Security Analysis of Mifare Classic Smart Cards
Bobčík, Martin ; Hellebrandt, Lukáš (referee) ; Hujňák, Ondřej (advisor)
Goal of this bachelor thesis is a security study of MIFARE Classic contactless smart cards and risk analysis of their usage. There are described individual vunerabilities in the design and CRYPTO1 cipher of such cards. In this thesis is also experimented with Chameleon Mini device, which is used to perform two attacks and one cryptoanalysis of the cards. Namely, card emulation, relay attack, and analysis of insufficient randomness of cards' pseudorandom number generator. From those, only card emulation was fully successful.

MIFARE Classic Emulation on NFC-A Tag Peripheral
Lužný, Jakub ; Peringer, Petr (referee) ; Hujňák, Ondřej (advisor)
Cílem této práce bylo implementovat emulaci tagu MIFARE Classic na NFC-A periferii vestavěné v mikrokontroléru. K implementaci řešení byl použit mikrokontrolér nRF52832 vyráběný firmou Nordic Semiconductor. Byla implementována základní sada příkazů MIFARE Classic (autentizace, čtení, zápis). Implementace byla otestována s několika čtečkami, za pomoci různých aplikací. Výsledné řešení bylo porovnáno s existujícími, jako je Proxmark a Chameleon Mini.

Analysis of contactless payments
Švantnerová, Romana ; Schlossberger, Otakar (advisor) ; Hoffman, Andrej (referee)
The aim of this thesis is to provide a comprehensive view on the issue of contactless payments in various forms, as well as capture the actual situation in the field of contactless payments. The first chapter is devoted to the emergence and development of payment cards as a forerunner of contactless cards. The second chapter characterizes contactless cards as a new payment product. Additionally it also includes a description of the technology, which is used for this kind of cards. Chapter also deals with the arrival of contactless cards to Czech Republic and Slovakia. The topic of third chapter is Near Field Communication, special technology, which is used for contactless payments and also for the other forms of contactless payments, such as mobile payments. The fourth chapter talks about mobile services that are actually used for mobile payments. These services are not available in our region yet, but we expect their further expansion into European countries in the future. Finally, the last chapter includes an analysis of data, where we used statistical data of contactless payments in Slovakia and Czech Republic. The aim was to outline the development of contactless payments in individual quarters in both countries separately and to compare the data of contactless cards and payments in these countries.
