摘要： 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.

摘要： An information recording device uses a data storage device such as media having a built-in flash memory. When data is stored in the data storage device, different encryption keys are used for different sectors. Each encryption key is stored in the header of content. By using a single encryption key for a sector consisting of different blocks, the number of stored encryption keys is limited, and the amount of stored key data is reduced. In accordance with the type of encryption processing, for example, the single DES or the triple DES, one or at least two keys are selected for each sector in order to execute encryption or decryption processing on sector data.

摘要： 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.

摘要： In a content delivery system, delivery of content and charging the fee of the content are performed and managed in a highly secure and effective fashion. If a content-purchasing request is transmitted from a user device to a shop server, a charging process is performed. A user device authentication server, which manages content delivery, converts an encrypted content key KpDAS(Kc) encrypted using a public key of the user device authentication server (DAS) into an encrypted content key KpDEV(Kc) encrypted using a public key KpDEV of the user device. If the charging process is successfully completed, the shop server transmits, to the user device, the encrypted content key KpDEV(Kc).

摘要： 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.
