摘要： An embodiment may include circuitry that may be capable of performing compression-related operations that may include: (a) indicating, at least in part, in a data structure at least one position of at least one subset of characters that are to be encoded as a symbol, (b) comparing, at least in part, at least one pair of multi-byte data words that are of identical predetermined fixed size, (c) maintaining, at least in part, an array of pointers to potentially matching strings that are to be compared with at least one currently examined string, and/or (d) allocating, at least in part, a first buffer portion to store at least one portion of uncompressed data from an application buffer that is to be input for compression to produce a compressed data stream. Other embodiments are described and claimed.

摘要： Methods, systems, and apparatuses are disclosed for signing and verifying data using multiple hash algorithms and digests in PKCS including, for example, retrieving, at the originating computing device, a message for signing at the originating computing device to yield a signature for the message; identifying multiple hashing algorithms to be supported by the signature; for each of the multiple hashing algorithms identified to be supported by the signature, hashing the message to yield multiple hashes of the message corresponding to the multiple hashing algorithms identified; constructing a single digest having therein each of the multiple hashes of the messages corresponding to the multiple hashing algorithms identified and further specifying the multiple hashing algorithms to be supported by the signature; applying a signing algorithm to the single digest using a private key of the originating computing device to yield the signature for the message; and distributing the message and the signature to receiving computing devices. Other related embodiments are disclosed.

摘要： A flexible aes instruction set for a general purpose processor is provided. The instruction set includes instructions to perform a “one round” pass for aes encryption or decryption and also includes instructions to perform key generation. An immediate may be used to indicate round number and key size for key generation for 128/192/256 bit keys. The flexible aes instruction set enables full use of pipelining capabilities because it does not require tracking of implicit registers.
