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 9):
A system having a controller and a memory device controlled by the controller, comprising\n a first area which stores first key data and unique first data, and is prohibited from being read from outside; and a second area which stores encrypted first data generated by encrypting the first data, and is readable, and wherein the system is configured to: perform an AES (Advanced Encryption Standard) encryption process using the first key data and externally-provided second data to generate second key data, perform an AES encryption process using the second key data and externally-provided third data to generate third key data, the third data being externally received, and perform a one-way conversion process using the third key data and the first data to generate fourth data used for authentication with an external device.
