A secure protocol for patient monitoring in wireless body area networks

Abstract

Recently, an authentication scheme was presented for health-care in IoT for WBANs by Fotouhi et al. Authors asserted their scheme to be free from a number of attacks.Here, we find that Fotouhi et al.'s scheme suffers from insider attack, fails to provide proper authentication and bears inefficient password update phase. Therefore their scheme has security pitfalls that can lead to further security breaches. We remove the weaknesses of Fotouhi et al.'s scheme and hence propose a user authentication scheme for patient care. Our scheme is suitable for providing special care to patients in the healthcare industry. The proposed scheme facilitates health professionals to access the real-time data of patients under treatment for some diseases.It also safeguards the medical staff from catching an infection from the patients by minimizing the need to come in direct contact with the patients. We justify the security of our proposed scheme by applying the random oracle model to it. The proposed scheme is compared with some related works to judge its efficacy over the compared counterparts.
