Web platform for online marketing
Křivánek, Tomáš ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The work focuses on the entire process of developing web application to facilitate the connection between creators of user-generated content and online marketing managers of companies. This marketing industry is relatively new in the Czech Republic, and there are currently no platforms that simplify the interaction between these mentioned participants. The development process begins with a careful collection and analysis of the requirements of potential users of this new system. Based on the gathered requirements, the system architecture is then designed using modern technologies. For the system development, a backend in the form of a REST API is chosen, programmed using the Python FastAPI framework. Additionally, the Vue framework will be utilized on the client side. Data storage will involve MySQL and MongoDB databases, along with a cloud storage solution. After the selection of specific technologies, the implementation of the system is described, as well as how the testing of the whole application was carried out.

Use of blockchain technology for recording changes in cloud storage
Spolek, Jaroslav ; Malina, Lukáš (referee) ; Dzurenda, Petr (advisor)
The bachelor’s thesis focuses on the design and implementation of a module to ensure data integrity on an existing cloud storage platform, Nextcloud. The theoretical part deals with issues related to the security of cloud storage services, and subsequently, it provides a general introduction to blockchain technology and its implementation in the form of Ethereum blockchain technology. Included are the basic principles of Ethereum blockchain technology and the principles of smart contracts. In the practical part, the design proposal, tools used during the implementation, and the implementation of the data integrity module utilising blockchain technology are presented. The results of the system testing are then analysed, and external influences and factors affecting the cost and operation of the module are identified. This analysis concludes with a proposal for future improvements addressing the current shortcomings of the module.

Cloud storage secured with post-quantum cryptography algorithms
Kačírek, Tomáš ; Sikora, Marek (referee) ; Člupek, Vlastimil (advisor)
This bachelor thesis deals with cloud storage secured by post-quantum cryptography and its practical implementation. The theoretical and mathematical principles of post-quantum algorithms are presented. Furthermore, their possible implementations according to security requirements and libraries that work with these algorithms are discussed. Tests have been performed to determine the most efficient algorithms for ensuring two-party authentication, confidentiality and data integrity. Then the cloud and what advantages or vulnerabilities it has was discussed. The selected algorithms were then used in a practical implementation of cloud storage in a LAN.

Long-term Cloud Storage Security
Wojnar, Filip ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
Práce se zaměřuje především na téma dlouhodobé bezpečnosti archivních úložišť v cloudu. Zabývá se podmínkami a zásadami životního cyklu správy klíčů, které uvádí NIST pro vytvoření robustního systému správy klíčů. Závěrečná část úvodní kapitoly zkoumá nejnovější možnosti systémů správy klíčů, zahrnující průmyslové giganty, jako je Amazon Web Services Key Management Services, až po open-source alternativu s názvem Hashicorp Vault. Druhá kapitola práce je věnována postkvantově bezpečné kryptografii a zkoumá proces standardizace NIST pro postkvantovou kryptografii (PQC). V rámci této oblasti práce porovnává sedm algoritmů, které úspěšně prošly do závěrečného kola zvažování, a nakonec vybírá Crystals-Dilithium pro Digital Signature Algorithm (DSA) a Crystals-Kyber pro Key Encapsulation Mechanism (KEM) jako nejefektivnější na základě procesorového času, který vyžadují pro své kryptografické operace. Třetí kapitola nastiňuje stávající cloudový archivační systém na VUT v Brně a navrhuje výchozí kryptografické schéma pro správu klíčů ve virtualizovaném prostředí. To zahrnuje generování páru master klíčů, generování páru datových klíčů, šifrování dat v klidu, dešifrování dat v klidu, sdílení prostředků, rotaci klíčů, obnovu klíčů a odvolání klíčů. Čtvrtá kapitola se zabývá nuancemi implementace realizované v této práci a hodnotí efektivitu řešení pomocí benchmarků zaměřených na nově přidanou kryptografickou funkcionality realizovanou pomocí post-kvantově bezpečné správy klíčů.

Sports Manager for iOS
Hort, Jaroslav ; Smrčka, Aleš (referee) ; Hrubý, Martin (advisor)
This work discusses design, implementation, connection, testing and practical use of mobile application for iOS and supporting web application. I have analyzed the effects of music to sport and designed and implemented a fitting mobile application allowing users to collect data from their activities, music players and see the effects of music on them. During design and implementation, I have emphasised usability, expandability and synchronization with cloud storage, for this reason I have created a web application, allowing users to monitor their results captured from mobile anywhere.

Cloud Storage Integration into Web Applications
Studnička, Ondřej ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
The aim of this thesis is to analyze selected cloud storages and their APIs. The practical use is demonstrated in web application that is used for to create dynamic presentation based on Reveal.js framework. The application allows user to save the created presentation to selected cloud storage. Supported storages are Google Drive, Dropbox, Github and Gitlab. The application is implemented using Vue.js. The theoretical part of the thesis focuses on the possibilities of creating web applications according to current trends. The practical part describes the implementation and testing of the created application.

Advanced Filtering of Digital Evidence
Chudáček, Ondřej ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
This thesis focuses on the implementation of advanced filtering of digital evidence stored on an open source cloud storage NextCloud. The contents of the thesis are law analysis regarding the storage of digital evidence in NextCloud, design of NextCloud, homomorphic encryption and its possible usages, attribute based searchable encryption and its usages and implementation of a simple stand-alone filtration client. Experts on digital evidence were asked about the choice of filtration criteria as a part of the thesis. The key feature of the thesis is a description of implementation of filtration inside NextCloud which has been extended to contain five new filtration criteria. The result has been submitted to performance and functional tests.

Framework for a Web Internet Service Implemented in Google Cloud Platform
Roshka, Andrei ; Smrčka, Aleš (referee) ; Hrubý, Martin (advisor)
Cílem této bakalářské práce je navrhnout a naimplementovat rámcové řešení pro placenou internetovou službu a nasadit ho na cloudové služby poskytované Google Cloud Platform s nejnižší provozní cenou. Výsledná architektura je serverless a používá služby Firebase jako Firestore NoSQL databáze, Firebase Storage a Firebase Authentication. Rešení je psáno v jazyce TypeScript a skládá se ze dvou hlavních cásti - front-end aplikace a pracovního procesu, který zpracovává výpočetní úlohy. React se používá k vytvoření uživatelského rozhraní založeného na komponentách spolu s Reduxem pro centralizovanou správu stavu aplikací. Jako server pro front-end se používá Nginx. Pracovní proces je postaven na Node.js - serverovém prostredí pro JavaScript. Aplikace je úspešně nasazena do servisy Cloud Run jako sada Docker kontejneru za použitím CI/CD pipeliny postavené na Cloud Build.
