- Abstract
In order to further enhance the security of railway video information transmission on optical fi ber lines, combined with the structure of the railway integrated video monitoring system, the use of quantum communication technology to encrypt and transmit railway video sensitive information is studied, and the railway video monitoring quantum networking scheme is proposed for the first time. Aiming at the problems of long-distance transmission of quantum signals and optical fi ber loss encountered in the scheme, two key technology solutions of trusted relay and wavelength division multiplexing co-fiber transmission are respectively proposed, so that the quantum communication networking scheme has a certain feasibility and practical signifi cance.
