Quantum key distribution in the distributed TT&C network

With the development of the technology in the Distributed TTC(track,telemetry and control) Network,the Distributed TTC is faced with the problem of information security.Through analysis and study of all kinds of information encryption,considering of the classic encryption technology that has the deficiency of no guarantee on the absolute security on information,quantum mechanics-based quantum key distribution technology was used to ensure the TTC of the transmission of information's absolutely safe.Based on the combination of "absolutely confidential" method and the Distributed TTC Network technology,this paper put forward a combining model of quantum key communications and the Distributed TTC Network.
