一种计算机网络关键节点识别方法

A method of key nodes identification on computer network

计算机网络安全作为一个国家在全球性竞争中生存的战略因素,长期以来在不同学科领域都受到了较广泛的关注,而对计算机网络关键节点识别并进行保护可以有效提高计算机网络安全水平。该文基于复杂网络理论,选取网络效率、连接密度、最大连通子图和网络结构熵4个典型的整体性能指标作为评价指标体系,并引入TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)方法给出了计算机网络中关键节点的识别方法,并与其他方法进行比较,结果表明,提出的方法能够准确识别计算机网络关键节点,为有效保护计算机网络安全提供了参考。

As a strategic factor for a country to survive in the global competition,computer network security has long received extensive attention in different disciplines,and the identification and protection of key nodes in computer network can effectively improve the level of computer network security.Selection based on the theory of complex network,the network efficiency,connection density,largest component and the overall performance of the network structure entropy,a total of four typical index as an evaluation index system,and introduced TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)method gives a recognition method of key nodes in computer network,and comparing with other methods,the results show that the proposed method can accurately identify key computer network nodes.It provides a reference for the effective protection of computer network security.
