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.

Secure access to web interface
Kazik, Milan ; Hajný, Jan (referee) ; Rášo, Ondřej (advisor)
This document contains basic principles and processes regarding secure access to web information system. It consists of theoretic and applied part. These are mainly written together in thesis’s chapters. Theoretic informations were tested on simple web application created in PHP computer language on Apache web server using MySQL database. In the beginning, there is an analysis of used programming environment, especially it’s advantages and disadvantages. The main part of this document is simple characterization of many security problems which can be found on many websites all around the world. In the first place it’s a handling problem of inputs and outputs in the web applications. Password disputableness is solving separatelly. Theory of a problem is analysed first of all. Then a couple of solving methods are suggested and the one which is practically realized is described in detail. There is a notification system created which is used to inform user about errors appeared in web application. In the last section there is a client and server certificates described. This document contains fully characterization of used scripts and connection between them. They are supplemented with many pictures and screenshots which are used to better understanding the disputableness of web security.

Digital signature
Vaverka, Aleš ; Lambertová, Petra (referee) ; Zeman, Václav (advisor)
Digital signature, the subject of this semester paper, is nowadays very up-to-date. The still rising capabilities of the internet and the vision of lowering the amounts of paper documentation made it necessary to develop a way of signing documents which are transferred through the internet. This is supposed to be equally safe and unassailable as the handwritten signature. This method is called the digital signature. The paper focuses on the explanation of the essential terms connected to digital signature, such as certificate, certification authority, authentication, but in particular on the elementary cryption algorithms, further on applications that make use of digital signature, e.g. post services and electronic banking. In the final chapter, the positive and negative aspects of the electronic signature are discussed.
