Trustworthy access control for wireless body area networks

Wireless body area networks (WBANs) are expected to play an important role in monitoring the health information and creating a smart, reliable, and ubiquitous healthcare system. Only authorized users can access the network since the collected data by the WBANs are used to diagnosed and treated. However, the lack of a clear in-depth defense line in such a new networking paradigm would make its potential users worry about the leakage of their private information, especially to those unauthenticated or even malicious adversaries. Here proposed a novel certificateless signcryption scheme, and then, design a cost-effective and reliable access control scheme for the WBANs using the novel signcryption. The proposed access control scheme achieves anonymity, confidentiality, authentication, integrity, and non-repudiation.
