According to one embodiment, a device includes a storage and an authenticator. The storage includes a first area, a second area and a third area. The first area stores NKey and SecretID, the second area stores index information. E-SecretID is generated by SecretID. The third area stores FKB including information generated by FKey. The authenticator authenticates the external device. HKey is generated by an AES encryption calculating using NKey and HC. A SKey is generated by an AES encryption process using HKey and RN. A one-way conversion calculating is performed. E-SecretID, FKB and Oneway-ID are output to the external device. The index information is read from the second area.

According to one embodiment, a device includes first and second data generator, a one-way function processor, and a data output interface. The first data generator generates a second key by encrypting a host constant with a first key in AES operation. The second data generator generates a session key by encrypting a random number with a second key in AES operation. The one-way function processor generates authentication information by processing secret identification information with the session key in one-way function operation. The data output interface outputs the encrypted secret identification information, a family key block, and the authentication information to outside of the device.
