FIELD: physics, computer engineering.SUBSTANCE: invention relates to license management. A licence management device initiates the transition of a wireless device to a state where all functions are restricted usage functions by rewriting key information of the wireless device with a standard key which is specific for the wireless device. A key generating device generates an update key which is specific for the wireless device and transmits the update key to the licence management device.
