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.
