A Secure Image Encryption Algorithm Based on the Rubik’s Cube Principle
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
uses relatively small key spaces and thus offers 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 and resist to exhaustive attack, statistical attack and differential attack.

ABSTRACT: Inspired by the natural ripple-like phenomenon that distorts a reflection on a water surface, this paper introduces a new symmetric image cipher using wave perturbations to shuffle images in an n dimensional (n D) space. Its strong diffusion and confusion properties are ensured by pseudo-random wavefronts and additional salts and peppers bits. Extensive simulations and comparisons demonstrate that the proposed image cipher outperforms several existing bit-level scrambling methods with respect to the encryption quality and computation complexity.Signal Processing. 01/2014; 102:122–131.

ABSTRACT: A recently proposed secure image encryption scheme has drawn attention to the limited security offered by chaos-based image encryption schemes (mainly due to their relatively small key space) proposing a highly robust approach, based on Rubik's cube principle. This paper aims to study a newly designed image cryptosystem that uses the Rubik's cube principle in conjunction with a digital chaotic cipher. Thus, the original image is shuffled on Rubik's cube principle (due to its proven confusion properties), and then XOR operator is applied to rows and columns of the scrambled image using a chaos-based cipher (due to its proven diffusion properties). Finally, the experimental results and security analysis show that the newly proposed image encryption scheme not only can achieve good encryption and perfect hiding ability but also can resist any cryptanalytic attacks (e.g., exhaustive attack, differential attack, statistical attack, etc.).Mathematical Problems in Engineering 03/2013; 2013:1-10. · 1.38 Impact Factor

ABSTRACT: Images excessively contribute to communication in this era of multimedia. When a user transfers images over an unsecured communication network, then the absolute protection is a challenging issue to conserve the confidentiality of images. Encryption is a method of retaining the secrecy of images. This paper provides the succinct introduction to the cryptography, moreover, includes a concise description of various elemental securities' criteria of the image encryption algorithms. This work presents the survey of diverse image encryption techniques and comparison of discrete image encoding approaches, at last discloses a conclusion and suggests future works.
