NTNShield: Протоколы CCSDS SDLS, шифрование 3GPP и квантово-стойкие спутниковые группировки

NTNShield разрабатывает высокоскоростные радиационно-стойкие постквантовые шифраторы каналов для неназемных сетей (NTN), защищая оптические межспутниковые линии (OISL) свыше 100 Гбит/с и спутниковую радиосвязь 3GPP.

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)

Защита глобальных спутниковых сетей от космического квантового наблюдения

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.
