Alien Meshtastic Network

Meshtastic Private MQTT Networks and Encryption

Meshtastic is an open-source, off-grid mesh networking protocol utilizing low-power LoRa radios for resilient, long-range communication without relying on traditional cellular or internet infrastructure. In high-stakes operations, our private MQTT networks extend this capability globally while maintaining uncompromising security.

Private MQTT Networks

Our setup employs dedicated private MQTT brokers to bridge disparate Meshtastic meshes over the internet. Unlike public servers, private brokers enforce custom access controls (ACLs) and eliminate zero-hop limitations, enabling seamless message propagation across remote nodes. Gateway devices—such as ruggedized handhelds or fixed relays—connect local LoRa networks to the broker via Wi-Fi or Ethernet, ensuring redundancy in contested environments. This architecture supports integrations with tactical systems like Home Assistant or Node-RED for automated alerts and telemetry routing.

Key configurations include:

• Root Topic Separation: Isolated topics (e.g., msh/private/alien) prevent cross-network leakage.
• Client Proxy: Mobile gateways proxy traffic via phone hotspots for on-the-move bridging.
• Map Reporting: Configurable position precision and intervals for operational awareness without compromising OPSEC.

Encryption Protocols

Security is paramount. All channel communications use AES-256 encryption with custom Pre-Shared Keys (PSKs) generated via secure random methods—never default or simple keys. Primary channels encrypt messages, positions, and telemetry broadcasts, rendering them indecipherable to unauthorized listeners.

Advanced features include:

• Direct Messages (DMs): Protected by Public Key Cryptography (PKC) for end-to-end confidentiality and sender authentication via digital signatures.
• Admin Controls: Enhanced AEAD (Authenticated Encryption with Associated Data) for integrity-checked commands, preventing tampering or spoofing.
• MQTT TLS: End-to-end TLS secures broker connections; payloads can be JSON-encoded for integration while remaining encrypted at the application layer.
• Message Signing: HMAC over content and PSK ensures non-repudiation and detects modifications.

This military-spec implementation guards against passive eavesdropping, active attacks, and known-plaintext exploits, providing a robust foundation for classified mesh operations.
