Insider Threats in Wireless Sensor Networks

Abstract— Location-Based Key Management Strong Against Insider Threats in Wireless Sensor Networks. To achieve secure communications in wireless sen-sor networks (WSNs), sensor nodes < Final Year Projects 2016 > SNs must establish secret shared keys with neighboring nodes. Moreover, those keys must be updated by defeating the insider threats of corrupted nodes. In this paper, we propose a location-based key management scheme for WSNs, with special considerations of insider threats. After reviewing existing location-based key management schemes and studying their advantages and disadvantages, we selected location-dependent key management (LDK) as a suitable scheme for our study. To solve a communication interference problem in LDK and similar methods, we have devised a new key revision process that incorporates grid-based location information.
