Abstract
An apparatus for connecting an Internet of Things (IoT) hub to a wireless network, the apparatus including: 1) a security module to generate a first secret and a second secret, and to encrypt a wireless key using the second secret to generate a first-encrypted key; and 2) a connection logic to establish a secure communication channel between an IoT hub and an IoT service using the first secret, transmit the second secret to the IoT hub and the first-encrypted key to the IoT service, receive from the IoT service a twice-encrypted key generated by encrypting the first-encrypted key using the first secret, and transmit the twice-encrypted key to the IoT hub, which decrypts it using the first secret to generate the first-encrypted key, which is further decrypted using the second secret to generate the wireless key. The IoT hub using the wireless key to connect to the wireless network.
