NTNTrust: Zero-Trust Space Architecture & Post-Quantum Spacecraft Attestation

NTNTrust standardizes zero-trust cyber-physical security frameworks for satellite constellations, enforcing post-quantum cryptographically signed telemetry, mutual hardware attestation, and anti-tamper enclaves.

NTNTrust Spaceborne Zero-Trust Identity & Attestation Pipeline

Continuous hardware root-of-trust verification across optical inter-satellite mesh links

Central System: Hardware Root-of-Trust (TPM/HSM) - Radiation-hardened physical unclonable function (PUF) core

Network Nodes

Hardware Root-of-Trust (TPM/HSM)
Remote Attestation Engine
ML-KEM / ML-DSA Crypto Core
Constellation Security Operations Center

Architectural Protocol Layers

Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
