Abstract

For address the issue of key management in the large-scale wireless sensor networks, we propose TLKMS(Two-Level Key Management Scheme)which will be used in clustered sensor networks based on EBS system. In this paper, we show the detail of dynamic keys management scheme which has master and slayer two levels. It works from the deployment of sensor nodes to the end of networks to manage all of the sensor nodes’ keys. And regarding of the specialty of sensor networks, the scheme is separated to three phases which are initialization phase, steady phase and update phase. The experiment shows that the sensor nodes in our scheme only need to store fewer keys and the whole network performs good ability in keep network elasticity.
