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.

Application for secure data storage for mobile devices
Kocáb, Marek ; Martinásek, Zdeněk (referee) ; Mácha, Tomáš (advisor)
This bachelor’s thesis is focused on the creation of application for secure data storage for mobile devices. The paper theoretically describes operating system according to users popularity and programming languages. The following section explains AES encryption standard and its principle of data encryption and decryption. In the practical part is created a PINapplication programm. The application allows user to store sensitive data using chosen password. It is possible to save new data or erase current data. These data are encrypted by mentioned AES standard. The application is programmed in Java language with the version for mobile devices (J2ME).

Implementation of Encryption Algorithms in VHDL Language
Fruněk, Lukáš ; Fukač, Tomáš (referee) ; Kořenek, Jan (advisor)
The thesis deals with the design and implementation of the encryption algorithms DES and AES, operating in the CTR mode. The designed modules are implemented in the VHDL language and are mapped in the FPGA Intel Arria 10 SX 480. Algorithms are optimized for maximum throughput using loop unrolling and inner pipelining. The encryption module for DES reaches throughput of 26.2 Gbit/s with the circuit operating 410 MHz, and the module for AES reaches throughput of 34.6 Gbit/s with the circuit operating at 271 MHz. The reached throughput is in the order of thousand times faster than of the same encryption algorithms implemented in software for built-in microprocessors.
