Abstract

Abstract: 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.

Key words: cyberspace map, cyberspace spatio-temporal entity, representation model, dynamic change, relational feature, visual representation
