Automatic and secure Wi-Fi connection mechanisms for IoT end-devices and gateways

Abstract

Internet of Things (IoT) are developed rapidly in recent years and more than 50 billion of IoT devices are expected to be deployed worldwide in 2020. How to automatically and securely connect the tremendous number of IoT end devices to Internet is one of critical problems to be addressed. This paper proposes secure and automatic Wi-Fi (Wireless Fidelity) connection mechanisms for connecting IoT end devices and IoT gateways. Our design has the following advantages. First, IoT end devices, once powered on, can automatically connect to an IoT gateway without human intervention. Secondly, the SSID and password for high security strength WPA2 connection are randomly generated to enhance IoT security. Finally, the randomly generated password and SSID are automatically changed every day or when network attacking is detected.
