Security of connected devices is of paramount concern. There are several possible ways to make the devices secure. One of the most essential and widely used options is to use end to end encryption. The widely used Transport Layer Security (TLS) version 1.2 is the latest standard used on web for secure connections including banking. There are very few micro-controller based solutions that implement TLS 1.2 due to lack of resources. ESP32 is one of the most affordable options out there. So let’s look at securely connecting Hornbill ESP32 Dev board to Amazon web services (AWS) IOT.
We will start with configuring AWS account, setting up the thing, generating the security certificates, testing with a MQTT desktop client and then communicating with the hardware.
You’ll need an ESP32 Dev board to accomplish this. We are running a campaign for the most affordable and feature rich ESP32 dev tools called Hornbill. Get one from the campaign here:
