Verification of the statistical reliability of simulation results in OPNET Modeler environment
Fördős, András ; Vajsar, Pavel (referee) ; Hošek, Jiří (advisor)
Project is focused to verify the credibility of the results of statistical simulation in the surround of OPNET Modeler. At the beginning of the project is a short introduction to the problematic of OPNET Modeler. It describes the basic concepts of mathematical statistics, data types and some basic statistical charakteristics. In the project was created model of LAN network, were set up three different types of runs and several monitored statistics. In this project are listed setting of the model, startup parameters of some runtime simulations, prefered variety of statistics and the possibility to display final results of statistics. Description of options displaying final results of statistics is supplemented by model characteristics. Created model was further extended and modified. Have been added network services, has changed the number of nodes and the duration of the simulation. Results of analysis of the original scenario are compared to the results of a modified scenario, which are scheduled. At the end of this project are obtained result, recommended way and form of displaying basic statistics and advice on the number of simulation runs needed to obtain reliable results.

Cryptanalysis of modern cryptographic devices
Fördős, András ; Člupek, Vlastimil (referee) ; Martinásek, Zdeněk (advisor)
The thesis focuses on power analysis of modern cryptographic modules. The first part contains a brief introduction to the topic of the power side channel and basic methods of analyzes. The text describes the process of comparison of modules and a short description of devices found. In the practical part two modules has been selected for the implementation of the encryption algorithm AES-128. The first module was the chip card Gemalto .NET v2 and the second one was the Raspberry Pi. A workplace has been created for these modules which allowed to measure the power consumption of the algorithm AES. Differential Power Analysis has been made using the captured results. In its conclusion the work presents the results in tables and samples of source codes. Graphs were made from the results captured on the Raspberry Pi and from the results of the Differential Power Analysis.
