In this paper, we deal with the deployment of Post-Quantum Cryptography (PQC) in Internet of Things (IoT). Concretely, we focus on the MQTT (Message Queuing Telemetry Transport) protocol that is widely used in IoT services. The paper presents our novel quantum-resistant security proposal for the MQTT protocol that supports secure broadcast. Our solution omits using TLS with the handshake causing delay and is suitable for sending irregular short messages. Finally, we show how our solution can practically affect concrete use cases by the performance results of the proposed solution.
