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.

Abstract
A method and apparatus that uses the dynamics of chaotic systems for the remote generation of a digital key, for use in any encryption algorithm. After initialization, the dynamics of a chaotic system are allowed to generate the 0 and 1 bits of a key bitstream. An initialization bitstream is transmitted, using conventional transmission technologies, to an identical chaotic system. This chaotic system is driven into synchrony and allowed to generate a key bitstream, which is identical to the other bitstream because the chaotic systems have been synchronized.

6. A system for remote digital key generation, comprising:
-
an encryptor for applying an initialization code having a first chaotic system such that the initialization code causes the first chaotic system to assume a periodic orbit system 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 bitstream, and for sending the initialization code to a decryptor; and the decryptor for applying 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. - View Dependent Claims (7, 8, 9, 10, 12, 15, 16)
