The emergence of quantum computing marks a revolutionary turning point in the evolution of information technology and cybersecurity. While quantum technologies promise extraordinary computational capabilities capable of solving highly complex scientific and industrial problems, they simultaneously introduce unprecedented risks to the cryptographic foundations that secure today’s digital world. Cloud computing, which has become the backbone of modern digital infrastructure, is particularly vulnerable to these evolving threats. As organizations increasingly rely on cloud platforms for data storage, communication, financial transactions, healthcare systems, research, and critical infrastructure management, ensuring long-term cryptographic security has become an urgent global priority. This book, Post-Quantum Security in Cloud Computing: Challenges and Solutions, has been developed to provide a comprehensive exploration of the rapidly evolving intersection between quantum computing, cloud security, and post-quantum cryptography (PQC). The primary objective of this work is to present both foundational concepts and advanced research perspectives that help readers understand the implications of quantum threats on existing cloud ecosystems and the emerging solutions designed to mitigate them. The chapters in this book collectively examine the vulnerabilities of classical cryptographic systems against quantum algorithms such as Shor’s Algorithm and Grover’s Algorithm, which threaten widely deployed security mechanisms including RSA, Diffie–Hellman, and Elliptic Curve Cryptography. The book further introduces the theoretical and practical foundations of post-quantum cryptography, covering lattice-based, code-based, multivariate, and hash-based cryptographic schemes that are being developed as quantum-resistant alternatives. Beyond theoretical concepts, this book emphasizes practical implementation challenges in cloud environments, including scalability, performance overhead, key management, hybrid cryptographic architectures, secure identity infrastructures, and deployment strategies across distributed and multi-cloud systems. Special attention has also been given to experimental evaluations, benchmarking methodologies, and emerging research directions that will shape the future of quantum-safe cloud security. This work is intended for students, academic researchers, cybersecurity professionals, cloud architects, and policymakers who seek a structured and research-oriented understanding of post-quantum cloud security. By combining theoretical insights with practical perspectives, the book aims to serve as a valuable reference for understanding current developments and preparing for the transition toward quantum-resilient computing infrastructures. The successful completion of this book would not have been possible without the contributions of the global research community working tirelessly in the fields of cryptography, quantum computing, cloud security, and distributed systems. Their groundbreaking research and continuous innovation have inspired many of the ideas discussed throughout this work. It is our sincere hope that this book will contribute meaningfully to the ongoing efforts toward building secure, scalable, and future-ready cloud systems capable of withstanding the challenges of the quantum era.
