Research Area:  Internet of Things
In this paper, a security mechanism for MQTT-enabled Internet of things (IoT) using a simple thin cryptographic process has been proposed. The key benefits of the proposed security mechanism are the simplicity, resilience to attacks, energy efficiency, and the speed of cryptographic computations such that it can be computed quickly. The encryption of MQTT payload is performed using lightweight operations so that a smaller amount of node energy is consumed in the process. To test the effectiveness of the proposed mechanism, Contiki-based simulation setup is created, wherein the implementation of the proposed solution is performed and tested in Cooja simulator. The analysis depicts that the proposed solution consumes less energy for enciphering data, provides security against possible attacks like spoofing attack and brute-force attack, and has tiny code footprint. It is contemplated that the proposed security solution can be used in protecting message confidentiality in the Internet of things environment and other low-power wireless networks.
