Загрози витоку акустичної інформації через волоконно-оптичні системи зв’язку

Abstract

Fiber optic communication systems (FOCS) are widely used due to their high bandwidth, immunity to electromagnetic interference, and advanced security features. However, they are not completely protected from information leak age. One of the new threats is acoustic information leakage, which can occur due to external acoustic vibrations affecting the optical fiber. The paper considers the main mechanisms of such leakage, possible interception methods, and possible countermeasures.
