Use Cases Satellites as range extenders for end-to-end QKD networks: An ultra-secure defense network combining terrestrial and satellite QKD with a “flying node” for long distance. It implements hybrid protocols (QKD/PQC) and multi-user communications (QCKA) through VPN tunnels. The entire system is validated with advanced simulators (DSS-Sim, QKDNetSim) in the QuantumLab to shield critical infrastructures against quantum threats. Quantum-secured satellite networks: Establishes ultra-secure satellite communications by protecting the control channel (TT&C) using QKD (Quantum Key Distribution). It combines radio-frequency (RF) and optical signals with improved pointing systems (PAT) to provide a robust hybrid connection. It uses post-quantum cryptography (PQC) specifically for user and device authentication. The entire system is managed via a KMS (Key Management System) compliant with the ETSI-014 standard. Physical and algorithmic security are integrated to ensure the integrity of space infrastructures.
