A Novel Chaotic Permutation-Substitution Image Encryption Scheme Based on Logistic Map and Random Substitution

Abstract

Privacy is a serious concern related to sharing videos or images among people over the Internet. As a method to preserve images' privacy, chaos-based image encryption algorithms have been used widely to fulfil such a requirement. However, these algorithms suffer from a low key-space, significant computational overhead, and a lag in resistance against differential attacks. This paper presents a novel chaotic-based image encryption method based on permutation and substitution using a single Substitution Box (S-Box) to address issues in contemporary image encryption algorithms. The new proposed encryption technique's efficiency is validated through extensive experiments as compared to the state-of-the-art encryption algorithms using different measures and benchmarks. Precisely, the collected results demonstrate that the proposed technique is more resilient against well-known statistical attacks and performs well under plaintext attacks. Indeed, the proposed method exhibits very high sensitivity concerning the plaintext attack. A minor change in the encryption key or the plain text would result in a completely different encrypted image.

“…Then, the initial key is set to K ={x 0 , y 0 , a 0 , b 0 }, and the set initial key is updated by using Eq (9).…”

“…When they are applied to image encryption, it takes a lot of time resulting in low encryption efficiency [4]. Therefore, researchers have proposed many different image encryption techniques, which contain image filtering [3], DNA coding [5], frequency domain transform [6], elliptic curves [7], compressive sensing [8], S-Box [9], fractional Fourier transform [10], neural networks [11], chaotic systems [12]- [14], etc. However, among these technologies, because of the special nature of chaotic systems, cryptography based on chaotic systems has become one of the most popular cryptographic schemes.…”

“…Mansouri et al proposed an image encryption algorithm based on a one-dimensional chaotic system, where they added chaotic sequences to the original image during the diffusion process to improve the security of the algorithm [15]. J. Arif et al proposed an image encryption algorithm based on Logistic map and S-Box [9]. They used S-Box to perform pixel substitution in the pixel diffusion stage to enhance the security of the algorithm, but this algorithm can only be used for grayscale images.…”

A Lightweight Image Encryption Algorithm Based on Chaotic Map and Random Substitution

“…Most of the prior works on image encryption [ 5 , 6 , 7 , 8 ] do not consider encryption speed in their design. In this work, we propose a lightweight image encryption algorithm considering the encryption speed.…”
