摘要： According to one embodiment, a storage system includes a host device, a secure storing medium, and a non-secure storing medium. The secure storing medium includes a memory provided with a protected first storing region which stores secret information sent from the host device, and a second storing region which stores encoded contents, and a controller which carries out authentication processing for accessing the first storing region. The host device and the secure storing medium produce a bus key which is shared only by the host device and the secure storing medium by authentication processing, and which is used for encoding processing when information of the first storing region is sent and received between the host device and the secure storing medium. The host device has the capability to request the secure storing medium to send a status.

摘要： According to one embodiment, a storage system includes a host device and a secure storage. The host device and the secure storage produce a bus key which is shared only by the host device and the secure storage by authentication processing, and which is used for encoding processing. The host device produces a message authentication code including a message which can be stored in the secure storage based on the bus key, and sends the produced message authentication code to the secure storage. The secure storage stores the message included in the message authentication code in accordance with instructions of the host device. The host device verifies whether the message stored in the secure storage is intended contents.
