Item Аналого-дискретний пристрій, захищений від витоку побічних електромагнітних випромінювань. ANALOG-DISCRETE DEVICE PROTECTED FROM CONTINUOUS ELECTROMAGNETIC RADIATION(2018) Дудикевич, В.Б.; Dudykevych, V.B.; Опірський, І.Р.; Opirskyi, I.R.; Гаранюк, П.І.; Haraniuk, P.I.; Березюк, Б.М.; Bereziuk, B.M.; Ракобовчук, Л.М.; Rakobovchuk, L.M.The design of an analog-discrete device is developed. Its feature is the absence of external voltage sources, converters and voltage dividers, and thus protected from leakage of side electromagnetic radiation. Since the electro-optical effects in liquid crystals have a threshold character, this property will lie at the basis of the use of liquid crystals to create indicators with a low level of radiation. These indicators are distinguished by a low power consumption, high reliability, simple design and low cost. The transformation of an electrical signal into an optical counting occurs in a liquid crystal display. This is achieved due to the fact that the reference electro- optical elements are connected with a voltage divider, whose role is performed by a high-level electrode, which is contained inside the indicator. The electro-optical reference elements are formed by mutually penetrating combing electrodes placed on the same glass substrate of the indicator. This greatly simplifies the technology of manufacturing the device, because the thickness of the layer of liquid crystal becomes insignificant and there is no need to strictly withstand it. The measured voltage is applied to contact pads, which are located at the ends of high-level electrode, which acts as a voltage divider. From the divider, the voltage is fed to one part (upper) of the comb electrodes, and to the second part (lower) of the electrodes, mutually penetrating with the help of a low-anode electrode. The topology of electrodes, including comb, is performed by milling fine films with an argon laser. In the study, we found out the criterion of the possibility of constructing a reference device with different degrees of reference, which uses the electro-optical effect in a liquid crystal with threshold voltage. And it has been shown that if such equality is not fulfilled, it is necessary to change the levels of voltage reference. The results of studies and calculations of the device on the twist effect and the effect of dynamic light scattering are presented. The results of experimental studies are quite consistent with the calculations, which testifies to the possibility of practical application of an analog-discrete display unit.Item Критична інфраструктура в аспекті євроінтеграційного курсу України у сфері забезпечення кібербезпеки. CRITICAL INFRASTRUCTURE IN THE ASPECTS OF THE UKRAINIAN EUROSTATION CURRENCY COURSE IN THE FIELD OF PROVISION OF CYBER SECURITY(2018) Дудикевич, В.Б.; Dudykevych, V.B.; Гаранюк, П.І.; Haraniuk, P.I.; Березюк, Б.М.; Bereziuk, B.M.; Ракобовчук, Л.М.; Rakobovchuk, L.M.; Дзяний, Н.Р.; Dzianyi, N.R.Paper presents the current state of cyber security in Ukraine, the USA and EU countries. On the basis of a comparative analysis, it has been established that to date, cybersecurity in Ukraine as an industry is at the initial level of development. The signing of the Association Agreement, its further ratification by Ukraine and a number of EU member states, stipulate the need to identify the first steps that Ukraine should take in order to bring its approaches in this area in line with the approaches applied in the EU in the area of critical infrastructure protection. Identified documents that need to be given special attention in the development of the national regulatory framework in the field of critical infrastructure protection. The specified documents are intended to bring the requirements of national legislation to the maximum as far as possible to the requirements for the functioning and protection of critical infrastructure in the field of energy and transport, as defined in the EU directives and specified in the Association Agreement between Ukraine and the EU. The measures of raising the level of critical infrastructure in the aspect of the European integration course of Ukraine are analyzed. In particular, taking into account the European integration course of our state, it has been established that in developing a system of critical infrastructure protection in Ukraine, efforts should be made to achieve consistency of the national legislation with EU normative acts regarding: general principles of the protection of critical infrastructure; interpretation of the main terms; consistency in the priority of protecting critical infrastructure; methodology for comparison and identification of priority objects in different sectors; implementation of the critical infrastructure protection standards in force in the EU. The main recommendations for raising the level of cyber security of critical infrastructure in Ukraine are substantiated, among them: comprehensive improvement of regulatory legal regulation of protection of critical infrastructure and development of international cooperation in the field of critical infrastructure protection. Therefore, the protection of critical infrastructure in Ukraine should be an integral part of the pan-European security mechanism.
