A secure, open-air communication system utilizes a plurality of “decoy” data signals to hide one or more true data signals. The true data signal(s) are channel hopped with the plurality of decoy data signals to form a multi-channel “scrambled” output signal that is thereafter transmitted in an open-air communication system. The greater the number of decoy signals, the greater the security provided to the open-air system. Further security may be provided by encrypting both the true and decoy signals prior to scrambling and/or by utilizing a spatially diverse set of transmitters and receivers. Without the knowledge of the channel assignment(s) for the true signal(s), an eavesdropper may be able to intercept (and, with time, perhaps descramble) the open-air transmitted signals, will not be able to distinguish the true data from the decoys without also knowing the channel assignment(s).
A method of providing secure, open-air transmission of at least one true data signal in a multi-channel communication system, the method comprising the steps of:
A method of recovering at least one true data signal from a plurality of open-air scrambled signals received in a multi-channel communication system, the method comprising the steps of:
An open-air communication system including a multi-channel, secure open-air transmitter for simultaneously communicating at least one true data signal and a plurality of decoy data signals, the transmitter comprising
A secure, open-air communication system including
