Improved Attribute-Based Encryption Approaches in Cloud Security

Abstract

Depending on the amount of danger and requirement, cloud-based applications are classed into three severity levels: low, medium, and high. Using Attribute-Based Encryption (ABE) for individualised security, it specifies the recommended encryption methods for every class. Given the gravity of the consequences that might result from data breaches or system failures, mission-critical applications like real-time medical records require strong ABE with granular access control. With ABE and approved outsourced decryption, they are able to strike a balance between cost and security for medium-critical applications, such as cloud storage. Simple ABE encryption is sufficient for non-critical apps, such as those that help customers discover restaurants. In order to strengthen authentication utilising a two-layer approach and reduce vulnerability to insider attacks, a modified ABE methodology is designed that employs digital signatures and hash functions. In addition to evaluating its effect on performance, the plan includes testing the algorithm's robustness in cloud-based settings. We will evaluate the algorithm's performance with real-time cloud applications in our future study.
