Research on Dynamic Key Management Schemein Wireless Sensor Networks

Wireless sensor networks are widely used in a variety of commercial and military applications due to their self organization characteristics and distributed nature. As a fundamental requirement for providing security functionality in sensor networks, key management plays an essential role in authentication and encryption. In this paper, we propose a group-based dynamic key management scheme in wireless sensor networks. In our scheme, there is no requirement for such infrastructure as base stations and cluster heads in order to maintain the generality and the dynamic key update feature ensures the security of the network without tampering the compromised sensor nodes. We also analyze the connectivity and security of the proposed scheme.
