Abstract: Securely sharing content between a first system and a second system is provided. A hardware-based root of trust is established between the first system and a server. Content requested by a user and an encrypted license blob associated with the content is received by the first system from the server. A first agent on the first system connects with a second agent on the second system. The encrypted license blob and a sub-license request are sent from the first agent to a security processor on the first system. The first security processor decrypts the encrypted license blob, validates the sub-license request, and if allowed, creates a sub-license to allow the second system to play the content. The first security processor sends the sub-license to a security processor on the second system. The first system provides access to the content to the second system for future playback according to the sub-license.

Abstract: 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.

Abstract: Device memory protection for supporting trust domains is described. An example of a computer-readable storage medium includes instructions for allocating device memory for one or more trust domains (TDs) in a system including one or more processors and a graphics processing unit (GPU); allocating a trusted key ID for a TD of the one or more TDs; creating LMTT (Local Memory Translation Table) mapping for address translation tables, the address translation tables being stored in a device memory of the GPU; transitioning the TD to a secure state; and receiving and processing a memory access request associated with the TD, processing the memory access request including accessing a secure version of the address translation tables.

Abstract: 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.

Abstract: Apparatus and systems, as well as methods and articles, may operate to create a log file in a non-volatile data storage medium. The log file may comprise 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 may comprise a first data strip to be updated 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.
