Hlaváč, Martin ; Kuklík, Jan (advisor) ; Starý, Marek (referee)
Constitutional position of Slovakia in Czechoslovakia (1918 - 1992) ABSTRACT (ENGLISH) This thesis deals with the constitutional status of Slovakia within Czechoslovakia in the years 1918 - 1992, i.e. throughout the existence of the common state of Czechs and Slovaks. The work is divided into seven chapters. The first chapter is devoted to the establishment of Czechoslovakia and the period of the so-called First Czechoslovak Republic (until 1938). In addition to the establishment of Czechoslovakia itself, it deals with the agreements of exile representations that preceded it, in more detail the Slovak autonomous movement and the constitutional proposals that emerged from this environment. The second chapter is focused on the position of autonomous Slovakia in the period of the so-called second Czech-Slovak Republic (1938 - 1939), analyzes the actual and constitutional acceptance of Slovakia's autonomy within the Czecho-Slovakia. He pays attention both to the historical circumstances of the adoption of the so-called Žilina Agreement in October 1938 and the Constitutional Act on the Autonomy of Slovakia in November 1938. The third chapter describes the constitutional situation of Czechs and Slovaks during the Second World War (1939 - 1945), briefly deals with the establishment of the Protectorate of Bohemia...

Hlaváč, Martin ; Kuklík, Jan (advisor) ; Kindl, Vladimír (referee)
1 Preparation and adoption of constitutional laws on the Czechoslovak federation ABSTRACT (ENGLISH) The diploma thesis is focused on the preparation of the conception, respective negotiations, and also actual implementation of the federalization of the Czechoslovak state from January 1968 to December 1970. It considers the internal political situation in the context of the state development and of the relations between the federal and national state institutions. I have divided my thesis into five chapters. The first chapter provides brief introduction into development of Czechoslovak constitutional law and Czech-Slovak relations in the period of 1944 - 1967. The second chapter describes in detail negotiations on prepared changes of constitution arrangement, main options which were discussed, process of adoption of respective constitutional law in October 1968 and description of adopted conception of federation. The third chapter deals with realization of Czechoslovak federation, the fourth one is focused on deformation (re-centralization) of federation which resulted in constitutional laws adopted in December 1970. The fifth chapter shortly describes extinction of Czechoslovak federation after Velvet revolution in 1989. Key words: History. Czechoslovakia. Federation.

Side channel attack in cryptanalysis of symmetri and asymmetric schemes
Hlaváč, Martin ; Rosa, Tomáš (advisor) ; Klíma, Vlastimil (referee) ; Tůma, Jiří (referee)
The work summarizes author's three main results during the doctoral studies published at SAC '06 and CHES '09 conferences and the journal IET Information Security. The first two results are the side channel attacks on asymmetric schemes RSA and DSA. They are both based on the theory of lattices and are motivated by modern technologies such as Intel Pentium 4 HTT processor and the electronic passport. The last result is more technology related. It describes the method that provides optical side information and that was empoyed for the first time for the cryptanalytic purposes by the author. As an application, an attack on symmetric cipher AES running on a simple and widespread microcontroller PIC16F84A is presented.

Measurement and anaysis of electrocardiograms
Zimáková, Jana ; Hlaváč, Martin (referee) ; Kolářová, Jana (advisor)
The aim of my barchelor’s thesis was to become familiar with the methology of measurement of electrocardiographic signals, their description and subsequent analysis. During the measurement I used a computer system Biopac and program Matlab. The work is divided into three parts. The first part is focused on general problems of the heart activity, the generation, measurement and description of ECG curves. The second part is devoted to a description of the systém Biopac – recovery, procedure for the measurement and results measured sleep and stress ECG. The third part describes the actual processing of measured signals in Matlab.

Karel Engliš among the Elite of the First Republic
Hlaváč, Martin ; Čechurová, Jana (advisor) ; Jakubec, Ivan (referee) ; Kvaček, Robert (referee)
The main goal of my dissertation is to analyze the personality of Engliš, who was an important representative of the scientific and financial elites during the period of the First Republic. I will venture to explain the causes of his rise during the First Republic and aim to characterize his relations with other elites. The term "elite" refers not only to representatives of the political and financial life of the First Republic, but also to the important leaders of its scientific and cultural scenes. In my dissertation I want to address the relationships between the elite of the First Republic and Karel Engliš. Public opinion played an important role in the relations between Engliš and the elite of the First Republic, in particular as Engliš was presented in the media and how the public perceived him. His family was supportive of Karel Engliš but also caused him many problems. I have found the main material for my thesis in the archive of the National Museum (Archiv Národního muzea), the Literary Archive of the Museum of Czech Literature (Literární archiv Památníku národního písemnictví), the archive of Charles University (Archiv Univerzity Karlovy), the archive of Masaryk University in Brno (Archiv Masarykovy univerzity v Brně) and the archive of the National Bank of the Czech Republic (Archiv...

Postranní útok na RSA-CRT s využitím SFT algoritmu
Ruppeldtová, Ria ; Hlaváč, Martin (advisor) ; Rosa, Tomáš (referee)
The work deals with the side channel attack on RSA using Chinese Remainder Theorem and Montgomery multiplication. The core of the attack lies in finding a Significant Fourier Transform coefficient for appropriately chosen function. In the theoretical part the functionality of SFT algorithm is described and special properties of function coming from the side channel during Montgomery exponentiation in RSA signing are shown. Based on these results a new algorithm for finding a single significant coefficient is proposed. At the end of the work appropriate input parameters are explored and experimentally determined time results of algorithms are presented.

Security Proofs in Symmetric Cryptography
Švarcová, Marie ; Hlaváč, Martin (referee) ; Rudolf, Bohuslav (advisor)
In the present work we investigate into security proofs techniques in symmetric cryptography with aim at authenticated encryption schemes. The results of this area are in each chapter shown and proven. We begin with studying security notions of symmetric cryptography and relations among them. Then we analyze security of authenticated encryption schemes designed by generic composition and introduce keyed hash functions and the NMAC scheme. The last topic we study is an authenticated encryption with associated data. Finally, we describe presented proofs generally and unify the methods used.

Personality of Karel Engliš insight of contemporaries
Hlaváč, Martin ; Štaif, Jiří (advisor) ; Jančík, Drahomír (referee)
The topic of my thesis is "The Personality of Karel Englis as seen by his contemporaries". Only marginally have I touched upon the subject of Englis'scientific work and economist acti vi ties, because I think that they deserve an indi vidual attention, and I have focused primarily on the introduction of Karel Englis through the eyes of his friends, colleagues and family. Karel Engliš was an important Czech economist. Although he came from poor circumstances, he worked his way up to the top of the society in the period of the First republic. He was born on August 17, 1880 in Hrabyň, a small village near Opava. After graduating from Opava' s grammar school he continued his studies at The Faculty of Law at Charles University. During his studies he had to support himself. It was probably the difficult conditions for his studies (actually as well as for the initiation of his "adult" life) which made him a very hard working and persistent person, who followed perseveringly his goal regardless of personal sacrifice. A large number of important roles, which he was successfully performing, is the testimony of it: Minister of Finance, a governor of ČNB, a dean and rector of the Masaryk' s uni versi ty in Brno. His teaching acti vi ties and scientific work at Prague's and Brno's universities frame an important part of...
