Securing Positioning With Covert Base Stations [Report]

NESL Technical Report #: 2005-3-1

Authors:

Abstract: Until recently, the problem of positioning in wireless networks has been mainly studied in a non-adversarial setting. Recently, several solutions to this problem have been proposed which mainly rely radio on (RF) signal propagation times and require highly sophisticated hardware. In this work, we propose a new approach to secure positioning, based on covert base stations. Our system enables secure positioning with a broad spectrum of positioning techniques: ultrasonic or RF, based on received signal strength or on signal time of flight. We show that security of our system depends on the precision of the positioning systems and on the size of positioning regions. We generalize this notion and capture this dependence analytically. We further show how our system can be applied to secure positioning in sensor networks.
