Low-Energy Authentication with Selective Privacy for Heterogeneous IoT Devices in Smart-Farms

This paper presents a payload-based security model for authenticating constrained and heterogeneous constrained devices in a smart-farm application. The domain ideally operates with optional internet and no constant power supply, using battery-powered microcontrollers for the monitoring and control of aquaponics systems. The motivation was to reduce energy consumption for extended battery life, whilst enabling a robust, decentralised security design. Results demonstrated an annual saving of up to 96 % device battery life when compared to recommended TLS implementation, whilst maintaining equally high security standards.
