FRDNAC: A Future-Ready DNA Cryptography Paradigm for Secure Cloud Data Transmission Using Deep Learning-Enhanced Key...

The growing reliance upon cloud settings has rendered secure transmission of information essential. This study introduces the future-ready DNA-based cryptography (FRDNAC) paradigm, which combines DNA-based encryption with the feedback-assisted archimedes optimization algorithm to achieve efficient key generation and improved security. FRDNAC was assessed in comparison to contemporary optimization approaches such as the feedback artificial tree, the archimedes optimization algorithm, the blue monkey optimization, the coot optimization algorithm, the butterfly optimization algorithm, the shark smell optimization, the whale optimization algorithm, and the lightweight encryption system, as well as traditional encryption methods such as DNA encryption, Blowfish, Rivest-Shamir-Adleman (RSA), the advanced encryption system, and the elliptic curve cryptography. Experimental findings demonstrate FRDNAC's exceptional encryption and decryption efficacy, achieving an encryption duration of 0.11 s (key length 4.0), surpassing rivals like FAT (0.29 s) and LES (0.20 s). Furthermore, FRDNAC markedly enhanced memory efficiency, rendering it suitable for resource-limited cloud settings. Security evaluations indicate its robustness against cryptographic threats, encompassing known-plaintext attack, chosen-plaintext attack, and brute force attack. Despite obstacles in real-time key generation and computational cost, FRDNAC presents itself as a highly safe and efficient cryptographic framework appropriate for cloud-based applications. Its strong security framework establishes it as a viable solution for sectors requiring high-performance encryption in evolving digital environments.
