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

Abstract

Abstract-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 doublecheck safeguard to confidential information, so that potential attackers cannot access the resource outside the permitted region, even though their role is verified.
