An Efficient and Secure Certificateless Authentication Protocol for Healthcare System on Wireless Medical Sensor Networks

Abstract EN

Sensor networks have opened up new opportunities in healthcare systems, which can transmit patient’s condition to health professional’s hand-held devices in time.

The patient’s physiological signals are very sensitive and the networks are extremely vulnerable to many attacks.

It must be ensured that patient’s privacy is not exposed to unauthorized entities.

Therefore, the control of access to healthcare systems has become a crucial challenge.

An efficient and secure authentication protocol will thus be needed in wireless medical sensor networks.

In this paper, we propose a certificateless authentication scheme without bilinear pairing while providing patient anonymity.

Compared with other related protocols, the proposed scheme needs less computation and communication cost and preserves stronger security.

Our performance evaluations show that this protocol is more practical for healthcare system in wireless medical sensor networks.
