    摘要: Protecting usage of key store content at a given user device of an end user includes receiving the key store content at the given user device. The key store content includes key materials encrypted using encryption credentials compatible with the given user device. The key store content is in a format compatible with the given user device. The encrypted key materials of the key store content are imported to a protected key store of the given user device, wherein all the key materials of the key store content are imported at one go. The key materials are stored at the protected key store in the encrypted form, and are non-exportable from the key store. Internally within the protected key store, one or more key store integrated services of the given user device are allowed to access the non-exportable key materials for use, via key references only.

    摘要: An encoder for encoding input data to generate corresponding encoded data is provided. The encoder (10) is operable to process a sequence of elements in the input data from a first element thereof to a last element thereof. The elements have corresponding symbols. The encoder is operable to compute probabilities of symbols present in the sequence, wherein the probabilities of the symbols are computed while disregarding those elements of the sequence that have already been encoded into the encoded data. Moreover, the probabilities of the symbols are adaptively changed as the sequence of elements is progressively encoded into the encoded data. Furthermore, information describing the probabilities is delivered; optionally, the probabilities of the symbols are accompanied with additional information indicating how the probabilities are adaptively changing. There is also provided a decoder for performing an inverse of encoding performed by the encoder.

    摘要: An encoder for encoding data to generate corresponding encoded data including information indicative of a frequency, probability or range of one or more symbols to be represented in the encoded data. The encoder can include in the encoded data additional information indicative of whether information indicative of a frequency, probability or range for at least one symbol amongst the one or more symbols is in the encoded data. The encoder can include in the encoded data the additional information of whether information indicative of a frequency, probability or range for at least one symbol amongst the one or more symbols in the encoded data expressed as single availability bit information. The encoder can represent inclusion of information indicative of the frequency, probability or range information by use of a single availability bit value “7”, and non-inclusion of information indicative of the frequency, probability or range information by use of a single availability bit value “0”.

    摘要: A decoder is operable to decode input data to generate corresponding decoded output data. The decoder includes data processing hardware which is operable to: (a) process the encoded input data to extract therefrom header information indicative of encoded data pertaining to individual blocks and/or packets included in the encoded input data, and information including data indicative of transformations employed to the individual blocks and/or packets; (b) create an initial set of individual blocks and/or packets based on received header data, and preparing a data field in a data storage arrangement for receiving decoded individual block and/or packet content; (c) split or combine individual blocks and/or packets in the data field according to information indicative of splitting/combining; (d) retrieve information describing the transformations and then applying an inverse of the transformations for decoding the encoded and compressed original block and/or packet data to generate corresponding decoded block and/or packet content for populating said data field; and (e) when the encoded input data has been at least partially decoded, outputting data from the data field as the decoded output data.

    摘要: A data communication system includes a centralized server arrangement coupled via a communication network arrangement to a plurality of client devices. The centralized server arrangement and the plurality of client devices exchange data. The system allocates the data into a primary type of data and at least a secondary type of data. The primary data is communicated substantially immediately within the system, and at least the secondary data is communicated in the system in association with corresponding acknowledgements (ACK) in response to receipt of the second type of data at one or more of the client devices. At least one of the one or more client devices is optionally a wireless-enabled mobile communication device or a wirelessly-connected personal computer (PC).

    摘要: A system for communicating data from a source device to a destination device where the source device has no direct access or has only restricted access to any data communication network. The system includes a network device that is to be coupled in communication with the source device, thereby enabling the source device to transfer to the network device the data to be communicated. The system also includes a network node configured to provide a network node service to a source client executing on the network device and to a destination client associated with the destination device. The network device is to be coupled in communication with the network node via a data communication network. The source client is configured to communicate the data to the destination device, by relaying the data through the network node service, when the destination client is connected to the network node service.

    摘要: An encoder generating encoded data. The encoder comprising an analysis unit for analysing portions of data to be encoded, and for directing the portions to one or more encoding units, the encoding units are operable to encode the data portions to generate encoded data. The one or more encoding units are operable to employ mutually different encoding algorithms when encoding the one or more portions. At least one encoding unit of the one or more encoding units is operable to compute data values present in each portion received thereat, to sub-divide the data values into at least two sets, to compute at least one aggregate value for a given set derived from the data values present in the given set. A corresponding decoder for decoding data generated by the encoder executes an inverse of encoding steps employed in the encoder.
