The components powered on the prototype board are an Arduino Nano, an accelerometer and a gyroscope, two connecting wires, two LEDs and an NFC interface.

Intrusion prevention system based on Raspberry Pi
Hirš, David ; Gerlich, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
The number of discovered vulnerabilities rapidly increases. For example in 2019 there were discovered 20 362 vulnerabilities. The probability of cyber-attacks realization is high. Therefore it is necessary to propose and implement automated and low-cost Intrusion Prevention or Intrusion Detection Systems (IPS/IDS). This implemetation can focus on home use or small corporate networks. The main goal of the system is to detect or mitigate cyber-attack impact as fast as possible. The master's thesis proposes IPS/IDS based on Raspberry Pi that can detect and prevent various cyber-attacks. Contents of this thesis are focus on description of cyber-attacks based on ISO/OSI model's Link and Network layers. Then there is description of IPS/IDS systems and theirs open source representatives. The practical part is focus on experimental workspace, hardware consumption of choosen detection systems, cyber-attacks scenarios and own implementation of detection program. Detection program is based on these chosen systems and puts them together to be easily manageable.

Intelligent Energy Measurements for Homeowners' Association Using 5G Networks
Horčička, Patrik ; Možný, Radek (referee) ; Mašek, Pavel (advisor)
Theoretical analysis of IoT communication technologies LPWAN. A more detailed analysis of 5G-IoT technologies in the licensed frequency band, such as NB-IoT and LTE CatM. Comparison of different energy meters (Smartmeters). List of supported application protocols for IoT devices (MQTT, CoAP, LwM2M, DLMS/COSEM) with more detailed information about DLMS/COSEM. Quectel UMTS & LTE EVB kit with BG770A-GL module was used to create the first reference 5G-IoT device. Measuring of radio properties in two locations. Creation of TLS tunnel for communication between server and RPI designed for DLMS/COSEM data.

Device for simultaneous acquisition of PCG and PPG signals
Matoušek, Denis ; Králík, Martin (referee) ; Mézl, Martin (advisor)
This bachelor's thesis deals with the design and implementation of equipment for phonocardiographic and photoplethysmographic measurements. The theoretical part discusses the description of the origin of heart sounds, the place and method of measurement in the framework of phonocardiography. The practical part describes several options for building individual devices with the help of a Raspberry Pi 4 or with the help of measuring technology and a non-soldering field. Subsequently, the best solutions for PPG and PCG data acquisition are selected. 10 volunteers were measured on the final device. The scanned data is processed in the Python environment. Individual measurement results are described, documented, compared, and evaluated against other measurements.
