Role-based Access and Advanced Encryption Techniques Ensure Cloud Data Security in Data Deduplication Schemes

The proliferation of cloud-based storage solutions has accentuated the need for robust security mechanisms. This research delved into enhancing cloud storage security by intertwining advanced client-side encryption with Role-Based Access Control (RBAC). Empirical evaluations revealed the encryption's consistent ability to produce unique ciphertexts for data, ensuring heightened confidentiality and resilience against unauthorized decryption. Concurrently, RBAC streamlined access controls, dynamically grouping users into predefined roles with associated permissions. Furthermore, our deduplication tests underscored the system's prowess in optimizing storage, significantly reducing redundancy while preserving data integrity. The RBAC system's performance metrics, even under varying loads, confirmed its scalability and efficiency. While the proposed blend of encryption and RBAC demonstrated substantial advancements in ensuring data security and storage efficiency, the results also hint at potential avenues for future refinement and research in the ever-evolving cybersecurity landscape.
