To achieve security in wireless sensor networks, encrypted messages using keys shared among sensor nodes are used. In ZigBee, SKKE protocol is used to distribute the key from the trust center to end devices. However, due to resource constraints, low power key distribution schemes are essential to the wireless sensor networks. In this paper, we propose a method that applies network coding technique to share the security key. The proposed scheme decrease the energy consumption of the nodes and reduces the time delay.
