Abstract
An administrator can use an administrative-wireless-device to control a target wireless device using an SMS message to convey a command. The data of the command message can be encrypted to prevent malicious attacks. The encrypted data may include a universal device identifier unique to the target device, the phone number of the administrative-wireless-device, and a time stamp memorializing command or message creation. Before executing the command, however, the target device compares the phone number of the administrative-wireless-device with the number identified with the incoming SMS message to authenticate the administrative-wireless-device.
