A Proposed Permutation Scheme based on 3-D Chaotic System for Encrypting the Colored Images

Osama M. Abu Zaid

In this paper, a proposed permutation scheme based on three dimension chaotic map system will be presented. Chen's chaotic system is 3-D chaotic map system, which will be used to obtain the proposed permutation scheme. A proposed permutation scheme will be designated as PPS3DCS. It will be applied on two different color's frequencies colored-images. A proposed scheme (PPS3DCS), which Contains permutation procedure based on Chen's chaotic system is used to shuffle the positions of pixels of the colored plain-image. PPS3DCS will be applied on all color's channels of the image; Red, Green, and Blue. The expectant results of several experiments, statistical analysis, key sensitivity tests, and information entropy analysis will show that the proposed permutation scheme (PPS3DCS) is a good encryption scheme to provides an efficient and secure way for confusing or encrypting the colored images.

Keywords: Chaotic map; permutation; Image encryption; 3-D Chaotic map system.
