Abstract
The deep coupling within the interdependent networks may cause a series of serious network security problems, and even lead to the collapse of the networks completely. In order to study the influence of the coupling on the interdependent networks, this paper constructed the model of interdependent networks and analyzed its robustness, which is used to evaluate the security of interdependent networks. Firstly, inspired by the logistics-warehouse, we proposed three kinds of interdependent networks models: positive correlation model, negative correlation model and random correlation model, which are based on closeness centrality of the nodes. Secondly, we analyzed the impact of different attack strategies, dependent ways, dependent probability on the robustness. Experimental results show that the three models are more sensitive to deliberate attacks; the robustness of the negative correlation model is the strongest; and the robustness can be enhanced by appropriately increasing the dependent probability. Finally, according to the experimental results, we put forward some defense strategies on constructing interdependent networks and maintaining its security.
