卫星移动通信系统安全防护半实物仿真研究

Semi-physical Simulation of Security Assurance for Satellite Mobile Communication System

为了更深入透彻地建立卫星移动通信系统安全防护总体技术框架,贯彻实现安全防护系统与通信系统“同规划、同设计、同建设”的目标,需要在卫星移动通信系统规划设计之初建立一套与其相配套的安全防护半实物平台。通过该平台实现对卫星移动通信星型网络结构的简单模拟,体现用户入网和通信呼叫情况下的信息安全防护流程,重点验证需要解决的密钥管理、用户认证等关键技术,为卫星移动通信系统的大规模仿真和后续建设提供数据参考。

In order to establish an overall technical framework for the security protection of satellite mobile communication system to an in-depth level and implement synchronized planning,designing and constructing of the security protection system and the communication system,it is necessary to establish a set of semi-physical platforms for security protection at the beginning of.satellite mobile communication system planing and design.Through this platform,a simple simulation of the satellite mobile communication star network structure is realized,which reflects the information security protection process in the case of users accessing the network and communication calls.It focuses on verifying key technologies such as key management and user authentication that need to be resolved,thus providing data references for large-scale simulation and subsequent construction of satellite mobile communication systems.
