Selective privacy in IoT smart-farms for battery-powered device longevitySteph Rudd, Hamish Cunningham
This paper presents a payload security model to maintain the standards of TLS whilst removing obstacles associated with constrained devices and IoT network protocols. The domain of aquaponics as a smart-farming environment was used to test the novelty with ESP32 edge devices. The impact of privacy on message content illustrated the most appropriate security attribute configurations, followed by time and power analysis to calculate energy consumptions of each scenario. It was concluded that using this tailored payload security model rather than TLS was capable of extending the battery life of constrained devices by up to 81%, whilst maintaining TLS security standards, and applicable to various protocols.
