The use of smart-cards in modern cryptography
Kočíř, Michal ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
This thesis discusses the general use of smart cards in MULTOS in cryptographic applications. At first is described two types of authentication - the authentication by the subject with focusing on authenticators and the authentication by the knowledge. Furthermore there is the description of the anonymous authentication and attribute authentization. This is followed by a description of smart cards with a focus on MULTOS cards. There is also performed analysis of programmable smart cards .NET, JavaCard and MULTOS. Practical part is focused on the implementation of an authentication scheme, which is being developed at FEEC. The communication of authentication protocol is between the MULTOS card and reader connected to a PC. The protocol is composed of cryptographic functions such as random number generation, hash function, modular exponentiation, modular multiplication and difference of large numbers. It was also implemented the measurement of specific applications.

Electronic geocaching
Průcha, Jan ; Strašil, Ivo (referee) ; Burda, Karel (advisor)
The master’s thesis is focusing on electronization of worldwide known game geocaching. It contains introduction to classic geocashing, analysis of current status and outline of possible solution. The design of electronization is based on smart card Gemalto. Very important part of the thesis is cryptographic security, therefore there is explanation of symetric and asymetric cryptography. The digital signature of transmitted message is realized by RSA algorithm, which is supported by the Gemalto smart card. Due to future expandability, it is appropriate to use general protocol. For this reason was chosen the ACP protocol which the supervisor of thesis adviced. In the following part, there is introduction to smart cards, their types and detailed description of Gemalto smart card. In the chapter 7 starts the solution of this issue and there are described the programmed apps.

Multiaplication smart cards
Meluzín, Ivo ; Malina, Lukáš (referee) ; Sobotka, Jiří (advisor)
The goal of the first part of the thesis is to describe the options of wide usage of chip cards in different segments of our life. Consequently it is necessary to mention hardware and software equipment of smart card, its communication with terminal and data security. In this thesis we focus on Java Card environment in which we will try to create two applications, one for electronic purse and the second for user identification. Basically, we need to mention multiapplicational rules of sharing data and objects. At the end of the thesis we are focusing on the possibility of mutual interference between the applications and on protection against attacks. Also future applications of this technology are described.

Design of security infrastructure for electronic archive
Doležel, Radek ; Lattenberg, Ivo (referee) ; Zeman, Václav (advisor)
This master's thesis deals with design of security infrastructure for electronic archive. In theoretical part is disscus about technical resources which are based on security services and protocols and methods which are used for protection. On basics of theoretical part is designed model of security infrastructure and it is built in laboratory. Model of security infrastructure is based on Open Source Software and as safety storages for private user authentication data are used cryptographic USB tokens. This master's thesis includes design and construction of real infrastructure of secured electronic archive. In each part of master's thesis is put main emphases on security and clear explanation from the beginning of desing of model of security infrastructure for electronic archive to finish of construction.

New physical attacks and security of smart-card
Hrubý, Jaroslav
Power analysis is a successful cryptonalytic technique which extracts secret inforamtion from smart-card by analysing the power consumed during the execution of their internal programs. These attacks are particularly dangerous in financial applications in which users their smart-cards into teller machines which are owned and operated by potentially dishonest entities.

Payment cards in practice and their analysis
Král, Michal ; Schlossberger, Otakar (advisor)
The subject of bachelor thesis is a payment card and its concepts in terms of practice. The payment cards are seen primarily from the current users, i.e. holders of payment cards. The thesis deals with the areas of their origin and development, description of basic characteristics and solves the current issues related to security, especially in the Czech Republic. Thesis is also focused on the practical analysis of payment cards in which the emphasis places on the bank charges associated with the use of payment cards.

The Usage of Smart Cards in the Area of Digital Signature
Jirovský, Tomáš ; Toman, Prokop (advisor) ; Obruča, Jan (referee)
This master thesis deals with the usage of smart cards in the area of digital signature. The descriptive part of this work outlines the basic principles of digital signature, smart cards typology and current most important application areas of smart cards. The first aim of the analytic part of this work is to evaluate actual situation on the smart cards market and to estimate future market trends. The second aim is to provide summary of new technological trends and areas, in which the usage of smart cards can be expected. These new technological trends and areas are described on the basis of survey, which was realized in the company OKsystem. Part of this work serves information about practical solution OKsmart and the analysis of its future development trends.
