With the advent of the Internet-of-Things (IoT), there has been a wave of wireless protocols aimed at providing communication between connected devices. One of the most widely used protocols is Zigbee, a derivative of the IEEE 802.15.4 protocol for building low power mesh networks. Whilst Zigbee has largely found a use in consumer grade devices, it has also been explored as a protocol for use in industrial and building automation systems. A number of vulnerabilities have been found within the Zigbee and IEEE 801.15.4 standard which could damage the integrity of the transmitted data. Therefore, we propose a solution wherein a RESTful HTTPS protocol is transmitted over Zigbee networks, effectively providing a double layer of security. We demonstrate that RESTful HTTPS over Zigbee is possible, and evaluate its performance.
