Ubiquitous network topological graph construction method and network security protection method

Abstract

The invention provides a ubiquitous network topological graph construction method and a network security protection method. The construction method comprises the following steps: determining a to-be-constructed ubiquitous internet; constructing a ubiquitous network topological graph based on atomic operation by taking communication subjects in the ubiquitous internet as nodes and taking a relationship among the communication subjects as edges; wherein the nodes comprise an end node, a collection access node and a control node; the atomic operation is used for adjusting nodes and / or edges, the atomic operation comprises at least one of intersection operation, union operation and fusion operation, and network security protection capability arrangement, deployment and management, threat disposal and network security supervision can be carried out based on the atomic operation. According to the method provided by the invention, the ubiquitous network topological graph is constructed through the universal, minimum and combinable atomic operation, so that the ubiquitous network topological graph can adapt to the large-scale and high-dynamic characteristics of the ubiquitous internet, network security protection is carried out on the basis, and the security and completeness of the network security protection are ensured.

Description
