Color Image Encryption Through Chaos and KAA Map

The unprecedented growth in production and exchange of multimedia over unsecured channels is overwhelming mathematicians, scientists engineers to realize secure efficient cryptographic algorithms. In this paper, a color image encryption algorithm combining the KAA map with multiple chaotic maps proposed. proposed makes full use Shannon’s ideas security, such that carried out through bit confusion diffusion. Confusion employing 2 keys. first key generated from 2D Logistic Sine Linear Congruential Generator, while second Tent Bernoulli map. Diffusion attained An elaborate mathematical analysis showcase robustness efficiency algorithm, as well its resistance visual, statistical, differential brute-force attacks. Moreover, also shown successfully pass all tests NIST SP 800 suite.
