A spatial role-based authorization framework for sensor network-assisted indoor WLANs

In this paper, we propose a spatial role-based authorization framework which specifies authorization based on both role and location constrains in a wireless local area network with assistance from a sensor network. The framework performs a location-restricted verification scheme before granting a user with privileges for crucial resources access. Analysis and simulation results show that our framework can provide double-check safeguard to confidential information, so that potential attackers cannot access the resource outside the permitted region, even though their role is verified.
