    摘要: Embodiments of multinode hubs for trust operations are disclosed herein. In some embodiments, a multinode hub may include a plurality of memory regions, a trapping module, and a trusted platform module (TPM) component. Each memory region may be associated with and receive trust operation data from a coherent computing node. The trapping module may generate trap notifications in response to accesses to the plurality of memory regions by the associated coherent computing nodes. The trap notifications may indicate which of the plurality of memory locations has been accessed, and the TPM component may process the trust operation data in a memory region indicated by a trap notification. Other embodiments may be disclosed and/or claimed.

    摘要: An apparatus for secured playback is presented. In one embodiment, the apparatus includes a controller that includes a key derivation module to manage authentication and key derivation. In one embodiment, the apparatus provides a video decryption key to a graphics engine if video data portions in a data stream are retrievable without having to decrypt the data stream. In one embodiment, the apparatus also includes a decryption module to decrypt a part of data in conjunction with an encryption key to generate video information and video data. The controller then writes an encrypted version of the video data to a video buffer of a graphics engine.

    摘要: Apparatus, systems, methods, and articles, operate to create a log file in a non-volatile data storage medium. The log file includes a header record, a trailer record, and at least one partial parity value associated with a stripe in a redundant array of inexpensive disks (RAID) sub-system. The stripe includes a first data strip to be updated, the first data strip located on an operational first disk drive, a second data strip located on a failed disk drive, and a stripe parity strip located on an operational disk drive, among others.
