Certificateless Authentication Protocol for Wireless Body Area Network

In order to address the problems of security communication and vital physiological data for WBANs, in this paper, we propose an effective authentication protocol and secure session key generation method. Based on certificateless cryptography, we present a new certificateless encryption scheme and a new certificateless signature scheme, both of that is provably secure and efficiency. Then, taking the above two scheme as a basis, we propose a novel certificateless authentication protocol which is anonymous and mutual authentication. After successful authenticating, an efficient and secure session key is generated at last for subsequent communication in our protocol.
