Architectural Layers & Protocols

Airborne Databus Isolation & Security (ARINC 664 Part 7 (AFDX) & MIL-STD-1553 Cryptographic Overlay): Injecting post-quantum authentication into deterministic avionics Ethernet virtual links
Next-Gen ADS-B Quantum Authentication (Lightweight Elliptic Curve & Lattice Signature Combiners): Preventing ghost aircraft injection and trajectory spoofing in Air Traffic Management (ATM)
Cockpit Voice & Controller-Pilot Datalink (CPDLC) (Post-Quantum Secure Voice and Text Telemetry over SATCOM): Shielding critical air-to-ground air traffic control instructions from eavesdropping and spoofing
Airborne Flight Hardware Root of Trust (DO-254 Level A FPGA and Radiation-Tolerant Cryptographic Coprocessors): Isolating flight control cryptographic keys within DO-160G environmentally certified boundaries

Key Metrics: DAL-A (Target DO-178C Safety Level) | DO-326A (Airworthiness Security Framework) | <10 ms (Flight Control Telemetry Latency) | Zero-Spoof (Navigation Integrity Guarantee)

Les plateformes aéroportées font face à des fenêtres de vulnérabilité quantique de 30 ans

Commercial airliners and military aircraft certified today will remain active for decades. Legacy airborne databuses (ARINC 429, MIL-STD-1553, AFDX) were designed without cryptographic authentication, leaving avionics exposed to spoofing and quantum-enabled signal synthesis.

Core Engineering Areas

DO-326A Airworthiness Compliance — Airborne security risk assessment, threat condition assignment, and formal certification evidence.
Securing ARINC 664 AFDX — Maintaining microsecond determinism and zero packet jitter on critical flight control virtual links.
Authenticating ADS-B Signals — Preventing GPS spoofing and ghost track injection in military and civil airspace.
