An Enhanced Key Distribution Scheme for the Energy Consumption and the Security in the Wireless Sensor Networks

The ZigBee which is a type of the sensor networks defines a role of the Trust Center, so it securely communicates through the key distribution. But the key distribution through the Trust Center concentrates all traffic from the Trust Center, so it occurs a delay and an overhead. In this paper, we design a key distribution scheme for secure communication in the wireless sensor networks. It is designed to the Trust Center to Trust Center, the Trust Center to node and the node to node in the proposal scheme. Specially, the proposal scheme through a key distribution between the Trust Centers by reuse the key information improves an energy consumption and a security.
