Abstract:
A secure communication hub for routing communications among local user radio equipment, and securely routing communications with a remote command center using a satellite communication system, the secure communication hub comprising:a plurality of radio interface units, each for communicating with select ones of the local user radio equipment, wherein at least some of the radio interface units communicate with the local radio equipment using a low-probability of detection format;a router coupled with each radio interface unit;a format converter coupled to the router;a satellite transceiver for communicating with satellites of the satellite communication system;data encryption/decryption circuitry coupled between the satellite transceiver and the router for providing encrypted data packets to the satellite transceiver and providing decrypted data packets to the router;a routing controller coupled to the router for controlling routing of communications among the plurality of radio interface units, and routing communications between the satellite transceiver and the radio interface units,wherein when data destined for the remote command center is received from one of the local user radio equipment, the format converter performs a format conversion on said data to create packetized data suitable for said satellite communication system, the routing controller adds routing instructions to said data to identify said command center as a destination for said data, the data encryption/decryption circuitry encrypts said data on per-packet basis, and the satellite transceiver transmits said data in packetized form for routing through the satellite communication system to the command center.
