ABSTRACT

The integration of quantum cryptography and blockchain offers a transformative approach to enhance data security in cloud environments. Quantum cryptography, leveraging principles of quantum mechanics such as quantum key distribution (QKD), ensures unbreakable encryption by enabling secure key exchange. Simultaneously, blockchain technology introduces decentralization, transparency, and immutability, ensuring data integrity and preventing unauthorized tampering. This research explores the synergy between these technologies to develop a novel framework for cloud security. The proposed model leverages QKD for secure communication channels and blockchain-based distributed ledgers for verifying transactions and access control. Key contributions include a hybrid encryption mechanism using quantum keys, a consensus algorithm optimized for cloud operations, and integration strategies to mitigate quantum attacks. Performance evaluations demonstrate enhanced resilience against data breaches, improved key management, and seamless scalability for modern cloud architectures. This study establishes a secure, future-proof infrastructure that addresses emerging threats in the post-quantum era while ensuring trust, confidentiality, and data integrity in cloud ecosystems.

Significance of the Study:

This study is highly significant as it pioneers a hybrid security framework combining quantum cryptography and blockchain technology to address emerging threats in cloud environments. By leveraging Quantum Key Distribution (QKD) for unbreakable encryption and blockchain for transparency and data integrity, the study establishes a robust defense against both classical and quantum attacks. Its contributions to secure key management, authentication, and breach detection set a foundation for future-proof, scalable, and resilient cloud security systems in the post-quantum era.
