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 protocol has some security weaknesses for newly joining devices. In this paper, these weaknesses are analyzed and a novel elliptical curve identity-based cryptography (ECIC) protocol is presented to improve the security level of ZigBee networks. The proposed method provides perfect forward secrecy and enables network key transmission between nodes. Therefore, the traffic concentrated on the trustcenter is diminished, and the network efficiency is improved by reducing the key establishment time and processing burden on each sensor node, thereby reducing the overall energy consumption of the sensor network.
