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.

SMS Encryption for Mobile Communication
Lisoněk, David ; Bouška, Petr (referee) ; Drahanský, Martin (advisor)
This thesis deals with encryption of short text message (SMS) in mobile communication. Introduction is dedicated to overview of the parts of GSM radiotelephone nets and SMS messages transfer . Next chapter is reserved for description of cryptographic methods especially symetric and asymetric encryptografic aproaches. A design of a SMS messages encryption and decryption techniques is in next. For SMS encryption and sign, there is used the asymetric cypher RSA. Encryption use OAEP padding schema. The public key is saved in certificate. The Symbian OS has been choosen as a suitable platform for programming of mobile devices.

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.
