Speech Encryption on FPGA Using a Chaotic Generator and S-Box Table


In this paper, we proposed a new technique for designing a dynamic S-box depended on the idea of DNA module and Chaotic system to increase its security. Lorenz chaotic generator is utilized as the chaos part of the proposed design. This design is Tested on the Field Programmable Gate Array (FPGA) for the use of offline speech encryption and decryption in real time. The experimental results are presented on the oscilloscope. The security of the system is also validated through tests on Matlab. © 2019 IEEE.
