Hardware cryptographic modules for LAN security
Loutocký, Tomáš ; Lambertová, Petra (referee) ; Zeman, Václav (advisor)
The thesis deal with the problems of virtual private network (VPN). The first part of the thesis is focused on the description of the basic terms of computer security which are useful for better understanding the other parts. There is a description of VPN technology and its separation of VPN by various aspects in the second part of the thesis. The next chapter is dedicated to the description of realization of VPN by using IPSec. There is shown how to secure laboratory network by using of the products of the Safenet Company in the practical part of the thesis. There are also stated the modular techniques how to use products in the network in practical part. Some of the modular techniques describe security weaknesses of the products which are possible to exploit in the laboratory network and they also describe the ways how to protect them against misusage.

Wireless security facility
Gargulák, Lukáš ; Morský, Ondřej (referee) ; Zeman, Václav (advisor)
The content of this thesis is the design, construction and programming of wireless security device. This wireless security system consists of two units. Personal unit and sensor unit. This thesis compares two ISM bands 433 MHz and 868 MHz. The thesis presents a selection of parts for construction wireless security device. The work also deals with the structure of transmitted frames on the link layer. Marginally are discussed ways to reduce consuption AtmelAVR microcontrollers and also two ways of charging Li-Ion battery. It also outlined the firmware of both units. Its complete source code is included on the DVD.

Attacks on Cryptographic Modules
Daněček, Petr ; Zeman, Václav (advisor)
The conventional way of cryptanalysis is based on the cryptographic algorithms weak points examine. The attack model of conventional cryptanalysis covers mathematical description of the cryptographic algorithm used. This model is not with the relation to the physical model implementation and the real environment. Cryptographic algorithms currently used in the combination with strong cipher keys are almost unbreakable and the conventional cryptanalysis is ineffective. The new way of cryptanalysis employs the side channels. The model of cryptanalysis using side channels is enhanced with physical revelation of module performing the cryptographic operations. This dissertation thesis deals with cryptographic module description and studies influence of side channels to the security of this module.

Design of PLC network for remote data acquisition
Šebela, Miroslav ; Zeman, Václav (referee) ; Mišurec, Jiří (advisor)
In thesis is according assignment realized PLC (power line carrier communication) network design for remote data collection. To understand problematic of PLC is this technology described little bit in detail. In thesis are mentioned possibilities use broadband and especially narrowband power line carrier communication. Described is also general structure of PLC network for data collection - automatic meter reading. Finally is described realization of PLC network on chosen area included component supplier selection. In thesis is also mentioned problematic of PLC a communication channel included problems with noise and channel impairments. With selected PLC modems was realized and evaluated measurement of communication speed in different environments and with use of different interfaces. Furthermore was measured spectrum of communication signal from which was possible to define signal modulation. In last step were measured impairments in powerline.

Methods of measuring bit rates
Franc, Jan ; Mišurec, Jiří (referee) ; Zeman, Václav (advisor)
Study and basic benchmarking methodology description of network connections based on the IP was the objective of bachelor work. I resulted above all from RFC standards, by which are directed most of Internet protocols. Particular procedures for testing are explained in RFC 2544. On the basis of parameters analysis, I suggested conception and gave shape to web application which allows identify referenced basic transfer parameters of Internet connection (downstream, upstream, latency, scattering of connection speed). Application doesn’t require no add-ons and modules on user side. It is built on server programming language PHP with usage of relational MySQL database, in which are stored data. Client scripting language JavaScript is also used. Application offers measuring of mentioned parameters both to visitors and to registered users. Matter of course is user registration; work with history of carried out measuring, sending private messages between registered users. Above whole application exists administrator account.
