Satellite-Ground Integrated Quantum Secure Communication Pilot Project for a Border Defense Outpost

Satellite-Ground Integrated Quantum Secure Communication Pilot Project for a Border Defense Outpost

Background

The embassy is located in a country with a complex cybersecurity environment. Traditional communication methods carry a serious risk of eavesdropping, and the local terrestrial network is unstable with frequent outages, making it impossible to guarantee the security and continuity of classified communications.

Solutions

Deployed one mobile quantum satellite ground station as a backup and supplement to the terrestrial network.

Equipped customized quantum-secure mobile terminals and encryption modules for office computers.

Connected to the Guoxing Space Quantum Cloud Platform to enable end-to-end quantum key distribution with the headquarters in China.

Deployed a cross-border quantum security gateway to enable intelligent switching between the terrestrial and satellite networks.

Results

Achieved end-to-end quantum-secure encryption for classified documents and voice/video conferences, completely eliminating the risk of communication eavesdropping.

Automatically switches to the satellite communication link when the terrestrial network is interrupted, ensuring communication continuity.

Meets the cryptography regulatory requirements of both China and the host country, and successfully passed the security inspections of both sides.

The system operates stably with no security incidents, earning high praise from the embassy.
