    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: Systems and methods provide a mechanism for wireless stations and access points to negotiate security parameters for protecting management frames. The access point and station determine which management frames they are capable of and desire to protect. Data indicating protected frames are then exchanged between the station and access point to select which management frames are to be protected and a protection mechanism to be used for protecting the management frames.

    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.
