Encryption/identification using array of resonators at transmitter and receiver

A method, comprising:

• receiving, at a receiver, a waveform from a sender;
• exciting at least some individual ones of a plurality of oscillators of an array of coupled oscillators with at least one signal comprising first information that comprises a first key known to the sender and to the receiver, said array of coupled oscillators representing second information that comprises a second key known to the sender and to the receiver;
• generating a waveform that comprises signals output from the at least some individual ones of the coupled oscillators;
• and
• comparing the generated waveform to the received waveform.

An apparatus, comprising:

• means for generating a time evolution of frequencies output from at least some of a plurality of globally coupled oscillators;
• means for exciting at least some individual ones of the plurality of oscillators with a signal comprising first information that comprises a first key known to a sender and to a receiver, said generating means representing second information that comprises a second key known to the sender and to the receiver;
• means for outputting a waveform that comprises frequency signals from at least some individual ones of the plurality of oscillators, the generated waveform exhibiting chaotic behavior;
• and
• means for sending the waveform from the sender to the receiver.
