- Abstract
- Technical channel acoustical (speech) information leakage based on the parasitic acoustooptic modulation and crosstalk in fiber optic network elements is a new little-studied threats to information security on the object. The research of functioning channel leakage shows high efficiency by interception near the fiber optic cable systems. Efficiency is influenced by a wide range of factors, including the optical scheme probing, parameters of probing optical radiation, characteristics of the registration system, and informative signal processing techniques. On the basis of the experimental data can be offered protection methods of speech information near the regular fiber optic communication systems against information leakage.
