Side channel attacks on chip cards
Matějka, Jiří ; Morský, Ondřej (referee) ; Martinásek, Zdeněk (advisor)
This master thesis deals about the issues of chip cards’ side channels. Side channels are new method in cryptanalysis. Unlike classical cryptanalysis, which looks for weaknesses of mathematical structure of algorithms, side channel’s analysis use weaknesses of physical implementation of these algorithms. First part describes chip cards, their usage a security. There is mentioned the issue of cryptographic algorithms and their implementation on smart cards. There are described well-known side channels and examples of their abuse. Practical part of this thesis is focused on a proposal of a laboratory task, which demonstrates power-based side channel attack on smart card. There is designed laboratory workplace for this task, software for measurement and analysis is implemented in development tool LabVIEW. In the last part is this attack realized, the target of this attack is a standard SIM card.

SIM Card Reader
Buchta, Petr ; Strnadel, Josef (referee) ; Vašíček, Zdeněk (advisor)
This thesis focuses on implementation of a SIM card reader. Methods of data transmission are described here together with principles of file organization and data storage. As another topic, implemented functions in a SIM card used for manipulation with its contents, are described here. The FITkit platform and its utilities are used for the implementation of a SIM card reader.
