ASSESSMENT CRITERIA OF VOICE SIGNAL LEAKAGE PROTECTION
Abstract
A method of assessing of normative protection indicator of speech signal by the criterion of speech intelligibility at high noise level in the band of speech signal, equal to intelligibility, by means of complex measuring signal with a large base, is substaniated. The advantage of the complex measuring signal with a large base over harmonic measuring signal when assessing protection of speech data leakage channels is shown. Voice signals in digital form along with voice signals in analog form are widely used. It is necessary to find mathematical relation between bit-error probability and speech intelligibility for voice signals in digital form. It is also necessary to establish mathematical relation between compound signal with large base and harmonic measuring signal. The main purpose of the study is to establish a normative characteristic of leakage protection of voice signals on the base of determined mathematical relations. The given mathematical relations will allow realizing the automated measuring system for estimation of security of the confidential information transformed into the analog and digital form, in channels of its leak.
