Abstract

Measuring the impact of network attack is an important issue in network science. In this paper, we study the impact of maximal vertex coverage (MVC) attack in large complex networks, where the attacker aims at deleting as many edges of the network as possible by attacking a small fraction of nodes. First, we present two metrics to measure the impact of MVC attack. To compute these metrics, we propose an efficient randomized greedy algorithm with near-optimal performance guarantee. Second, we generalize the MVC attack into an uncertain setting, in which a node is deleted by the attacker with a prior probability. We refer to the MVC attack under such uncertain environment as the probabilistic MVC attack. Based on the probabilistic MVC attack, we propose two adaptive metrics, and then present an adaptive greedy algorithm for calculating such metrics accurately and efficiently. Finally, we conduct extensive experiments on 20 real datasets. The results show that P2P and co-authorship networks are extremely robust under the MVC attack while both the online social networks and the Email communication networks exhibit vulnerability under the MVC attack. In addition, the results demonstrate the efficiency and effectiveness of the proposed algorithms for computing the proposed metrics.
