Quantum Cryptography-Enabled Cloud Security (QCECS) Framework

Wassan Adnan Hashim

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.

Leveraging Quantum Cryptography And Blockchain For Strengthened Data Security In Cloud Infrastructures

Srinivasan J., Sindhu Achuthankutty, R. Rajkumar +3 more

The rapid adoption of cloud infrastructures has intensified concerns regarding data confidentiality, integrity, and trust management, particularly in the presence of emerging quantum computing threats. Classical cryptographic mechanisms, which underpin most existing cloud security architectures, are increasingly vulnerable to quantum attacks capable of compromising public-key encryption and key exchange protocols. To address these challenges, this paper proposes a hybrid security framework that integrates Quantum Cryptography with Blockchain technology to achieve robust, future-resistant data protection in cloud environments. The proposed framework leverages Quantum Key Distribution (QKD) to enable provably secure key generation and exchange based on quantum mechanical principles, ensuring resistance against eavesdropping and computational attacks. Blockchain technology is employed to provide decentralized trust, immutable audit trails, and transparent access control across distributed cloud services. Smart contracts enforce fine-grained security policies, automate authentication, and ensure tamper-proof data access logging. The synergy between quantum cryptography and blockchain establishes a secure key lifecycle, resilient identity management, and verifiable data integrity within multi-tenant cloud infrastructures. Comprehensive security analysis demonstrates that the proposed approach effectively mitigates quantum-enabled attacks, insider threats, and single-point-of-failure vulnerabilities commonly found in traditional cloud security models. Experimental evaluation and comparative analysis highlight improvements in data integrity assurance, key management robustness, and trust transparency, with acceptable computational and communication overhead. The results indicate that integrating quantum cryptography with blockchain presents a scalable and future-proof security paradigm for next-generation cloud infrastructures.

Post-Quantum Cryptography Security with CSPM for Secure Data Transmission in Cloud Environments

N. Rajkumar, Kishore Kumar K, M. Gokul +1 more

Quantum computing poses a significant threat to traditional cryptographic systems, necessitating the exploration of robust alternatives to secure data transmission in the cloud. This abstract delves into the integration of Post-Quantum Cryptography (PQC) and Cloud Security Posture Management (CSPM) as a comprehensive solution. The proposed framework advocates for the adoption of a variant of the McEliece cryptosystem within the cloud infrastructure, providing resistance against potential quantum attacks. Encryption, fortified by Post-Quantum Cryptography, emerges as the dominant method for ensuring the security of cloud-stored data. In parallel, Cloud Security Posture Management (CSPM) is introduced as a set of security protocols designed to identify and remediate cloud misconfigurations, enhancing the overall security posture. This research highlights the synergy between PQC and CSPM, showcasing their collective effectiveness in mitigating emerging threats in cloud computing. The integration of Quantum Key Distribution (QKD) further enhances data security, ensuring the confidentiality and integrity of transmitted information. The proposed model not only addresses current data breach challenges but also anticipates the evolving landscape of quantum computing, providing a forward-looking solution for secure data transmission in cloud environments.
