Abstract:
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 N decoy data signals along a plurality of separate communication channels, a value of N being at least equal to two and selected to be sufficient to suppress other uses of the multi-channel communication system; applying the plurality of N 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 N decoy data signals to form a plurality of scrambled signals using a predefined channel assignment scrambling key; and transmitting the plurality of scrambled signals across an open-air communication system.
