Abstract
A method and logic encoded in tangible media and apparatus for securing links between a mesh point and one or more identities of one or more parent mesh points of a wireless mesh network in order to secure the links. A first association is carried out to one of the identities of one of the parent mesh points. The first mesh point undergoes a mutual authentication with an authenticator and announces the possibility of multiple links and/or multiple paths. The authentication generates a first master key from which the root master key of the key hierarchy is derived so that other master keys for different identities are derivable using a hierarchy. The mesh point undergoes a 4-way handshake to derive a first transient key. Other transient keys are obtained by a fast roaming method without having to re-undergo a backend authentication, the other transient keys being for other links and/or paths and derived using the hierarchy.
