AvionicsSecurity DO-326A Defense Architecture
Airworthiness Security Domain Separation, Secure Gateway Firewalls & Cryptographic HSM
Central System: Secure Airborne Gateway (SAG) - Cryptographic Domain Boundary Firewall
Aviation Architecture Nodes
- Aircraft Control Domain (ACD)
- Airline Information Services (AISD)
- Passenger Information Domain (PIESD)
- Hardware Security Module (HSM)
- Airborne Intrusion Detection (IDS)
Architectural Layers & Protocol Stacks
- Physical Domain Separation & Data Diodes (Hardware Unidirectional Data Diodes / Galvanic Domain Isolation): Hardware-enforced unidirectional optical data diodes preventing any packet propagation from passenger Wi-Fi into flight control computers.
- Airborne Cryptographic Root of Trust (FIPS 140-3 Level 3 / ARINC 835 Cryptographic Services): Dedicated tamper-resistant Hardware Security Modules (HSMs) managing cryptographic keys, secure boot validation, and signed firmware verification.
- Deterministic Avionics Bus Intrusion Detection (Airborne IDS Engine / Statistical Message Frequency Analyzer): Real-time deep packet inspection of ARINC 429, AFDX, and CAN bus frames, detecting anomalous timing jitter and spoofed command labels.
- Secure Ground-Air Software Loading (ARINC 645-1 Common Digital Certificate Profile / ARINC 615A-3): Encrypted and authenticated Field Loadable Software (FLS) pipeline compliant with ARINC 615A and ARINC 645 standards.
Flight Telemetry Metrics: 100% (DO-326A / ED-202A Regulatory Coverage) | < 10 µs (Bus Anomaly Intrusion Alert Latency) | FIPS 140-3 (Hardware Cryptographic Security Level) | 0 routes (Data Diode Reverse Flow Vulnerabilities)
Défendre l'avion connecté moderne contre les cybermenaces
The transition to e-Enabled aircraft, wireless ground operations, and connected passenger cabins has opened avionics to remote attack vectors. AvionicsSecurity provides the certified security architecture to isolate critical fly-by-wire flight domains, establish hardware-enforced roots of trust, and detect bus intrusions in real time.
Core Engineering Areas
- DO-326A Process — Security risk assessment, threat modeling, and security verification for type certification of modern aircraft.
- Avionics HSMs — Establishing unassailable cryptographic roots of trust in avionics silicon to verify every line of executed machine code.
- Bus Intrusion Detection — Sniffing out unauthorized packets, timing discrepancies, and rogue bus masters in hard deterministic aviation networks.
