A High-Security Image Utilizing Triple Generators for the Rabinovitch System

Abstract

Chaotic encryption offers a higher level of security than traditional ciphers. This research provides an encryption system using chaotic sequences to encrypt digital images using three hyperchaotic methods. The first system generates a random integer number sequence between (0 -255), while the second and third hyper-chaotic generators use a chaotic random selector from the random number generated from the first hyperchaotic generator and the image pixels. The third system is used to chaotic select the pixel from the image. Then the pixel value is changed using the XOR operation to encrypt the pixels. The number of keys depends on 33 dimensions (each hyper-chaos has 11 dimensions, four initial values, five parameters, and two big and mod numbers), and all available keys at less than 2 1644 . This number represents a massive key space.
