Abstract: A memory system includes a nonvolatile memory and a controller that controls the nonvolatile memory. The controller is configured to generate information relating to encryption and decryption of data based on a location of the memory system and to enable at least one process of encrypting data to be written to the nonvolatile memory or decrypting data read from the nonvolatile memory by using the information.

Abstract: According to one embodiment, a storage device includes a nonvolatile storage medium and a controller. The controller encrypts data with an encryption key, writes encrypted data into the storage medium, and manages a first and second encryption keys. The first encryption key encrypts data to be written into a first area and a second encryption key encrypts data to be written into a second area. The controller updates, if the first area is write protected and the second area is not write protected, the second encryption key without updating the first encryption key when receiving an initialization command from a host.

Abstract: A storage device includes a storage and a controller. The controller receives commands from a host, and queues, in a command queue, the commands received from the host. The controller queues a first command, which is a command to request changing a security setting of a partial area of the storage, a second command, which is a command to access the partial area of the storage, and a third command, which is a command to access an area of the storage other than the partial area, after queuing the second command. The controller changes order of the commands queued in the command queue so that the third command is executed before the second command is executed.

Abstract: A storage device includes a non-volatile memory having a plurality of storage areas. Received data is encrypted with a first cryptographic key and stored in one of the storage areas. Upon receiving an request from a host, a key processor replaces the first cryptographic key used to encrypt data stored on a specified one of the non-volatile memories with a different cryptographic key not previously used for any of the storage areas by generating a second cryptographic key, converting the previously used keys into first value by an operation, converting the candidate key into a second value by the same operation. The first and second values are compared, and when the first information is not the same as the second information, the second cryptographic key replaces the first cryptographic key, and when not, the second cryptographic key is discarded and a new second cryptographic key generated.
