A color image encryption scheme reducing the correlations between R, G, B components

In this paper, a new color image encryption method based on confusion and diffusion processes has been introduced. A chaotic system based sub-block image swapping has been proposed in order to permutate the positions of the pixels as a confusion method. Moreover, the pixels in sub-block have been spirally shifted to increase the confusion level. Modulo and XOR operations which are based on a chaotic system have been suggested in order to...
