Yagan, OsmanMakowski, Armand M.The pairwise key distribution scheme of Chan et al. was proposed as an alternative to the key distribution scheme of Eschenauer and Gligor to enable network security in wireless sensor networks. We consider the random graph induced by this pairwise scheme under the assumption of full visibility, and show the existence of a zero-one law for graph connectivity.en-USWireless sensor networksSecurityKey predistributionRandom key graphsConnectivityZero-one lawsTechnical Report
