    Position and Time Augment System Security Management Technology for SGIN Based on Consortium Blockchain


    Global Satellite Navigation System (GNSS) can provide accurate time and space information for Space-Ground Integrated Network (SGIN) to support the application in various fields. However, GNSS has inherent vulnerability and cannot provide continuous and reliable positioning and timing services for SGIN users. The quasi-GNSS augment system (QGAS) is used to provide positioning and timing enhancement services for SGIN. QGAS distributes over a wide area, and the heterogeneity of the network poses a significant risk to the security management of the system. The traditional centralized network security technology is not suitable for QGAS. In view of the network spoofing threat of QGAS, a novel security management technology based on consortium blockchain for QGAS is proposed. The architecture and the workflow of the system are given. Security analysis show that the proposed framework can be used as an efficient way to ensure the reliability of PT information, supporting QGAS as a supplement and backup to GNSS. Together, they can provide SGIN with accurate time and space information
