A Novel Secure Key Management Scheme for Wireless Sensor Networks Using Post Deployment Knowledge

Shah Alam [2] | Rajendra Kumar Seth [2]


Abstract: The wireless sensor networks are resources constraint networks. The security is most major apprehension in wireless sensor networks. The traditional cryptographic schemes are not suitable for the resource constraints sensor networks. Many key management schemes are especially designed to overcome the constraints of wireless sensor networks. Each and every key management schemes are some tradeoff between limited resources and security. The most of the key management schemes are depends upon the deployment knowledge to improve the connectivity and resilience of the network. In this proposed hierarchical key management scheme, we divide the deployment field into tracks and sector and the keys are generated and distributed based on hop count, track and sector ID. For the construction of tracks and sectors, are carried out by base stations at the beginning of the network initialization. So the security as well as energy efficient key management scheme can be achieved. The proposed scheme dynamically generates keys among sensors based on sector and sensor location ID. Our improved scheme offers high resilience, connectivity and reduced energy consumption without any additional overhead
