Electronic health records (EHRs) aim to improve healthcare efficiency and workload management, but security concerns persist, especially in cloud storage. Proxy re-encryption (PRE) addresses these concerns by allowing authorized intermediaries to convert encrypted data without accessing plaintext. This paper introduces Whale-based Timing Enabled Proxy Re-encryption (WTEPRE), enhancing EHR security in the cloud. WTEPRE employs machine learning to generate keys for encryption and decryption. A designated proxy server re-encrypts data for cloud storage, while a time-seal server regulates file access. Experimental results show WTEPRE’s effectiveness in bolstering security and privacy with acceptable performance.
