Smart Card side channels
Pospíšil, Karel ; Martinásek, Zdeněk (referee) ; Sobotka, Jiří (advisor)
The thesis is dealing with smart cards and describes the known types of side channel attacks. Smart card belongs into the group of the youngest and smartest cards. In the card body, made mostly from PVC, there is a chip inserted which contains a microprocessor.Side channel attacks are trying to use the leaking information from the physical implementation of the system while processing the cryptographic algorithm. The attacker is trying to use the leaking sensitive information because under certain circumstances it can be dependent on the input data. The theoretical part is devoted to description of smart cards, their types and their safety. It describes the classification of attacks on smart cards and includes the overview of selected cryptographic algorithms used in smart cards. It also describes selected physical and logical attacks and the most frequent side channel attacks. The thesis furthermore describes possibilities of measuring the voltage-current side channel. The practical part deals with used software and hardware. This section is devoted to the measurement of power specification of smart cards and to the analysis of processed information, using the oscilloscope and workstation with AD 622 card and Simulink development environment.

Engine simulator - HW development
Starosta, Michal ; Hutyra, Tomáš (referee) ; Klusáček, Stanislav (advisor)
STAROSTA, Michal . ENGINE SIMULATOR – HARDWARE SUGGESTION. Bachelor’s thesis. Brno: University of Technology, Faculty of electrical engineering and communication, 2009. 51 s., Supervisor.: Ing. Stanislav Klusáček. This work describes suggestion of concept of simulator of jet egine for purposes of testing control unit for this engine FADEC. There are described possibilities of software and hardware facilities for simulator realization. Possibilities of software facilities are mainly focused on Matlab / Simulink program to communicate in real time with card for data acquisition.

Electronic throttle
Dušek, Jiří ; Beran, Martin (referee) ; Havlíková, Marie (advisor)
The aim of this master’s thesis was to analyze the contemporary electronic throttles and the requirements imposed on them. Then to build the mathematical model, identify parameters of the given electronic throttle, proceed the verification and on its basis to build the simulation model. There were selected suitable control and high power components to control the electronic throttle. Due to the knowledge of these parameters the simulation model was extended. For this extended simulation model was designed the position cascade controller with speed and current control loop. Using the designed controller the implementation of the electronic throttle control and the available high power and control module was realized.

Laboratory tasks for Feedback 38-001
Gléba, Gergely ; Veselý, Libor (referee) ; Blaha, Petr (advisor)
The aim of this project was to get acquainted with the preparation Feedback 38-001, regenerate and establish several demonstration tasks. The first part deals with the description and the resurgence of the device. The second section describes the activities of modernization and innovation the teaching facilities. The main care was to focus on the implementation of connection with the computer supplementing measuring card and obtaining information of the regulation in real time. The third part includes the proposed laboratory tasks. The first task is based on the on-off control, which is mostly used in practice for its ease of use, with no major claims. The second task is defined for continuous control, which ensures better quality and comfort of controlling the level and the water flow. The third contains a task for identification of system parameters.

Design, production and testing of education model "Watt's regulator"
Janoš, Petr ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
In the thesis I deal with design, production and testing of laboratory education model "Watt‘s regulator". This work considers different solutions of construction and especially the role of sensors. I assess positives and negatives of each solution. In addition, I describe design and implementation of electronics and wiring for the communication with a PC via control card Humusoft MF624. Using the MATLAB-Simulink and its extensions Real Time Toolbox 4.0 I make the proposal of PID regulator based on Ziegler – Nichols method.

Real time signal processing
Nepovím, Pavel ; Rášo, Ondřej (referee) ; Mlýnek, Petr (advisor)
The aim of the master’s thesis is to acquaint the reader with Discrete Fourier Transform DFT and its introduction to spectral analysis descrete time signals. Furthermore it describes efficient computation of the DFT using the algorithm Fast Fourier Transform FFT and effects that appear in the DFT spectral analysis, the effect of the length of the DFT, the effect of the length of the segment of the analysed signal and the leakage. Next is explained the issue of the complex representation of real bandpass signals in the baseband, called the complex envelope of signals. This represenation uses the Hilbert Transform and the analytic signal. The thesis also describes the application library Real Time Toolbox of the software Matlab/Simulink, that uses the data acquition card AD622 allows to connect and process real signals in real time. In Matlab/Simulink with use this facilities is create the laboratory lesson, that simulating the complex represenation of real bandpass signals in real time.
