Abstract
A data blob has an operator's certificate that specifies a network. The data blob is encrypted by the network using a private key that authenticates that a user device owns a MAC address. The network sends the encrypted data blob to the user device, which decrypts it using a private key that is locally stored in the user device. From that the user device obtains the operator's certificate, locks the user device to a network specified by the operator's certificate, and sends a response message signed with the private key. The network grants access to the user device based on the signed response message. Various embodiments and further details are detailed. This technique is particularly useful for a WiMAX or WLAN/WiFi network in which there is no SIM card to lock the device to the network.
