- Abstract
- Formation model of information security threats against leakage through technical channels is determined by the physical characteristics of the informative signal as it travels from the source to the offender. Based on analogy of leakage channel with systems of information transmission and measuring systems is proposed a system of physical assessments, which allows you to effectively characterize and make a comparison between different leakage channels. As an leakage channel estimates is supposed to use efficiency, noise, modulation, sensitivity coefficients, that are simple physical interpretation and easily calculated. Entered parameters are used for assessing the effectiveness of speech leakage channel through the fiber optic communication, which shows a high risk of this type of leakage to ensure the information security of the object.
