摘　　要：针对新兴工业互联网因开放、异构、节点众多且资源受限等而面临突出的感知层路由安全困难的问题,提出一种节点角色化的工业互联网感知层安全路由算法。依据功能定位将工业互联网感知层中的节点划分为普通节点、簇首节点、汇聚节点和安监节点4种角色,建立起融合节点角色化和随机巡查的安全信誉评估方法,形成基于节点信誉评估的感知层分簇拓扑,融合节点安全信誉评估方法和Dijkstra算法优化建立工业互联网感知层安全路由。仿真结果表明,提出的算法对工业互联网感知层恶意节点的发现准确率可达到94%,有助于提升工业互联网感知层的路由安全。The emerging industrial Internet is facing an outstanding difficulty in secure routing of sensing layer because of its openness,non-homogeneity,numerous nodes and restricted resources.A secure routing algorithm for sensing layer of industrial Internet based on roles of nodes is proposed.According to the functional demands,the nodes in sensing layer of industrial Internet are divided into four roles such as common node,cluster head node,aggregation node and security supervision node.The secure reputation assessment method is built by fused roles of nodes and random inspection.The topology of clustered sensing layer is reached based on the reputation assessment of nodes.And nodes secure reputation assessment method and the Dijkstra algorithm are integrated to optimize secure routing for the sensing layer of industrial Internet.The simulation results show that the detection accuracy of the proposed algorithm for malicious nodes in the perception layer of industrial Internet can reach 94%,which suggests that the proposed method is helpful to improve the routing security of sensing layer of industrial Internet.
