Chaos Blend DNA Coding for Image Encryption on FPGA

Looking at the demands of secure communication schemes, new platforms for information security have a significant role in the data protection. In this paper, image encryption on reconfigurable hardware FPGA has been proposed with the confluence of the chaotic map and DNA schemes. Confusion and diffusion were performed with both Chaotic and DNA approaches. The image encryption architecture with 128 × 128 grayscale image which was implemented on Cyclone II FPGA EP2C35F672C6 consumed 23,877 (72%) logic elements, 131,072 (27%) internal M4KRAM memory units with a total thermal power dissipation of 273.55 mW for a test image. NPCR, UACI, Correlation, Uniform distribution and entropy analyses revealed the strength of the proposed scheme which requires a specific bitstream and hardware to retrieve and decrypt the hidden secret image on FPGA.
