摘要
在不破坏网络的整体性的前提下,提出threat-CIM方法,给出直接威胁、间接威胁和威胁的定义,在威胁定义的基础上定义防守方各点的条件威胁,解决了边赋权网络节点重要性测度问题;以条件威胁的大小来测量防守方各点的重要性,并进行仿真分析;通过攻守方所占区域的变化,得出防守方的节点重要性也发生相应的变化这一结论;在文章的结尾就攻防双方威胁的关系问题予以解决。
Without destroying network integrity, threat-CIM is put forward and threat, direct threat as well as indirect threat are defined. Based on the definition of threat, conditional threat of defense node is defined, which solves the importance measurement for node within an edge-weighted network. The conditional threat of defense node is used to measure the importance of every node, with simulative analysis conducted. It is concluded that the importance of defense node varies with the changed area occupied by attacker and defender. And the end of the article resolves the threat relation between attacker and defender.
