The master node is further configured to adaptively account for hidden nodes with which the master node cannot bi-directionally directly communicate by communicating at least one signal with at least one proxy node. Other methods and network elements are disclosed.

摘要： System and method for providing secure communications is provided. Initially, an exchange protocol, such as a password-authenticated key exchange protocol, is used to create a shared secret. From the shared secret, two keys are created: a utilized key and a stored key. The utilized key is used to encrypt messages between nodes. When it is time to replace the utilized key to maintain security, the stored key is utilized to encrypt messages for generating/distributing a new shared secret. The new shared secret is then used to generate a new utilized key and a new stored key. This process may be repeated any number of times to maintain security.

摘要： One embodiment of the present invention relates to a network device. The network device includes a receiver configured to be coupled to a transmission medium supporting a multi-carrier channel over which data is communicated as symbols in a first communication state according to an initial bit-loading configuration. The receiver is further configured to detect noise that can corrupt the symbols on the multi-carrier channel. In addition, the receiver is configured to, in response to the detected noise, allocate at least part of the multi-carrier channel to a transient robust channel that facilitates adaptive communication. Other methods and devices are also disclosed.
