Abstract

Laser chaotic system is used to complete private communication experiment in this paper. In the process of private communication, both chaotic laser beam and electric chaos signal which contain private signals are transferred to the place where the signals is received. Two same non-linear electric circuits with same response behavior are used in the experiment setup to change frequencies and waves of laser chaotic signal and electrical chaotic signal at the same time. Even if both laser chaotic signal and electric signal are lost, transferred private signals are still safe.
