    摘要: An MKB and a device key 121 of a drive are input to a process MKB 122. The process MKB 122 performs a revoking process for the drive. A process MKB 132 performs a revoking process for a host 103. The host 103 compares MAC values calculated by MAC calculating blocks 123 and 133. When the host 103 has determined that the two values are the same, the host 103 has successfully authenticated the drive 102. The drive 102 compares MAC values calculated by MAC calculating blocks 134 and 124 of the host 103. When the drive 102 has determined that the two values are the same, the drive 102 has successfully authenticated the host 103. When the mutual authentication has been successfully performed, the MAC calculating blocks 125 and 135 generate a common session key.

    摘要: A configuration is provided wherein usage restrictions of an application are determined in accordance with timestamps. A certificate revocation list (CRL) in which the revocation information of a content owner who is a providing entity of an application program recorded in a disc is recorded is referred to verify whether or not a content owner identifier recorded in an application certificate is included in the CRL, and in the case that the content owner identifier is included in the CRL, comparison between a timestamp stored in a content certificate and a CRL timestamp is executed, and in the case that the content certificate timestamp has date data equal to or later than the CRL timestamp, utilization processing of the application program is prohibited or restricted. According to the present configuration, a configuration is realized wherein an unrevoked application is not subjected to utilization restriction, and only a revoked application is subjected to utilization restriction.

    摘要: An information processing apparatus includes a data processing unit that verifies data recorded on a disk and reproduces content recorded on the disk if a verification condition is satisfied. The data processing unit verifies the validity of an ID inserter that has recorded, on the disk, an ID corresponding to the disk. The data processing unit acquires an ID inserter certificate containing an apparatus ID of the ID inserter that has recorded the ID corresponding to the disk on the disk and an ID inserter blacklist having apparatus IDs of invoked ID inserters registered therein, determines whether the apparatus ID contained in the ID inserter certificate is registered in the ID inserter blacklist so as to verify the validity of the ID inserter that has recorded the ID corresponding to the disk, and stops reproduction of the content if it is determined that the ID inserter is not valid.

    摘要: In a process for manufacturing an information recording medium, a configuration is provided in which strict information management and an information recording medium manufacturing process are realized. In a configuration in which master data as original data of recording data for an information recording medium is generated and recording data for the information recording medium is generated on the basis of the master data, master data containing a dummy data area in a partial area of the master data is generated, and the dummy data area is identified and a process for setting significant information is performed on the basis of the stored information of an auxiliary file. Therefore, it is not necessary to obtain data of significant information when the master data is to be generated, and it becomes possible to generate the master data without obtaining specific information, such as an encrypted key block.

    摘要: A configuration for preventing information leakage in content use involving data transfer between different devices and illegal content processing is provided. In a content reproduction or recording process involving data transfer between different devices, such as a drive and a host, a media ID (disc ID) used for a content encryption or decryption process is read from a medium. The drive verifies whether the media ID has been recorded in such a manner as to correspond to a header code set on a correct valid medium. When the medium is confirmed to be a valid medium by the verification, on the drive side, the media ID is encrypted and output to the host. With this configuration outside leakage of the media ID, and a content reproduction or recording process using an invalid medium can be prevented.
