复杂网络局部化攻击的逾渗

Percolation of localized attack on complex networks

Shuai Shao, Xuqing Huang, H Eugene Stanley, Shlomo Havlin

摘要:

复杂网络对节点失效和恶意攻击的鲁棒性研究已经有几十年的历史了,但大多数研究都集中在随机攻击或针对中心节点的攻击上。然而,在许多现实世界的场景中,攻击既不是随机的,也不是以枢纽为目标的,而是局部的,其中网络中的一组相邻节点受到攻击并失败。在本文中,我们开发了一个渗流框架,分析和数值研究的鲁棒性复杂网络对这种本地化的攻击。特别是,我们研究了Erdens-Rényi网络,随机正则网络和无标度网络中的鲁棒性。我们的研究结果为如何更好地保护网络,增强网络安全以及促进更强大的基础设施的设计提供了见解。

英文摘要:

The robustness of complex networks against node failure and malicious attack has been of interest for decades, while most of the research has focused on random attack or hub-targeted attack. In many real-world scenarios, however, attacks are neither random nor hub-targeted, but localized, where a group of neighboring nodes in a network are attacked and fail. In this paper we develop a percolation framework to analytically and numerically study the robustness of complex networks against such localized attack. In particular, we investigate this robustness in Erdős-Rényi networks, random-regular networks, and scale-free networks. Our results provide insight into how to better protect networks, enhance cybersecurity, and facilitate the design of more robust infrastructures.
