Chapter 4Hybrid Rubik’s Cube Algorithm for Wireless Communications
4.1 Introduction
In this chapter, a hybrid encryption framework based on the Rubik’s cube is suggested as a means to attain simultaneous encryption of a group of images. The suggested hybrid encryption framework begins with CFB operation mode of chaotic Baker map permutation or AES or RC6 technique as a first step for encrypting the multiple images, separately. Then, the resulting encrypted images are further encrypted in a second stage with Rubik’s cube technique. Chaotic, RC6, or AES encrypted images are utilized as the faces of the Rubik’s cube. From the concepts of image encryption, the RC6 or AES technique introduces a degree of diffusion, whilst the chaotic Baker map ...
