Abstract

The introduction of cloud technology changes the face of data management by eliminating tedious concerns with regards to proper storage and accessibility as it can done from any location, therefore, it can be said that the emergence of this technology came with a number of challenges related to data confidentiality, integrity, and authentication as well. As a resolution to certain weaknesses presented in this case, the authors in this paper suggest a hybrid security model which integrates both quantum cryptography and blockchain technology, and improves security flaws on cloud and quantum models. There are three characteristics of data that are crucial to its safety and security; confidentiality, integrity, and availability, and cloud technology has been known to be accompanied with plenty of challenges concerning these aspects, however, with the use of Blockchain technology, data becomes immutable, decentralized, and transparent thereby reducing the risk of unauthorized access. The combination of strategies proposed in this paper, helps to eliminate a number of drawbacks like key loss, data loss, and man in the middle attacks that are common in cloud infrastructure. This study shows the structural design, data transmission and processes of the architecture for the hybrid model, looking forward to achieve better data security. The analysis of the model suggests its advantages over conventional encryption model and a purely constructed model of blockchain. Performance benchmarks are also included, demonstrating that the model is resilient to cyber threats during the quantum age. The architecture is seamless with the current cloud stature, takes cloud security a notch higher by solving the considerable challenges and is poised to be deployed on a larger scale The directional works will include improving the system’s computational efficiency and extending the model to multiple cloud infrastructures to achieve higher security in today’s complex cloud systems.
