摘要： Embodiments of compression and formatting of data for data storage systems are disclosed. In some embodiments, a data storage system can compress fixed sized data before storing it on a media and format obtained variable sized compressed data for storing on the media that typically has fixed size storage granularity. One or more modules compress the incoming host data and create an output stream of fixed sized storage units that contain compressed data. The storage units are stored on the media. Capacity, reliability, and performance are thereby increased.

摘要： Examples are disclosed for establishing a secure destination address range responsive to initiation of a direct memory access (DMA) operation. The examples also include allowing decrypted content obtained as encrypted content from a source memory to be placed at a destination memory based on whether destination memory addresses for the destination memory fall within the secure destination address range.

摘要： An article of manufacture includes a machine-readable medium that stores a multimedia content file in a first format and multiple program sets. Each program set is a version of software that, when executed by a respective electronic system, produces the multimedia content file in a second format for use in the respective electronic system. A first program set is compatible with a first operating system executed by a first electronic system and a second program set is compatible with a second operating system executed by a second electronic system. The second operating system is distinct from the first operating system.

摘要： Provided is an information processing device including a data processing unit that executes reproduction processing of content recorded in an information recording medium. The content includes an individual segment region formed of a plurality of variation data in which identification information different from each other is embedded and each of which can be decrypted by a different key, and a common segment region formed of single data. The variation data is formed of a 6144 byte aligned unit. The data processing unit calculates a reproduction path by applying a device key held in a memory, and selects an aligned unit corresponding to one variation data that corresponds to the calculated reproduction path from a plurality of aligned units configuring the plurality of variation data in the individual segment region included in the data read from the information recording medium, and then, executes the decryption and reproduction processing.

摘要： A technique to manage members of a group of decoders having access to broadcast data, each group member sharing a common broadcast encryption scheme (BES) comprising the steps of, in a stage for a decoder to become a group member, receiving keys pertaining to the position in the group according to the BES, receiving a current group access data comprising a current group access key, and in a stage of accessing broadcast data, using the current group access data to access the broadcast data, and in a stage of renewing the current group access key, sending a first group message comprising at lease a next group access key encrypted so that only non-revoked decoders can access it, said group message being further encrypted by the current group access key, updating the current group access key with the next group access key.

摘要： Generally, this disclosure provides systems, devices, methods and computer readable media for secure control of access control enablement and activation on self-encrypting storage devices. In some embodiments, the device may include a non-volatile memory (NVM) and a secure access control module. The secure access control module may include a command processor module configured to receive a request to enable access controls of the NVM from a user, and to enable the access controls. The secure access control module may also include a verification module configured to verify a physical presence of the user. The secure access control module may further include an encryption module to encrypt at least a portion of the NVM in response to an indication of success from the verification module.
