Low Detail Image Encryption Algorithm Based on Diffusion and Confusion Using Henon and Baker Chaotic Map

Abstract

This paper presents a solution for the security of low detail images in real-time applications over open or unsecured networks. The diffusion and confusion operations are both performed based on Henon and Baker chaotic map. The XOR and permutation operations are used to obtain diffusion and confusion in the algorithm. In the proposed technique, the high detail image is used as a key. The computer simulation results and security analysis are given to ensure the validity and strength of the proposed technique. In the security analysis, we have analyzed key space analysis, cropping attack analysis, noise attack analysis, and differential attack analysis. Some statistical analyses like entropy, histogram, and correlation coefficients are also given to check the strength of the presented technique.
