Abstract

In this paper, we present a hardware implementation of an enhanced version of the AES (Advanced Encryption Standard) algorithm, and evaluate its performance. In the proposed design, we replaced the original static S-boxes with a robust dynamic S-box generator mechanism. The principle consists of using the secret key to generate new dynamic S-boxes by applying a bitwise XOR operation with all 256 bytes of the AES standardized S-box. Then, the architecture is implemented on a Xilinx XC7Z020 PYNQ-Z2 FPGA platform to accelerate the calculations, and its robustness is evaluated using many security tests. The experimental results prove the satisfaction of our design for several cryptographic properties, such as nonlinearity, bijectivity, and strict avalanche criterion that confirm its resistance against the main cryptanalysis attacks.
