Abstract

The embodiment of the present application provides a physical layer information hiding method, device, and terminal based on distance information estimation, which are used for signal transmission in a communication system monitored by a monitored end. The communication system includes a signal transmitting end and a signal receiving end. The method includes the following steps: obtaining distance value information between the monitoring terminal and the signal transmitting terminal; obtaining the average signal-to-noise ratio γ of the monitoring terminal according to the distance value information e ; According to the average signal-to-noise ratio γ e Obtain optimal embedding rate Rs, wherein Rs=LR / L, this L is the length of each carrier signal, and LR is the length of the secret signal embedded in each carrier signal; according to the optimal embedding rate Rs in the carrier signal Upload a secret signal of corresponding length for transmission.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method, device, storage medium and terminal for concealed data transmission based on distance information estimation. Background technique [0002] With the development of information society, information plays a pivotal role in modern society, but the hidden dangers of information security that appear along with it make information security research imminent. Information hiding technology is an important research branch in the field of information security research. It relies on cryptography, signal and image processing, computer science and other related disciplines, and has achieved rapid development in recent years. Information hiding technology mainly studies how to hide secret information on a public carrier signal and send it to the target receiver without arousing the suspicion of the listener, so as to realize the safe exchange of secret informatio...
