An End-to-End AES Based Cryptographic Authentication Mechanism for Communication on Internet of Things (IoT) Using MQTT

Abstract

Global Internet has been a revolutionary innovation in the field of global communication across the world that has
been usefully serving to the human society for last few decades. Applications of Internet include every field relating to human
society. Researchers as well as scientists are immensely involved in bringing in innovations into this communication
methodology everyday. However, the traditional Internet is limited in the fact that it is capable of facilitating human-to-human
communication only and devices can communicate on the Internet with human intervention only. Further innovation in
traditional Internet has led to emergence of Internet of Things (IoT) that could overcome this limitation thereby facilitating
device-to-device (D2D) or also referred to as machine-to-machine (M2M) communication wherein smart devices can
communicate autonomously via Internet without any human intervention. However, most of the smart devices can be
connected to the IoT environment via wireless channels which makes it vulnerable to various security threats to the
communication. IoT security has been a major point of focus these days for researchers and scientists across the world. In this
paper, we propose as end-to-end AES based cryptographic authentication mechanism for secure communication between the
IoT devices using Message Queue Telemetry Transport (MQTT) protocol. Experimental results justify the improved performance
of communication protocol MQTT.
