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)

Protegiendo Mallas de Satélites Globales Contra la Vigilancia Cuántica Basada en el Espacio

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
