Abstract:A new generation of WSN communication transceivers are now available that support time-of-flight distance measurement. This measurement can be inseparably integrated with message transmission making it possible to authenticate messages based on distance. In this paper we present a practical implementation of Distance Based Message Authentication (DBMA) for WSNs using Nanotron NA5TR1 transceivers. We show that DBMA can be used to reject messages sent from outside a secure (trusted) area. With DBMA, messages can… Show more
