Secure Role Based Access Control Data Sharing Approach and Cloud Environment

Abstract

the primary objective of cloud storage is to maintain data integrity, which involves implementing measures to prevent unauthorized access and ensuring that data can be regenerated if mishandled. To achieve this, a proxy server will be assigned the task of protecting and restoring data in case of unauthorized modifications. Users' data will be stored in both public and private areas of the cloud, with only public data being accessible to users and private data being kept more secure. Cloud storage offers users various redundancy configurations to balance performance and fault tolerance, with data availability being critical in distributed storage systems, especially when node failures are common in real-life scenarios. In this research, a proposed aes 128 encryption algorithm and role-based access control (rbac) scheme are explored to provide secure data storage and sharing, as well as a secure user access policy. Additionally, a backup server approach is used as a proxy storage server for ad hoc data recovery for all distributed data servers. The experiment's analysis is proposed in both public and private cloud environments, utilizing keywords such as rbac, elgamal encryption scheme, proxy key generation, advanced encryption standard (aes), and more
