摘要:
A computer system is disclosed. The computer system includes a storage device, a device controller and a chipset. The device controller includes lock registers having values that correspond to the ranges of locked sectors of the storage device. The lock registers verify if a storage device access request is targeted for ranges of sectors of the storage device that are locked. The chipset includes an embedded controller to authenticate the storage device access request and to manage configuration of the storage device.

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.

Embodiments of an invention for cryptographic key generation using a stored input value and a stored count value have been described. In one embodiment, a processor includes non-volatile storage storing an input value and a count value, and logic to generate a cryptographic key based on the stored input value and the stored count value.
摘要:
In some embodiments an embedded processor is to participate in cryptographic key exchange with an audio software application, and a key exchange communication path is coupled between the audio software application and the embedded processor. Other embodiments are described and claimed.
摘要:
Keying materials used for providing security in a platform are securely provisioned both online and offline to devices in a remote platform. The secure provisioning of the keying materials is based on a revision of firmware installed in the platform.
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.
摘要:
A method and apparatus for preserving the processing order of some requests in a system is disclosed. The method may include blocking requests from executing based on a blocked count data field, blocking list data field, and a last request data field. The apparatus may include a system or a memory device.
