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.

Performance tests of cryptographic algorithms
Pospíšil, Karel ; Martinásek, Zdeněk (referee) ; Sobotka, Jiří (advisor)
Bachelor's thesis deals with analysis of the various cryptographic algorithms that are used for securing communications. The first part is devoted to symmetrical cryptographic algorithms, asymmetric cryptographic algorithms and hashing functions. The second part deals with the security classification and attacks that are used to attack cryptographic algorithms and hash function. The third part deals with the selected testing algorithm RC4 and MD5 hashed function for using CrypTool. The final section provides an evaluation and test results of algorithm RC4 and MD5 hashing function.

The Study Entering Production Task Selected Technology
Holík, Radim ; Pospíšil, Karel (referee) ; Jurová, Marie (advisor)
This bachelor thesis is focused on chosen contracts processes through the company. A fault appears at one of the crucial workplaces, that expressively influences the finalization term and the final costs amount. Creation of the proposal for new contract processes counting this fault is the solution of the thesis. The thesis is processed in TOS KUŘIM – OS, a. s. company, where are collected information and bases. Next basis work on theoretical presumptions of specialized literature and practical experiences.

Obstacles and opportunities for implementation of sustainable development principles in transport in the Czech Republic
Tym, Antonín ; Moldan, Bedřich (advisor) ; Nekola, Martin (referee) ; Pospíšil, Karel (referee)
The main topic of the thesis is actors and their role in the policy change process in the transport policy of the Czech Republic. It is argued that current transport system is not sustainable and the main goal of every transport policy should be sustainable transport. There exist, however, many barriers in achieving more sustainable transport system. Institutional barriers including formal organisations as well as norms and rules and actors seem to be one of the most significant. These actors can influence and change policy. One of the theories explaining how actors can change policy is the Advocacy Coalition Framework (ACF). The ACF suggests that actors form their policy proposals and solutions according to their belief system and create advocacy coalitions in order to pursue their goals and interests. A policy changes when a dominant coalition has been replaced by so far minor coalition representing policy alternatives or when a dominant coalition members change their attitudes towards, or a perception of, a given policy problem (e.g. local transport). Therefore, the main aim of the thesis is to find out how selected actors perceive problems of the transport policy in the Czech Republic and to identify potential advocacy coalitions through analysis of their attitudes. One of the objectives is...
