In view of the shortcomings of the CCSDS-TC protocol key update mechanism, this paper proposes a satellite-ground key update scheme suitable for space communication. This article analyzes the encryption and authentication methods of the CCSDS-TC protocol, builds a satellite communication protocol simulation platform on OPNET, and implements the proposed satellite-ground key update scheme, encryption and authentication methods. The simulation test of the dynamic update of satellite-ground key and the simulation results of data security transmission denote that the proposed satellite-ground key update scheme in this paper has good security, scalability and low resource consumption, and can provide a secret key parameter which reveals important practical value.
