After the handshake is complete, an encrypted communication between client and server is established and no attacker can eavesdrop any part of the communication. At the core, TLS and SSL are cryptographic protocols which use a handshake mechanism to negotiate various parameters to create a secure connection between the client and the server. Transport Layer Security (TLS) and Secure Sockets Layer (SSL) provide a secure communication channel between a client and a server. Join us as we explore why TLS / SSL is expedient for a secure MQTT solution and talk about best practices for transport encryption with MQTT. In this post, we tackle Transport Encryption with TLS. In the previous post, we looked at authentication in MQTT and authorization in MQTT on the application layer.
