摘要：According to one embodiment, a device includes first and second datagenerator, 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 AESoperation. The second data generator generates a session key by encrypting a randomnumber with a second key in AES operation. The one-way function processor generatesauthentication information by processing secret identification information with thesession key in one-way function operation. The data output interface outputs theencrypted secret identification information, a family key block, and the authenticationinformation to outside of the device.
