QUANTUM-SAFE ENCRYPTION FOR CLOUD SERVICES: A NEW ERA OF DATA PRIVACY

Abstract

As significant advances are being made in quantum computing, existing cryptographic protocols for cloud security such as RSA ECC and AES are under thread from powerful quantum computing capabilities like such as Shor’s and Grover’s algorithm. The study, "Quantum-Safe Encryption for Cloud Services: A New Era of Data Privacy" examines the threats associated with existing limitations of encryption protocols at the advent of quantum years. This study analyzes the various methods of Post-Quantum Cryptography (PQC) that are available to protect against attacks from quantum threats including lattice-based, code-based, hash-based, multivariate polynomial, and isogeny-based methods. This paper also examines the framework for Quantum Key Distribution (QKD) protocols such as BB84 and E91 and the proposed umbrella methodology for cloud data protection by utilizing both PQC and traditional encryption. It provides examine a framework for the implementation of their methodology along with potential future directions including Blockchain-Based frameworks, integration of AI and standards-based protocols. This study emphasizes the urgent and immediate need for quantum-safe encryption, which is vital for the long-term confidentiality and privacy of cloud-based data services in future.
