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 3):
A device having a controller and memory storage, comprising:\n a first storage area used to store a key, the first storage area being prohibited from being read from outside the device; unique identification information stored outside of the first storage area; a first generator which generates first key data using information received from outside the device and key data stored in the device; a second generator which generates second key data using the first key data; and a third generator which generates third key data using the second key data and the unique identification information.
