Abstract: Electronic health record (EHR) provides us medical information about the patient and provides the overall history of the individual. EHR works automatically. It gives access to health records and workflow of physician. Authentication, timeliness and accessibility to information between doctors and patients are also maintained by this healthcare cryptosystem. The strong cryptosystem consists of doctors' and patients' authentic interaction. Hence, we propose trilinear pairing-based cryptosystem security and authentication using elliptic curve cryptography (ECC) and elliptic curve discrete logarithm problem (ECDLP) techniques. Our proposed model authenticates the patients and doctors by key sharing, transmission and authentication to secure the healthcare system. The analysis outcome shows in the performance, accuracy, time and attacks.

Keywords: electronic health record; EHR; elliptic curve cryptography; ECC; key sharing; authentication; security.
