In this paper, we propose a distributed, reliable and low-power-consumed key-renewal scheme for wireless sensor networks.The proposed scheme is divided into parts: the server part and the sensor-node part.The server will produce an appropriate key-generation function (KGF) for key renewal on sensor nodes under a power consumption constraint.It divides the function into slices and sends the slices to sensor nodes.The sensor nodes will assemble the slices to rebuild the key-generation function for key renewal as they receive the slices.The experimental results also show the effectiveness of the proposed key renewal scheme.
