In this hands-on tutorial, you will learn how to connect securely to an AWS IoT MQTT broker using mutual certificate authentication. An online interactive Lua tutorial includes ready-to-use Lua code, enabling you to connect to your own AWS IoT core instance after signing up for a free AWS account.

TLS also supports mutual authentication, where the brokers use certificates to verify the clients’ identities. If this all sounds Greek to you, check out my previous article, A Gentle Introduction to Asymmetric Encryption, which explains the core principles behind X.509 certificate authentication.
