Abstract

A method and system for covert communication is provided by using a hybrid approach of pseudo-random noise (PN) sequencing with chaotic signals to make a transmitted waveform both hard to detect and hard to intercept by an unintended receiver. The method and system makes a covert communication system with chaotic signals practical for in-field use, including operation in a high noise power environment and allowing for easily changing between different security keys to maintain covertness.
