WAYS OF INCREASING THE RELIABILITY OF MESSAGE TRANSMISSION IN INFORMATION AND COMMUNICATION SYSTEMS USING ONE-WAY RADIO CHANNELS

Abstract

Modern information and communication systems which use one-way radio channels have the main task to maximize the reliability and information transmission stealth. This task becomes more relevant in conditions of the radio-electronic warfare and growing of the cyber incidents with wireless vulnerabilities exploitation. This solution is useful for Internet of Things technologies with one-way interaction protocols and unmanned aerial vehicle control systems for organization and critical infrastructure cyber security support.The purpose of this work is the fading of possible ways for increasing of the message transmission reliability in the information and communication systems with one-way radio channels.The examples of digital modulation methods applications, interference-resistant coding which are used in modern information and communication technologies with one-way radio transmission are considered in the article. In the work were received results of digital modulation methods and interference-resistant coding analysis with minimum bit error rate criterion. The usage futures of combined random coding which is based on interference-resistant and stochastic coding combination were researched.Standard random bit generators were tested by the NIST Statistical Test Suite 2.1.2 application.This research results give us the possibility to increase the reliability of message transmission by way using binary phase-shift keying in combination with majority coding. In this case we should solve tasks to improve the phase estimation schemes of received signal and optimal choice of majority coding redundancy.In order to increase the reliability and information stealth of message transmission the using of combined random coding was proposed. At the same time, we recommend to use Blum-Blum-Shub random bit generator for the codebook creating. Blum-Blum-Shub random bit generator was chosen according to estimation results, obtained with the help of NIST Statistical Test Suite.
