Abstract:
1. A method for providing fast secure handoff in a wireless mesh network, comprising: configuring a plurality of access points as first level key holders (R0KHs) within a radio access network to which one or more supplicants within the wireless mesh network are capable of establishing a security association; configuring a common mobility domain identifier within the configured plurality of first level key holders access points of a mobility domain; propagating identity of a first level key holder access point and the mobility domain identifier of the mobility domain through the wireless mesh network to enable the one or more supplicants within the mobility domain to perform fast secure handoff; recording one of the configured plurality of first level key holder access point of the mobility domain as a “root” first level key holder when the one or more supplicant initially establishes security association with the mobility domain; recording one of the configured plurality of first level key holder access point as a “current” first level key holder when the one or more supplicant has already established a security association within the mobility domain; and determining whether the “current” first level key holder access point in the mobility domain has failed and
