Central System: Space Shield Core - Orbital Encryptor

Cryptographic Nodes

  • 100G Laser ISL
  • Q/V Feeder Link
  • CCSDS SDLS PQC
  • Doppler Sync
  • Rad-Hard FPGA

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)

保护全球卫星网络免受基于太空的量子监视

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.
