Today the current problem is the control of parameters of power equipment within the automation systems of oil refineries, such as the current one. This problem is quite relevant, since the operation of power equipment at oil refineries implies a form of network currents significantly different from sinusoidal thus impacting the quality of the network parameters, and this, in turn, has significant effect on the results of current measurements in power circuits of process equipment within the automation systems. This work is devoted to modeling and study of the proposed magnetodielectric measuring transducer of alternating current (MDT) based on modern materials. The purpose of the study covers theoretical analysis and mathematical modeling of alternating current measuring transducers based on magnetodielectric cores for automation systems in oil refineries.

Development and Mathematical Modeling of the AC Sensor for Refinery Automation Systems

The main aim of the research is the development of effective methods and algorithms based on the hybrid principles functioning of the immune system and evolutionary search to determine a global optimal solution to optimisation problems. Artificial immune algorithms are characterised as diverse ones, extremely reliable and implicitly parallel. The integration of modified evolutionary algorithms and immune algorithms is proposed to be used for the solution of above problem. There is no exact method for the efficient solving unclear optimisation problems within the polynomial time. However, by determining close to optimal solutions within the reasonable time, the hybrid immune algorithm (HIA) is capable to offer multiple solutions, which provide compromise between several goals. Quite few researches have been focused on the optimisation of more than one goal and even fewer used to have distinctly considered diversity of solutions that plays fundamental role in good performance of any evolutionary calculation method.

The algorithm development based on the immune search for solving unclear problems to detect the optical flow with minimal cost

Within the framework of this paper, a methodology for non-destructive acoustic spectral-timbre computer technological control of composite materials is proposed, which provides tracking and registration of the diagnosed quality parameters and detection of defects according to standard parameters. The completeness of the diagnosis, high accuracy and self-testing of the measuring system is achieved by using mathematical software with the preservation of all hardware modules.

The aim of the study is to improve the quality and level of security of an information system for monitoring cargo vehicles at production sites via modern encryption methods, which will provide for accurate management decisions in the event of a system breach. In accordance with modern requirements of information security policies, enhancement of information system security assumes the development of data protection concepts and the implementation of the most advanced encryption methods within the information system. The paper presents the authors’ solution for constructing an information system using SSL-based data encryption, SSL standing for the Secure Socket Layer. The characteristic feature of SSL-based encryption is the creation of a public-key cipher. This enables user and server authentication via digital signature technology. In addition, the method produces a session key that can be used to develop a fast symmetric cipher algorithm that allows encrypting of large arrays of information. Based on the proposed concept, the authors develop an information system for monitoring cargo vehicles at production sites that employs SSL-based encryption.

Building Algorithms Based on Artificial Intelligence for Solving Problems to Ensure Information Security

The topic of pseudonymization of personal data has shown, that theoretical and methodological basics in sphere of automatized systems have just started to gain general trend. The majority of studies in this sphere are, commonly, about personal data in general, rarely touching the topic of pseudonymization and depersonalization. Therefore, the topic of pseudonymization has not fully assimilated in enterprise systems and has not grown any popularity, because enterprises tend to choose reliable tools and methods of information security while depersonalization is only beginning its way and is not common for big corporations. This leads to disinterestedness in solving known issues and goals of pseudonymization, universal methods have not been researched. However, low cost and simplicity of this method of personal data protection is turning our attention on it and ask ourselves a question: “Should we have a deep dive in it?”. Answer is obvious – yes. Certainly, this method has its disadvantages and it is not an ideal solution. But it certainly should be distributed worldwide.

Theoretical aspects of the protection of personal data of employees of the enterprise by the method of pseudonymization

Objective. The article discusses hardware and software methods of protecting the resources of the personal data information system from unauthorized access by means of "sniffing attacks"; the essence of which is to intercept data that is delivered within the observed system in the form of packets.Method. The analysis of the security of resources by the personal data information system regarding unauthorized access to data by means of "sniffing attacks" includes five conditional stages: collecting information in the personal data information system, scanning the personal data information system, gaining access to the personal data information system, securing personal data in the information system, generating a report; at the same time, security analysis it is always associated with unauthorized access to data.Result. To prevent unauthorized access to data by means of "sniffing attacks", the following software and hardware solutions are proposed to minimize the consequences of unauthorized exposure to the personal data information system: the use of the HTTPS protocol, a secure version of the HTTP protocol; the use of a static ARP table generated manually; scanning of the computer network of the personal data information system by the AntiSniff program; encryption of the computer network traffic networks of the personal data information system.Conclusion.The presented hardware and software solutions allow minimizing the consequences of unauthorized impact on personal data information systems.

Objective. A high-quality "cloud storage" of data should ensure the confidentiality, integrity and availability of information in the "storage". The use of "cloud storage" for storing information in backups is associated with their possible loss. Ensuring the confidentiality of information in the "cloud storage" implies that by "uploading" data to the "cloud storage", the user must be sure that an attacker will not be able to obtain information from the storage. The aim of the study is to develop an algorithm for using a cross-platform mobile application to protect information in the "cloud storage" of IS.Method. The study is based on the use of a cross-platform approach to creating applications.Result. The analysis of existing approaches and frameworks for the development of crossplatform mobile applications was carried out. It is proposed to create an application based on the Xamarin framework. To ensure the confidentiality of information, it is proposed to encrypt them before uploading data and backup copies of files. Encryption involves hiding the original type of the file from unauthorized use using crypto-algorithms, when the owner of the encryption key is the authorized user. To implement the function of encrypting data and backup copies of files uploaded to the "cloud storage", it is proposed to use the Rijndael symmetric block encryption algorithm, adopted as an encryption standard according to the results of the Advanced Encryption Standard (USA) competition.Conclusion. A cross-platform mobile application can be compiled and run efficiently under iOS and Android operating systems, encrypt files and upload them to the "cloud storage" with the possibility of subsequent decryption.
