Guides and code examples for configuring MQTT on IoT with TLS, and other security features.

What this repository covers

I've been working on creating secure IoT devices, with the Arduino Nano 33 IoT micro-control unit. My aim is to

• spawn VerneMQTT brokers to handle and deliver messages
• use NGiNX as a load balancer for the brokers
• configure NGiNX for TLS TCP streams
• use the IoT device to send MQTT packets via TLS over WiFi

This repository will act as an overview, and eventually a guide, as to a possible implementation of this goal, first on a privately owned server, and later over AWS.

Organisation

As this project is a work in progress, I am unsure how I will organise the final overview. Most of my notes will be included in my Dust-Notes/mq-mqtt and Dust-Notes/arduino repository, however I will include explicit code examples both in this repository, and in my own Ego and the Id-IoT project.

For relevant notes, see here:

• minimal MQTT protocol overview here
• NGiNX as a load balancer (with Docker) here
• VerneMQ cluster (with Docker) (TODO)
• Configuring SSL/TLS on NGiNX (TODO)
• Uploading CA certificates and onto Arduino firmware here
• Configuring the ATECC608a secure chip here
• Testing the communication system is secure (TODO)
