Abstract

The invention provides a software-defined Internet of Things network topology data transmission security management method and system, and the method comprises the steps: deploying common nodes and aggregation nodes at Internet of Things network nodes, and enabling the nodes to communicate with each other; performing encryption algorithm configuration on common nodes and aggregation nodes; each adjacent node performing bidirectional identity authentication and key agreement, and each node recording credible nodes passing authentication around itself and suspicious nodes failing to be authenticated; periodically executing topology discovery, collecting topology information of common nodes by the aggregation nodes, forwarding messages of trusted nodes among the aggregation nodes, establishing a trusted path, and constructing a global topology view; sequentially forwarding and aggregating the topology state messages according to the determined trusted path; and determining newly added nodes and malicious nodes based on the global topology view, broadcasting, and updating the network topology structure of the Internet of Things. According to the invention, the security and reliabilityof data transmission can be effectively improved.
