  • Patent number: 9400892
    Abstract: A secure integrated circuit (IC) to provide access to an electronic storage, the secure IC including a memory and a processor. The processor may generate a first key and a second key, and enable storing the first key in the memory and storing the second key in a device memory of a device. The processor may then receive the second key from the device when the device wants to access the electronic storage, and grant the device access to the electronic storage by using the first key and the second key received from the device.
    Type: Grant

    Date of Patent: July 26, 2016
    Assignee: Broadcom Corporation
    Inventors: Yasantha Rajakarunanayake, William Bunch, Jacob Mendel
  • Patent number: 9202070
    Abstract: Disclosed are various embodiments providing a portable wireless communication device that includes a secure element configured to route a set of input/output (I/O) channels to host processing circuitry of a mobile communication device. The secure element includes an application executable by the secure element, the application being configured to obtain a policy via an I/O channel of the set of I/O channels. The application is further configured to prevent the host processing circuitry from accessing data corresponding to at least a portion of the set of I/O channels according to the policy.

  • Publication number: 20150006897
    Abstract: A host apparatus to obtain electronic authentication of a request associated with a group, the host apparatus including a processor to receive the request from an external device external to the group, to generate a digital document based on information associated with the request, to transmit the digital document to a trusted entity device for electronic authentication of the request, to receive the digital document from the trusted entity device, to determine whether the electronic authentication of the request was successful, and to process the request when it is determined that the electronic authentication of the request was successful.

  • Patent number: 6198722
    Abstract: A method is shown for a central node to flow control one or more end stations operating under a medium access control protocol wherein the central node transmits a signal to the end stations that causes the end stations to defer a data transmission, and wherein the central node halts the transmission to reset a protocol timer in the end stations, and wherein the central node resumes transmission before expiration of another protocol timer that would cause the end stations to commit to attempting a data transmission onto the communications medium and the end stations can thereby be held in a flow control state without loss of transmission packets.
