Optimization with Blockchain based Secure Authentication and Collaborative Data Sharing Model in Cloud

Cloud computing has become a critical technology to meet infrastructure and data service needs cost-effectively, with minimal effort, and with a high degree of scalability. It is widespread in many facets. Although the use of cloud computing has increased significantly, concerns about information security have not yet been fully addressed. With the exponential growth of cloud computing, many new web services have emerged, making it difficult for customers to choose the services they want. This research study has attempted to create a powerful framework for data exchange called blockchain-based secure authentication and collaborative data sharing in the cloud to overcome this hurdle. The entities used in this research are third parties, data owners, smart contracts, and blockchain networks. The steps involved in this process are initialization, registration, authentication, data sharing, and decryption. The safety operators are created using Fire Hawks Optimization (FHO). In addition, the evaluation metrics are revenue, storage usage, and compute costs. Finally, the results proved that FHO-based OptiBC-SecAuth-DS achieved maximum revenue, minimum storage usage, and minimum computational costs.
