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.

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.

摘要翻译： 数据处理装置包括存储器接口（I / F）单元和控制单元。 当访问诸如具有内置闪存的存储卡的数据存储设备时，数据处理设备将存储器I / F单元中的块许可表（BPT）设置为访问许可表，由此仅当BPT允许 要执行的处理是存储器I / F单元访问存储设备，并且当存储器I / F单元超出允许范围时，存储器I / F单元不执行处理。 无论控制单元执行的处理类型和命令类型如何，存储器I / F单元总是按照存储器I / F单元中设置的BPT访问存储设备。 这有效地防止了重写防止记录介质中的数据重写。

摘要： 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.

摘要： A content use rights discrimination card corresponding to encrypted content is sold to a user. The user transmits data recorded on the content use rights discrimination card to a content use rights management center. The content use rights management center then verifies the content and the card, based on data in the received content use rights discrimination card, to encrypt a decoding key for decoding the content together with, for example, a session key, to transmit the encrypted content key to the user. The content use rights discrimination card, when sold to the user, can be set for enabling resale and transferred between different users so that the decoding key can be transmitted plural times from the content use rights management center. This procedure enables content to be utilized without executing any on-line settlement processing.

摘要： Content data encrypted with a content key, the content key encrypted with an individual key specific to an information sending device, and the individual key encrypted with a distribution key that is updated in a predetermined cycle, and supplied are sent to an information receiving device, and the information receiving device decrypts the individual key with the distribution key, decrypts the content key with the individual key, and decrypts the content data with the content key. Thus, the information sending device does not have the distribution key, and accordingly piracy of content data can be prevented with a simple configuration. Also, the information receiving device sends the content key and a playback command to other apparatuses. Thus, other apparatuses can play back contents using the playback command and the content key. Furthermore, the information sending device decrypts the content key with the distribution key before being updated, and stores the same. Thus, contents purchased by an advance order can be actually purchased regardless of expiration dates of the distribution key. Furthermore, usage right is passed from a first information receiving device to a second information receiving device different in registration information at the tome of using contents. Thus, contents can be used among information receiving devices different from each other in registration information.
