Hyperchaos neural network hiding secret communication circuit

Abstract

The invention discloses a hyperchaos neural network hiding secret communication circuit which is belongs to the technical field of communication. The circuit comprises a drive circuit and a response circuit, which are respectively a hyperchaos neural network circuit. A plaintext signal u(t) is superposed with a hyperchaos signal x(t) generated by the drive circuit, thereby generating a superposed signal x(t)+u(t). A password signal m(t) is obtained through encryption based on the conventional cryptography, is transmitted to the response signal through a transmission channel, and then is decrypted, thereby obtaining a superposed signal x(t)+u(t). The superposes signal is used for driving the response circuit, thereby obtaining a corresponding synchronization signal y(t). Finally, the superposed signal x(t)+u(t) is subtracted by y(t), thereby obtaining a password signal v(t). Compared with a conventional circuit, a hiding neural network is a hyperchaos neural network, thereby enabling a system to be more unpredictable, and improving the communication security.
