Security and Privacy in IoT
Utěkal, Josef ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
The bachelor's thesis deals with the topic of security and privacy in the field of Internet of Things (IoT), for which resource constrained devices are typical. It is very important to find a suitable operating system that, in addition to low computational requirements, would also offer the desired functionality for these constrained IoT devices, such as real-time capabilities. OS RIOT seems to be the one for IoT. It enables you to run applications written in C language on any supported hardware -- in this bachelor's thesis specifically on Arduino Uno and Arduino Due. The thesis also describes several cryptographic libraries that are supported by OS RIOT. The aim is to implement selected cryptographic libraries and measure their computational and memory requirements on both Arduino devices. This is preceded by a theoretical and practical familiarization with OS RIOT, which is realized by creating the first project, and measuring the computational complexity of each cryptographic function of the WolfSSL library on the Raspberry Pi 4 Model B.

Bezpečný model elektronického obchodování a jeho ekonomické
Fotijev, Pavel ; Smejkal, Vladimír (advisor)
The purpose of the presented dissertation thesis is to contribute to the development of the theory of electronic commerce in complex conditions of „network economy“ by the partial consolidation and integration of the highly fragmented existing knowledge and ideas, i.e. to offer more compact conceptual framework, based on research of the current state of knowledge and situation in the conditions of the Czech Republic. The thesis is focused on the contemporary theoretical knowledge analysis from the areas of interest concerning the electronic commerce security, used models of electronic shops and evaluation of its economic aspects, which this type of business bears. Next contribution is unification of this knowledge and creation of the conceptual base for the ongoing recognition and theory building related to electronic commerce. The work is also focused on the area of electronic cash, possible solution of some diversifications in payment transactions. On the practical level the author attempted to narrow the knowledge “gap” in the empirical cognition of the doctoral thesis issues concerning the effectiveness of electronic commerce and generally e-commerce applications. Proposed return on investment calculation methodology applied to e-commerce area may help managers making decisions in investing to these projects.

Stabilizing systems of passenger cars
Odehnal, Jakub ; Vopařil, Jan (referee) ; Kučera, Pavel (advisor)
This Bachelor’s thesis describes basic stabilizing systems of passenger cars. These systems are correcting driving the cars and improve safety of the traffic. The main systems described in this thesis are ABS, ASR and ESP. There are also summarized some other assistant systems. In the end there is also view of various individual car companies and their theories of stabilizing of cars.

Web Services Security for a Service Consumer
Novotný, Petr ; Weiss, Petr (referee) ; Rychlý, Marek (advisor)
The objective of this project was to introduce to a reader different possibilities of a web security and its authentication. Another part of this project was to create a client application communicates with the web service. The client part should at the some time serve the web services developer for checking chosen web securities.

Home Security and Monitoring System
Valach, Lukáš ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The thesis elaborates on an implementation of wireless home security system. The wireless communication utilizes IEEE 802.15.4 radios and ZigBee communication protocol. The beginning of the thesis provides specification of the intended system followed by an evaluation of usable energy harvesting solutions and later by consideration of single board computer systems suitable for implementation of the control node of the sensor network. The rest of the thesis describes design, implementation and testing of particular components of the security system. Conclusion evaluates the achieved goals and offers suggestions for future work. The end products of the thesis are physical devices implementing wireless sensor nodes, control unit of the security system as well as a graphical user interface for the system management.

Secure data transmition using bar codes
Kratochvíl, Martin ; Herout, Adam (referee) ; Beran, Vítězslav (advisor)
The goal of this thesis was to create a system for visual data transmition using bar codes. It focuses mainly on the protection of the system against abuse. A mechanism was designed for the data transmition itself and the various security concepts. The most appropriate bar code for data transmition was selected on the basis of the analysis.
