Software support for cryptography education
Stančík, Peter ; Vyoral, Josef (referee) ; Burda, Karel (advisor)
The main aim of this thesis was to study, choose and decribe techniques eligible for cryptography education. A pedagogically appropriate presentation for the selected techniques' principles was to be chosen. Another goal was to create an integrated modular web interface containing a calculator focused on cryptographic operations. The eligibility of techniques was assessed accordingly to the computing processes implied by these techniques and also accordingly to the ability of being presented in an illustrative way. A program simplifying calculations used in symetric and asymetric cryptography was designed and implemented. It disposes of a web interface and one of its parts is focused on steganographic techniques. On the other hand, any pedagogically appropriate presentation interconnecting this program with theoretical findings from this field was not found.

Preparation of web pages for handicapped users
Krupa, Martin ; Vyoral, Josef (referee) ; Cvrk, Lubomír (advisor)
My bachelors thesis says about creating of accesible web pages, eplains why are accessible web pages neccessary, elucidate who are handicaped users, shows with whitch problems they can meet on internet, witch accestories they use and why is important to devote to this problem in practice. It also explains methods used for testing of accessiblity. Not every user is equal, everyone has his owns needs and so unique requirements, that is not able to overleap or elude. Practically they are visual and audio dissabled, users with deteriorated motile of upper limbs and users with disorders of learning and concentracion. This users have their own auxiliary technologies, for example audio responses, braille’s lines etc., that mediate informations from web pages to them. If we want these widgets to work, it’s neccessary, that these pages would be created with some rules and policies of accessible web. These web pages are more also ussefull for standard users.

Quality of services in IP Telephony in Wirelass Networks
Slavíček, Tomáš ; Kyselák, Martin (referee) ; Vyoral, Josef (advisor)
The thesis deals with the principles of assurance quality of services in IP networks. The first part of the thesis describes specifications which are required by current applications for data network, and also illustrates the methods suitable for solving those requirements. The most attention is given to multimedia service VoIP whose development has not been finished from far. That theoretical knowledge implies in the second part of the thesis which analyzes the implementation of assurance QoS for the service VoIP within the standard 802.11, or more precisely, for wireless networks in general. The simulation of wireless networks within the program Opnet Modeler and the attest of the ability to assure QoS within both wireless networks and their limitations with an unswitched network are described in the next step. The current possibilities how to build up WLAN with the bearing QoS are sized up in conclusion.

The Differences Between PHP and ASP.NET in Dynamic Web Development
Jánoš, Radan ; Vyoral, Josef (referee) ; Kovář, Petr (advisor)
This bachelor thesis analyses the possibilities of dynamic web content development by the help of technologies PHP and ASP.NET, attempting to compare both of them and establishes basic differences. All work is divided into the four main chapters. First, introductory part, treat of dynamic web content development, used technologies and initiatress reader to the given problems. The second chapter is already about analysing and comparing the two technologies mentioned above. This part begins by the basic introduction and history of technologies, follows practical part „ installation, setting, configuration", where is reader familiarized with needed development tools for starting each of technology. Further treat of the way of writing server code including syntax of languages, in which is PHP compared with language C# and describes the object orientation of languages. Chapter includes the samples of data access by both of the technologies, whether it uses functions or objects, special libraries etc. Summarises the support of platforms for mull over technologies and describes development environments that can be used to realize applications by the help of these technologies. Third chapter is engaged in design and practical realization of simple editorial system web application in both above described technologies. The editorial system is using appropriate database systems and includes basic content management interface, which is administred and managed through the web interface. Last chapter contains final estimation and summarization of ascertained conclusions, recapitulate downright findings and tries to answer the question, in which cases give priority to ASP.NET before PHP and on the contrary.

Design of the laboratory task for attack on fingerprint authentication
Spurný, Jiří ; Vyoral, Josef (referee) ; Burda, Karel (advisor)
This thesis deal with personal fingerprint authentication and contains basic types of fingerprint readers included their principles of working. In this thesis are collected published attempts to this type of biometric authentication and in detail described way, how these attempts were realized . Realization of lab measurement is mentioned in practical part of thesis, is designed based on collected and evaluated information. Tendency for realization was to use materials and procedures which are available on market as well as computer technology. So no special equipment is needed for realization. Practical part describes in detail procedures for papillary lines capturing and their electronic processing. Described is also way to break through optical finger print sensor. For confirmation of procedure was made 12 artificial finger casts from Lukopren material. There casts were used to attempt on optical sensor Microsoft Fingerprint Reader with 100% success. Based on realized tests to produce artificial casts was proposed procedure for realization of laboratory measurement. This procedure is described in main part of this thesis. Proposed procedure has been confirmed in 90 minutes time limit, based on requirement to achieve time limit of school training session.

Architecture of channels in UMTS networks
Souček, David ; Vyoral, Josef (referee) ; Novotný, Vít (advisor)
Mobile networks and their services are one of the most importantly developing domains of telecommunication these days. The mobility of subscribers and services is the funda-mental need for dynamic development of not only the economics, but also of other fields of human performance. The charge for the mobility and integration of various kinds of services in mobile networks is an extensively complicated architecture and a protocol equipment. The important aspect of mobile networks is the efektivity of utilization of radio sources, which are scarce and form so called narrow neck of the communication chain between the mobile terminal and the network terminal. That is the reason why the perfection of mobile technologies is closely related to the improvement of efficiency of the usage of radio sources, which is reflexed in the UMTS network by an extensively complicated layer architecture of communication channels, that is formed by three layers as distinct from the GSM/GPRS network, where the architecture of channels was in two layers.

Position monitoring with the help of GPS/GSM modem
Zavadil, Miloš ; Vyoral, Josef (referee) ; Šilhavý, Pavel (advisor)
The first chapter of bachelor thesis is focused on theoretical explanation of the most important terms in Global Positioning System describing basic principles and position monitoring possibilities. The structure of the whole GPS system and its position setting accuracy is described further. The NMEA protocol used for transferring GPS information is shortly mentioned too. The second chapter deals with Open AT platform used for application development. It is a product of Wavecom company. The third thematic unit has already practical character. It shows the results of locating GenLoc25 modem by AT commands and decoding NMEA frame. Three variants of applications developed in Microsoft Visual C++ are described in the last chapter. All of them are used for position monitoring with GPS/GSM modem. The first program has the same functionality as the modem locating by AT commands. It is only for visualization of GPS information in Terminal window. The second application we can consider as the most important in this thesis. It contains all the items from the assignment. Actual data position is automatically sent to FTP server by GPRS transmission. The data are stored on this server. Received data are visualized in web browser by PHP script which is stored on server too. Final application is derived from the second one. The algorithm assumes that data are not sent to server regularly but transmission depends on human factor.
