Securing MQTT using Pseudo Random Number Generation
Anantha Raman Srikanthan, Gautam Srivastava · 2025
We are connected to The Internet of Things (IoT) and access more information by accessing a vast network of objects and systems. Still, secure connectivity in IoT environments plays a huge role to guard against the possible security threats and vulnerabilities. The Message Queuing Telemetry Transport (MQTT) protocol has emerged as one of the top choices among IoT protocols due to its simplicity and effectiveness. Here, we propose a novel secure mechanism for MQTT communication in IoT using password authenticated key exchange (PAKE) protocols along with one-time pad (OTP) and pseudo random number generation algorithm. Our methodology targets a variety of security issues such as authentication, confidentiality, authorization and performance enhancement while considering the constraints on IoT resources.
