Honeypot for LoRaWAN protocol
Zhukova, Viktoriia ; Pospíšil, Jan (referee) ; Pospíšil, Ondřej (advisor)
The bachelor’s thesis in the theoretical section focuses on LoRaWAN technology. It describes network communication, LoRaWAN security, vulnerabilities, and mitigation measures. The second half of the theoretical section focuses on describing honeypot technology and its distribution, listing its advantages and disadvantages, and comparing IoT honeypots. The practical section focuses on building an experimental environment. There is a description of the selected hardware and software. It describes the commissioning of the LoRaWAN network, the configuration of the gateway, and the startup of the LoRaWAN server. Next, the whole procedure of honeypot assembly is described. Two variants of high-interaction honeypot are described and investigated. One without the use of sandboxing and using a firewall, the other with the use of sandboxing and an implementation of chroot/jail.

Wireless Sensory Network Using LoRa Technology
Mikulášek, Michal ; Pokorný, Jiří (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis focuses in the first half on the Internet of Things and the available wireless technologies for the Internet of Things. Each technology is characterized by its features, pros and cons, as well as the possibilities of using it in the Internet of Things. In the second half of the thesis, a practical design and construction of a LoRa network, consisting of a sensory and a central unit, is carried out. The parts of the solution are designed wiring schemes, printed circuit boards and detailed photo documentation. Additionaly the software solutions for both types of units are described, with detailed descriptions of the proposed features. The maximum possible range is tested and documented for the entire solution. Subsequently, a detailed measurement of the power consumption of the sensor unit is carried out and an extensive estimation of its battery life for a selected battery.

Design and Performance Analysis of Parallel Processing of SRTP Packets
Wozniak, Jan ; Zbořil, František (referee) ; Jurnečka, Peter (advisor)
Šifrování multimediálních datových přenosů v reálném čase je jednou z úloh telekomunikační infrastruktury pro dosažení nezbytné úrovně zabezpečení. Rychlost provedení šifrovacího algoritmu může hrát klíčovou roli ve velikosti zpoždění jednotlivých paketů a proto je tento úkol zajímavým z hlediska optimalizačních metod. Tato práce se zaměřuje na možnosti paralelizace zpracování SRTP pro účely telefonní ústředny s využitím OpenCL frameworku a následnou analýzu potenciálního zlepšení.

HOUSE ON THE FOOTHILL - TOWN HOUSE IN THE HISTORICAL CENTRE
Veselá, Marie ; Rudiš, Viktor (referee) ; Oplatek, Jiří (advisor)
Potential sites lies not only in its location but also the dominant position it holds to their surroundings. Undeveloped plot represents a "node" or "island" ... loosening strictly linear character Bakery. It is a place which brings together three disparate streams - Classical serious at the running part of Mendel Square, dramatically quarreling upper section flowing into the area from Hus class and insignificant Anenská that, if there "just got lost." All "three" street, however, are closely connected with the plot and the transformation of space clearly indicates their transformation. A distinctive feature of the property is its visual exposure of looking from Mendel Square, the plot creates a "picture" to which the pawn closer. This image should be interesting, changing to attract one's attention for more than just one or two seconds. The image should not least communicate - what is happening on the ground, what links are individual objects ... a landmark and should, for use by infantrymen use. It should also not be attractive from a distance - when one zooms in close proximity, should be surprised by the discovery of something new, something that was not noticeable from a distance, it should be attention to detail, or idea that can be seen only at close contact.

Conservation Area Kroměříž - architecture–urban design of the selected site
Dočekalová, Pavla ; Vojtová, Lea (referee) ; Hrabec, Josef (advisor)
The master's thesis describes the design of urban interior street Vejvanovského in urban conservation Kroměříž and operational and functional adaptations street stalls in the context of surrounding roads and spaces. As part is design of architectural studies for three new objects. Objects respond to the needs, space, matter, and the street and the surroundins. The plots of selected street is designed gallery, hotel with restaurant and city market.

SIP/H.323 gateway with Asterisk PBX
Smékal, Lukáš ; Herman, Ivo (referee) ; Kovář, Petr (advisor)
This Bachelor’s thesis is engaged in problems of the internet telephony and its usage in today´s world, which offers many techniques how communicate among people. The internet telephony gives telephoning other format and shows new possibilities of IP protocol´s usage. The thesis is focused on the most used protocol corveying functions of VoIP technology, it is the standard H.323 and also the SIP protokol, which even if provides the same functions as H.323 is based on the different principle and because of its easy structure, it prepares good conditions for rise of new applications and services in internet telephony. In this thesis the Open Source private branch exchange Asterisk is also discussed. Asterisk, not only thanks to the usage of Voice over IP provides against the standard analogue private branch exchange many advantages and thanks to its modularity and expansibility also offers much more possibilities of configuration. The Session Initiation Protocol (SIP) is the basic protocol, with which Asterisk works. The standard H.323 is not implemented in the basic installation of Asterisk, therefore it is necessary to do its suitable installation and congiruation, in order to expand exchange´s functions for work with this standard and also to be able to realize translation between the protocol SIP and the standard H.323. The results, which I accomplished, are presented in the chapters „Dosažené výsledky“ and in the conclusion of the bachelor’s thesis.
