Key distribution in Wireless Sensor Networks (WSNs) is challenging issue because a WSN is a network of resource-constrained nodes that carry limited-power batteries. Therefore, a key distribution scheme for WSNs must be an energy and memory efficient.Β In this poster, we proposed an energy-efficient hybrid key distribution scheme that is designed to suit the resource-constrained devices such as WSNs. We utilized Arduino UNO microcontroller and OPNET Modeler to investigate our proposed scheme in comparison to key distribution schemes in the literature. The findings show that our scheme achieves security and consumes less energy compared to other schemes in the literature. less energy
