What is MQTTS? Secure MQTT Communication for IoT Devices
In IoT systems, devices often communicate using MQTT (Message Queuing Telemetry Transport)—a lightweight and efficient publish/subscribe protocol. However, standard MQTT communication is unencrypted, which makes it vulnerable to eavesdropping and man-in-the-middle attacks. To solve this, we use MQTTS, which is simply MQTT over SSL/TLS encryption. In this article, we’ll explore what MQTTS is, why it’s…
