Abstract
In a client/server system that authenticates according to a terminal ID, a terminal authentication apparatus is provided that is capable of authenticating a terminal device correctly even if the method of generating a terminal ID has been changed from the old version to a new one, and thus useful as an authentication apparatus for a net TV, mobile phone, on-line network for ATMs, and the like. The apparatus transmits two terminal IDs generated with the generation methods in both old and new versions. With this method, the server authenticates from these two terminal IDs according to the ID fields of the old and new versions, and additionally updates the ID in the old version to a new one.
