Secure Walking GPS: A Secure Localization and Key Distribution Scheme for Wireless Sensor Networks

In many applications of wireless sensor networks, sensor nodes are manually deployed in hostile environments where an attacker can disrupt the localization service and tamper with legitimate in-network communication. In this paper, we introduce Secure Walking GPS, a secure localization and key distribution solution for manual deployments of WSNs. Using the location information provided by the GPS and inertial guidance modules on a special master node, Se- cure Walking GPS achieves accurate node localization and location-based key distribution at the same time. Our anal- ysis and simulation results indicate that the Secure Walking GPS scheme makes a deployed WSN resistant to the Dolev- Yao, the wormhole, and the GPS-denial attacks, has good localization and key distribution performance, and is prac- tical for large-scale WSN deployments.
