Color Image Cryptosystem Based on Sine Chaotic Map, 4D Chen Hyperchaotic Map of Fractional-Order and Hybrid DNA Coding

With advancements in computer and communication technologies, the production, utilization applications of digital images is at an unprecedented rate. Recent include military communications, remote sensing, novel engineering designs storage as well medical imaging. In most cases, such convey highly sensitive or confidential information, which creates a strong need for design secure robust color image cryptosystems. literature has shown that fractional-order functions exhibit improved performance over their corresponding integer-order versions. This especially true use processing applications. this research work, we make four-dimensional (4D) hyperchaotic Chen map fractional-order, conjunction with sine chaotic hybrid DNA coding algorithm. A thorough numerical analysis presented, showcasing security efficiency proposed cryptosystem. Performance gauged terms resilience against visual, histogram, statistical, entropy, differential, brute-force attacks. Mean values metrics computed are follows. MSE 9396, PSNR 8.27 dB, information entropy 7.997, adjacent pixel correlation coefficient 0, NPCR 99.62%, UACI 33, MAE 80.57, very large key space 2 744 . The cryptosystem exhibits low computational complexity, it encrypts rate 4.369 Mbps. Furthermore, passes NIST SP 800 suite tests successfully. Comparison those reported state-of-the-art by counterpart algorithms show comparable superior values.
