Anomaly Detection in IoT Networks
Halaj, Jozef ; Hujňák, Ondřej (referee) ; Kořenek, Jan (advisor)
The goal of the thesis was an analysis of IoT communication protocols, their vulnerabilities and the creation of a suitable anomaly detector. It must be possible to run the detector on routers with the OpenWRT system. To create the final solution, it was necessary to analyze the communication protocols BLE and Z-Wave with a focus on their security and vulnerabilities. Furthermore, it was necessary to analyze the possibilities of anomaly detection, design and implement the detection system. The result is a modular detection system based on the NEMEA framework. The detection system is able to detect re-pairing of BLE devices representing a potential pairing attack. The system allows interception of Z-Wave communication using SDR, detection of Z-Wave network scanning and several attacks on network routing. The system extends the existing detector over IoT statistical data with more detailed statistics with a broader view of the network. The original solution had only Z-Wave statistics with a limited view of the network obtained from the Z-Wave controller. The modular solution of the system provides deployment flexibility and easy system scalability. The functionality of the solution was verified by experiments and a set of automated tests. The system was also successfully tested on a router with OpenWRT and in the real world enviroment. The results of the thesis were used within the SIoT project.

Wireless sensor based on LoRa technology
Pospíšil, Jan ; Krajsa, Ondřej (referee) ; Troják, David (advisor)
The bachelor thesis in theoretical part is focused on wireless technologies used for home control and automation devices where low power consumption is required. There are mentioned possibilities of each technology, energy requirements, range and throughput. The result of practical part is design and construction of a wireless temperature sensor which uses LoRa technology to communicate with a gateway and is also capable to last on battery for years. Additional feature is user possibility to use GPIO pins in form of relays. The task also covers design and construction of a gateway which listens for LoRa packets and communicates with PHP application on server side. Last step of practical part is focused on design of PHP application, which is responsible for visualization of received data.

A Framework for generating Traffic in IoT Networks
Švehla, Ľubomír ; Staněk, Miroslav (referee) ; Polák, Ladislav (advisor)
The point of this master's thesis is to design a framework capable of receiving and processing and also generating and sending packets of BLE, Z-Wave and IQRF technologies. In addition to designing the software itself, it also deals with choosing suitable hardware. Selected hardware is SDR device HackRF~One. The software solution is implemented in C ++ and counts on the use of third-party tools.

Secure Gateway for Wireless IoT Protocols
Hošala, Martin ; Hujňák, Ondřej (referee) ; Kořenek, Jan (advisor)
Táto práca bola zameraná na vytvorenie funkčného prototypu zabezpečenej brány pre bezdrôtové IoT protokoly s využítím BeeeOn IoT Gateway. Na vytvorenie výsledného riešenia bolo potrebné analyzovať existujúce zabezpečovacie systémy IoT, navrhnúť ich integráciu s BeeeOn Gateway a systém nasadiť. Ako zabezpečovacie systémy v tejto práci boli použité moduly NEMEA vyvinuté v rámci projektu SIoT. Výsledné riešenie beží na routeri Turris Omnia a pozostáva z BeeeOn Gateway, piatich detekčných modulov SIoT a ďalších modulov NEMEA potrebných pre plnú funkčnosť detektorov. Potenciálne hrozby sa zisťujú v sieťach Z-Wave, BLE a LoRaWAN. Používateľ môže so systémom interagovať prostredníctvom webového rozhrania systému Coliot, ktorý je tiež súčasťou výsledného riešenia a slúži na ukladanie a prezentáciu výsledkov detekcie. Funkčnosť systému bola overená experimentálne a množinou integračných testov. Testovanie odhalilo mnoho nedostatkov spojených s použitými podsystémami a väčšina z nich bola opravená. Výsledný systém sa používa sa v rámci projektu SIoT.

Home gate for IoT devices using Z-Wave technology
Resler, Tomáš ; Krajsa, Ondřej (referee) ; Hošek, Jiří (advisor)
This dissertation deals with the platform Z-Wave. This platform tries to create an universal system for smart home. The theoretical part of the work describes in details the platform itself as well as the applicable libraries for programming of applications and the available equipments. The practical part presents the new custom gateway. The hardware of this gateway is designed with utilization of the Z-Wave module, Raspberry Pi 3 microcomputer, touchscreen, powerbank and the body of the system. The body has been designed in the Solid Works CAD system and printed on a 3D printer. The needed firmware was loaded into the Z-Wave module ZM5304 and this module has been interconnected with the Raspberry Pi 3 through the printed circuit board of the custom design. The gateway drives OpenZWave network through the new own application written with help of Python wrapper of the library OpenZWave and other open source components. The part of the work is also the list and description of the alternative commercial gateways available on the Czech market.

Smart Home with the Third Party Sensors
Tisovčík, Peter ; Hujňák, Ondřej (referee) ; Viktorin, Jan (advisor)
The aim of this thesis was to acquaint with selected wireless sensors, which use Z-Wave and OASiS protocol and to create the uniform interface for BeeeOn system providing communication with the selected sensors. The theoretical part of the thesis describes sensors and USB devices that serve for communication with sensors or operating system to which they are connected. In the practical part, the BeeeOn application was extended by device manager which can support the other communication protocols.

Open-Source Implementation Of Smart Home Gateway For Z-Wave Protocol
Krejci, Jan
Z-Wave protocol is one of the most popular wireless protocols for home automation or smart home. However, in recent years there have been only few studies on practical measurements of this protocol. There are several manufacturers on the market, implying a vast array of devices, as well as deploying a commercial solution to the home is expensive and mostly focused on a single manufacturer’s portfolio. In this article, we designed and implemented our own Z-Wave home gateway for a smart home system based on open source software. We verified the feasibility of the proposed gate using the prototype and evaluated its performance according to the execution time of the command. We also discussed the limitations of the Z-Wave protocol based on our experience.
