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 5):
A system having a controller and a memory controlled by the controller, comprising:\n a first storage area being used to store a first key and unique secret identification information, the first storage area being restricted from being read and written from outside; a second storage area being used to store encrypted secret identification information generated by encrypting the secret identification information, the second storage area being read-only; and a third storage area being readable and writable; wherein the system is configured to: generate a second key by using the first key; generate a session key by using the second key; generate first authentication information by processing the secret identification information with a session key in one-way function operation; and generate second authentication information and transmit the second authentication information after generating the session key. \u25a1
