Simulation of cryptographic algorithms using FPGA
Németh, František ; Mašek, Jan (referee) ; Smékal, David (advisor)
Bachelor thesis is dealing with a cipher standard AES and with a design of encryption and decryption components for AES in special modes of operation. Programming language is VHDL. In theoretical part of thesis is a further descriptions of AES and behaviour of block cipher operation modes. Furthermore the brief description of VHDL, FPGA and NetCOPE framework is a piece of theoretical part as well. The practical part contains designs which are made in developing environment Vivado from Xilinx. Programmed modes of operation are ECB, CBC, CTR and CFB. Simulation outputs and synthesis results are summerized in tables.

Design of hardware cipher module
Bayer, Tomáš ; Stančík, Peter (referee) ; Sobotka, Jiří (advisor)
This diploma’s thesis discourses the cryptographic systems and ciphers, whose function, usage and practical implementation are analysed. In the first chapter basic cryptographic terms, symmetric and asymetric cryptographic algorithms and are mentioned. Also usage and reliability are analysed. Following chapters mention substitution, transposition, block and stream ciphers, which are elementary for most cryptographic algorithms. There are also mentioned the modes, which the ciphers work in. In the fourth chapter are described the principles of some chosen cryptographic algorithms. The objective is to make clear the essence of the algorithms’ behavior. When describing some more difficult algorithms the block scheme is added. At the end of each algorithm’s description the example of practical usage is written. The chapter no. five discusses the hardware implementation. Hardware and software implementation is compared from the practical point of view. Several design instruments are described and different hardware design programming languages with their progress, advantages and disadvantages are mentioned. Chapter six discourses the hardware implementation design of chosen ciphers. Concretely the design of stream cipher with pseudo-random sequence generator is designed in VHDL and also in Matlab. As the second design was chosen the block cipher GOST, which was designed in VHDL too. Both designs were tested and verified and then the results were summarized.
