Below are key best practices:
  1. End-to-End Encryption: Ensure all data exchanged between peers is encrypted, using protocols like TLS or custom end-to-end encryption schemes.
  2. Mutual Authentication: Implement strong authentication using OAuth, JWT, or cryptographic handshakes to verify both peers.
  3. Secure Transport Layers: Use secure transports such as WebSockets or Bluetooth LE with encrypted channels to prevent eavesdropping.
  4. Key Management: Regularly rotate encryption keys to prevent compromise over time.
