Data security risks and countermeasures under the space-ground integrated computing network

随着星载算力和星间通信技术的不断发展,天地一体化算网融合技术通过高效协同地面和星上的数据、通信和计算等资源,有望克服目前因感知、通信和计算各自优化所带来的大量时延敏感任务响应延迟等问题。天地一体化算网融合的未来系统,作为广域信息服务的一体化网络系统,涉及大量的数据交互。然而,其信道开放、网络拓扑高度时变等特性导致在数据感知、存储、传输、智能处理和服务环节中暴露了大量的攻击面,使得遥感等高价值数据易成为攻击对象,进而威胁数据安全和用户隐私。针对上述问题,归纳了天地一体化算网融合未来架构、关键技术和应用。深入分析了这一背景下数据的关键特征以及面临的数据安全风险。进一步探讨了一系列可能的风险防范机制,并对未来的数据安全研究方向进行了展望。

As the development of onboard computing power and inter-satellite communication technology,the space-ground inte-grated computing network is expected to solve the issues of response delay caused by optimizing sensing,communication,and comput-ing separately in a multitude of time-sensitive tasks by using the distributed data,onboard computing and communication resources col-laboratively.The forthcoming space-ground integrated computing network serving as an integrated network system for providing wide-area information services,involves a significant amount of data interaction.However,its characteristics such as open channels and high-ly dynamic network topology expose a broad range of vulnerabilities in data sensing,storage,transmission,intelligent processing and service,making the high-value data like remote sensing susceptible to attacks,and thereby threatening the data security and user privacy.To this end,the future technical architecture,key technologies and applications of the space-ground integrated computing network were summarized.Then,the key features and the security issues of data were deeply analyzed.Next,a series of possible countermeasures were further discussed,and the future research directions of data security were prospected.
