Study of characteristics of the acousto-optic channel of speech information leakage in the conditions of implementation of protection mechanisms

Abstract: The dynamic characteristics of the processes of speech information transmission from the source to its recipient, as well as the interception of this information by an attacker through the acousto-optical leakage channel are determined. The authors formalized the probability of correctness of matching these characteristics at each stage of the change of the material carrier of the information speech signal when using the means of information protection from leakage through channels of the considered type.

Keywords: speech information, acousto-optical channel of speech information leakage, laser acoustic location system, electrical characteristics of the communication channel, matching conditions of signal characteristics, communication channel, correctness of matching, possibility of speech information leakage
