To achieve secure communications in wireless sensor networks (WSNs), sensor nodes (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 locationdependent 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. We also propose a key establishment process using grid information. Furthermore, we construct key update and revocation processes to effectively resist inside attackers. For analysis, we conducted a rigorous simulation and confirmed that our method can increase connectivity while decreasing the compromise ratio when the minimum number of common keys required for key establishment is high. When there was a corrupted node leveraging insider threats, it was also possible to effectively rekey every SN except for the corrupted node using our method. Finally, the hexagonal deployment of anchor nodes could reduce network costs.Index Terms-Insider threats, key revision process, locationbased key management, packet drop attack, wireless sensor network (WSN).

“…A sensor node is distributed in an area after storing a single common key k and hash function H. ANs transmit each nonce at a different power level and a sensor node generates single keys as follows : k i j = H k (n i j ). When a sensor node finds common keys whose number is larger than a certain number of keys with a neighbor node, a communication key is derived as [8] proposed SLDK (Sectorized Location Dependent Key Management) in 2009. It reinforces the key resiliency of LDK by adding a scheme that divides the transmit range of an AN into n sectors.…”

To achieve secure communications in wireless sensor networks, sensor nodes should be able to establishsecret shared keys with neighboring parties. The location information of sensor nodes can beused to generate a shared key. In this paper, we propose yet another location-based key managementscheme for wireless sensor networks. After reviewing the existing location-based key managementschemes, we focus on the scheme called LDK because of its pros and cons. To solve a communicationinterference problem in LDK and its similar methods, we devise the new key revision processthat incorporates the grid-based location information. We also propose the key establishment processusing the grid information. For analysis, we conducted a simulation and confirmed that our methodcan increase the connectivity while decrease the compromise ratio when the minimum number ofcommon keys required for key establishment is high. Finally, we also found that hexagonal deploymentof anchor nodes can save network costs in our method.
