Secure and Achievable Heterogeneous Access Control Scheme for Wireless Body Area Networks

Zhaoqi Li, Yuyang Zhou

Abstract: Wireless body area networks (WBANs) play an important role in implementing smart health care. Sensors in WBANs are used to collect and process user-related physiological characteristics data. Only the authorized legal users can access the corresponding resources. So it’s important to guarantee the user’s personal privacy data. In this paper, we design a heterogeneous signcryption scheme (HGSC). In HGSC, sensors in WBANs belong to the identity-based cryptography (IBC) environment and users who want to get the sensor’s data belong to a certificateless cryptography (CLC) environment. According to the HGSC, we propose an access control scheme for WBANs. The scheme is implemented by PBC library, which verifies the heterogeneity of the scheme saves the cryptographic operation time, and has the advantage of computational cost and communication cost compared with the same type of cryptographic scheme.
