摘要： A security system includes a controller manufacturer, a key issuer, and a medium manufacturer. The controller manufacturer writes a controller key Kc and a controller unique ID (IDcu) in the controller at the time of manufacturing the controller, and transmits the controller key Kc to the key issuer. The key issuer generates a medium device key Kmd_i and a medium device key certificate Certmedia, and encrypts the medium device key Kmd_i using the controller key Kc to generate encrypted medium device key Enc(Kc, Kmd_i). The medium manufacturer decrypts the encrypted medium device key Enc(Kc, Kmd_i) received from the key issuer, using the controller key Kc in the controller, and encrypts the medium device key Kmd_i obtained by decryption using a controller unique key Kcu generated from the controller unique ID (IDcu) in the controller, and then store it in a memory.
