Novel method of chaotic communication proposed by physicists

Two Taiwanese physicists have invented a new method of chaotic communication that has proved better than the conventional ones in terms of fending off intrusions and external noise, academic sources reported Thursday.
The duo, both of whom are research fellows at Academia Sinica's Institute of Physics, uses the message carriers themselves as binary codes rather than hiding the message in the carrier, to achieve higher transmission security, according to a press release from Taiwan's top research institute.
On the receiver side, according to the press release, the user can analyze the code-embedded carriers to decrypt the message by using temporal transfer entropy, a new technology developed by Hu Chin- kun and Hung Yao-chen.
Hu explained that chaotic communications usually involve interweaving a weak message into a strong chaotic carrier -- protecting the message with the help of the carrier's randomness and disorderliness.
However, the method has become antiquated since the realization of time-series analysis, Hu continued, adding that the development necessitates a more secure communication method, such as nonlinear encryption.
In addition to use in communications, Hu went on, temporal transfer entropy can also be applied to many different scientific fields, such as neurophysiology, economics and climatology.
Their research paper on the topic -- titled Chaotic Communication via Temporal Transfer Entropy -- has been published in the Dec. 12 issue of Physical Review Letters, a leading international physics journal.
