A novel encryption using one dimensional chaotic maps

Abstract

This paper introduces a simple and efficient chaotic system using one-dimensional (1D) chaotic map. For high security purpose this paper proposing a new encryption algorithm and it consists of uniform density function. This algorithm has more security to different type of images such as gray scale images, color images. The proposed algorithm transform images into different noise like encrypted images with excellent confusion and diffusion properties. Using a security keys this algorithm provides different encrypted image. In this paper we explain about scrambling system using hyper chaotic system it provides RGB color image which splits the three components and then by using hyper chaotic sequence generation we generate the scramble the original image. Using a same set of security keys, novel image encryption algorithm is able to generate a completely different encrypted image each time when it is applied to the same original image, and it has high sensitivity and good ability of resisting statistic attack.
