摘要： 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.

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.

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 and the medium device key certificate to establish the secure channel.
