Abstract:
According to one embodiment, an authenticator which authenticates an authenticatee, which stores first key information (NKey) that is hidden, includes a memory configured to store second key information (HKey) which is hidden, a random number generation module configured to generate random number information, and a data generation module configured to generate a session key (SKey) by using the second key information (HKey) and the random number information. The authenticator is configured such that the second key information (HKey) is generated from the first key information (NKey) but the first key information (NKey) is not generated from the second key information (HKey).

Claim (Index 7):
A system having a controller and a memory comprising:\n a storage area being used to store a first key, unique secret identification information, and encrypted secret identification information, the encrypted secret identification information being generated by encrypting the secret identification information, the first key and the secret identification information being prohibited from being read from outside, the encrypted secret identification information being readable from outside; a data generator configured to generate a session key by using a second key, the second key being generated based on the first key; and a one-way function processor configured to generate authentication information by processing the secret identification information with the session key in a one-way function operation as follows: the authentication information=AES E (the session key, the secret identification information)+the secret identification information, where AES stands for advanced encryption standard.
