摘要：

The smart grid has caught great attentions in recent years, which is poised to transform a centralized, producer-controlled network to a decentralized, consumer-interactive network that's supported by fine-grained monitoring. Large-scale WSNs (Wireless Sensor Networks) have been considered one of the very promising technologies to support the implementation of smart grid. WSNs are applied in almost every aspect of smart grid, including power generation, power transmission, power distribution, power utilization and power dispatch, and the security of 'WSNs in power grid' become an hotspot issue due to the data of power grid is important and sensitive. In this paper, the monitoring system of the power transmission and distribution based on WSNs is well studied, and the cluster based network model is constructed. On this basis, an efficient ternary polynomial based key management framework is proposed, which is scalable and effective in cluster based wireless sensor networks. The analysis shows that proposed scheme can meet the security requirement of key management, and it also has less communication cost, computation cost and storage cost compared with other popular algorithms.
