Prototype of Intrusion Solution for Mobile Networks
Kamenský, Timotej ; Letavay, Viliam (referee) ; Veselý, Vladimír (advisor)
Spolu s rozvojom mobilných sietí stúpa aj dôležitosť ich zabezpečenia. Zraniteľnosti jed- notlivých mobilných protokolov na vrstve L1 - L3 je možné ľahko zneužiť. S použitím malého a relatívne lacného Software Defined Radio je možné implementovať rôzne druhy útokov cieliacich na mobilné siete. Cieľom tejto práce je vytvoriť intruzívny nástroj, implementujúci dostupné útoky. Tie zahrňujú zarušenie spojenia, Zníženie kvality služieb, Denial of Service, Sledovanie polohy, IMSI catcher.

Receiving and decoding of meteorological signals
Tuchyňa, Juraj ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
The main purpouse of this project is theoretical analyze of data receiving from NOAA (National Oceanic and Atmospheric Administration) meteo-satallites. The project is focused on data processing and decoding them. Received data will be processed and represented. We will use software defined radio (SDR) to help us to understand basic principles of signal processing. We will design conception of receiver in block diagram. Building of functional receiver will be the major part of bachelor thesis.

SDR-based UHF RFID communication analyzer
Vychodil, Josef ; Zamazal, Michal (referee) ; Povalač, Aleš (advisor)
Main topic of this thesis is development of software for capture and analysis of RFID communication in UHF band (standard EPC Class-1 Generation-2). One part of the work is focused on the basics of the RFID systems, software defined radio concept and graphical programming language LabVIEW. Main part of this thesis is discussing the developed software itself, its methods and principles. Next part is dedicated to present the graphical user interface of created application and its functionality. Last part of this thesis contains examples of captured and analysed processes in UHF RFID communication.

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.

SDR Signal Processing for Portable Monitoring Station
Svobodník, Petr ; Záplata, Filip (referee) ; Šebesta, Jiří (advisor)
Goal of this thesis is to develop portable monitoring station for radio spectrum monitoring and its controlling application for use by Czech Telecommunication Office. The station is based on Software Defined Radio (SDR) and capable of monitoring in the range of 1 MHz - 6 GHz. Developed application controls not only the SDR but also the external RF unit (including choice of receiving antenna, filter, optional amplification/attenuation and azimuth of antenna rotator). Measurement processed by computer and displayed graphically in form of spectrum diagram and waterfall diagram. Furthermore, the application will perform spectral measurement in compliance with requirements of International Telecommunication Union. The application is also capable of recording into the file and of analyzing historical data from the previous measurement.

Signal analyzer based on universal USB DVB-T receiver
Hoferek, Jakub ; Maršálek, Roman (referee) ; Derbek, Vojtěch (advisor)
This thesis deals with using a commercially available USB DVB-T tuner for spectrum analysis. In the first part, there are other possible platforms compared to income described hardware specific receiver tuner R820T and AD converter RTL2832. The next part is realized by a spectrum analyzer and a simple FM receiver. These functional units are created on GNU Radio and Matlab.

DAB Radio Receiver
Pišťák, Ondřej ; Götthans, Tomáš (referee) ; Dřínovský, Jiří (advisor)
This work is focused on design and construction of software defined radio that can play DAB+ standard. The received signal is processed by USB receiver RTL-SDR BLOF with 8 bits resolution A/D convertor RTL2832U and small single-board computer Raspberry Pi 3 (Model B). The work deals also with design and realization of control panel by which the radio is controlled. The LCD display is connected to Raspberry Pi and used for the screen information about currently playing radio program.

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.
