Design and Application Prospects of Zero-Trust Architecture for Near-Space Networks
The unique position of near space makes its network,centered around various near-space vehicles,a critical component of the integrated air-space-ground network.The near-space network transmits,processes,and stores a large amount of high-value,sensitive data,making its security protection crucial.This paper outlines the composition of the near-space network,its connections with other nodes,and potential network applications.Based on an analysis of its vulnerabilities,we identify security requirements in areas such as identity authentication,data security,network availability,and vehicle control.The zero-trust architecture,an important trend in network security,is scientifically and reasonably extended to near-space network protection.Accordingly,we propose a zero-trust architecture for near-space networks,discussing in detail its overall architecture,evaluation model,access control model,and policy definition framework.Furthermore,we address challenges such as the significant initial workload of information processing,the high complexity of policy formulation and maintenance,and the deployment difficulty due to unclear network architecture.Furthermore,we explore the application value of new technologies,development concepts,and implementation points in deploying the zero-trust architecture for near-space networks.
