🔬 Technical Achievements

1. Three Production-Ready Audio Profiles

Profile 1: 16 kHz (WebRTC/Telephony)

  • Sample rate: 16,000 Hz
  • Frame size: 4,096 samples (256 ms)
  • Challenge bits: 32
  • Frequency band: 1,200-4,200 Hz
  • Use case: VoIP, telephony, WebRTC

Profile 2: 44.1 kHz (Consumer Audio)

  • Sample rate: 44,100 Hz
  • Frame size: 8,192 samples (186 ms)
  • Challenge bits: 48
  • Frequency band: 2,000-9,000 Hz
  • Use case: Consumer applications, CD-quality

Profile 3: 48 kHz (High-Fidelity)

  • Sample rate: 48,000 Hz
  • Frame size: 8,192 samples (171 ms)
  • Challenge bits: 64
  • Frequency band: 2,500-12,000 Hz
  • Use case: Studio applications, maximum stealth

2. Security Properties

✅ Replay Resistance: Nonce uniqueness + timestamp window enforcement
✅ Challenge Binding: Watermark deterministically derived from challenge
✅ MAC Unforgeability: HMAC-SHA256 for transcript authentication
✅ Harmonic Collision Avoidance: Rejects bins where 2k_j or 3k_j collide
✅ Fixed-Size Window: Enforces exact N samples for matched filtering

3. Mathematical Verification

Watermark Formula:

s[n] = Σ(j=1 to b) a_j · (-1)^(c_j) · sin(2π k_j · n/N + φ_j)

Matched Filter:

p_j = (2/N) · Σ(n=0 to N-1) y[n] · sin(2π k_j · n/N + φ_j)

Correlation Score:

corr = Σ(j=1 to b) (-1)^(c_j) · p_j

Decision Rule:

ALLOW ⟺ S_crypto(t) = 1 ∧ S_audio(t) = 1
QUARANTINE ⟺ S_crypto(t) = 1 ∧ S_audio(t) = 0
DENY ⟺ S_crypto(t) = 0

🔗 Integration Points

Layer 11 (Triadic Consensus) 

import { DualChannelGate, PROFILE_16K } from './symphonic/audio';
import { TrustManager } from './spaceTor/trust-manager';

class TriadicConsensus {
  private dualChannel: DualChannelGate;
  private trustManager: TrustManager;

  verify(request: Request): 'ALLOW' | 'QUARANTINE' | 'DENY' {
    // 1. Dual-channel consensus
    const dcResult = this.dualChannel.verify({
      AAD: request.AAD,
      payload: request.payload,
      timestamp: request.timestamp,
      nonce: request.nonce,
      tag: request.tag,
      audio: request.audio,
      challenge: request.challenge,
    });

    // 2. Trust scoring (Layer 3)
    const trustScore = this.trustManager.computeTrustScore(request.nodeId, request.trustVector);

    // 3. Triadic consensus
    if (dcResult === 'ALLOW' && trustScore.level === 'HIGH') {
      return 'ALLOW';
    } else if (dcResult === 'DENY' || trustScore.level === 'CRITICAL') {
      return 'DENY';
    } else {
      return 'QUARANTINE';
    }
  }
}

📝 Usage Example 

import * as crypto from 'crypto';
import { DualChannelGate, PROFILE_16K } from '@scbe/aethermoore/symphonic';

// Initialize gate
const K = crypto.randomBytes(32); // Master key
const gate = new DualChannelGate(PROFILE_16K, K, 60); // 60s window

// Server: Generate challenge
const challenge = gate.generateChallenge();
// Send challenge to client...

// Client: Generate watermark and embed in audio
// (client-side implementation)

// Server: Verify request
const result = gate.verify({
  AAD: Buffer.from('metadata'),
  payload: Buffer.from('request data'),
  timestamp: Date.now() / 1000,
  nonce: 'unique-nonce-123',
  tag: hmacTag,
  audio: audioSamples,
  challenge: challenge,
});

console.log(result); // 'ALLOW', 'QUARANTINE', or 'DENY'

🔐 Security Analysis

Threat Model

In Scope:

  • ✅ Replay attacks (stale audio/transcript)
  • ✅ Forgery attacks (fake transcripts)
  • ✅ Challenge prediction (guessing bins)

Out of Scope:

  • ⚠️ Deepfake synthesis (not claimed as defense)
  • ⚠️ Side-channel attacks (timing, power)
  • ⚠️ Physical attacks (mic tampering)

Attack Resistance

Attack Vector Mitigation Effectiveness
Replay Nonce uniqueness + timestamp ✅ Provably secure
Forgery HMAC unforgeability ✅ Cryptographically secure
Challenge prediction HMAC-derived bins ✅ Computationally infeasible
Watermark removal Spread-spectrum embedding ⚠️ Requires empirical validation

🎓 Key Insights from Grok’s Analysis

What’s Novel

✅ Dual-Channel Consensus - Combining crypto transcript + challenge-bound acoustic watermark
✅ Challenge-Bound Watermarking - Deterministic bin selection from HMAC-derived seed
✅ Matched-Filter Verification - Correlation score with challenge-dependent signs

What’s NOT Novel (Prior Art)

  • HMAC-SHA256 (standard crypto)
  • Spread-spectrum watermarking (known technique)
  • Matched filtering (signal processing)
  • Acoustic holography (physics)

Patent Strategy

Focus on:

  • The specific protocol combining two independent channels
  • The deterministic bin selection from challenge
  • The ALLOW/QUARANTINE/DENY decision logic
  • The integration with Layer 11 (Triadic Consensus)

Don’t claim:

  • “Unbreakable crypto” or “deepfake-proof”
  • Voice biometric authentication
  • General audio watermarking
