Abstract:
A target sends ID of a key table. The apparatus receives the ID. The apparatus sends ID of an authentication table to the target. The apparatus sends a challenge corresponding to a pair of the ID of the key table and the ID of the authentication table, to the target. The target obtains, from the key table, a key corresponding to a pair of the ID of the key table and the ID of the authentication table. The target generates a response from the challenge and the key. The target sends the response to the apparatus. The apparatus obtains, from the authentication table, a response corresponding to a pair of the ID of the key table and the ID of the authentication table. The apparatus authenticates the target based on the responses.
