Abstract:
A license management device causes a wireless device to enter a state in which all functions are restricted by overwriting key information of the wireless device with a default key specific to the wireless device. A key generating device generates an upgrade key specific to the wireless device, and transmits the update key to the license management device. The license management device can release a restriction of a function in the wireless device by applying the upgrade key to the key information of the wireless device overwritten with the default key.
