xBlackBox: Aviation Black Box Protection

The Problem

Flight recorder data (FDR/CVR) stored in single black boxes can be lost in crashes, ocean depths, or deliberately destroyed. Single-point storage is fundamentally inadequate for safety-critical data.

The aviation industry has lost critical flight data in some of its most important investigations. MH370's flight recorders remain unrecovered at the bottom of the ocean. AF447's black boxes took two years to locate. In each case, the investigation was severely hampered by reliance on a single physical device.

Modern aircraft generate terabytes of telemetry data per flight, yet the regulatory framework still depends on crash-survivable memory units designed in the 1960s. Satellite uplink solutions exist but transmit data to a single ground station, creating a new single point of failure.

The Old Way

The PRIVATE.ME Solution

XorIDA splits flight recorder data across independent aviation authorities in real time. Large recordings are automatically chunked. No single authority holds a complete recording.

Flight data is continuously split and distributed via satellite uplink to geographically separated aviation authorities. Each authority receives only a share of the data that individually reveals nothing about the flight parameters or cockpit audio.

Reconstruction requires K-of-N authority cooperation, ensuring that data access follows proper investigative procedures. The automatic chunking system handles recordings of any size, splitting each chunk independently with HMAC verification.

The New Way

How It Works

The flight data protection pipeline streams telemetry from onboard recorders, chunks it for bandwidth efficiency, splits each chunk via XorIDA, and distributes shares to authorities via satellite uplink.

Use Cases

Integration

import { splitRecording, reconstructFlight } from '@private.me/xblackbox';

// Split FDR data across 3 authorities (2 needed)
const shares = await splitRecording(fdrData, authorities, {
  n: 3,
  k: 2,
});

// Distribute via satellite uplink channels
await Promise.all(shares.map((s, i) =>
  uplinkToAuthority(authorities[i], s)
));

// Reconstruct with any 2 authority shares
const flight = await reconstructFlight([
  shares[0], shares[2]
]);

Security Properties

Verifiable Data Protection

Every operation in this ACI produces a verifiable audit trail via xProve. HMAC-chained integrity proofs let auditors confirm that data was split, stored, and reconstructed correctly — without accessing the data itself.

Ship Proofs, Not Source

xBlackbox generates cryptographic proofs of correct execution without exposing proprietary algorithms. Verify integrity using zero-knowledge proofs — no source code required.
