Message queuing telemetry transport-secure connection: a power-efficient secure communication

Trust must be established among the internet of things (IoT) devices to ensure successful communication. The key to this trust lies in security enhancements in all IoT connectivity, enabling the exchange of vast amounts of data but keeping in check their power consumption which is a very high constraint when dealing with battery-operated IoT devices. Thus, any added security primitive must take in-concern with the resource-restricted environment in terms of power consumption. After applying the appropriate security measures, this paper analyses the security requirements for the message queuing telemetry transport (MQTT) protocol and adapts it with enhanced versions for a scenario-based setup. The paper provides a power consumption-based performance comparison of the enhanced security for resource-constrained devices.
