OFDM Transmission for encrypted Images based on 3D Chaotic Map and S-Box through Fading Channel

It is important to prevent unauthorized access to data whether it is being transferred over a wireless network or stored on a personal computer. This paper proposed a 3D chaotic map and S-Box has been cascaded to get a high efficiency as complex algorithms or multi-iteration schemes. In this study, various encryption techniques, including cipher algorithms and substitution box, are combined with the OFDM system to establish a secure image transmission over a Rayleigh fading channel. Security analysis is performed to evaluate the quality and security of the encryption process. For image transmission evaluation, the PSNR and BER are utilized. According to the statistical results, the proposed image encryption scheme is secure and efficient.
