Abstract
A network terminal, e.g., a smartphone, can retrieve, from a datastore, a cryptographically-signed configuration record including a device identifier of the terminal. The terminal can transmit a request message comprising the configuration record and the device identifier. A network device can verify authenticity of the device identifier and a match between the identifier in the record and the identifier in the message. In response to confirmation of the request by a policy engine, the network device can determine a reply message comprising a cryptographically-signed second configuration record that includes a second device identifier. The terminal can verify that the signature is valid and that the second device identifier matches the device identifier. In response, the terminal can modify data in the datastore according to the second configuration record. The configuration record can lock or unlock the terminal, or determine permitted services or network peers.
