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.

Web-based application for cryptographic protocols visualization
Ryšavá, Pavla ; Dzurenda, Petr (referee) ; Ricci, Sara (advisor)
Práce se zabývá vytvořením interaktivní webové aplikace pro substituční šifry a jejich interaktivní kryptoanalýzu. V práci je implementováno šest šifer a zástupci monoalfabetických šifer jsou Caesarova šifra, Atbaš a substituce s klíčovým slovem. Dále zástupci polyalfabetických šifer jsou Vigenrova šifra, Kryptos a Vernamova šifra. Pro interaktivní analýzu je použita frekvenční analýza, index koincidence a n-gramová statistika jako fitness funkce. Výsledek byl dosažen za pomoci HTML5, CSS a skriptovacího jazyka ReactJS což je JavaScriptová knihovna s možností typové kontroly proměnných.
