  • Patent number: 8924486
    Abstract: The present invention provides for method, system, and apparatus for facilitating communication between a first set of networked devices, such as client devices, and a second networked device, such as a server. A query message is transmitted from a representative device of the first set of networked devices, to the second networked device. The representative device may be selected in several ways. A response message may be transmitted from the second networked device, the message comprising an indication of devices from the first set of networked devices for which communications are pending. The response message is processed and devices identified in the response message are notified.

  • Patent number: 8438391
    Abstract: Systems and methods are described for establishing credentials at a device and at a device management server for the purpose of exchanging secure credentials in order to mutually authenticate the device and the server. A credential generation algorithm is described which uses a plurality of seeds, including the hardware identity of the device, the server identity, and a shared private key, to generate two sets of credentials, one to be used by the device and the other to be used by the device management server. The credentials are exchanged between the device and the server during any session, thereby assuring mutual authentication.
