An Altered Vigenère Circuit used in a Genetic Cross Again for Encryption of Medical Images

Abstract An innovative technique for encrypting colors and medical images will be provided in this paper. It is founded on the creation of many, arbitrary-sized substitution tables that are attached to current replacement and diffusion functions that produced from the chaotic maps employed. By applying an upgraded Vigenère circuit with the built S-Box, a genetic crossover suited to the encoding of color images with multiple chaotic vectors will be adopted. Finally, a genetic mutation is installed under the control of a chaotic table for the reproduction of the encrypted image capable of resisting any unexpected invasion. A massive amount of color images of various sizes and formats being simulated to verify the dependability of our cutting-edge technology.
