A New Color Image Encryption Scheme Based on Chaos
Huai Xun Zhao, Peng Cheng, Jun Hao Han · Applied Mechanics and Materials · 2014
This letter presents a new color image encryption scheme based on the coupled chaos maps. First, the algorithm uses the coupled logistic map to generate random strong key stream, and then designed a kind of initial simple diffusion-joint scrambling-combined diffusion method from the point of the relationships of components R, G, B. The simulation results indicate that this algorithm has stronger security compared with the independent encryption of each color component.
