Combining mathematical lattice security with physical-layer quantum key distribution to guarantee forward secrecy even in event of mathematical cryptanalysis breakthroughs.
The 6G PQC gateway derives the master session key by XORing an ETSI GS QKD 014 one-time pad key with a shared secret negotiated via FIPS 203 ML-KEM. Compromising either mathematical assumptions or physical fiber taps reveals zero information regarding the plaintext session traffic.
In accordance with NIST and BSI migration mandates, the gateway architecture allows network operators to dynamically adjust algorithm parameters (ML-KEM-512/768/1024 or Falcon-512) via SDN policy without taking base station sectors offline.
