Abstract: Wireless body area network (WBAN for short) is a great technological progress for modern medical treatment. People at home can send their real-time body data (e.g., heart rate) to remote monitoring station for further knowledge of his body. Due to the openness of the wireless channel and the sensitivity of human body data, it is very important for WBAN to build secure and efficient authentication schemes. Accordingly, there appeared several anonymous authentication schemes for WBAN. However, these existing schemes have some limitations, such as overhead costs and untraceability. In this paper, we first present a novel revocable certificateless public key encryption (RCL-PKE) scheme, which is IND-CCA secure under the random oracle model. Furthermore, based on the RCL-PKE scheme, we propose an efficient revocable remote anonymous authentication scheme for WBAN, which can provide the traceability of the client identity when there appears a medical dispute.
Keywords: revocable; certificateless; remote anonymous authentication; wireless body area network; WBAN.
