Most block-cipher image encryption schemes based on chaos theory have independent modules for confusion and diffusion processes. None of the current schemes use chaos theory in the diffusion modules - thus not utilizing the capabilities of chaos to the fullest extent. We can do better: we integrate these mechanisms into a single step, thus making the encryption process efficient. This paper presents three novelties: (a) we extend 2D images to 3D by using grayscale image intensities in 8-bit… CONTINUE READING
