通过分析等级化信息系统安全应用支撑平台的设计结构,针对不同等级间信息系统的互联会导致许多额外风险等问题,将可信网络连接(TNC)思想引入到定级系统应用平台的互联中,提出了一种面向等级保护的多级安全域间可信互联方法,设计了域间多级可信网络互联的框架,说明了架构运行的控制流程,并将其应用到具体的等级化信息平台的互联中,给出了实际互联方案,并对互联可信性进行了分析。为保障等级化安全应用平台跨域互联的可信性和安全性,特别是减少不同等级应用平台互联带来的额外风险,提供了有效的互联技术框架和方法。
By analyzing the design structure of security application support platform of hierarchical information system, the interconnection of information systems between different levels will lead to many extra risks and other issues. The idea of trusted network connection (TNC) is introduced into the interconnection of application platform of rating system, This paper proposes a class-level trusted multi-level secure inter-domain trusted interconnection method, designs the framework of inter-domain multi-level trusted network interconnection, explains the control flow of architecture operation and applies it to the specific hierarchical information platform Of the Internet, gives the actual Internet program, and the credibility of the Internet were analyzed. In order to ensure the reliability and security of cross-domain interconnection of hierarchical security application platforms, and in particular to reduce the additional risks brought by the interconnection of different levels of application platforms, an effective interconnection technology framework and method are provided.
