A Novel Image Encryption Algorithm Based On Chaotic Map

Abstract

Information security is the most important thing in this digital era. This work proposes a novel new image encryption algorithm based on chaotic map. Four different chaotic sequences are generated using logistic map. The generated sequences are used to perform confusion and diffusion operation. The position of the pixels are scrambled using confusion operation. Bit level value manipulation is performed using diffusion operation. The results shows that the encryption algorithm can resist statistical and differential attacks and hence gives a better security compared to other encryption methods.
