摘要： System architecture and corresponding method for securing communication via a network (e.g. IEEE 802.11) is provided. In accordance with one embodiment, the present system and method protocol, may be suitably configured to achieve mutual authentication by using a shared secret to establish a tunnel used to protect weaker authentication methods (e.g. user names and passwords). The shared secret, referred to in this embodiment as the protected access credential may be advantageously used to mutually authenticate a server and a peer upon securing a tunnel for communication via a network. The present system and method disclosed and claimed herein, in one aspect thereof, comprises the steps of 1) providing a communication implementation between a first and a second party; 2) provisioning a secure credential between the first and the second party; and 3) establishing a secure tunnel between the first and the second party using the secure credential.

摘要： A Wireless LAN Context Control Protocol (WLCCP) is used to establish and manage a wireless network topology and securely manages the "operational context" for mobile stations in a campus network. The WLCCP registration protocol can automatically create and delete links in the network, securely distribute operational context, and reliably establish Layer 2 forwarding paths on wireless links. A single infrastructure node is established as the central control point for each subnet, and enables APs and MNs to select the parent node that provides the "least-cost path" to a backbone LAN. Context messages provide a general-purpose transport for context and management information. WLCCP "Trace" messages facilitate network diagnostic tools. Ethernet or UDP/IP encapsulation can be used for WLCCP messages. Ethernet encapsulation is employed for intra-subnet (e.g. AP-to-AP or AP-to-SCM) WLCCP messages. IP encapsulation is used for inter-subnet WLCCP messages and may also be used for intra-subnet WLCCP messages.

摘要： A detection-based defense to a wireless network. Elements of the infrastructure, e.g., access points or scanning-only access points, detect intruders by detecting spoofed frames, such as from rogue access points. Access points include a signature, such as a message integrity check, with their management frames in a manner that enables neighboring access points to be able to validate the management frames, and to detect spoofed frames. When a neighboring access point receives a management frame, obtains a key for the access point sending the frame, and validates the management frame using the key.

摘要： A method and system for pre-authenticating a pre-establishing key management on a roaming device prior to reassociation to facilitate fast hand-off in a wireless network is described. For enhanced mobility, both authentication and key establishment is performed prior to reassociation of the roaming device between access points. When the roaming device enters in contact with one of the access points, a local authentication is performed between the access point and the roaming device prior to reassociation with the access point to allow for fast hand-offs of the device between access points within the network.

摘要： A method for multicast load balancing in a wireless network having a plurality of access points. The method includes setting a maximum Internet protocol multicast bandwidth for the access points, receiving an admissions control request from a client at one of the access points, and determining whether the admissions control request from the client is for an admitted or unadmitted multicast stream at the access point. The access point is responsive to the admissions control request for the admitted multicast stream by servicing the admitted multicast stream and to the admissions control request for the unadmitted multicast stream by servicing the unadmitted multicast stream where the bandwidth required for the unadmitted multicast stream, plus that portion of the access point bandwidth currently used for all existing downlink multicast streams, does not exceed the maximum internet protocol multicast bandwidth for the access point.

摘要： A method and apparatus for reassociation of a mobile node is described. The mobile node is associated with an access point coupled to a network. A new pairwise transient key is computed based on a pairwise transient key and a rekey request number derived from a previous association. A reassociation request is then sent including a mobile node identification, the rekey request number and an authentication element. A reassociation response is received. The reassociation response includes a response authentication element that comprises proof of possession of a group transient key and the new pairwise transient key. The reassociation response is then confirmed by verifying that the new pairwise transit key received in the reassociation response matches the computed new pairwise transient key.
