What’s the difference between TLS vs DTLS?

The main difference is DTLS uses UDP and TLS uses TCP. DTLS stands for Datagram Transport Layer Security and is a communications protocol designed to protect data privacy and prevent eavesdropping/tampering. It is based on TLS protocol and used across web browsing, mail, and instant messaging.

Using the DTLS library of wolfSSL, sensor data is protected all the way from the client to the gateway, and then from the gateway on to the broker using standard TLS.
