Realization of differential power analysis
Marek, Pavel ; Dzurenda, Petr (referee) ; Martinásek, Zdeněk (advisor)
Nowadays, it is not enough to pay attention to encryption algorithm security from the mathematical aspect only. It is also necessary to pay attention to the implementation of encryption algorithm, because encryption devices can show plenty of information about implemented encryption via undesirable communication. This bachelor thesis deals with side channels issues (especially power side channel) and their use to obtain the secret key of AES encryption algorithm. For this purpose there are three operations realized in this thesis. At first, there is experimental workplace designed, which provides automatic saving of waveforms of encryption. Then there is a simple and differential power analysis of these waveforms performed. All parts are theoretically described in individual chapters. After theoretical description there is the practical part, which describes a proper realization of all tasks.

Implementation of Smart Factory
Marek, Pavel ; Krajsa, Ondřej (referee) ; Škorpil, Vladislav (advisor)
This diploma thesis is focused on the study of concept of Internet of Things, concept of Industry 4.0 and on current conditions in smart factories. Based on these studies there was designed and implemented hardware and software adjustment for industrial machines and connection of these industrial machines to communication network. There was designed and programmed the application in the C# language. This application provides a data collection from industrial machines, provides various services for machines and humans and this application is processing and viewing necessary data. For these purposes the application is using a database system based on the SQLite. These tasks of designing and implementation are summarized to system, which is determined for smart factory implementation. This implementation is created according to Industry 4.0 concept.

Measurement of Transfer and Immittance Characteristics of Active Circuit Elements
Marek, Pavel ; Vrba, Kamil (referee) ; Kubánek, David (advisor)
This diploma work deals with active circuit elements and proposals of methods for measuring of some parameters of these elements. In the opening part the work deals with general classification of elements used in electronic circuits, ideal and real current sources and power supplies. Further there are stated basic parameters and characteristics presented by producers in a catalogue sheet for active elements MAX435, OPA660, AD844 and MAA741 element which already belongs to the history of IC. Main attention is paid to active circuit elements with current sources driven by CCCS (Current Controlled Current Source) and AD844 (high speed monolithic operational amplifier). In the work there is described a method for determining of selected parameters of active elements with CCCS. Examined parameters were frequency characteristics of current transfer, input impedance and output impedance. The proposed method was verified by a computer simulation on above mentioned active elements by means of PSpice software. Findings along with the description are summarized at the end of the work. In the closing part of the work there is undertaken a real measure of AD844 element based on the proposed method and the findings are compared with particular simulations. However, at first a flat connection board was made by means of EAGLE software and then the measure was performed on it.

Secure Communications in Wireless Embedded Systems
Marek, Pavel ; Šimek, Milan (referee) ; Červenka, Vladimír (advisor)
This bachelor thesis deals with secure communication in wireless sensor networks. There are given and described options of encryption protocols that using symmetric and asymmetric ciphers. This protocols are evaluated from aspect of computational performance and energy comsumption. Pursuant this evaluations there is designed and implemented key distribution protocol for symmetric cipher. Encryption of communication s implemented by IEEE 802.15.4 standard. This implementation is performed on ARM Cortex-M3.

Spanish Embassy in Prague under don Baltasar De Zúñiga (1608-1617)
Bardoňová, Martina ; Šedivá Koldinská, Marie (advisor) ; Kubeš, Jiří (referee) ; Marek, Pavel (referee)
The present work is a contribution to the history of the Early modern diplomacy and early modern diplomatic practics. The subject of this work is the diplomatic misson of Baltasar de Zúñiga at imerial court (1608-1617). The study focuses on description of embassy functioning based on an analyses of official documents produced by the embassy itself, which were in several instances complemented by some of the documents produced by the Spanish governmental bureucracy such as, instructions, credentials, consultas or correspondence addressed to the hands of ambassador Baltasar de Zúñiga. As such, the present study is a kind of introspection, because it shows the functioning of a diplomatic mission from inside. The aim is to aswer the following questions. What part of the day-to-day work of a specific embassy could be seen, and controled by a sending government. How the chosen sources represent the basis of the Spanish policy in the Holy Roman Empire, the instruments used to increase the reputation of the Spanish king and the reputation of the ambassaror himself.

ALTREP Data Representation in FastR
Marek, Pavel ; Šindelář, Štěpán (advisor) ; Horký, Vojtěch (referee)
R is a programming language and a tool used mostly in statistics and data analysis domains, with a rich package-based extension system. GNU-R, the standard interpreter of R, in version 3.5.0 introduced a new native API (ALTREP) for R extensions developers. The goal of the thesis is to implement this API for FastR, an interpreter of R based on GraalVM and Truffle, and explore options for optimization of FastR in context of this API. The motivation is to increase the number of extensions that can be installed and run on FastR. 1

Spanish-Dutch relations in the New World during the existence of the West-Indische Compagnie
Kubátová, Eva ; Křížová, Markéta (advisor) ; Skřivan, Aleš (referee) ; Marek, Pavel (referee)
Spanish-Dutch Relations in the New World during the Existence of the West Indische Compagnie Eva Kubátová Abstract This dissertation is dedicated to the Spanish-Dutch relations in the New World during the existence of the first Dutch West India Company (1621-1674). On base of an imagological analysis, this thesis presents elements of mutual relations, reflected in hetero-images, together with self-representation of both analyzed parties (thus self-image) within the ongoing conflict of the Eighty Years' War. The imagological analysis is applied on archival material, chiefly the Dutch pamphlets and Spanish Relaciones de sucesos (which can be translated as "Treatises of Successes"). The result of this thesis is then an analysis of development and changes of mutual images, upon the historical events of the Spanish-Dutch war conflict: thus since the beginnings of the Dutch Revolt, passing through the Twelve Years' Truce, until the signature of the Peace of Westphalia in 1648. A special emphasis is put to the final phase of the Eighty Years' War, in this thesis delimited by the years 1621-1648, which was marked by the official entrance of the West India Company into the Spanish waters of Greater Caribbean. An important watershed in mutual relations is afterwards represented by the Peace of Westphalia, which...
