## Neural Interface Support

```json
{
  "neuralInterface": {
    "enabled": false,
    "supported": true,
    "capabilities": {
      "thoughtControl": "experimental",
      "emotionDetection": "beta",
      "directInput": "alpha"
    },
    "privacy": {
      "dataCollection": "opt-in",
      "encryption": "quantum-resistant",
      "localProcessing": true
    }
  }
}
```

## Quantum-Resistant Cryptography

```json
{
  "security": {
    "encryption": {
      "algorithm": "CRYSTALS-Kyber",
      "keySize": 3072,
      "quantumResistant": true
    },
    "signatures": {
      "algorithm": "CRYSTALS-Dilithium",
      "quantumResistant": true
    }
  }
}
```
