Abstract
A sender and a receiver includes first and second arrays of coupled oscillators, respectively, that are substantially identically constructed so as to exhibit substantially the same dynamical response to excitation. A chaotic waveform generated at the sender is transmitted to the receiver, which generates a second chaotic waveform, and compares the received waveform with the generated second waveform. If the first and second waveforms match the sender is an authorized sender. An integrated circuit includes an array of coupled oscillators that in combination generate a waveform in response to at least one excitation signal. The array of coupled oscillators represents, in response to application of the excitation signals, a multi-dimensional security key that is shared between the sender of the waveform and the receiver of the waveform.
