Abstract
A dual-mode communication device adapted for communication over a public network, wherein the dual-mode communication device is adapted to be operated in a normal mode and in an obfuscated mode. The dual-mode communication device includes a processor and a network interface device. The processor develops a frame from a payload received by the dual-communication device and, if the dual-mode communication device is operating in the obfuscated mode, an obfuscated frame from the frame. The frame and the obfuscated frame comprise a preamble that conforms with protocols associated with the public network and the processor. A network interface transmits one of the frame or the obfuscated frame using the public network. The payload may be extracted from the frame by any receiving device operating in the normal mode in the public network and the payload may be extracted from the obfuscated frame only by another communication device also operating in the obfuscated mode in the public network.
