Web application for file encryption
Tatar, Martin ; Blažek, Petr (referee) ; Zeman, Václav (advisor)
The bachelor thesis is focused on developing a web application for file encryption. In the theoretical part symmetric encryption algorithms are divided into block ciphers and stream ciphers. Selected ciphers are described and their properties are compared. Then the modes of operation for block ciphers are described. The developed application encrypts both files and text inputs by the selected algorithm and can operate in various modes of operation. In addition to this functionality the application is supplemented with descriptions of available ciphers and modes of operation.

A portal to support the teaching of applied cryptography
Vojáčková, Veronika ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
Cryptography has a rich history, ranging from ancient civilizations to modern times, ensuring confidentiality and security has always played a very important role. In order to understand these algorithms, however, it is necessary to understand the basics of this issue, which can be a very difficult task without comprehensive resources. The thesis first examines web portals dealing with cryptography on the Czech and foreign Internet. Next, it compiles all the necessary knowledge for the subject of applied cryptography. As part of the work, a web portal is created bringing together the necessary information to support teaching along with a practical demonstration of algorithms and their use in the Python programming language.

Mode Change in Real-time Component Systems
Outlý, Matěj ; Bureš, Tomáš (advisor) ; Malohlava, Michal (referee)
The goal of the thesis is to examine possibilities of dynamic reconfiguration in real-time component systems, especially to formally describe support of operating modes. The thesis introduces a reconfiguration mechanism based on properties and relations between them. The mechanism is designed to facilitate a straight forward modeling of operating modes and reconfiguration rules and preserves re-usability of assembled components. The thesis also presents a realization of the mechanism suitable for the domain of embedded real-time systems.
