Abstract

Methods for determining a normalized information protection index, which is an entropic information index related to the digital information interception channel capacity, are presented. It is demonstrated that the normalized information index depends on the monitored energy indices for various types of signals and digital information transmission methods.

USING OF SINGLE-QUANTUM REGISTRATION FOR CONFIDENTIAL INFORMATION TRANSMISSION SYSTEMS OVER FIBER-OPTIC COMMUNICATION LINES

Иван Романович Гулаков, A. O. Zenevich, A. M. Timofeev +1 more

The system for transmission and reception of confidential information over fiber-optic communication line on the basis of created single-quantum registration system of optical radiation has 43 been suggested. With regard to such a communication system two types of optical wavelengths have been experimentally justified. One type of optical wavelength is used for information transfer and the second one for time synchronization of information transmission and reception, as well as for detection of unauthorized access to information, created with optical fiber macrobends. Optimal values of optical power, which allowed to provide the highest confidential information data rate and detect more effectively possible data loss channels have been established.

Analysis of Existing Methods for Enduring the Protection of Information in Fiber-optic Communication Lines

Madiyar MUSAGAZHINOV, Ali Mekhtiyev, Alexey V. Yurchenko

The problem of protection against unauthorised access to data is considered and the results of comparing existing methods of extracting data from optical fibreare presented, the possibility to develop algorithms and identification principles that would help control information leakage channels in fibre-optic transmission systems. Developments to solve the problem of information security, in two directions are described. The classification of methods of obtaining information, the physical principles of formation of leakage channels, as well as the methodology for transmitting the proportion of optical radiation outside the propagation environment, as well as the structure, principles of operation, and trends in the development of monitoring systems are presented. Both the advantages and limitations of methods are described. Information is given about the proposed analysis system based on a neural network for more accurate detection of unauthorised connection to the network.

The use of passive optical devices for the protection of information in fiber-optic communication lines and networks

Oleksandr Manko, О. С. Шматок, Андрій Борисович Петренко

Every year increases the amount of confidential information that is transmitted in optical communication networks. To ensure safe transmission of confidential information fiber optic lines are the most suitable. It is determined that the electromagnetic field of the light wave does not go beyond the optical fiber. However, under certain circumstances, interception of optical signal on the bend of the fibers is entirely possible. Thus, for the creation of optical lines with high level of information security are necessary additional measures. To this aim, in the proposed use of masking optical linear code by increasing the numbers of units are used passive components such as optical delay lines and optical splitters. The method allow increasing the number of units of code combinations to be transferred, and thus make it impossible for an adequate interpretation of the information. The advantage of the method is that the protection device is completely passive, and therefore reliable, and can be connected directly to the input and output of optical linear tract. Moreover, these devices do not require adjustment.

Methods of data protection for quantum secure communication system

Stanislaw Andrzej Rajba, Łukasz Więcław, Сергій Ніколаєнко +1 more

In this paper the methods of data protection for developed by authors earlier multichannel system of quantum secure communication are proposed. These methods allow closing the intercepted data from the unauthorized user. The simulation model of quantum secure communication system on optical fiber is developed. This model depends on three parameters: probabilities of an error in the fiber optic channel, time of detection of unauthorized connection to the fiber optic line and transmission rate. Results of modeling for two methods of data protection are presented.
