摘要
Claims We claim: 1. A method of security authentication and key management within an inftastructure-based wireless multi-hop network, the method comprising: initially authenticating a supplicant including determining one or more authenticated supplicant role attributes with an authentication server; obtaining one or more authorization attributes from the authentication server by a top level key holder; determining whether the authenticated supplicant role attribute is a level one key holder by the top level key holder; initiating a four-way handshaking between the top level key holder and the supplicant with a pair-wise master key (PMK)_0 to derive a Key Distribution Key (KDK) when the authenticated supplicant role attribute is a level one key holder; and when the authenticated supplicant role attribute is not a level one key holder: communicating a level one pair-wise master key (PMK)_1 from the top level key holder to a level one key holder, initiating a four-way handshaking between the level one key holder and the supplicant with the level one pair-wise master key (PMK)1 to generate a secure communication link between the supplicant and the level one key holder, and communicating on the secure link between the level one key holder and the supplicant.
