Method and system for controlling access to wireless apparatuses
A system for securely controlling access between two wireless (i.e. Bluetooth-enabled) apparatuses, also comprising a supervisor apparatus. The first apparatus is paired to the second by establishing a secure wireless (i.e. Bluetooth) link. The first apparatus includes a stored partial link key and a link key generator: The first apparatus receives a first secret key from the apparatus user, and may also receive a second secret key from the supervisor apparatus. The link key generator generates either a first link key based upon a stored first partial link key, the first secret key and the second secret key or a second link key based upon the stored first partial link key and the first secret key. An access control module in the second apparatus determines the level of access that the first apparatus is granted based upon the link key used to establish the secure connection—full/restricted access.
