Design and implementation of countermeasures against side-channel attacks on an FPGA platform
Kuřina, Petr ; Jedlička, Petr (referee) ; Dobiáš, Patrik (advisor)
Currently, significant progress is being made in the field of digital systems and cryptography, requiring adequate security against various forms of attacks. Special attention is paid to development on the FPGA (Field-Programmable Gate Array) platform, which provides flexibility and performance for implementing diverse applications, including cryptographic algorithms. This semester thesis focuses on the systematic analysis of possible leaks of sensitive information from the implementation of a cryptographic scheme on the FPGA platform. The FPGA platform is presented in the work, including HDL (Hardware Description Language) programming languages such as Verilog or VHDL. It then presents a general overview of side channels and their types, countermeasures, and a~detailed description of security techniques. The next chapter is the AES cryptographic scheme and a description of its operations. There is a chapter devoted to a comparison of current articles on the issue. The following is a description of a professional workplace, such as an oscilloscope or a Sakura-X (Sasebo-GIII) hardware board. In the final part, the measurement results are presented without any measures, only the AES algorithm is implemented, and then in the next part there is a countermeasure proposal, which is implemented and measured. The results are described and subsequently displayed in graphic form.
