The robustness of interdependent networks has attracted much attention recently. Existing studies mainly focus on random failures, however, targeted attacks are ubiquitous in the real world. In this paper, a low degree neighbor node priority coupling (LDNPC) strategy is proposed, which enhances the robustness of interdependent networks under high-degree node targeted attacks by changing the relationship between layers to generate structures of overlapping links. First, nodes are ranked in descend according to their degrees. Then, nodes with low degrees have priority to choose their dependency partners to generate structures of overlapping links. Finally, experiments on three models of interdependent networks show that LDNPC can enhance the robustness of interdependent networks against high-degree node targeted attacks effectively.

一种基于重叠链路结构的相互依赖的网络耦合策略对抗针对性攻击

相互依赖网络的鲁棒性最近引起了很多关注。现有的研究主要集中在随机故障上，然而，有针对性的攻击在现实世界中无处不在。在本文中，提出了一种低度邻居节点优先耦合（LDNPC）策略，通过改变层之间的关系来生成重叠链接的结构，从而增强相互依赖的网络在高度节点针对性攻击下的鲁棒性。首先，节点根据其度数按降序排列。然后，度数低的节点优先选择它们的依赖伙伴来生成重叠链接的结构。最后，对三种相互依赖网络模型的实验表明，LDNPC可以有效地增强相互依赖网络对高度节点针对性攻击的鲁棒性。
