Embodiment Construction

[0017] In the embodiment of the present invention, the node importance index in the two-layer network is first determined according to the characteristics of the complex network, and then the value of the node importance index is arranged from large to small, and the top r% nodes are determined as important nodes, and then the nodes According to the degree of importance and topological position, it is divided into four types: α, β, γ, and μ, and corresponding protection measures are taken for the four types of nodes. Finally, test the robustness of the node and judge whether it meets the requirements. If not, change the size of r and repeat the above steps.

[0018] The present invention will be described in further detail below by means of the accompanying drawings. figure 1 It is a schematic diagram of the implementation flow of the embodiment of the present invention, mainly including the following steps:

[0019] Step 1. According to the given two-layer coupling network t...

Abstract

The invention discloses a novel double-layer coupled network protection method oriented to important node protection, which aims to achieve higher robustness of a double-layer coupled network. The method is characterized in that a node importance evaluation indicator is firstly determined according to characteristics of a network topology; nodes are then sorted according to the indicator; the nodes are classified based on whether the nodes have the function of cross-layer connection or not, and differentiated protection measures are further taken for the classified nodes; and fine adjustments to the proportion of important nodes are constantly carried out to finally achieve better double-layer coupled network protection effects with lower costs.

Description

technical field [0001] The invention belongs to the double-layer coupling network defense and protection technology in complex network security, in particular to a complex network protection method for important node protection based on the diversification of important node attributes. Background technique [0002] With the rapid development of science and technology, the relationship between all walks of life or within the industry is getting closer, so a large number of complex networks coupled with each other have also been produced. For example, power network and subway network, communication network and financial network, etc. Compared with the single-layer network, the sequential fault propagation of these mutually coupled networks is larger in scale, faster in speed and more serious in damage when under attack. Therefore, how to improve the robustness of mutually coupled networks has become the focus of research on the robustness of complex networks. [0003] Gong M...
