Efficient Certificateless Access Control for Wireless Body Area Networks - 2016
Wireless body space networks (WBANs) are expected to act as an important role in monitoring the health info and creating a highly reliable ubiquitous healthcare system. Since the data collected by the WBANs are used to diagnose and treat, only licensed users can access these data. So, it is necessary to design an access control scheme which will authorize, authenticate, and revoke a user to access the WBANs. During this paper, we initial give an efficient certificateless signcryption theme and then design an access control scheme for the WBANs using the given signcryption. Our theme achieves confidentiality, integrity, authentication, non-repudiation, public verifiability, and ciphertext authenticity. Compared with existing 3 access management schemes using signcryption, our theme has the least computational cost and energy consumption for the controller. Likewise, our theme has neither key escrow nor public key certificates, since it's primarily based on certificateless cryptography.
