摘要
随着航空航天技术的发展,利用卫星互联网广覆盖、高带宽和低时延的特性,将地面网络向空间维度扩展成为构建未来网络的新方向。同时,多样性的应用请求及复杂的空间环境特点对星地融合网络(Satellite Terrestrial Integrated Network,STIN)的安全问题提出了新的挑战。为了满足STIN体系架构安全的需求,提出了一种基于软件定义的STIN内生安全系统架构。利用软件定义技术及网络虚拟化技术,根据安全即服务的设计理念,将安全接入认证及安全路由传输等安全运行机制一体化考虑,以提高整个网络架构的灵活性及可靠性。
Aerospace technology is progressing rapidly.And satellite Internet provides many benefitting characteristics,such as wide coverage,high bandwidth and low delay.Now the expansion of terrestrial network to space dimension has become a new direction to construct future network.Meanwhile,the diversity of application requirements and the characteristics of complex space environment bring new challenges to the security integration of satellite-terrestrial network.In order to meet the demands of secure endogenous architecture of satellite-terrestrial integrated network(STIN),we propose an architecture with secure endogenous of software defined satellite-terrestrial integrated network.In this architecture,a concept that security is a service is introduced,and software defined technology and network virtualization technology are used to realize the integration of network cyber security with scheme of network access,routing and transmission.Therefore,the flexibility and reliability of this architecture can be improved.
