    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： Embodiments of techniques and systems for out-of-band verification of host OS components are described. In embodiments, a out-of-band host OS boot sequence verification system (“BSVS”) may access system memory without detection by a host OS process, or “out of band.” The BSVS may access host OS components in the system memory and may generate signatures from memory footprints of the host OS components. These signatures may then be compared to trusted signatures to verify integrity of the host OS components. In embodiments, this verification may be performed during a boot of a host OS or on demand. In embodiments, the trusted signatures may be pre-stored by the BSVS before a boot; in some embodiments, the trusted signatures may be previously-computed and then stored by the BSVS. Other embodiments may be described and claimed.

    摘要： The present disclosure is generally related to embedding public key infrastructure information to a system-on-chip (SOC). The method includes generating a key pair including a public key and a private key. The method includes creating a digital certificate corresponding to the public key. The method includes signing the digital certificate with a unique signature. The method includes extracting the public key and the unique signature into a key file, wherein the key file is to be stored in a plurality of silicon fuses on the SOC.

    摘要： A system architecture provides a hardware-based root of trust solution for supporting distribution and playback of premium digital content. In an embodiment, hardware root of trust for digital content and services is a solution where the basis of trust for security purposes is rooted in hardware and firmware mechanisms in a client computing system, rather than in software. From this root of trust, the client computing system constructs an entire media processing pipeline that is protected for content authorization and playback. In embodiments of the present invention, the security of the client computing system for content processing is not dependent on the operating system (OS), basic input/output system (BIOS), media player application, or other host software.

    摘要： In one embodiment, a method is provided that may include, issuing a read request to request reading of at least one portion of data stored in a first storage device and issuing a write request to request writing of the at least one portion of the data into a second storage device or at least one location in the first storage device. The at least one location may be comprised in a volume of a redundant array of expensive disks (RAID). The method of this embodiment also may include, if a request to access one or more other portions of the data is received and/or issued by one or more operating system processes while the reading and/or the writing is occurring, issuing an access request to request accessing of the one or more other portions of the data. Of course, many modifications are possible without departing from this embodiment.
