Push yoUr Password: Secure and Fast WiFi Connection for IoT Devices

Internet of things (IoT) is an indispensable paradigm in today's industrial change. IoT interconnects appliances around us through the Internet, and user's private information is deeply placed inside the network. Nonetheless, security vulnerabilities in IoT have not been addressed appropriately so far due to various reasons. Even in the initial WiFi connection procedures of IoT devices, WiFi credentials can be leaked, making the WiFi access point (AP) a hacking path. We propose a secure connection scheme, termed PUP, that aims to securely and quickly connect an IoT device to the AP in proximity while improving the user experience. PUP shows perfect security performance, enabling connection time within 11 s.
