An Image Encryption Technique based on Chaotic S-Box and Arnold Transform

Abstract

In recent years, chaos has been extensively used in cryptographic systems. In this regard, one dimensional chaotic maps gained increased attention because of their intrinsic simplicity and ease in application. Many image encryption algorithms that are based on chaotic substitution boxes (S-boxes) have been studied in the last few years but some of them appear to be vulnerable to robustness. We, in this paper, propose an efficient scheme for image encryption that utilizes a composition of chaotic substitution based on tent map with the scrambling effect of the Arnold transform. The proposed construction algorithm for substitution box is, on one hand, straightforward and saves computational labour, while on the other, it provides highly efficient performance outcomes. The understudy scheme uses an S-box, that is based on 1-D chaotic tent map. We partially encrypt the image using this S-box and then apply certain number of iterations of the Arnold transform to attain the fully encrypted image. For decryption we apply the reverse process. The strength of the proposed method is determined through the most significant techniques used for the statistical analysis and it is proved that the anticipated algorithm shows coherent results.

FPGA-based Chaotic Cryptosystem by Using Voice Recognition as Access Key

“…In the last decade, a lot of researchers have introduced chaotic techniques that have been implemented in information encryption systems. For example: the authors in [12][13][14][15][16][17][18] proposed different methods to generate pseudorandom sequences that are verified by performing statistical tests of the Federal Information Processing Standards (SP 800-22) [19] of the National Institute of Standards and Technology (NIST), to evaluate their levels of randomness. In [20], a Chaotic Pseudorandom Binary Generator (CPRBG) was presented and synchronized to another CPRBG to perform image encryption.…”

To Study the Effect of the Generating Polynomial on the Quality of Nonlinear Components in Block Ciphers

“…Hussain et al presented -box algorithms using generalized Bakers map [8] and projective general linear group [9]. Algebraic, analytical, and chaotic approaches for -box are studied in [10][11][12][13].Özkaynak et al [14] applied fractionalorder chaotic Chen system, to develop -box. Tian and Lu [15] structured dynamic chaos-based -box in conjunction with DNA sequence operation.…”

“…Some other more efficient algorithms could be reviewed in [6,[16][17][18][19][20]. In addition to this, applications of -boxes in digital image encryption, steganography, and watermarking have become quite popular and influential in recent years [4,11,13,21].…”

A Novel S-Box Design Algorithm Based on a New Compound Chaotic System

“…As a result, the output bit sequence has strong resistance to linear and differential attacks. Several approaches such as the analytical approach [12], algebraic techniques [14], Boolean function [16], cubic polynomial mapping methods [17], and triangle groups [18] have been applied to S-Boxes construction.In recent years, chaotic systems have been widely applied in the design of S-Boxes because of their good cryptographic characteristics [19], such as random-like behavior [20], non-periodicity [21], and extreme sensitivity to initial conditions [22]. In [23], Lambic applied discrete chaotic map to design S-Box.…”
