Demonstration of Cryptographic Problems through an Interactive Educational Game
Fišarová, Anežka ; Mezina, Anzhelika (referee) ; Mikulec, Marek (advisor)
The bachelor thesis is focused on the design and implementation of a cryptographic interactive educational game. It focuses on various cryptographic ciphers specifically selected so that people outside the field can be introduced to the subject in a demonstrative and entertaining way. Java and JavaFX were used as the programming language. The thesis consists of four parts, the first two are oriented towards the theoretical part of cryptography and the second two are more focused on the practical application and code development. As motivation for the players, a score for correctly cracked ciphers was used. Furthermore, the work includes a choice of difficulty, which influences which ciphers will be presented to the players. At the end of the thesis, the author reflects on the results and explores ways to further improve the methods presented.

Library of Algorithms for Text Ciphering
Mikulka, Jiří ; Havel, Jiří (referee) ; Kubíček, Radek (advisor)
This thesis brings an overview of historical and modern methods and approaches used in cryptography. It also describes and assesses ciphers, which have been used since the very beginning of encryption till modern ciphers. Based on information resulting from this overview the reader should be able to distinguish between ciphers, know their advantages and disadvantages, and be able to choose the best cipher for any purpose. Ciphers mentioned in this thesis are implemented in a library called CipherLib , which shows usage of every described cipher.

Software support of education in classical cryptoanalysis
Fojtová, Lucie ; Hajný, Jan (referee) ; Burda, Karel (advisor)
Number of today's modern cipher systems are based on the classical symmetric cipher systems, such as the transposition principle in the DES cipher. Successful analysis and deciphering of these ciphers is therefore underlined by solid knowledge of the elementary cryptanalysis methods. This implies the importance of classical cryptanalysis education -- for better a understanding of the field, using visual means is of utmost importance. The aim of the thesis is to summarize selected cipher methods of the classical cryptanalysis, namely the mono-- and polyalphabetical substitution and transposition route cipher. Along with the theoretical part, ciphering/deciphering software is introduced to be used for educational purposes, particularly a website and a standalone application providing tools for ciphering, analysis and code breaking of the classical cipher based code.
