Automatické štítkování aplikací pro klasifikaci na úrovni síťových toků
Dubec, Branislav ; Žádník, Martin (referee) ; Poliakov, Daniel (advisor)
The thesis deals with the creation of a tool that can detect newly created network connections at the kernel level and in web browsers. It explains the theoretical foundations and methods of the network flow monitoring. It also describes how creating network connections works in the Linux and Microsoft Windows operating systems, with a special focus on sockets, and it offers options for monitoring network connections in web browsers, too. The creation of network connections is detected using BCC technology, where the system calls responsible for creating a new network connection are directly monitored. Monitoring of network traffic generated by web browsers is implemented through the browser extension webRequest. The main task of the tool is annotating this traffic by combining the information from the browser extension with the information about new network connections.

Network Traffic Encryptor on Linux Platform
Havlín, Jan ; Sysel, Petr (referee) ; Hajný, Jan (advisor)
This bachelor thesis focuses on providing encrypted communication between two Linux operating system stations. It involves encryption using the AES-GCM-256 cipher, which uses a hybrid key derived from three separately generated keys. The methods for generating these keys are Quantum Key Distribution, CRYSTALS-Kyber and Elliptic Curve Diffie-Hellmann. Thus, we use functions of three types of cryptography - classical, quantum and post-quantum. The paper also deals with the extension of the functionality of the original cryptography to authenticate the communicating parties using certificates and deployment of the encryptor in practice.

Programming of processors in 32- or 64-bit operation systems
Rášo, Ondřej ; Kyselý, František (referee) ; Balík, Miroslav (advisor)
Main topic of this thesis is Win32 application programming interface and symbolic instructions programming language. It can be divided into four parts. First part sums the basics of 32-bit programming in symbolic instructions language in Windows. Second part describes the Win32 resources for computer intercommunication. Third part presents, describes and comments selected problems in symbolic instructions language.Last part covers a creation of an example application. This application and its parts will be the content of computer exercises in VUT Brno FEEC subject Počítače a jejich periferie.

Network Interface for Keyword Spotting System
Skotnica, Martin ; Glembek, Ondřej (referee) ; Szőke, Igor (advisor)
A considerable part of the research in computer science is dedicated to speech recognition as the speech-controlled systems become useful in many applications. One of them is the keyword spotting which makes possible to find words in audio data. Such a detector is developed at BUT Faculty of Information Technology. The goal of this work is to propose a network interface to this keyword detector based on client/server architecture. Client connects to the server and sends audio data. Server runs keyword detector with this received data and sends the result of keyword spotting back to client. Finally client visualizes the result and interact with user.

Electrical installations in apartment building
Novotný, Jan ; Formánek, Marian (referee) ; Doležalová, Jana (advisor)
This bachelor's thesis deals with electrical wiring in apartment building. The aim is to describe the types of distribution networks, implementation possibilities of service lines, describe the individual parts of the wiring in the building and the principles of their implementation. Further describe basic electrical materials and to explain the design of artificial lighting. In the practical part the information applied to a particular apartment building, together with the calculation of the estimated annual energy consumption of flats. For the apartment building project is created in the form of engineering report and drawings.

Welding of socket from C-Mn steel
Boček, Martin ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
Final thesis, elaborated within the master study in the field of Manufacturing technology, deals with analysis and solving of weld cracking problem in welds of anti-roll bar socket for passenger car. Sockets material is fine-grained low-alloy steel S420MC. For better understanding of the problem, a literary study has been elaborated, describing the issue. Next, an analysis of parts material and its weldability, has been conducted, according to ČSN EN 1011-2 standard. After an analysis of cracks and considering current conditions of sockets welding a series of experiments has been designed to evaluate impact of different process parameters on final weld quality. Experiments results have been used to compile a series of recommendations for adjustment of the welding process and to eliminate weld cracking. The results of the experiments were used as a basis for elaboration of WPS protocol.

Web applications for user authentication
Vybíral, Petr ; Dzurenda, Petr (referee) ; Hajný, Jan (advisor)
The thesis deals with the problems of user authentication. The first chapter analyzes the problem of authentication, its methods and its utilization. The second chapter presents the different security options for communication. The chapter describes security, communication and authentication protocols. There is the 2D barcode QR Code described at the end of the chapter. The third chapter is devoted to ASP.NET technology, its development and possibilities of utilization. Attention is focused on web form and server controls. There is an analysis of elements of cookies and possibilities of their use. The last chapter consists of a practical part, which describes the development of a web application. There is a description of the parts of application, such as the database, the Web navigation, master pages and etc. in the following chapter. The cardinal part of the chapter consists of an analysis and implementation of forms authentication, the attribute authentication and authentication with QR code. Finally, there is a description of way how to secure the communication by using a certificate.

Sketchup visualization of statrionery robots
Iutkin, Egor ; Lázna, Tomáš (referee) ; Burian, František (advisor)
Práce je zaměřena na vytvoření jednoduchého vizualizačního nástroje pro robotický manipulátor v softwaru SketchUp. Trojrozměrné rozhraní softwaru se používá k vizualizaci pohybu virtuálního robota pod kontrolou externí aplikace (zpočátku pod kontrolou reálného robota), která využívá sadu protokolů TCP / IP ke sledování polohy robota. Komunikace s projektem ve programu probíhá pomocí SketchUp API rozhraní, které umožnují komunikovat s projektem prostřednictvím zdrojového kódu Ruby. Hodnoty úhlů jednotlivých robotický kloubů jsou interpretovány ve formě parametrický pohyb virtuálního robota. Aplikace klient-server-klient je vytvořena v C++, C# a Ruby pomocí síťových soketů. Sokety se používají k navázání TCP spojení v lokální síti. Plugin Ruby, který poskytuje komunikační rozhraní, v aplikaci se chová jako první klient. Vlastní aplikace C # funguje jako druhý klient, nazývaný „řídicí klient“, poskytuje uživatelské rozhraní pro konfiguraci připojení k serveru a nastavení jednotlivých úhlů kloubů virtuálního robota. Komunikaci mezi dvěma klienty zajišťuje C++ TCP server (konzolová aplikace). Server získává data z řídicího klienta a předává je na stranu Ruby.

Network load generators
Kubík, Pavel ; Koutný, Martin (referee) ; Pelka, Tomáš (advisor)
The aim is to create, test and describe the network load generator for server-client connection type. It´s used language C++ under Linux. It was also used socket and multithreading programming. Load on the server is done by sending HTTP requests. The load generator have different adjustable parameters and displays the test statistics. In this work is described mechanisms wich are used, by the application, to load. Testing was done on one server with a different size of the target file.
