  • Publication number: 20200236191
    Abstract: According to one embodiment, a memory system includes a non-volatile semiconductor memory device, a control unit, a memory as a work area, a wireless communication module, and an extension register. The control unit controls the non-volatile semiconductor memory device. The extension register is provided in the memory and has a data length by which a wireless communication function of the wireless communication module can be defined. The control unit causes the non-volatile semiconductor memory device to store, as a file, an HTTP request supplied from a host, causes the extension register, based on a first command supplied from the host, to register an HTTP transmission command transmitted together with the first command, and causes the wireless communication module to transmit the HTTP request stored in the non-volatile semiconductor memory device based on the transmission command registered in the extension register.

  • Patent number: 9449193
    Abstract: According to one embodiment, an information processing apparatus includes a nonvolatile semiconductor memory and a processor. The nonvolatile semiconductor memory stores identification information. The processor controls an application which executes authentication processing for authenticating validation of the identification information stored in the nonvolatile semiconductor memory. The processor executes the application to read the identification information from the nonvolatile semiconductor memory, and to execute the authentication processing for determining whether or not the identification information is authentic. When the identification information is authentic, the processor continues at least some processes of the application, and when the identification information is inauthentic, the processor ends at least some processes of the application.

  • 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.

  • Publication number: 20150341345
    Abstract: 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.
