In this work, to overcome the flaws of standard chaotic maps we generated two new cascaded structures, 3D Cubic-Sine and 2D Cubic-Cat chaotic parametric maps, based on a new parameter-varied Cubic map that enhance the chaos complexity and therefore offering a high randomness's level of the chaotic sequences and a huge key space.To provide optimum security for image transmission, we introduce several methods with a new approaches in Stenography and encryption of quadrature amplitude modulation symbols (QAM)based on the new maps, all in a purpose of enhancement physical layer security. Some of the best results obtained are: the peak signal-to-noise ratio (PSNR) values of 96.2956 dB, 88.767 dB, 78.1094 dB respectively with the three methods, also the entropy of encrypted image reaching much closely the ideal value, being 8 approximate to 7.9999868, strong resistance against differential attack with Number of Pixels Change Rate (NPCR) of 99.63%, Unified Average Changing Intensity (UACI) of 33.54% and high speed ciphering based on 3D Cubic-Sine noise encryption time of 0.024s.The experimental results indicate that these new maps outperforms the most competitive recently proposed maps in multimedia cryptosystems. |
