Authentication using mobile application and BLE technology
Žigrai, Martin ; Ilgner, Petr (referee) ; Dobiáš, Patrik (advisor)
The main idea of this bachelor's thesis is the design and development of a cross-platform mobile application. This mobile application is intended for vehicle reservation and authentication for accessing the vehicle. The goal of the application is to provide a simple and reliable environment for users to quickly and easily search for and reserve a specific vehicle. The mobile application communicates with the vehicle using BLE technology. To ensure the security and confidentiality of communication, cryptographic primitives such as AES and SHA have been utilized. The bachelor's thesis includes an overview of mobile application development, development tools, an overview of cryptographic primitives, and Bluetooth technology. Another part is the design of the mobile application, an overview of cryptographic libraries in Flutter, and the implementation of the mobile application.
Access control system for carsharing application
Texl, Filip ; Ilgner, Petr (referee) ; Dzurenda, Petr (advisor)
The bachelor thesis is devoted to access systems with an emphasis on carsharing applications, both from a theoretical point of view, where it analyzes their advantages and disadvantages and uses cryptographic primitives, and also from a practical point of view, where the practical part includes the design of an access system and its subsequent implementation. Bluetooth Low Energy technology and Near field communication are also used in the bachelor thesis, which is again described from a theoretical point of view, especially the key concepts of these technologies, as well as its practical use for access systems.
Mobile application for victims of bullying
Vlachová, Monika ; Ilgner, Petr (referee) ; Martinásek, Zdeněk (advisor)
This thesis aims to define the concept of bullying, its division, participants, consequences and possible solutions or prevention. It also provides a summary of the concept of bullying from a legal perspective. All this is important for understanding the insidiousness of bullying and the reason for creating this thesis. Furthermore, the general Android application development, architecture, mobile application development environment, tools, and basic steps are discussed. A graphical concept of the actual app design is shown and the implementation of the app in the Android Studio environment is described. Finally, user tests are processed and analysed.
Fuzzer Based on Genetic Programming
Závada, Tomáš ; Gerlich, Tomáš (referee) ; Ilgner, Petr (advisor)
The thesis is focused on testing, discusses its various approaches and more specifically focuses on the automated testing technique called fuzzing. Theoretical part is focused on the process, used in fuzzing, advantages and disadvantages and also some of possible improvements. Furthermore, the work is focused specifically on improving the process of fuzzing using genetic algorithms. Genetic algorithms help create more appropriate test inputs, saving time during testing process while achieving appropriate results. A server using the DLMS/COSEM standard was chosen as the testing target. The thesis also introduces the DLMS protocol, which provides communication between clients and servers, and other essentials falling under the COSEM specification. Then the assembly of a test network, containing a server and a client, which use the mentioned standard for communication, is described. The thesis also elaborates a solution proposal for how the connection of the testing tool in the network could look like in a generic case. Finally, the implementation of a fuzzer using genetic algorithms to generate test data is also included.
Stress Testing of Video Streaming Services
Kříž, Petr ; Ilgner, Petr (referee) ; Číka, Petr (advisor)
The bachelor thesis deals with the load testing of services for adaptive streaming of multimedia content. The thesis starts with a theoretical discussion of load testing and standards for adaptive streaming. The practical part deals with the creation of scenarios for load testing the created streaming server. Finally, graphs are prepared including commenting on the testing result.
Cryptography and security on the MultOS platform
Lidmila, Aleš ; Ilgner, Petr (referee) ; Dzurenda, Petr (advisor)
The bachelor thesis deals with the development of a security IoT system for user authentication using the MultOS platform. It also deals with the development and descriptionof a publishing system that manages MultOS endpoints.
Application for volunteer fire department
Vopálka, Matěj ; Ilgner, Petr (referee) ; Gerlich, Tomáš (advisor)
The thesis deals with the development of a web application for volunteer firefighters. The application allows a firefighter to respond to the incident notification and display the status of individual members on the monitor in the fire station. The aplication provides user authentication and allows the viewing of information about the incident, including participating firefighters. The application receives incident information via the web application interface from Raspberry Pi, which reads and formats SMS messages.

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.
Stress Testing of Internet Telephony
Šípek, Martin ; Ilgner, Petr (referee) ; Číka, Petr (advisor)
The thesis deals with the development of a module for JMeter that adds SIP stress testing functionality that was previously missing in the program. The theoretical part of the thesis deals with Internet telephony and codecs used in telephony. The SIP protocol is discussed in detail and the end of this part is devoted to stress testing. The practical part focuses mainly on the development of the proposed module, where the code of the module is described in detail, but it also deals with the installation and configuration of the Asterisk PBX on which the proposed module is tested. The results of this testing are analyzed at the very end of this thesis.
