This paper aims to present an evaluation of targeted attack sequences based on a new set of power traffic centrality measures according to the vulnerability prediction measure (VPM) approach. A framework for evaluation of attack proposed in previous work is applied using three fault strategies: remove most central element first (RMCEF), iterated most central element first, and iterated electrical most damaging element first (IMDEF). For attacks on nodes, the reliability of the IMDEF strategy is confirmed, as it was the most predictive in terms of the VPM. Nevertheless, in attacks performed on links, the IMDEF does not always represents the most harmful attack. Regarding the new centralities, the Katz centrality consistently presented high values of VPM for attacks on nodes and links, with results that are comparable to degree and eigenvector centralities. In terms of execution times, the percolation centrality is not recommended, as it presented the highest execution times. The RMCEF strategy with degree, eigenvector and Katz centralities is a good estimation of the most harmful attack sequences on nodes and links with a shorter execution time than the IMDEF.

基于一组新的中心点的电力系统最有害恶意攻击评估

本文旨在根据脆弱性预测量度(VPM)方法,基于一组新的电力业务集中度量度,对有针对性的攻击序列进行评估。以前的工作中提出的评估攻击的框架使用了三种故障策略:首先去除最中心的元素(RMCEF),首先去除最中心的元素,然后迭代对电子最有害的元素(IMDEF)。对于节点攻击,IMDEF策略的可靠性得到了确认,因为就VPM而言,它是最具预测性的。但是,在对链接执行的攻击中,IMDEF并不总是代表最有害的攻击。关于新的中心性,Katz中心性始终为攻击节点和链接提供了很高的VPM值,其结果可与度和特征向量中心性相媲美。就执行时间而言,不建议使用渗滤集中度,因为它代表了最高的执行时间。具有程度,特征向量和Katz中心性的RMCEF策略可以很好地估计节点和链接上最有害的攻击序列,并且执行时间比IMDEF短。
