Secure Gateway for Wireless IoT Protocols
Hošala, Martin ; Hujňák, Ondřej (oponent) ; Kořenek, Jan (vedoucí práce)
This work aimed to create a functional prototype of a secured gateway for wireless IoT protocols based on the BeeeOn IoT Gateway. To create the resulting solution, it was necessary to analyze existing IoT securing systems, propose their integration with the BeeeOn Gateway, and finally deploy the system. As the securing systems in this work, NEMEA modules developed within SIoT project were used. The resulting solution runs on Turris Omnia router and consists of the BeeeOn Gateway, five SIoT detection modules and other NEMEA modules necessary for detectors full functionality. Potential threats are being detected in the Z-Wave, BLE, and LoRaWAN networks. A user can interact with the system through a web interface of Coliot system, which is also a part of the resulting solution and serves to store and present detection results. The system functionality was verified experimentally and by a set of integration tests. The testing has revealed many deficiencies connected to used subsystems, and most of them were fixed. Resulting system is used within the SIoT project.

Decentralized E-Voting on Solana Blockchain
Hošala, Martin ; Očenášek, Pavel (oponent) ; Homoliak, Ivan (vedoucí práce)
This work was aimed at finding out the suitability of Solana blockchain for BBB-Voting system and creating a prototype of this system based on the provided solutions on Ethereum. The problem with Ethereum is its performace - a larger voting would take weeks. Solana promises much higher performace. To create the final solution, it was necessary to analyze Solana's system, BBB-Voting, design BBB-Voting for Solana, implement and test it. The final prototype is implemented in Rust using the Anchor framework. During the development, it was found that the algorithm which within the BBB-Voting protocol is used for vote validation is too computationally intensive and therefore due to the current limit on Solana, the system cannot be deployed on the mainnet. However, it is expected that this limit will be changed and the system can be deployed in the future. In that case, a rough estimate of the speedup over Etherem counterparts is around 3000 %. The cost of voting on Solana is also an order of magnitude lower. As part of the work, a front-end for voting was also developed - a single-page web application built using ReactJS.
