A Dynamic Keys Management Policy for Mass Wireless Sensor Networks
Zengzhi Li · Dianzi xuebao · 2008
For solving the issue of keys management in the mass wireless sensor networks,a Two-Level Key Management Scheme which will be used in clustered sensor networks based on EBS system was proposed.This scheme runs from network's deployment to the end of lifecycle,to manage all of the nodes' keys.Regarding of the specialty of sensor networks,this scheme consists of three phases which are initialization phase,working phase and update phase.The experiments show that the sensor nodes only need to store fewer keys and the whole network performs good ability in keeping network flexibility.
