    摘要: A technique for allowing client-driven profile updates in a wireless network uses a shared character password and a shared image that is known by both a client device and a network server. In some embodiments, a random character table is generated by a client device and is used, along with the shared character password and shared image, to calculate a one-time password (OTP). The OTP is then used to both encrypt and sign a new security profile to be delivered to the network server in a profile update request. The server may then generate the same OTP using information within the request and the shared character password and shared image. The new profile may then be decrypted and validated within the server.

    摘要: An energy efficient multi-core computing device and method are disclosed. According to embodiments of the invention, the processing load on a multi-core computing device may be monitored to determine whether one or more cores on the device may be dynamically shut down. Conversely, any core that is shut down may be dynamically powered up if the processing load on the device increases. Embodiments of the present invention therefore provide significant energy savings on multi-core platforms by minimizing the active cores on the device without affecting the device's processing capabilities.

    摘要: A method of authenticating a device's access to a communications node is disclosed. The method of operation includes the communications node generating a first value for use in the derivation of a first encryption key, the first encryption key being at least partially used to authenticate the device's access to the communications node in a first communications exchange. The method of operation includes the communications node modifying the first value, independent of the device, to create a second value. The method includes the communications node using the second value in authenticating the device's access to the communications node in a second communications exchange. Embodiments of the present invention include but are not limited to communications nodes and devices, subsystems, and systems equipped to operate in the above-described manner.
