Chaotic Chen System for RGB Image Transmission by Parameter Switching

This paper aims for the secure transmission of RGB image using the Chen system simulated in Matlab-Simulink. The Chen system is implemented with master slave topology. The master end behaves as the chaotic system, whereas the slave system behaves as the stabilized Chen system implemented using the parameter switching methodology. The chaos is added to the image at the transmitter end, i.e. at the master end the chaotic image is transmitted through the system. At the receiver end, i.e. the slave end, which is a stabilized Chen system implemented using the parameter switching method, the chaos is removed from the received image, and hence retrieving the original information. The system helps in encryption of information before transmission, so as to secure the date from stealing of theft, the retrieving the original information back. Finally, the correlation factor value is compared between the original and the received image after removing the chaos, with the different set of parameters used.
