A Secure MQTT Protocol, Telemedicine IoT Case Study

Abstract

The Message Queue Telemetry Transport (MQTT) application layer protocol is widely used in Internet of Things (IoT) platforms. The MQTT standard has no mandatory requirements regarding the security services. A telemedicine is one of the IoT applications that mandates a critical level of security especially when it comes to human life. In this work, the weaknesses of MQTT are addressed and a modified protocol is proposed. This protocol mandates security aspects such as authentication, key exchange, and confidentiality. The protocol is proved to achieve its claims and is incorporated into a telemedicine environment as a critical environment for security.
