    摘要: Example embodiments relate to combining hashes of data blocks. The examples disclosed herein calculate a hash value for each data block in a sequence of data blocks. The hash values are combined into a combined value, where the combined value has the same sequence as the sequence of data blocks. A master hash value is then calculated for the combined value.

    摘要: A Trustonic DRM Plug-in is provided that can be downloaded and operate in conjunction with an Android framework. The solution also includes a PVP with the downloadable DRM. The system includes components that can be added by Trustonic based on the Android 4.3 Framework in addition to current t-base 300 that can be used by any DRM vendor. The system enables the DRM to be downloaded in the field since all DRMs could use the standard API services of the Android 4.3 OS. With a codec component employed like H.264 or HEVC that can use the PVP with the downloaded DRM component, the Android video player can use the component to satisfy HD content security requirements.

    摘要: Cryptographic hashing circuitry such as mining circuitry used to mine digital currency may be formed on an integrated circuit. The hashing circuitry may include sequential rounds of register and logic circuitry that perform operations of a cryptographic protocol. A final hash value output by the hashing circuitry may include hash values stored at previous rounds of the cryptographic hashing circuitry. The hashing circuitry may be formed with only two registers per round, thereby optimizing chip area consumption. The hashing circuitry may perform sequential rounds of cryptographic hashing based on an initial hash value and multiple message words. One or more message registers may store the message words. Control circuitry may selectively route the message words from the message register to the hashing circuitry using pointers. If desired, the message registers may be replaced by one or more arrays of memory elements read using row and column pointers.

    摘要: Techniques for HTTP header compression are described herein. In an implementation, an electronic device may be configured to enable compression/decompression of HTTP messages, including compression/decompression of information in the headers of the messages. A HTTP message is generated that contains at least a header and a body. The HTTP message is reformatted to place at least some of the header information into the body. Then, the body of the reformatted message having the header information is compressed to form a compressed HTTP message. Decompression may be applied by a recipient of the compressed HTTP message to reconstruct the original HTTP message.
