Secure Neighbor Discovery in Wireless Networks : Is It Possible?
- 2007

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Wireless communication enables a broad spectrum of appli-cations, ranging from commodity to tactical systems.Neigh-bor discovery(ND), that is, determining which devices arewithin direct radio communication, is a building block ofnetwork protocols and applications, and its vulnerability canseverely compromise their functionalities. A number of pro-posals tosecureND have been published, but none haveanalyzed the problem formally. In this paper, we contributesuch an analysis: We build a formal model capturing salientcharacteristics of wireless systems, most notably obstaclesand interference, and we provide a speciØcation of a basicvariant of the ND problem. Then, we derive animpossibilityresultfor a general class of protocols we term \time-basedprotocols," to which many of the schemes in the literaturebelong. We also identify the conditions under which the im-possibility result is lifted. Moreover, we explore a secondclass of protocols we term \time- and location-based proto-cols," and prove they can secure ND
