Chaotic-image-encryption-algorithm

Background

Based on the nonlinear characteristic of chaos, a lot of encryption methods are designed by using chaotic systems.

Introduction

In this paper, we introduce a new Sine-Henon map (ICSM), which is a cascade of Sine map and Henon map. Combining the two-dimensional ICSM and CMT, a novel image encryption algorithm is also further elaborated.
