摘要： A data placement configuration which ensures seamless playback of contents having segment portions including multiple different variations of encrypted data is provided. With regard to contents having segment portions configured of multiple different variations of encrypted data to which individual segment keys have been applied, and non-segment portions serving as encrypted data to which a unit key has been applied, the placement of segment data and non-segment portion configuration data is determined such that the maximum jump distance executed at the time of playback processing is equal to or less than a maximum jump distance set beforehand. Data placement has been determined based on seek time, ECC block processing time, sequence key usage time which is key switchover time, and so forth.

摘要： The present invention relates to an encryption method for encrypting information including a series of multiple unit blocks, one at a time, a decryption method for decrypting multiple encrypted unit blocks, one at a time, and a recording and reproducing apparatus that uses those methods. The seed of an encryption key for encrypting each unit block and the seed of an encryption key for decrypting each encrypted unit block, which are used by those methods and the recording and reproducing apparatus, are based on a unit block that is one or more unit blocks before the current unit block in a reproduction order or on information generated by encrypting one or more unit blocks before the current unit block. Alternatively, the seed of an encryption key for encrypting each unit block and the seed of an encryption key for decrypting each encrypted unit block are information based on an encryption key for encrypting a unit block before the current unit block in a reproduction order.

摘要： A content stored in an information recording medium is managed on a per unit basis and protected from unauthorized use. The content stored in the information recording medium is divided into units, and the content is encrypted with a unit key generated for each unit. A unit key generation key is generated based on a variety of key generation information. The unit key for each unit is generated by applying a record seed corresponding to each unit to the unit key generation key. For example, a block key is generated based on the unit key and a block seed per block unit set for every 3 sectors. An encryption process is performed on a per block unit basis using the block key. During decryption, the decrypting of the content is permitted conditional on the matching in the key generation information, the record seed, and the block seed stored in a disk. Unauthorized use of the content is thus prevented.
