Abstract:

In order to further enhance the security of railway video information transmission on optical fiber 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 fiber 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 significance.

Key words: railway video monitoring, quantum communication, trusted relay, common co-fiber transmission
