Anonymous and Certificateless Remote Data Communication Protocol for WBANs

Abstract

Wireless body area networks (WBANs) is an important branch of wireless sensor networks, which can provide real-time monitoring for patients and home health-care services. Due to the openness of wireless networks, the sensitive physiological information of WBANs users may be revealed during the communication process. Hence, mutual authentication and confidentiality properties are crucial for WBANs. In this paper, an efficient and anonymous remote data communication protocol is proposed, which achieves non-traceability, forward secrecy, session key establishment and non-repudiation. In addition, the proposed protocol transmits physiological information confidentially and achieves mutual authentication at the same time, which can efficiently reduce communication costs.
