论文摘要
网络可控性鲁棒性反映了网络动力学系统能够保持其对破坏性攻击的可控性。本文从恶意攻击的角度研究了网络可控性鲁棒性。通过边缘或节点驱动攻击提出了分层攻击的框架。目标网络中的边缘（或节点）分层分为类别，具有不同的优先级。关键边缘（或节点）的类别具有攻击的最高优先级。在九个合成网络和九个现实世界网络上进行了广泛的实验，显示了拟议的分层攻击策略在破坏网络可控性方面的有效性。从保护的角度来看，这项研究表明，临界边缘和节点应隐藏在攻击者中。这一发现有助于更好地理解网络可控性并更好地设计强大的网络。
Network controllability robustness reflects how well a networked dynamical system can maintain its controllability against destructive attacks. This paper investigates the network controllability robustness from the perspective of a malicious attack. A framework of hierarchical attack is proposed, by means of edge- or node-removal attacks. Edges (or nodes) in a target network are classified hierarchically into categories, with different priorities to attack. The category of critical edges (or nodes) has the highest priority to be selected for attack. Extensive experiments on nine synthetic networks and nine real-world networks show the effectiveness of the proposed hierarchical attack strategies for destructing the network controllability. From the protection point of view, this study suggests that the critical edges and nodes should be hidden from the attackers. This finding helps better understand the network controllability and better design robust networks.
