Abstract
As a large heterogeneous information infrastructure, space terrestrial coinformation network provides a reliable and effective services for all types of space-based users, aviation users, marine users and land-based users through satellite networks. However, the precious computing and storage resources of satellite nodes during the service life is not fully exploited, and the enormous potential of the space information network (SIN) needs to be tapped to provide personalized services to end users. In this paper, to improve the utilization of satellite node resources and better meet the real-time requirements of compute-intensive and delay-sensitive users, we propose the SIN fog service. SIN fog service is an extension of fog service paradigm. The visionary concept is to integrate the computing power of satellite network edge nodes, enabling a wide range of benefits, including enhanced computing power, decreased bandwidth, reduced latency and without the need to lay complex and expensive ground networks, which can be widely developed in location navigation, environmental detection, traffic management, anti-terrorism, etc. We present the architecture and a potential use case of the SIN fog service. Then we discuss several related key security and challenges and finally the anti-quantum and efficient mutual-authentication protocol is introduced.

Summary
Space information network (SIN) is a globally heterogeneous network that includes satellite backbones, high-altitude platforms, aircraft, terrestrial control stations, and ground communications equipment. With the rapid development of satellite communication and computing power in recent years, SIN has been able to provide a globally reliable communication network for communication equipment via satellite networks [1]. The delay from terrestrial communication equipment to its visible Low earth orbit (LEO) satellites can be reduced to 1 to 4 ms [2], which can meet the user’s quality of service (QoS) requirement. Fog service is the extension of cloud paradigm, which solves the above application requirements by integrating the resources of the network edge nodes to greatly reduce the delay.
