A method is provided that determines authenticity of a second recording medium mounted in a second device by using a first device mounted with a first recording medium. A non-user area of the first recording medium previously records first identification information and first algorithm data. A controller of the first recording medium causes a first display device to display a first image pattern and, after display of the first image pattern, causes a first imaging device to capture a second image pattern displayed on a second display device of the second device. The controller decodes first code data from the second image pattern and utilizes the first algorithm data to perform arithmetic that uses the first identification information and a first variable value. The controller determines the second recording medium to be authentic if the decoded first code data matches an arithmetic result.

The present disclosure provides an on-board secure storage system capable of easily and quickly detecting unauthorized access to a storage device and a failure of the storage device, and appropriately using the detection result. the on-board secure storage system includes the storage device that has a controller, a non-volatile memory and an interface, and an electronic control unit that electronically controls a vehicle. After determining that unauthorized access or a failure occurs in the non-volatile memory, the controller performs predetermined processing according to the type of the unauthorized access or failure.

On-board secure storage system for detecting unauthorized access or failure and performing predetermined processing

The present disclosure provides an on-board storage system in which the time required for initializing a storage device is substantially shortened by devising a backend start timing. The on-board storage system includes: a storage device that has a controller, a NAND flash memory, and an interface; an electronic control unit that electronically controls a vehicle; and a sensor. The electronic control unit communicates with the storage device through the interface, the sensor transmits a detection result of the sensor to the electronic control unit, and the electronic control unit transmits a command to start initialization of the NAND flash memory to the controller when the transmitted detection result of the sensor indicates a driving-start preliminary operation.

On-board storage system for shortening time required for initializing storage device

In an information processing device serving as a PCIe system including a host device and a plurality of memory devices, one of the plurality of memory devices is defined as a master memory. The other memory devices are defined as slave memories, and are logically coupled to the master memory. The plurality of memory devices thus constitute a single virtual storage. When accessing is performed from a root complex to the plurality of memory devices constituting the single virtual storage, the root complex hands over a bus master to the master memory. The master memory receives a command regarding the accessing from the root complex, changes address information used for the accessing in the command regarding the accessing, based on a logical relationship with the slave memories, and sends changed command regarding the accessing to the slave memories.

Information processing device

A cryptographic processing device comprises a cipher control circuit operative to execute at least one of encryption of plaintext data and decryption of ciphertext data on the basis of conversion parameter data; and a memory cell array that includes a plurality of memory cells, the plurality of memory cells including: a memory cell in a variable state, in which a resistance value reversibly changes between a plurality of changeable resistance value ranges in accordance with an electric signal applied thereto; and a memory cell in an initial state, which does not change to the variable state unless a forming stress for changing the memory cell in the initial state to the variable state is applied thereto, a resistance value of the memory cell in the initial state being within an initial resistance value range which does not overlap with the plurality of changeable resistance value ranges, wherein in the memory cell array, data including the conversion parameter data is stored on the basis of whether each of the plurality of memory cells is in the initial state or the variable state.

An encryption and recording apparatus storing data, the apparatus including: a first nonvolatile memory; a second nonvolatile memory; and an encryption and decryption control unit, wherein the encryption and decryption control unit: manages an area included in the second nonvolatile memory on a per-block basis, and manages association between a block and a block-unique key using key management information stored in the first nonvolatile memory; receives the data and corresponding information associated with the data; encrypts the data, using one or more block-unique keys associated with one or more blocks included in the second nonvolatile memory and writes the data to the one or more blocks; and stores the corresponding information into the key management information, associating the corresponding information and the one or more block-unique keys.

Encryption and recording apparatus, encryption and recording system, and encryption and recording method

A secure LSI deviceincludes an encryption sectionfor encrypting a program, and an external I/Ffor inputting/outputting a program or data from/to an external memory. In the encryption section, the operation of a private key arithmetic processing sectionis prohibited with respect to a sequence whose execution is determined by a key-generation/update sequencerto be impermissible. In the external I/F, a program processing sectionand a data processing sectionare structured independently from each other.

Provided is a method that, in the case of managing areas of a non-volatile memory of an information recording module by a file system, increases the speed of processing for writing file data and file system management information, and furthermore prevents a decrease in the rewriting lifetime of the non-volatile memory. The information recording module () is provided with a page cache control unit () that stores page cache information () in the non-volatile memory () of the information recording module () and performs control such that a specific physical block is used as a cache when writing small-sized data. Also, an access module () is provided with a page cache information setting unit () that sets information necessary for page cache control in the information recording module (). The combination of the access module () and the information recording module () prevents the execution of needless saving process with use of page caching when writing small-sized data, thereby increasing the speed of writing processing.

Chair

Provided is a chair suited to the use of a keyboard or mouse, the chair has a seatand a rocking backrest. The seatcomprises a first sectionand a second section. The first sectionof the seatis affixed to a seat-mounting shellis attached to a base, via a seat-mounting fixture, so as to be slide forwards and backwards. The backresthas a back cover, a back paneland a cushion move downwards while rotating in a seesaw fashion during rocking. The front end of the back coveris connected to the seat-mounting fixtureby means of a connecting pin. When the chair rocks, the seatmoves forwards as a whole while the second sectiontilts backward.

An access deviceinternally includes a logical-physical empty capacity management partfor obtaining information of a remaining capacity on a write once memory from a write once recording deviceA. In addition, the write once recording deviceA internally includes a physical empty capacity management partfor managing a remaining capacity on the write once memory and notifying the access device of the capacity. Prior to recording of file data, the access devicecan know an accurate remaining capacity of the write once recording device by: obtaining a remaining capacity of the write once memory from the write once recording deviceA; and comparing the capacity with a remaining capacity on an FAT to decide an actually-recordable remaining capacity for file data.

Write once recording device

A recording medium () for storing content that can be read and written by a host device stores a content key (a key that is used for encrypting content) () encrypted in a first format, and a content key () that is encrypted in a second format for content that is the same as the content related to the content key () encrypted in the first format. The first format is, for example, a format used for distributed content, and the second format is a format used with local content.
