Abstract

The method for secure information transmission via chaotic sequences with modulated parameters is studied. Information decoding in this method implies solution of the inverse problem of chaotic dynamics, as suggested by Anishchenko et al (1998, 1999). Algorithms for reconstruction of information parameters in single-channel and multiple-channel schemes of data transmission are discussed and requirements for map, generating chaotic sequence are formulated. The method under consideration impedes unauthorized access to the information transmitted and may serve as flexible instrument for multipurpose cryptographic applications.
