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.
