摘要： An access management system such as an AACS is used to protect highly confidential information. A specific content is deleted from a medium on which reco=ded are one or more contents or objects being encrypted using an encryption key (or Title Key) according to the AACS. When the contents are to be deleted (ST400), the contents and the encryption key will be deleted simultaneously (ST404), provided that the information medium does not record another content or another object encrypted using an encryption key which is equivalent to the encryption key used for encrypting the contents to be deleted (ST402N).

摘要： A rights management arrangement for storage media such as optical digital video disks (DVDs, also called digital versatile disks) provides adequate copy protection in a limited, inexpensive mass-produceable, low-capability platform such as a dedicated home consumer disk player and also provides enhanced, more flexible security techniques and methods when the same media are used with platforms having higher security capabilities. A control object (or set) defines plural rights management rules for instance, price for performance or rules governing redistribution. Low capability platforms may enable only a subset of the control rules such as controls on copying or marking of played material. Higher capability platforms may enable all (or different subsets) of the rules. Cryptographically strong security is provided by encrypting at least some of the information carried by the media and enabling decryption based on the control set and/or other limitations. A secure 'software container' can be used to protectively encapsulate (e.g., by cryptographic techniques) various digital property content (e.g., audio, video, game, etc.) and control object (i.e., set of rules) information. A standardized container format is provided for general use on/with various mediums and platforms. In addition, a special purpose container may be provided for DVD medium and appliances (e.g., recorders, players, etc.) that contains DVD program content (digital property) and DVD medium specific rules. The techniques, systems and methods disclosed herein are capable of achieving compatibility with other protection standards, such as for example, CGMA and Matsushita data protection standards adopted for DVDs. Cooperative rights management may also be provided, where plural networked rights management arrangements collectively control a rights management event on one or more of such arrangements.

摘要： The invention relates to an information carrier for holding user information, the information carrier comprising access information for accessing the user information, the access information being stored in a pre-determined first region on the information carrier. The information carrier further comprises at least one further region different from the first region, the further region comprising dummy information. The invention is based on the insight that the noise level of a read out signal increases somewhat in the region(s) where the access information is hidden. To avoid this difference in noise level between regions with and without the access information, this access information is assigned for only a specific region of the information carrier, but dummy information is also written in other regions. Due to this, an improved copy protection system against illegal read out of the user information present or to be present on the information carrier is realized.

摘要： A system is described for protecting digital content stored (112) on a storage medium (108) from unauthorized copying. The system includes a number generator to generate a nonce, an encryption subsystem (114) and a decryption subsystem (128). The encryption subsystem encrypts data accessed from a storage medium containing a key distribution data block (MKB,110) using an encryption bus key (124) prior to transmitting the encrypted data via a data bus (106). The encryption bus key is derived based on at least a portion of the key distribution data block (110), at least one device key (116) assigned to the encryption subsystem and the nonce generated by the number generator. The decryption subsystem is coupled to the data bus to decrypt the encrypted data received over the data bus using a decryption bus key (140) derived based on at least a portion of the key distribution data block, at least one device key (130) assigned to the decryption subsystem and the nonce generated by the number generator.

摘要： A device key 46 is implemented on a drive 4 side. To securely transmit the device key 46 to a host 5, the device key 46 is encrypted with a bus key. The host 5 side decrypts the device key with the bus key. A medium unique key calculating block 55 calculates a medium unique key with an MKB 12, a medium ID, and the decrypted device key 46. When the calculated medium key is a predetermined value, the drive 4 is revoked and the process is stopped. The medium unique key is supplied to an encrypting/decrypting module 54. A content key is obtained with an encrypted title key 14 and a CCI 15. With the content key, an encrypted content is decrypted and a content that is recorded is encrypted.

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.

摘要翻译： 存储在信息记录介质中的内容以每单位为基础进行管理，并且防止未经授权的使用。 存储在信息记录介质中的内容被分成单位，并且使用为每个单元生成的单元密钥对内容进行加密。 基于各种密钥生成信息生成单位密钥生成密钥。 通过将与每个单元对应的记录种子应用于单元密钥生成密钥来生成每个单元的单位密钥。 例如，基于单位密钥生成块密钥，并且为每3个扇区设置块单元生成块种子。 使用块密钥以每块为单位进行加密处理。 在解密期间，允许内容的解密取决于密钥生成信息，记录种子和存储在盘中的块种子的匹配。 因此防止了未经授权使用内容。
