  • Secure method of termination of service notification
    Patent number: 8086858
    Abstract: A method for notifying a client device of termination of at least one service provided to the client device by a server system within an enterprise network is disclosed. The method includes the step of establishing authentication data and notification data, where the authentication data is related to the notification data, and sending the authentication data to the client device for storage during a provisioning operation. When the server system identifies a termination of service, it sends the notification data to the client device, which may then authenticate the received notification data using the authentication data.

  • Memory controller interface
    Patent number: 8086788
    Abstract: A memory interface controller and method to allow a processor designed and configured to operate with NOR flash and static random access memory SRAM devices to instead operate using NAND flash and synchronous dynamic random access memory SDRAM. The system accomplishes this by caching sectors out of NAND flash into SDRAM, where the data can be randomly accessed by the processor as though it were accessing data from NOR flash/SRAM. Sectors containing data required by the processor are read out of NAND flash and written into SDRAM, where the data can be randomly accessed by the processor.

  • Call forwarding methods and apparatus for mobile communication devices which operate in WWANS and WLANS
    Patent number: 8085742
    Abstract: Methods and apparatus for use by a mobile communication device in facilitating voice calls through a wireless local area network (WLAN) and a wireless wide area network (WWAN) are disclosed. When switching communication operations from a WLAN coverage region of the WLAN to a WWAN coverage region of the WWAN, the mobile device causes a message for forwarding voice calls to a WWAN identification number of the mobile device to be transmitted through the WLAN. The mobile device subsequently causes a message for cancelling the forwarding of voice calls to a WLAN identification number of the mobile device to be transmitted through the WWAN. When switching communication operations from the WWAN coverage region of the WWAN to the WLAN coverage region of the WLAN, the mobile device causes a message for forwarding voice calls to the WLAN identification number of the mobile device to be transmitted through the WWAN.

  • System and Method for Uplink Control Information Transmission in Carrier Aggregation
    Publication number: 20110310986
    Abstract: A method for communicating uplink control information to a base station using a user equipment is presented. The method includes identifying component carriers on the user equipment scheduled for Physical Uplink Shared CHannel (PUSCH) transmissions, and identifying at least one first ranking for each of the component carriers for transmission of uplink control information. Each first ranking is at least partially determined by whether the component carrier is configured for delay-sensitive transmissions. The method includes using the at least one first ranking to select a first component carrier for transmission of uplink control information, and encoding uplink control information into the first component carrier for transmission to the base station.

  • POWER ANALYSIS ATTACK COUNTERMEASURE FOR THE ECDSA
    Publication number: 20110314292
    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.
