    摘要: A data storage unit can store an encrypted medium device key Enc (Kcu, Kmd_i), and a medium device key certificate (Certmedia). A controller can include an information recording unit to store a controller key (Kc) and first controller identification information (IDcu). A key generation unit executes a one-way function calculation based on the controller key and the first controller identification information to generate a controller unique key (Kcu). An identification information generating unit executes a one-way function calculation based on the controller key and the first controller identification information to generate second controller identification information (IDcntr). A key encryption unit encrypts the medium device key (Kmd_i) by the controller unique key (Kcu) to generate encrypted medium device key Enc (Kcu, Kmd_i). A key exchange unit executes an authentication key exchange process with a host device using the medium device key (Kmd_i) and the medium device key certificate (Certmedia).

    摘要: A recording device comprises a memory unit configured to be communicationable with an external device and to record key data for encryption of content data through an authentication process, and a controller which controls the memory unit. The memory unit comprises a normal recording unit which is accessible from the exterior through the controller without an authentication process, a protected recording unit which is accessible from the external device when authentication of a first authentication process completes, and a writing restricted/protected recording unit which is accessible from the external device when authentication of a second authentication completes and is unwritable and unaccessible from the external device when authentication of only the first authentication process completes.
