Paper Abstract

This article presents the single photon fiber optic sensor for detecting interferences of the transmission line. With the growing popularity of the use of fiber optic communication systems, there is a need to protect transmission lines against unauthorized interference and data interception. Classical Quantum Key Distribution (QKD) allows to transfer quantum key and interrupt transmission when it detects interference. The use of proven as safe protocols BB84 in conjunction with currently used encryption techniques provide better data safety. However, due to lack of evidence on the safety of transmission using commercial QKD systems, their apply to the protection of classified information is currently impossible. Support these assumptions are carried out so far successful attacks on QKD systems. These statements do not mean impossibility of implementing these systems for the protection of classified information in the future. Our team proposes a solution consisting in transmitting information in fiber optic track with simultaneous implementation of a single photon sensor, developmentally impaired with the location of the interference place. The greatest yield of this method is to detect the intruder, who is unaware of its detection. To optimize and accelerate the testing, a simulation program that allows you to adjust the operating parameters of the sensor system and verification of performance of laboratory systems has been developed. Execution of simulation, helps in the selection of appropriate elements of the actual configuration and in comparison to obtained results. This work contains the results of the test operation of the system for disorders of mechanical and manual as well as performed simulations.
