Embodiment Construction

[0041] The invention provides a covert channel communication method based on gyroscope resonance, comprising the following steps:

[0042] Step 1: Sound wave coding: The communication frequency is determined by the resonance characteristics of the gyroscope in the target receiving device. Based on the idea of ​​pulse interval coding and the coding method is adjusted, the signal is modulated on the target frequency band and played by the speaker.

[0043] Step 2: Channel noise elimination: including frequency drift and random error elimination. Based on the inter-axis characteristics of the gyroscope when it resonates, the data on two axes are selected to form a joint channel through a multiplier and an average filter to eliminate the frequency drift and gyroscope random error caused by the gyroscope sampling rate drift.

[0044] Step 3: Decoding: Use the loudest threshold algorithm to delineate the threshold and decode it to obtain the data transmitted in the channel.

Abstract

The invention discloses a covert channel communication method based on gyroscope resonance. The method establishes a communication channel from a loudspeaker to a gyroscope, discovers the inter-axis characteristics of the gyroscope resonance for the first time, and realizes channel noise and motion interference based on this method. Elimination, a motion-robust covert channel communication method across protocols, and the first motion-robust based motion sensor reuse system. The present invention uses low-cost speakers and gyroscopes to realize cross-protocol Internet of Things communication without additional peripherals, without physical contact or fixed position requirements, and can achieve high communication speed and accuracy, and supports multi-channel / Simultaneous transmission of multiple users meets convenience and practicality at the same time.

Description
