Abstract

With the development of wireless networks and medical sensors, wireless body area networks are playing more and more important role in the field of healthcare service. The data transmitted in WBANs is very sensitive since it will be used in clinical diagnoses or measurements. Therefore, security and privacy of communication in WBANs derive increasing attentions from the academia and industry. In this paper, we propose an identity (ID)-based efficient anonymous authentication scheme for WBANs using elliptic curve cryptosystem (ECC). Due to the ID-based concept, there is no certificate is needed in the proposed scheme. Moreover, the proposed scheme not only provides mutual authentication between the client and the application provider but also provides client anonymity. Performance analysis shows that improvements of 50.58聽% and 3.87聽% in the client side and the application provider side separately. Then the proposed scheme is more suitable for WBANs.
