Realization of attack on SHA-1 hash function
Dziura, Michal ; Hajný, Jan (oponent) ; Malý, Jan (vedoucí práce)
The bachelor thesis is concerned with hash functions, SHA-1 function and its implementation in Java. The thesis describes weaknesses of this function and implements the implementation of the selected attack leading to the revelation of source text or attack based on targeted falsifying hash. This work also describes characteristics of hash functions, constructions and their use. The last part deals with a description of the attack on the hash function SHA-1 with the complexity of the 2^69.

Cascade model of power lines for PLC
Dziura, Michal ; Mlýnek, Petr (oponent) ; Mišurec, Jiří (vedoucí práce)
The thesis is dealing with data transmission over the electric network. It describes PLC technology, its properties, and elements used in this type of network. The important part of this thesis is discussion over the mathematical model of distribution network with two-port cascades. Transmission functions created according to mathematical model were compared with each other. Thesis was concluded with observation of the impact of interconnected parts on transmission function of designed branched conductor. Final results were processed by Matlab and compared with each other.
