An Improved ID-Based Key Management Scheme in Wireless Sensor Network

Key management is one of the critical areas in WSN as limited resources of sensor nodes restrict the use of conventional security techniques. Most of the sensor networks use shared key among all the nodes to make communicational overhead minimal. But it is vulnerable to many attacks like stolen-verifier attack, replay attack, node-compromise attack etc. In this paper, we propose an efficient ID-based key management scheme using bilinear pairings. Our ECC based scheme requires light computational and communicational load and resist the major attacks in Wireless Sensor Network.
