Abstract
A method and system for connecting an Internet of Things (IoT) hub to a wireless network. One embodiment of the method includes establishing a secure communication channel between an IoT hub and an IoT service through a client device using a first secret; generating a second secret on the client device and transmitting it to the IoT hub; encrypting a wireless key using the second secret to generate a first-encrypted key and transmitting it to the IoT service; encrypting the first-encrypted key using the first secret to generate a twice-encrypted key and transmitting it to the IoT hub over the secure communication channel; decrypting the twice-encrypted key at the IoT hub using the first secret to generate the first-encrypted key and decrypting it using the second secret to generate the wireless key usable to establish a secure wireless connection between the IoT hub and the local wireless network.
