  • Patent number: 9418022
    Abstract: According to one embodiment, a storage system includes a host device, 2 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.
