- Abstract
- A detailed threat model of the speech information confidentiality circulating on the informatization object with a fiber-optic communications was proposed which is associated with spurious acoustic modulation and crosstalk on optical streams in an optical cable. A danger of the implementation of a fiber optic channel of the speech information leakage is shown on the basis of a qualitative physical description of the processes of formation, transmission and recording of informative signals of acoustic and optical nature. Possible channel implementation schemes are described. It are identified places and it are made estimates for the size of the reconnaissance access zones, which can reach hundreds of kilometers. A possible generalized scenario of threat realization is also presented.
