  • Method and apparatus for providing an interface for a messaging mailbox
    Patent number: 8055799
    Abstract: A method and apparatus for accessing messages from a message server. Messages are stored on the message server in their current format without transcoding. When a client opens a session with the message server, a data transfer rate is determined for the client. In response to a message retrieve request, the bit rate of the message is compared to the data transfer rate, and if less than the data transfer rate, the message is downloaded to the user terminal without transcoding. If the bit rate is greater than the data transfer rate, then the message is transcoded to a lower bit rate according to a codec supported by the user. The codec may be selected from a set of codecs supported by the user terminal. The user is provided with the capability to override the system selected codec, for example, to pick a codec for secure encoding or encryption.

  • Method and system for incremental patching of binary files
    Patent number: 8055096
    Abstract: An incremental patch is generated as a set of delta files or sector-specific patches, intended to be applied incrementally to an old binary image. Each sector-sized patch takes into account changes to the binary image made by previous patches in the series, such that cyclic dependencies are eliminated. The sector-sized patches are generated by applying a binary difference algorithm to the then-current partially patched image, until each sector has a corresponding delta file. The order for patching sectors may be determined by selecting sectors for patching based on first overwriting those sectors making the least contribution of data to generation of the new binary image.

  • Power analysis attack countermeasure for the ECDSA
    Patent number: 8027466
    Abstract: Execution of the Elliptic Curve Digital Signature Algorithm (ECDSA) requires determination of a signature, which determination involves arithmetic operations. Some of the arithmetic operations employ a long term cryptographic key. It is the execution of these arithmetic operations that can make the execution of the ECDSA vulnerable to a power analysis attack. In particular, an attacker using a power analysis attack may determine the long term cryptographic key. By modifying the sequence of operations involved in the determination of the signature and the inputs to those operations, power analysis attacks may no longer be applied to determine the long term cryptographic key.

  • Method and system for identifying degradation of a media service
    Patent number: 7986626
    Abstract: A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.
