Abstract
The paper addresses key challenges in e-healthcare systems, where encrypted personal healthcare records (PHRs) enhance privacy but hinder effective data utilization. Additionally, the need for doctors to be online during treatment is often impractical. The proposed solution, DSAS (Dynamic Secure Access Scheme), is a secure proxy searchable re-encryption scheme that ensures:1. Privacy and Confidentiality: PHRs are encrypted before uploading to the cloud server, safeguardingpatient data.2. Controlled Access: Only authorized doctors or research institutions can access the encrypted PHRs.3. Delegation of Responsibilities: The doctor-in-charge (Alice) can delegate access to a proxy (Bob) or research institutions through the cloud server, minimizing data exposure.The scheme formalizes security definitions and provides rigorous proofs of its security. Performance evaluations validate the efficiency of DSAS, ensuring safe, practical, and effective remote monitoring and research of PHRs in e-healthcare systems
