Abstract: A method and system for secure processing of authentication key material in an ad hoc wireless network enables secure distribution of the authentication key material between a mesh authenticator (110) and a mesh key distributor (115), which may be separated by multiple wireless links. The method includes deriving a pairwise transient key for key distribution (PTK-KD) using a mesh key holder security information element (MKHSIE). A mesh authenticator pairwise master key (PMK-MA) is then requested using a first mesh encrypted key information element (MEKIE) that includes data origin information. Using the pairwise transient key for key distribution (PTK-KD), a second mesh encrypted key information element (MEKIE) is then decrypted to obtain the mesh authenticator pairwise master key (PMK-MA).

Abstract: A method of communication between a transmitter node and a receiver node in a multi-hop communication network (100), comprising: formatting information into a data structure to generate a mesh action frame (400), wherein the mesh action frame (400) comprises a header (420) comprising a source address (SA) that identifies such a node, a destination address (DA) that identifies a recipient node, a transmitter address (TA) that identifies a sender node, and a receiver address (RA) that identifies a receiver node; and a body field (430) comprising a mesh action data unit (434); and sending the mesh action action frame from the transmitter node.

Abstract: A method and apparatus for establishing security associations between nodes of an ad hoc wireless network includes two authentication steps: an initial first contact step (authentication, authorization, and accounting (AAA)-based authentication), and a "light-weight" step that reuses key material generated during first contact. A mesh authenticator within the network provides two roles. The first role is to implement an 802.1X port access entity (PAE), derive transient keys used for encryption with a supplicant mesh point via a four-way handshake and take care of back end communications with a key distributor. The second role is as a key distributor that implements a AAA-client and derives keys used to authenticate a mesh point during first contact or fast security association. The key distributor and the on-line authentication server can communicate to one another without these messages being transported over mesh links.

Abstract: The disclosure relates to techniques and technologies for efficiently transporting management information between mesh nodes across multiple hops or "mesh links" in a multi-hop mesh network. These techniques and technologies are general purpose and provide an extensible mechanism for transporting management traffic across a mesh network. These techniques and technologies can be applied in a number of applications relating, for example, to security, routing, radio measurements, mesh node management, etc.
