Autonomous control system for composite materials heating
Lapčák, Adam ; Levek, Vladimír (referee) ; Šteffan, Pavel (advisor)
This thesis focuses on designing an autonomous system intended for heating surfaces made of conductive composite material. The design involves smart electronics design for integration into distribution boards and the ability to control power switching elements. Emphasis is also placed on the possibility of remote system control via the internet network. For an easy deployment in any location, the autonomous system will use a mobile network. System control will be realized with a dedicated HTTP API server along with a custom user application.

Home security system
Čada, Jan ; Burda, Karel (referee) ; Lattenberg, Ivo (advisor)
This master thesis deals with the design and implementation of a security system for a family house. It consists of a central control panel, a control keyboard and detectors connected using cables. The first part of the thesis discusses the electronic security and fire alarm systems, describing the individual elements of these systems and their different types. Magnetic contacts, fire detectors, sirens and a mains power supply with UPS function are selected from the current offer based on a comparison of parameters. In the next section, a block diagram of the whole system is designed. Raspberry Pi Pico development board with an RP2040 microcontroller is selected along with a GSM module SIM800L for SMS alarm notification and an Ethernet module with a Wiznet W5500 chip for the possibility of implementing a web interface. Schematics of the individual modules of the system are designed - for the central control panel, input module with PCF8574 circuit and two PCBs of the control keyboard module, which is equipped with a button keyboard with backlight, character LCD display type 1602 and proximity sensor VL53L0X for automatic lighting when person comes closer than a defined distance. PCBs are designed according to the schematics. Their manufacturing is then ordered, all components are mounted and the PCBs are placed in a 3D printed enclosure in the case of the control keyboard, and on the mounting plate of the metal cabinet in the case of the central control panel, according to the designed mounting plan. For the selected piezo sirens, covers are designed and 3D printed in the design of the selected Paradox NV5 motion sensors. In addition to the central control panel and the control keyboard, door and window contacts, fire detectors and sirens are installed in the house. The next part is dealing with the development of the control software for the central control panel and control keyboard in MicroPython language and the design of a custom communication protocol on the RS-485 bus for communication between the central control panel and control keyboard. Both control programs are based on the state machine principle, and their state diagrams are presented in the thesis. Part of the text is also focused on the development of the central control panel web interface and integration of the desinged system into the Home Assistant open-source automation system. The last part describes the activation and testing of the system in real conditions of a family house.

Remote control of Solar inverter
Pohorský, Ondřej ; Kopečný, Lukáš (referee) ; Burian, František (advisor)
This thesis deals with the design and implementation of a remote monitoring device for the solar inverter SOFAR HYD-10-KTL-3PH. The assignment of this thesis was based on the knowledge and requirements of the author. The aim of this thesis is to create a device communicating with the inverter. The device will display the essential parameters on the website. From the website it should also be possible to control the outputs of the device, which can be used to switch appliances.

Simulation scenarios in NS2 demonstrating knowledge obtained in the MPKT course
Mašek, Jan ; Mlýnek, Petr (referee) ; Jeřábek, Jan (advisor)
The aim of the bachelor´s thesis is to develop simulation tasks for modeling of data networks. The tasks will be used in the course Modern communication technique (MKPT). The networks are simulated in the environment of Network Simulator 2 (NS2). A brief description of program environment NS2, as well as basics of Tcl language is mentioned in the introduction. Described is the possibility of simulation HTTP protocol in NS2 using OTcl PagePool classes. Totally six proposed tasks form the core of the thesis. The first task uses PagePool/Math and displays the simplest communication between client, server and cache. Next task uses PagePool/CompMath and it shows the communication between client, cache, Web server, FTP server and FTP client. The task, that uses PagePool/WebTraf class, simulates communication between two clients and three servers. The last three tasks are of different topologies and course of communication using PagePool/ProxyTrace. The exercises of this class are the most complicated and their input files allow defining whole communication. The outputs of exercises are given in graphs, log files of HTTP communication and the last task contains detailed instructions.

Tool for Analysis of JavaScript to Detect DOM XSS Vulnerabilities in Web Applications
Barnová, Diana ; Polčák, Libor (referee) ; Homoliak, Ivan (advisor)
The main goal of this thesis is to design a tool for analisys of JavaScript to detect DOM--based XSS vulnerability in web applications. Then to implement it and test it ethically. Cross--side Scripting (XSS) is one of the most common injection attacks on web applications that insert malicious code in an otherwise trusted site. An interpreted response by the browser is required for the detection and subsequent exploitation of DOM--based XSS vulnerabilities, therefore the tool captures the response from the Burp Suite proxy server. The analysis of this response uses two separate regular expressions aimed at searching for sources and sinks in the source code of the response. A set of payloads is used to determine if a site is exploitable. Subsequently, the user is warned of the possible danger. The output is a text file summarizing the results for the URL.

Identification of Useful Data for Lawful Interception
Holomek, Tomáš ; Veselý, Vladimír (referee) ; Polčák, Libor (advisor)
This thesis deals with the identification of useful data in lawful interception. First part summarizes the standards related to computer networks and lawful intercepts. Next part of the project focuses mainly on the HTTP application protocol, which is described in version 1.1. The work also specifies the classes into which the data traffic can be divided according to the importance to law enforcement agency. It introduces several methods of distribution of data streams into the proposed classes. Finally, the implementation of this methods has been tested for usability in network lines used today.
