Cross-border classified official documents, diplomatic telegrams, and voice & video conferences carry high risks of eavesdropping and cracking, and traditional encryption systems face threats of decryption by quantum computing.
In regions where some Chinese diplomatic missions are located, terrestrial networks suffer from instability, limited bandwidth and even outage risks, making it impossible to guarantee communication continuity.
It is required to comply with password regulatory requirements of both China and host countries simultaneously, which brings great difficulties in cross-border compliance adaptation.
Office terminals and mobile devices are vulnerable to implantation of malicious programs, with risks of data leakage and device hijacking.
Adopts a full-link protection architecture of quantum satellite constellation + space quantum cloud + customized terminals + chip-level root of trust
Relying on the first-phase globally covered quantum constellation, it provides all-coverage satellite quantum secure communication services for diplomatic missions worldwide, serving as a backup and supplement to terrestrial networks.
Deploy the space quantum cloud key scheduling system and PKI services to realize end-to-end quantum key distribution and identity authentication between diplomatic missions worldwide and domestic headquarters.
Deploy cross-border quantum security gateways to achieve seamless switching between terrestrial fiber links and satellite links, ensuring communication continuity.
Equip diplomatic missions with customized quantum-secure mobile terminals, encryption modules for office computers, and quantum-secure USB security tokens to build a robust line of defense at the endpoint level.
All core devices are embedded with self-developed quantum security chips to build an immutable hardware root of trust.
Adopt the one-time pad encryption mode. Official documents are encrypted throughout transmission, and cannot be decrypted even if intercepted.
It supports real-time quantum encryption for high-definition voice and video conferences to secure meeting content.
Bidirectional trusted authentication between devices and users is implemented based on the hardware root of trust to block access by unauthorized devices.
It realizes trusted boot of terminals, firmware anti-tampering, full-disk encryption of hard drives, and terminal behavior auditing.
When terrestrial network faults occur, the system automatically switches to the satellite communication link to maintain uninterrupted communications.
Real-time audit and log retention are performed for all encryption operations, key usage and communication behaviors to meet compliance requirements.
Dual Compliance Assurance:
Adopt the "National Cryptography + PQC" dual-algorithm system to meet password regulatory requirements of both China and host countries.
Global Full Coverage:
Free from constraints of terrestrial networks, it can guarantee communications even in regions with underdeveloped network infrastructure.
Zero-Perception Upgrade:
No modification to the existing IT architecture of diplomatic missions, enabling smooth integration of quantum security capabilities.
Highest Security Level:
Chip-level hardware encryption plus quantum key distribution achieves zero data leakage under unauthorized access.
