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.

摘要： A controller is provided with a controller key and a first controller identification information unique to the controller. The controller generates a controller unique key unique to a respective controller based on the controller key and the first controller identification information, and a second controller identification information based on the first controller identification information. A decryptor decrypts the encrypted medium device key using the controller unique key to obtain a medium device key. An authentication/key exchange process unit performs authentication/key exchange process with the host device through an interface unit using the medium device key, the medium device key certificate and the second controller identification information to establish a secure channel.

摘要： According to one embodiment, encrypted secret identification information (E-SecretID) and the key management information (FKB) are read from a memory device. Encrypted management key (E-FKey) is obtained using the key management information (FKB) and index information (k). The index information (k) and the encrypted management key (E-FKey) are transmitted to the semiconductor memory device. An index key (INK) is generated using the first key information (NKey) and the received index information (k). The encrypted management key (E-FKey) is decrypted using the index key (INK) to obtain management key (FKey), which is transmitted to the host device.
