Abstract: Between a data recording/playback device and a data storage device, CBC-mode encryption processing is executed which encrypts a plurality of encryption keys of content which correspond to sectors. The encrypted data is stored in a header corresponding to the content. The CBC-mode encryption processing is executed by using a storage key unique to media in which the content is stored. For using the content, only by decrypting the key data in media in which mutual authentication is established, the content can be used, so that highly-secure key storage is implemented.

Abstract: To provide a memory access control system in which partitions, which are divided memory areas generated in a device, can be independently managed. In response to access to the divided memory areas, which are a plurality of partitions, various types of access control tickets are issued under the management of each device or partition manager, and processing based on rules indicated in each ticket is performed in a memory-loaded device. A memory has a partition, which serves as a memory area managed by the partition manager, and a device manager management area managed by the device manager. Accordingly, partition authentication and device authentication can be executed according to either a public-key designation method or a common-key designation method.

Abstract: An information recording device includes a control unit and a memory interface unit. An ICV for each sector data of data to be stored in units of sectors is stored in the redundant part of each sector. An ECC and an ICV are stored in the redundant part of each sector, so that sector-unit ICV storage can be performed without reducing the storage capacity of the data part of the sector. processing that combines data parts by using the file system of a device can be performed similarly to conventional data combination processing that only combines data parts in which ones purely used as data are stored. The control unit does not have any load because only each sector which is regarded as valid (no interpolation) as a result of ICV checking is transmitted to the control unit, and the ICV checking is performed by the memory interface unit.

Abstract: A data processing device includes a memory interface (I/F) unit and a control unit. When accessing a data storage device such as a memory card having a built-in flash memory, the data processing device sets a block permission table (BPT) as an access permission table in the memory I/F unit, whereby only when the BPT permits a process to be executed does the memory I/F unit access the storage device, and the memory I/F unit does not execute a process when it is out of an allowable range. Regardless of a process type performed by the control unit and a command type, the memory I/F unit always accesses the storage device in accordance with the BPT set in the memory I/F unit. This effectively prevents the rewriting of data in rewrite-prevented recording media.
