Abstract:
1. A method for deploying a trust bridge in an ad hoc wireless network, the method comprising: processing at a delegate certification authority (DCA) node device authorizations received from of a plurality of certification authorities (CAs) of different organizations, wherein the authorizations authorize the DCA node device to serve as a DCA representing the CAs; processing at the DCA node device context information received from the ad hoc wireless network; determining at the DCA node device, based on the context information, that a second node device should be enabled as a new trust bridge, wherein the trust bridge operates to provide interoperability for multi-organizational authentication; performing at the DCA node device a trust bridge deployment to enable the second node device to serve as the new trust bridge; wherein the trust bridge deployment comprises: authenticating the second node device at the DCA node device; determining at the DCA node device that the second node device has authenticated the DCA node device; determining at the DCA node device that the second node device is authorized to function as the trust bridge; transmitting a bridging certificate from the DCA node device to the second node device; and transmitting a DCA-authorizing certificate from the DCA node device to the second node device, whereby the second node device is authorized to function as the trust bridge in the ad hoc wireless network.
