Recognition and Elimination of Anomalies in Information Leakage Channels in Opto-Ultrasonic Communication Channels in Data Streams of Industrial Automated Systems

The problem of detecting, recognizing and predicting anomalies has appeared relatively recently. However, when solving this issue, a number of difficulties arise, mainly associated with the need to take into account and detect previously unknown types of attacks and impacts. The resolution of this issue immediately attracted the attention of specialists in the areas of network security and information and industrial systems. Consequently, the existing solutions to some of the simplest particular cases of solving the issue of recognizing anomalies in computational processes did not allow the development of some unified, comprehensive method for detecting previously unknown types of attacks and influences. To address this issue, Western and Russian research teams and schools urgently engaged in in-depth abstract study of this issue. The detection of anomalies in dynamic information flows largely determines the effectiveness of information security management of computer networks in information and industrial systems. At the same time, the technology for predicting dynamic flows, data plays a major role in the concept of anomaly detection systems in the protection of information of various APCS. The creation of each automated system is based on the future capabilities of computer technology, advances in control theory, mathematical modeling and optimization methods. It is proposed to use the technology of opto-ultrasonic transmission and reception of information. Under ultrasonic ultrasonic waves (acoustic signals). The main source of acoustic signals are electromechanical ultrasonic vibrating systems. In this work, information leakage through a technical opto-ultrasonic channel is understood as the uncontrolled use of information from the protected information carrier through the physical medium to a technical means that intercepts information. Depending on the physical nature of the occurrence of information signals, the medium of their propagation, the technical channels of ultrasonic information leakage can be divided into acousto-vibration (vibration), acousto-optic (laser), acoustoelectric and acoustoelectromagnetic (parametric). Within the framework of this article, acousto-optic (laser) technologies are investigated.
