Crash-Survivable Flight Data Recorders: Encrypting the 'Black Box' with Quantum Resilience

Engineering tamper-evident, privacy-preserving cryptographic architectures for Cockpit Voice Recorders (CVR) and Flight Data Recorders (FDR).

Balancing Accident Investigation Access and Pilot Privacy

Cockpit Voice Recorders record ambient cockpit audio and crew communications. Pilot associations and international labor standards demand that audio recordings remain strictly confidential, accessible only by accredited national safety investigation boards (such as the NTSB or BEA) following an accident.

Multi-Key Threshold Cryptography for Accident Investigations

AvionicsVault encrypts flight recorder storage using a multi-party threshold post-quantum encryption scheme. Decrypting the crash-survivable memory unit requires the simultaneous mathematical authorization of the airline, the pilot representative association, and the accredited government accident investigator.

Physical Hardening Under Extreme Impact and Underwater Submersion

Packaging encryption keys and key derivation hardware inside armored stainless steel canisters tested to withstand 3,400g impacts, 1,100°C kerosene fire for one hour, and deep-ocean hydrostatic pressure at 20,000 feet.
