A Secure E-Medical Exemption System (E-MES): Jordan Case

In this paper, a new secure EMedical Exemption System Based on Elliptic Curve Public Key Cryptography is proposed. This study specifies the medical exemption system in Jordan. However, the proposed system is summarized into three phases: first, the hospital process for applying the patient's application and producing the medical report. Second, the Royal Hashemite Court (RHC) process, which receives the hospital report, will then send a request to the ministry of health, the income and sales tax department, and the ministry of social development in order to check the patient's condition for a medical exemption. In fact, this aim of this step is to ensure that the patient is not able to bear the cost of treatment. Third, the RHC will send the decision to the patient via a short message. In practice, this E-medical system is more efficient than the traditional medical protocols since the patient can apply for a medical exemption directly from the hospital without suffering of any extra cost. Therefore, the elliptic curve public-key encryption and digital signature system ensures and guarantees the security of the proposed protocol. Nonetheless, to prevent a brute force attack, the choice of the key size becomes crucial.
