Techniques are described for using public key cryptography and blockchain methods to automatically and securely on-board Internet of Things (IOT) devices. This is an improvement over typical approaches in which IOT devices are on-boarded to Wi-Fi® networks with a pre-shared key that could be built-in or configured through out-of-band connectivity (e.g., Bluetooth®, Wi-Fi Protected Setup (WPS), etc.).
