Abstract: In one preferred embodiment, a set of air interface protocols (AIPs) provides a method for secure wireless-to-IP communication between conveyance-mounted security sensors and one or more remote data consolidation centers employing a global ad-hoc network topology, comprising one or more on-conveyance sensing devices; one or more on-conveyance wireless communications devices; one or more wireless-to-IP bridging devices; one or more internet-addressable remote data centers; wherein the remote data center contains computer instructions for: commanding secure AIP-compliant operations; and maintaining a data base of security sensor-related events interfacing to an encryption key management facility.
