A Secure Attribute-Based Encryption Framework for Cloud Data Sharing

Abstract

This study endeavors to enhance the security of cloud-based data sharing, safeguard data privacy, and restrict access to it by employing Attribute-Based Encryption (ABE) and other advanced access control technologies. The ABE method enables the protection of data by utilizing an individual's traits rather than their name. Regular encryption methods are not effective in environments with a high volume of users and frequent changes, which is a significant issue with cloud computing. The proposed approach incorporates access controls into the encryption process to ensure that data can only be decoded by individuals who are authorized to do so. It enables the sharing of data among multiple users in a manner that is both scalable and adaptable. This ensures the safety of the system by preventing unauthorized access. This is particularly critical in scenarios where cloud storage providers are not regarded as trustworthy. The system facilitates the rapid and secure management of data by managing key administration, policy changes, and user removal. New tests have demonstrated that it is more effective than conventional encryption methods in terms of safety, speed, and the likelihood of data loss. This renders it an excellent option for existing cloud-based applications.
