description A system and method of securely controlling a device from another device. The user of the device attempts to modify the device in some way. In response to the attempted modification a request is generated and sent to a controlling device. The request includes information related to the desired modification. The controlling device analyzes the request and a determination on how to respond to the request is made. This response is encrypted at the controlling device and transmitted to the device. The device then decrypts the response and implements the indicated response to the request. The encryption and decryption keys are burned into the corresponding devices such that information needed to decrypt the response is not transmitted to the device.
