Improving Robustness Against the Coordinated Attack by Removing Crashed Hub Nodes in Complex Network

Free registration required

Executive Summary

Recently, several distributed attacks based on local information have been emerged threating network security. The coordinated attack is one of the most destructive attacks, with an important property to identify the next-step target through coordinating all crashed nodes. It has been ignored in most of existing researches that the crashed nodes network size will become larger and larger along with the coordinated attack, which makes the coordinated attack crash each node in the same time virtually impossible. In this paper, the authors propose R.C.H strategy, which removes a fraction of crashed hub nodes to improve network robustness against the coordinated attack.
