Hybrid, Secure and Highly Speed Method for Color Image Cryptography

A new method of color image cryptography will be produced, it will be shown the simplicity and easy use of this method, which can be used to encrypt-decrypt any image with any size without doing any changes in method operations. The proposed method will provide a high level of image protection by increasing the private key space to make the hacking process impossible. The proposed method will use two private keys to insure image protection, the first key will be a resized color image_key, the second key generated using chaotic logistic map model with a selected secrete parameters. The generated two 3D keys will be used to apply two rounds of XORing to encrypt-decrypt the color image. The proposed method will be implemented and the results will be analyzed. Several types of analysis (Quality, speed, correlation, speed, sensitivity, and simplicity) will be performed to prove the enhancements provided by the proposed method comparing with other existing methods of image cryptography
