THE CONCEPT OF INFORMATION SECURITY IN THE IOT SYSTEM
Abstract
The subject of the study are the processes of securing information in wireless control and communication channels of the Internet of Things (IoT) system. The goal is to develop the concept of broadband Internet access and the implementation of key security competencies in the implementation of IoT projects. The task is to ensure stable and secure operation of the IoT system. The model is based on the reference model DigComp 2.0, created within the framework of a system of digital competence of citizens. Moreover, the main area of competence of this model is security. The method used: methods of analytical, simulation modeling and temporal position-pulse coding. The following results are obtained: A security concept has been developed in the wireless control and communication channels of the IoT system. It is shown, that to obtain high noise immunity of control and communication channels and to protect information from interception, wireless ultra-wideband communication technology should be used, which allows for large volumes and speeds of information transfer. The possibility of joint interference-free operation in the same frequency range of both traditional narrow-band communication systems and systems using ultra-wideband signals is substantiated. A technical solution for the design of an ultra-wideband receiving - transmitting antenna system is proposed. Conclusions. The use of channels with an ultra-wide frequency band allows for an increase in the number of control and communication channels of the IoT system. Pre-distribution between the channels of orthogonal codes implements the process of control and communication without interception of information and mutual interference. Moreover, the application of the method of temporal position-pulse coding prevents inter symbol distortions of ultrashort pulses coding. It also reduces the level of distortion of information signals caused by its multipath propagation, which guarantees the security of information in the IoT system.
