In the Internet of Things( IoT),the property of multi-source and heterogeneity bring more challenges to its security.In order to attain cross-layer security control and deploy multi-layer combined security control strategy,an algorithm based on spectral clustering is proposed to divide nodes into several security domains. In the algorithm, through statistics about which sensor nodes are involved in history security events,correlations of sensor nodes to history events are calculated and then nodes are divided accordingly using spectral clustering method.The dipartition can serve strong support for deployment of security control strategy within domain and between different domains, thus improve overall security level of IoT.
