Architectural Layers & Silicon Defenses

Layer 1: Radiation-Hardened Semiconductor Die (Silicon-on-Insulator (SOI) / Rad-Hard CMOS): Tolerating Total Ionizing Dose > 100 krad(Si) and linear energy transfer (LET > 75 MeV·cm²/mg) with zero latchup.
Layer 2: CCSDS Space Data Link Security (SDLS) Core (Hardware AES-GCM-256 / Extended Procedures): Encrypting Telemetry (TM) and authenticating Telecommand (TC) frames according to CCSDS 355.0-B-1.
Layer 3: Multi-Gigabit Optical Cross-Link Pipeline (Co-Packaged Optics / Multi-Gigabit AES ASIC): Encrypting high-speed laser cross-links (OISL) between constellation satellites at 10 Gbps to 40 Gbps.
Layer 4: Spacecraft On-Board Computer & Avionics Bus (SpaceWire (ECSS-E-50-12C) / MIL-STD-1553B): Interfacing with spacecraft flight computers, attitude control systems, and sensor payload instruments.

Cryptographic Telemetry & Compliance: > 100 krad (Total Ionizing Dose (TID) Tolerance) | Zero-SEFI (Single Event Latchup Immunity) | 10-40 Gbps (Optical ISL Line-Rate Encryption) | CCSDS SDLS (Space Data Standard Certified)

Racines de confiance matérielles pour l'environnement orbital hostile

Commercial satellite megaconstellations and military space assets operate in high-radiation orbital environments vulnerable to electronic jamming, ground-station spoofing, and physical cosmic ray bit-flips. SpaceHSM delivers radiation-hardened silicon enclaves that execute CCSDS Space Data Link Security protocols, protecting satellite control systems against hostile ground injection.

Core Engineering Areas

CCSDS Space Data Link Security (SDLS) — Engineering cryptographic frame authentication and encryption pipelines for satellite telecommand and telemetry links.
Radiation-Hardened Silicon & SEE Immunity — Engineering silicon architectures immune to Single Event Upsets (SEU), Single Event Latchup (SEL), and Total Ionizing Dose (TID).
Optical Inter-Satellite Link (OISL) Encryption — Securing optical inter-satellite mesh networks operating at 10 to 40 Gbps across orbital planes.
