Abstract

ZigBee uses the network security and application profile layers of the IEEE 802.15.4 and ZigBee Alliance standards for reliable, low-powered, wireless data communications. However, the ZigBee has problems of being less secure, and has a difficulty in distributing shared symmetric keys between each pair of nodes. In addition, the ZigBee protocol is inadequate for large sensor networks, which may consist of several very large scale clusters. In this paper, we first construct a secure ZigBee scheme for realistic scenarios consisting of a large network with several clusters containing coordinators and numerous devices. We present a new key management protocol for ZigBee networks, which can be used among participants of different clusters and analyze its performance.
