xNuke: Nuclear Facility Monitoring

The Problem

Nuclear sensor data integrity relies on trust in single monitoring agencies. A compromised or politically pressured agency can suppress safety alerts, falsify readings, or delay critical warnings.

The International Atomic Energy Agency (IAEA) and national regulators depend on sensor networks that report through single organizational channels. Reactor temperature, radiation levels, coolant flow rates, and containment pressure readings all pass through a single chain of custody before reaching decision-makers.

This architecture has a fundamental weakness: a compromised monitoring agency — whether through state pressure, insider threat, or cyberattack — can alter readings to mask dangerous conditions. The Fukushima and Chernobyl incidents demonstrated that institutional trust in monitoring data is insufficient when lives are at stake.

The Old Way

The PRIVATE.ME Solution

XorIDA splits every sensor reading across independent international agencies. Threshold reconstruction guarantees that no single agency — regardless of political pressure — can fabricate a valid reading.

Each sensor reading is split into N shares using XorIDA threshold sharing. Shares are distributed to independent, geographically diverse agencies — IAEA, national regulators, and independent watchdogs. Any K of N shares reconstruct the original reading. Fewer than K shares reveal nothing.

To falsify a reading, an adversary would need to simultaneously compromise K independent agencies across multiple jurisdictions — a vastly harder attack than compromising a single organization. Every share carries HMAC-SHA256 integrity verification, making even single-bit tampering detectable.

The New Way

How It Works

A four-stage pipeline: sensor ingestion, XorIDA split with typed integrity metadata, multi-agency distribution, and HMAC-verified threshold reconstruction.

Use Cases

Integration

import { splitReading, verifyIntegrity } from '@private.me/xnuke';

// Split sensor reading across 3 agencies (2-of-3)
const shares = await splitReading(
  sensorReading,
  ['iaea', 'national-regulator', 'independent-watchdog'],
  { n: 3, k: 2 }
);

// Verify integrity at reconstruction point
const result = await verifyIntegrity(collectedShares);
if (result.ok) {
  // result.value contains the verified sensor reading
  processReading(result.value);
}

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

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