Cryptographic schemes implementation on small FPGA platforms
Pukšová, Ráchel ; Cíbik, Peter (referee) ; Dobiáš, Patrik (advisor)
The objective of the bachelor thesis is to implement the AES-GCM encryption algorithm on a Nexys A7-100T FPGA board. It introduces the issues of cryptography and authentication in data transmission as well as describes the FPGA technology. The implementation has been done in VHDL, as a hardware description language. It analyses the project provided by the Institute of Telecommunications of Brno University of Technology, which is intended to be modified to achieve the stated goal. In the practical part, it discusses the modifications made and the tests that verified the functionality of the implementation. It compares resource utilization with the original project as a tool to better understand the impact of the modifications made. This work is also compared with existing AES-GCM solutions. Finally, suggestions are given for further modifications that could be made to achieve lower goals.

Beam Shaping Circuits for L Band Antenna
Kalina, Ladislav ; Pítra, Kamil (referee) ; Urbanec, Tomáš (advisor)
This thesis contains design of beamforming network designed for passive radar antennas. The first part contains theory of passive radars and beamforming networks. The next part implies design of beamforming network at the block digram level. Then are choosed circuits for amplitude and phase control, including the design of control communication. It follows by realization of IQ phase shifter and his automatic measurement. Based on this results is phase shifter adjusted and PCB of 2x2 beamforming network is designed. Last part includes design of control application (Matlab) and control program for STM32F407VG microcontroller.

3D Volume Rendering Data Visualization
Němeček, Pavel ; Kubíček, Radek (referee) ; Kršek, Přemysl (advisor)
The first part of this project is focused on theoretical analysis of methods for rendering volume data. Both methods are analyzed showing the volume data using triangle mesh, and methods for direct volume rendering. Ray Casting is presented in detail. Possible way of its realization using graphics card is the subject of implementation part. The paper presents several methods that could be applied to ray casting and achieve different results of visualization of the same data. The work also aims to create a graphical user interface that allows interactive visualizations.
