NTNShield: CCSDS SDLS Protokolle, 3GPP Satelliten-Verschlüsselung & quantensichere Konstellationen

NTNShield entwickelt strahlungsgehärtete Hochgeschwindigkeits-Post-Quanten-Link-Verschlüssler für nicht-terrestrische Netzwerke (NTN), die optische Intersatellitenverbindungen (OISL) mit über 100 Gbit/s und 3GPP-Satellitenfunkzugänge vor Quantenangreifern schützen.

Architectural Layers & Protocols

Optical Inter-Satellite Link (OISL) Physical Layer (Coherent 1550nm Laser Terminals with Fine Steering Mirrors): Transmitting terabits of inter-satellite mesh traffic across thousands of kilometers in vacuum
CCSDS Space Data Link Security (SDLS) Post-Quantum Extension (Frame-Level Encryption & Integrity Protection for Telemetry and Telecommand): Securing spacecraft command receivers (TC) and telemetry downlinks (TM) against replay and spoofing
Doppler-Resilient Dynamic Session Re-Keying (Ephemeris-Driven Fast Ephemeral Key Encapsulation): Negotiating fresh session keys during rapid 7.5 km/s orbital passes between satellite and teleport
Radiation-Hardened Space Silicon & Cryptographic Boundary (Space-Grade Rad-Hard FPGAs (Xilinx Virtex-5QV / RTG4 / PolarFire)): Executing constant-time lattice polynomial reduction without single-event latchup or functional interrupt

Key Metrics: 100 Gbps+ (Optical Link Line-Rate) | CCSDS SDLS (Space Data Link Standard) | 100 krad (Total Ionizing Dose (TID)) | <5 µs (Hardware Frame Latency)

Schutz globaler Satellitennetze vor weltraumgestützter Quantenüberwachung

Satellites broadcast radio signals across continental footprints where adversaries can passively record vast data streams without detection. NTNShield deploys high-throughput lattice encryption directly aboard low Earth orbit spacecraft.

Core Engineering Areas
