耐放射線宇宙機向けHSM＆衛星テレメトリセキュリティ

SpaceHSM Orbital Cryptographic Architecture

Cryptographic Enclave: Space Security Core — Rad-Hard / CCSDS Enclave

Hardware Security Nodes & Co-Processors

• CCSDS SDLS Telecommand Authenticator
• Multi-Gigabit Laser ISL Encryptor
• TID > 100 krad Radiation-Hard Silicon
• Anti-Spoofing Ephemeris Signer
• Autonomous Anti-Tamper Flight Guard

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)
