Security and Performance Testbed for Simulation of Proof-of-Stake Protocols
Borčík, Filip ; Veselý, Vladimír (referee) ; Homoliak, Ivan (advisor)
This work deals with performance and security testing of blockchain protocols based on the Proof-of-Stake (PoS) consensus model. It describes properties, problems, but also the use of blockchain systems. On theoretical levels, this thesis compares the properties and resistance to various attacks of numerous PoS protocols, specifically Algorand, Casper, Gasper, Snow White, Stellar and Decred. Additionally, this work implements a protocol simulator of Algorand, Casper FFG and Gasper. The simulator is built on top of the Bitcoin Simulator simulation tool, which is based on the NS-3 discrete network event simulator. Then, it compares the properties of the implemented protocols using discrete simulation.

Content Document Classification
Borčík, Filip ; Kačic, Matej (referee) ; Třeštíková, Lenka (advisor)
This work deals with document classification based on standard family ISO/IEC 27000. Points to a need, but also issues of classification in corporate environment. The work also implements system for MS office documents classification based on content analysis using defined rules. This system is introduced into DocTag application developed by AEC company.
