Paper Abstract

The possibility of use of nonlinear ring interferometer (NRI) for protect of information was shown by the authors earlier. How does the mismatch of the principal physical factors influence error of deciphering in model of cryptosystme based on NRI? It appears that this error can be submitted as a wave process. The anlysistical expressions of amplitude and phase of this process are obtained. These expressions do not contradict results of author's simulations. A possibility of delay time cracking by means of correlation analysis and number of keys of stipulated by nonlinearity parameter variations is discussed.
