Multiple-Layer Image Encryption Utilizing Fractional-Order Chen Hyperchaotic Map and Cryptographically Secure PRNGs

Image encryption is increasingly becoming an important area of research in information security and network communications as digital images are widely used various applications vulnerable to types attacks. In this work, a color image cryptosystem that based on multiple layers proposed. For every layer, key S-box generated utilized. These four-dimensional (4D) dynamical Chen system fractional-order, the Mersenne Twister, OpenSLL, Rule 30 Cellular Automata Intel’s MKL. The sequential application Shannon’s ideas diffusion confusion three times guarantees total distortion any input plain image, thereby, resulting totally encrypted one. Apart from excellent comparable performance other state-of-the-art algorithms, showcasing resistance visual, statistical, entropy, differential, known plaintext brute-force attacks, proposed provides exceptionally superior two aspects: vast space 21658 average rate 3.34 Mbps. Furthermore, shown successfully pass all tests NIST SP 800 suite.
