MQTT-with-TLS

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

For further notes and links, see my Dust-Notes repository.

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)
