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 the error of deciphering in the model of cryptosystem based on NRI? It appears that this error can be submitted as a wave process. The analytical experessions for amplitude and phase of this process are obtained. These expressions do not contradict results of author's computing experiments. Obtained results allow to estimate power of keys set as quality criterion of antiwiretap enciphering.
