1. A method of remote digital key generation, comprising:

  • applying an initialization code to a first chaotic system such that the initialization code causes the first chaotic system to assume a periodic orbit independent from the initial state of the first chaotic system;

    allowing the first chaotic system to generate, at least in part based on the periodic orbit, a first key bitstreamapplying the initialization code to a remote second chaotic system, identical to the first chaotic system, to drive the second chaotic system into synchrony with the first chaotic system independent from the initial state of the second chaotic system, thereby allowing the second chaotic system to reproduce the first key bitstream.
