Hardware for lightweight cryptographic implementation
Jedlička, Jakub ; Cíbik, Peter (referee) ; Smékal, David (advisor)
This bachelor thesis deals with the topic of lightweight cryptography and the implementation of a selected cipher on a field programmable gate array (FPGA). Thesis first deals with the theory, where hardware elements, general cryptography and lightweight cryptography are described with focus on the LBlock and PRESENT ciphers. It then describes the selection of a cipher type and then the selection of a particular lightweight cryptography cipher. Next the LBlock cipher is selected, implemented, and tested as a custom intellectual property (IP) block using a hardware descriptive language for very fast integrated circuits (VHDL). This block is used in the block design to implement the encryptor on the ZYBO-Z7 development board. The input and output data handling is implemented on the Zynq-7000 processing system chip, which passes the data to the programmable logic. Finally this communication and implementation is described where the operational modes used for the LBlock cipher are cipher feedback mode and output feedback mode. For these operational modes, measurements are made to determine the encryption speed of the data stored on the microSD card and the pitfalls resulting from this encryption are described.

FITkit - PC Crypted Communication
Kouřil, Miroslav ; Strnadel, Josef (referee) ; Růžička, Richard (advisor)
This thesis deals with the issue of concealing confidential data being transmitted in between two systems. The coding standard AES as a block symmetric cipher has been selected. In practise, the connection between the FITkit platform and a PC was set via serial communication. The FITkit is programmed in language C and the PC in language C++ . There has been designed a simple protocol for setting up the connection and for the information exchange about encoding. Due to the difficulties with serial communication on the kit side there have been created two applications. The first application reads encoded kit data and translates them with the assistance of preset values. The second one communicates with the kit emulator on the other computer and works at full range, what means - establishing the connection, generating keys modes and number of encoding rounds, safe key exchange and the possibility of data reading and writing to the kit.
