DATA SECURITY OUT OF THE CONTROL ZONE IN FIBER-OPTIC TRANSMISSION SYSTEMS

V. V. Shubin
VANT. Ser.: Mat. Mod. Fiz. Proc 2022. Вып.4. С. 72-87.

The paper considers the approaches to provide data security out of the control zone in fiber-optic transmission systems. The classification of networks is given and three ways to protect them are described: conventional and quantum cryptography and the use of technical means. The specific features of fiber-optic systems are considered: rarefied and dense wave division multiplexing, phase manipulation, forward error correction, and multitasking functionality. The conventional and quantum cryptography are described from the viewpoint of their correspondence to modern fiber-optic systems and data transmission security. The RFNC-VNIIEF approach to providing the transmitted data security in fiber-optic networks with the use of technical means is presented and these technical means are compared with other versions.

Keywords: data security, control zone, fiber-optic transmission system, conventional and quantum cryptography, technical information protection.
