Quantum Cryptography-Enabled Cloud Security (QCECS) Framework

The QCECS Framework is ready to prevent new types of threats in the cloud environment given the increasing threat potential of quantum computing. RSA and ECC conventional encryption techniques cannot protect data security from quantum penetration and, therefore, the need for quantum security models. This incorporates the QKD for the impenetrable key exchange, post-quantum cryptography for data scrambling, blockchain for a more transparent way of managing keys, and the use of Artificial intelligence for real-time intrusion detection especially for traditional as well as quantum threats. At the same time, the proposed framework forms a symmetrical hybrid encryption approach with both quantum-resistant and classical interference to deliver the best outcomes while maintaining security integrity. The evidence derived from the study indicates that the framework protects the data through cryptographic mechanisms such as lattice-based cryptography and QKD and key management is secured through blockchain. It is crucial to mention, that the application of AI improves the detection of new threats in process and real time. This framework provides higher encryption strength, clarity, and quantum security compared to other methods. Even though various obstacles are resolved in the framework, several barriers remain in terms of hardware access, cloud adaptability, and internal enhancement. Yet, due to its novel approach to post-quantum cybersecurity, it has become a potential dominating solution for future cloud security.
