Networked TT&C for Mega Satellite Constellations:A Security Perspective
文献摘要：
Satellite constellations are promising in enabling the global Internet. However, the increasing constellation size also complicates tracking, telemetry and command (TT&C) systems. Traditional ground-based and space-based approaches have encountered significant obstacles due to, e.g., the limited satellite visible arc and long transmission delay. Consider-ing the fast development of intersatellite communica-tions, synergy among multiple connected satellites can be exploited to facilitate TT&C system designs. This leads to networked TT&C, which requires much less predeployed infrastructures and even performs better than traditional TT&C systems. In this paper, we elaborate system characteristics of networked TT&C compared with traditional ground-based and space-based TT&C, and propose the unique security chal-lenges and opportunities for networked TT&C, which includes secure routing and trust mechanisms. Fur-thermore, since networked TT&C is a novel scenario with few relevant researches, we first investigate the current researches on secure routing and trust mecha-nisms for traditional terrestrial and satellite networks, and then accordingly deliver our security perspectives considering the system characteristics and security re-quirements of networked TT&C.
