摘要
针对当前地图数据模型难以有效表达网络空间要素复杂关联和动态变化特征的问题,本文首先分析了网络空间地图的概念和特点,将网络空间时空实体作为网络空间地图表达的基本单元;然后结合其特点,提出了从实体层、特征层和变化层建立网络空间时空实体表达模型;最后重点研究了网络空间时空实体动态变化和关系特征的可视化方法,并以典型国家网络安全事件表达为例,进行了可视化技术实现。结果验证了本文提出的表达模型可有效应用于网络空间多维、关联、动态特征的表达,也为后续网络空间地图可视化研究与应用提供了参考。
Aiming at the problem that the current map data model is difficult to effectively represent the complex correlation and dynamic change characteristics of cyberspace elements,this paper analyzes the concepts and characteristics of cyberspace map and cyberspace spatio-temporal entity,and takes cyberspace spatio-temporal entity as the basic unit of cyberspace map representation.Secondly,the cyberspace spatio-temporal entity representation model is proposed to be established at three levels,namely entity layer,feature layer and change layer.Finally,it focuses on the visualization method of dynamic changes and relationship characteristics of cyberspace spatio-temporal entities,and takes typical national cybersecurity events as an example for visualization technology implementation,which verifies that the representation model proposed in this paper can be effectively applied to the representation of multi-dimensional,correlated,and dynamic characteristics of cyberspace,and provides a reference for the subsequent research and application of visualization of cyberspace maps.
