摘要： An apparatus and method which can achieve high-speed data processing and long memory life and is effective to elimination of defragmentation of data, for example, is provided. A recording medium includes a logical-physical conversion table for storing correspondence of a logical address to a physical address of a block in a recording region. The recording medium has a function of replacing correspondence of a logical address to a physical address in the logical-physical conversion table, for a set of logical addresses. A data processing apparatus issues a replace command to the recording medium so that data can be rearranged on a consecutive region in the logical address space, thereby eliminating defragmentaion on the logical address space.

摘要： Provided is a method for performing high-speed search for a content key associated with encrypted content in the case of a key-separation-type content management method where content keys and their respective pieces of encrypted content are correlated by ID information and stored in different recording media. An external recording medium is used to store a plurality of content files that contain: their respective pieces of encrypted content that are encrypted with different encryption keys; and their respective content IDs, each being associated with a corresponding piece of the encryption content, and a semiconductor recording medium is used to store a list that contains: pieces of encryption key storage location information, each indicating where a corresponding one of the encryption keys is stored; and the content IDs, the list being sorted in accordance with the content IDs. When encrypted content is played back, the list is searched to find encryption key storage location information associated with a content ID that matches the content ID of the encrypted content, and the encryption key is read based on the encryption key storage location information.

摘要： A domain key is used to perform chaining decryption with respect to encrypted content key information (ST203-1), and first data is extracted (ST203-2). The extracted first data is compared with partial-check data (ST203-4). The first data as it is encrypted is extracted from the m pieces of encrypted content key information (ST203-6), and a predetermined operation is executed with respect to concatenated data including m extracted check values to generate second data (ST203-8). The second data is compared with whole-check data included in domain key information (ST203-11). If the first data matches the partial-check data (ST203-5) and the second data matches the whole-check data (ST203-12), it is determined that there is not tampering.
