A universal iot joining protocol for DIY applications

摘要

Previous work has developed a remarkably low cost method which allows IoT devices to securely join domestic WiFi networks. Implementation of this method has uncovered a weakness in that only controllers (usually smart phones) capable of programmatically controlling hotspot mode can successfully implement the protocol. It is demonstrated that this weakness greatly compromises the open nature of this protocol and is unacceptably incompatible with a significant number of popular devices. This paper reorients the original protocol to move the hotspot functionality to the IoT device. This updated protocol allows any WiFi capable device to act as a joining agent and controller for a household full of IoT devices, achieving universal compatibility with all popular devices.
