A Lightweight Trust-based Access Control Model in Cloud-Assisted Wireless Body Area Networks

The integration of Wireless Body Area Networks (WBANs) with cloud computing will enable users (including physicians and nurses) to globally access the electronic healthcare data at competitive costs. However, some new issues on data access control are associated with the integration of WBANs and cloud computing. In order to address these issues, we propose a lightweight trust-based access control model, where the users can acquire their access control privileges for the electronic healthcare data according to the user role and trust value in the trust certificates. Simulation results show that our method can better alleviate the communication overhead and energy consumption problem.
