The objectified procedure and a technology for assessing the state of complex noise speech information protection

Abstract: Зазвичай при побудові систем захисту мовної інформації для систем постановки активної завади використовують генератори білого шуму. Визначення рівня захищеності мовної інформації від витоку акустичними та вібраційними каналами відбувається за відповідними нормативними методом та технологією. Але використання зловмисником багатоканальних методів перехоплення мовної інформації та сучасних методів обробки цифрових фонограм (вейвлет-перетворення, кореляційного аналізу та інше) дозволяє отримати несанкціонований до… Show more

“…Such clearing methods can include, first of all, wavelet-transformation, phonetic-correlation analysis, adaptive and neuro network filtration. This leads, as shown in paper [14], to a significant increase in the level of speech signal recognition and, accordingly, to a critical increase in the values of such indices as SII, W (WII), AI (AI), SPC, SNR and SNRuni32.…”

“…However, as analysis [9][10][11] shows, the use of «white» noise and its clones has a significant drawback -the use of modern systems for digital processing of phonograms can significantly reduce the level of noise interference in the phonogram. And in [12][13][14] methods of digital processing of digital phonograms, including wavelet transform and correlation analysis, are presented. The informational composition of the intercepted message is substantially restored by the use by an attacker of multi-point «removal» of information from structural elements [15,16] -this is possible, since several emitters connected to the same channel are used in SSAVAN.…”
