| As the most crucial communication network for mobile combat forces,Tactical Internet is the basis for the construction of digital forces.Tactical Internet is a collection of tactical radio stations,switch routing equipment,computer software and hardware equipment,it is usually used to ensure the seamless transmission of information such as situational awareness,command,and coordinated operations among various military communication systems.With the continuous development of information and communication technology,cyber warfare and electronic warfare have become the main combat methods in modern warfare.Cyberspace security has become an important strategic resource for the military of various countries to compete.As an important basic platform for network technology research and offensive and defensive exercises,the cyber range has also received extensive attention.There have been some well-established network attack and defense shooting ranges at home and abroad,but most of them are used in general Internet and cannot reflect the characteristics of the Tactical Internet.With the growing size of the Tactical Internet organization and the continuous updating of communication equipment and network offensive and defensive methods.The cyber range based on real-world environments are increasingly unable to meet the needs of offensive and defensive exercises.Therefore,it is of great significance to realize the Tactical Internet network electric offensive and defensive simulation shooting range that adapts to the complex battlefield environment and efficient offensive and defensive exercises.This article has designed and implemented a network simulation range suitable for Tactical Internet offensive and defensive exercises through in-depth research on the organizational structure and security threats of the Tactical Internet.First,on the basis of analyzing the constitutional elements and simulation process of the Tactical Internet system,a method of constructing a simulation model of the Tactical Internet system according to the hierarchical design of protocols,equipment,platforms and networks is proposed,which can flexibly build the Tactical Internet.Secondly,the common offensive and defensive methods of the Tactical Internet are classified according to the protocol level,and the principle analysis,parameter induction and deduction process design of representative offensive and defensive technologies at each level are carried out,and a network attack and defense simulation model suitable for the Tactical Internet is constructed.Then,according to the typical Tactical Internet system and the simulation model of the network and electric power,a simulation system of the Tactical Internet and electric power range is designed and developed based on the OPNET simulation platform.The system is composed of functional modules such as simulation model library,scenario deployment,and simulation verification.Finally,a variety of offensive and defensive exercise scenarios were constructed on the network simulation range with reference to the real military communication network,and the correctness and effectiveness of the network and electrical offense and defense models were experimentally verified.The experimental results show that the network simulation range implemented in this article can meet the needs of offensive and defensive drills on Tactical Internet.In this article,the research and realization of the Tactical Internet network electronic attack and defense simulation range can save the cost of network offensive and defensive exercises,improve the flexibility of the exercise method,and has certain reference significance for the construction of our country’s military network offensive and defensive range. |
