1. 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:

  • generating a plurality of decoy data signals along a plurality of separate communication channels;

    applying the plurality of decoy data signals and the at least one true data signal as parallel channel inputs to a scrambling unit, having an original set of parallel channel assignments;

    scrambling the original set of parallel channel assignments for sequential packets of both the at least one true data signal and the plurality of decoy data signals to form a plurality of scrambled signals using a predefined channel assignment scrambling key; and

    applying the plurality of scrambled signals to as separate, parallel inputs along a plurality of input channels to a multi-channel open-air transmitter; and

    transmitting the plurality of scrambled signals across an open-air communication system.
