Implementation of Color Image Encryption in Gray Level by Using Pixel Shuffling and Single Chaotic System

Main aim of this project is Color image encryption in gray level by using Pixel shuffling and by single chaotic system. By the adoption of pixel shuffling can eliminate the image outlines, and the chaotic system is adopted to disrupt the distributional characteristics of gray level, and the resulting increases of key space. Various statistical methods, such as correlation coefficient, NPCR (Number of Pixels Change Rate), UACI (Unified Average Changing Intensity), and entropy, the application of this method to communication encryption and decryption gives a high level of security.
