Attribute-Based Proxy Re-encryption Using Revocation Mechanism for Data Sharing in Cloud
摘要
Cloud computing's computational power and scalability have made it an essential infrastructure. However, when outsourcing data to cloud servers, secure data sharing continues to be a significant concern. A promising approach that permits encrypted data sharing while imposing fine-grained access control is provided by attribute-based proxy re-encryption, or ABPRE. The absence of an effective revocation mechanism is a significant drawback of current ABPRE systems, making it challenging to control access after users are deleted. In order to improve security and preserve computational efficiency, this research suggests a safe ABPRE scheme with a revocation mechanism. Results from experiments show that our plan ensures smooth access control while achieving lower overhead.
