PXPM: An Encryption Technique to Enhance Security of MQTT Based IoT Systems
Jeyarasa Pratheepan
Abstract:
IoT devices are elements of an IoT system that operate through the internet, allowing the transfer of messages among elements and people automatically. The exploitation of IoT devices in numerous applications not only permits services to users and gives technical innovations but also generates several conditions based on the IoT network and security. Generally, IoT devices are limited with fewer and slower processing resources and less powerful batteries. MQTT is the most commonly used messaging protocol in IoT applications because it requires small computational resources and bandwidth. TLS/SSL encryption technology is used to provide security on MQTT. The implementation of this encryption technique needed more computational power and expensive as well.
