Security and Performance Testbed for Simulation of Proof-of-Stake Protocols
Borčík, Filip ; Veselý, Vladimír (oponent) ; Homoliak, Ivan (vedoucí práce)
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.

Klasifikace dokumentů pomocí analýzy obsahu
Borčík, Filip ; Kačic, Matej (oponent) ; Třeštíková, Lenka (vedoucí práce)
Táto práca sa zaoberá klasifikáciou dokumentov podľa rodiny štandardov ISO/IEC 27000. Poukazuje na potrebu, ale aj problémy klasifikovania v korporátnom prostredí. Práca taktiež implementuje systém pre klasifikáciu dokumentov prostredia MS Office založenej na analýze obsahu pomocou definovaných pravidiel. Tento systém je zavedený do aplikácie DocTag vyvíjanej spoločnosťou AEC.
