Book

In the rapidly evolving landscape of cybersecurity, the emergence of sophisticated cyber threats and quantum computing technologies has exposed the limitations of conventional encryption techniques in safeguarding sensitive cloud data. DNA-Based Cryptography for Cloud Security presents a pioneering and future-oriented approach to secure computing by integrating DNA-inspired cryptographic principles, Artificial Intelligence, Machine Learning, and post-quantum security mechanisms into a unified cloud protection framework. This book introduces the innovative Variational DNA-Based Data Security (VDNABDS) protocol, a next-generation cryptographic architecture designed to deliver high-performance, scalable, and quantum-resilient cloud security. By leveraging dynamic DNA sequence generation, intelligent key transformation, DNA-XOR operations, Fisher–Yates randomization, and hybrid ECC-RSA encryption strategies, the proposed framework achieves enhanced entropy, rapid key generation, lower computational overhead, and superior resistance against brute-force and quantum-based attacks. The book provides comprehensive coverage of advanced topics including DNA computing for cryptography, bio-inspired encryption models, intelligent cloud security architecture, AI-assisted encryption optimization, IoT-aware secure communication, post-quantum cryptographic resilience, and scalable multi-user cloud protection systems. Detailed experimental evaluations, comparative analyses with traditional encryption methods such as AES and RSA, and real-world simulation studies demonstrate the effectiveness, adaptability, and practical viability of the proposed framework in modern cloud environments. Designed for researchers, academicians, cybersecurity professionals, cloud engineers, and students, this book serves as both a theoretical foundation and a practical guide for developing next-generation intelligent security systems. By bridging biological computing concepts with modern cryptographic engineering, DNA-Based Cryptography for Cloud Security contributes toward the advancement of secure, adaptive, and future-ready digital infrastructures for the era of intelligent computing.
