Web Application of Authentication System
Nohava, Martin ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
The subject of the bachelor thesis is the design and development of graphical-user interfaces for cryptographic protocols using web technologies. Specifically, it adds the possibility to control the PEAS authentication system through web interfaces. The thesis first evaluates the contemporary possibilities of modern web applications and pays attention to the issue of interconnecting web technologies with authentication system created in C programming language. For this purpose, the work also focuses on the Webassembly technology. In the practical part, four graphical user interfaces were created, one for each entity of the authentication system. They are built on web technologies such as HTML, CSS and JavaScript, utilizing the Vue.js framework. Communication with the authentication system provides the developed web servers. They are using API and run in the Node.js environment.

Ensuring Long-term Data Integrity in Cloud Storage
Nohava, Martin ; Člupek, Vlastimil (referee) ; Malina, Lukáš (advisor)
The subject of the thesis is the design and development of a system to ensure the long-term integrity of data from the Nextcloud cloud storage, which manages and stores electronic evidence. In the introductory part, the terms and principles used for securing data integrity are presented, including quantum-resistant digital signature schemes. Subsequently, the architecture of the archiving system and the method of its connection with the Nextcloud cloud storage are proposed. The resulting system consists of two main components, the Archive application, which extends the web interface of the Nextcloud instance, and the archiving system, which ensures the integrity of the archived files themselves. In addition to time stamps, system also uses a quantum-resistant Dilithium signature scheme. At the end of the work, an evaluation of the implemented solution is carried out by measuring the performance of the archiving system, and options for its further development are proposed.
