Rubik's Cube and Image Encryption

Internet security is of great concern nowadays, especially after the recent headlines describing possible illegal activities by media sources and governments. To combat this intrusion on privacy, researchers are hard at work devising new encryption methods that provide the security users expect during online communication.

The "Rubik's Cube principle" forms the basis for a new encryption method for digital images described in a 2012 paper from researchers with Laval University in Canada.

This method repositions the pixels in a image by scrambling and rotating the pixels in a way similar to how one scrambles the Rubik's Cube, i.e., by rotating the cube to a new configuration.

The researchers discovered that this method achieves good encryption with perfect hiding ability and can defend well against a variety of cyber-attacks.

Title: A Secure Image Encryption Algorithm Based on Rubik's Cube Principle

Authors: Khaled Loukhaoukha, Jean-Yves Chouinard, Abdellah Berdai
Dept. of Electrical and Computer Engineering, Laval University, QC, Canada

Abstract

In the past few years, several encryption algorithms based on chaotic systems have been proposed as means to protect digital images against cryptographic attacks. These encryption algorithms typically use relatively small key spaces and thus offer limited security, especially if they are one-dimensional. In this paper, we proposed a novel image encryption algorithm based on Rubik's cube principle. The original image is scrambled using the principle of Rubik's cube. Then, XOR operator is applied to rows and columns of the scrambled image using two secret keys. Finally, the experimental results and security analysis show that the proposed image encryption scheme not only can achieve good encryption and perfect hiding ability but also can resist exhaustive attack, statistical attack, and differential attack.

Merci +Pierre Lemay mais je dois recevoir mes deux tablettes mardi avant la fin de journée, selon mon avis de livraison de UPS. Très hâte.
