Securing narrowband wireless communication in licensed band
Kolaja, David ; Brychta, Josef (referee) ; Fujdiak, Radek (advisor)
Contemporary demand for mobile devices and development of devices in the Internet of Things is constantly increasing. This reality also raises concerns about security and privacy of ongoing communication. This is no exception for expanding scale of Low Powered Wide Area Network (LPWAN) devices which communicate over Narrowband IoT and the customer of such devices who has to rely on security of provider’s network to secure customer’s data. This security is effective only in operator’s network while there is no end-to-end encryption enabled. Therefore, this thesis deals with the analysis of NB-IoT communication and its possible end-to-end security proposal, which also provides elements of post-quantum algorithms. Last but not least, this thesis deals with application of this proposal on constrained device and evaluation of its effectivness of time, energy and memory demands.

Universal communication unit
Ružička, Michal ; Mlýnek, Petr (referee) ; Sláčik, Ján (advisor)
This bachelor thesis is going to deal with communication over the power network. Aim of this project is to clarify this issue and consequently to use the acquired knowledge for desingning own communication unit. The basic parameters of power network which influence this type of communication are being described in this thesis. The concept of universal communication unit is created. Pheripheral solutions are chosen for this concept and the given device will be made of them. The custom communication unit is created on this basis. The funkcionality of this unit is tested in the work.

Possibilities of data communication over LV power lines
Pataj, Jiří ; Zeman, Václav (referee) ; Mišurec, Jiří (advisor)
This thesis deals with possibilities of data communication on low voltage power lines, so-called PLC. This technology allows data transfer on power lines. According frequency band the PLC can be subdivide into narrowband or broadband class.The first part of the thesis deals with theoretical knowledge of data communication on power lines and describes technical solutions. Second part of the thesis deals with narrowband PLC, which is accessible for commercial usage and it is suitable for remote data collection. The last part of the thesis focuses on measuring with device PowerLineDHP-301 made by D-link. The results are real bitrates depending on distance and quality of specific connection.

Securing Narrowband Wireless Communication In Licensed Band
Kolaja, David
With everlasting growth of development of devices in the Internet of Things, there is also a difficulty to keep up with the requirements of security-related topics on such devices. This is no exception for expanding the scale of Low Powered Wide Area Network (LPWAN) devices which communicate over Narrowband IoT. Such devices have constrained computing power. Thus developers of these devices are limited to use as much as possible for the implementation of functions, not having enough space for securing its communication. This article focuses on how to possibly secure these communications.
