Distributed Node Authentication in Wireless Sensor Networks

Authentication is necessary to not only data exchange processes but also network administrative tasks in Wireless Sensor Networks. So far, only data authentication has drawn much attention from the research community. We propose an efficient Distributed Node Authentication (DNA) scheme that utilizes geographic location and trust relationship among neighboring sensor nodes to authenticate the identity of sensor nodes. Analysis and simulation results demonstrate that DNA is robust against node failure/sleeping and resilient to network attackers.
