摘　　要：工业物联网中节点资源受限,数据融合是减少能耗最重要的技术之一。为了保障工业物联网中数据在融合过程的安全性,提出一种基于监督机制的工业物联网安全数据融合方法。首先将采集的数据映射成模式码后进行融合和传输,保证了数据的机密性;其次通过监督节点对融合节点进行监督来保证融合信息的安全性;最后通过博弈论证明了监督报文上传方式的安全性和合理性。安全分析和性能仿真表明在保证安全属性的前提下,降低了通信开销和存储开销。并在已有的WIA-PA协议栈的基础上搭建工业物联网安全平台,实现安全数据融合功能。The node resources are constrained in industrial Internet of Things ; data fusion is one of the most important techniques to reduce energy consumption. This paper presents a secure data fusion method in industrial Internet of Things based on supervisory mechanism in order to ensure the security of data fusion in industrial Internet of Things. Firstly, the acquired data are mapped to pattern codes, which are fused and transmitted;and the confidentiality of the data is ensured. Secondly, the fusion nodes are supervised by the supervision nodes to ensure the security of data fu- sion. Finally the safety and rationality of the upload mode of supervision message are proved with the game theory. Se- curity analysis and simulation analysis indicate that under the premise of ensuring the security attributes, the commu- nication and storage overheads are reduced. On the basis of existing WIA-PA protocol stack, an industrial Internet of Things security platform was built, which realizes the fusion function of safety data.
