METHODOLOGY OF THE ORGANIZATION OF THE HIDDEN DATA EXCHANGE IN THE NOTIFICATION SYSTEM OF THE NGU BASED ON THE USE OF GSM-COMMUNICATION

Abstract

The effective functioning of any military unit, including the National Guard of Ukraine, is impossible without an effective system of government. In turn, the operation of the control system is ensured by the communication and control automation systems. As a rule, special means of communication and data transmission are used in combat conditions, but in daily activities, in particular in the alert system, publicly available channels and data communication facilities are more commonly used, such as wired city telephony and GSM mobile networks. An analysis of modern digital cellular communication technologies and determining the feasibility of using it in the construction of a radiocommunication system and alerting the National Guard of Ukraine showed that public channels of communication can be used in peaceful times and in preparation for their intended purpose due to their widespread distribution. The use of the proposed methodology for organizing the communication system in the NSU alert system ensures the secrecy of transmitting alert signals to personnel, subject to the use of GSM communication. It is advisable to use open source software, which is distributed free of charge, for the organization of secure communication channels in the NSU grouping system under limited funding conditions. Such software enables efficient cryptographic protection of files and messages transmitted through the communication system. It is proposed to use VPN virtual private network technology as a software for organizing a secure data exchange system. For its implementation it is suggested to use free open source programs: the program of creating channels for the client-server OpenVPN; TeamSpeak Voice Dialer; program for encrypting messages, files and other information for electronic exchange between VPN subscribers. To provide the necessary degree of secrecy of the alert system, it is proposed to use data and message encryption systems with PGP public keys.
