МОДЕЛЬ КОНТРОЛЯ ЦЕЛОСТНОСТИ ДАННЫХ НА ОСНОВЕ ПРАВИЛ ПОСТРОЕНИЯ КОДА РИДА-СОЛОМОНА

The article deals with the Automated Systems (AS) operating under the destructive influences of an attacker and disturbances of the operating environment with a continuous increase in the amount of information accumulated in data storage systems (DSS) used in their interests. When compensating for the effects of an attacker and disturbances in the operating environment, the use of storage is complicated by the increased control information which entered for protection. At the same time, the amount of introduced redundancy is increasing in direct proportion to the increasing volume of information accumulated in the storage. For such operating conditions, one of the most important tasks is the organization of secure data storage with restrictions on allowable resource costs. A subsystem of data integrity control based on the cryptographic methods, in particular hash functions, is proposed. The hash function used in the developed subsystem is based on the rules of construction of the Reed-Solomon code, which makes it possible to detect and localize data arrays with signs of integrity violations without calculating and introducing a high redundancy of control information for this.

КОНТРОЛЬ ЦЕЛОСТНОСТИ ДАННЫХ НА ОСНОВЕ ПРАВИЛ ПОСТРОЕНИЯ КОДОВ С НЕРАВНОЙ ЗАЩИТОЙ СИМВОЛОВ

Information and analytical systems for various purposes are considered, the functioning of which is based on the processing of large multidimensional arrays of information in the conditions of destructive effects of an attacker and environmental disturbances. For such operating conditions, one of the most urgent tasks is the organization of secure data storage with a limited resource of the systems under consideration, ensuring the identity of the data from the operator who sent them for storage and from the decision-maker when requesting their use. A subsystem of data integrity control based on the use of redundant coding is proposed, in which the data to be protected is presented in the form of blocks, pre-grouped according to the criterion of “information value” to ensure the possibility of timeliness and correctness of a decision by the user of the system. The use of redundant coding in the developed subsystem is based on the rules for constructing codes with unequal character protection, which makes it possible to reduce the introduced redundancy of control information at given different levels of security of groups of data blocks processed in information and analytical systems.

Audit). The BMP system is used to perform maintenance and repair of equipment, as well as any other cases where personnel need to enter the danger zone, and includes not only the actual process of blocking and marking, but also all other activities: documentation, organization of storage and issuance of BMP devices, training and testing of personnel knowledge According to the analysis, the current tag system at the metallurgical enterprises of Ukraine is inferior in efficiency to the BMP system, which allows you to almost completely eliminate the risks associated with the human factor in the repair and maintenance of equipment. The foreign experience of using hazardous energy blocking and labeling systems and the existing legal framework on this issue in Ukraine are analyzed. According to the results of research, the basic principles of using the BMP system at the enterprises of the metallurgical industry are established. The sequence of BMP procedure implementation is offered. The information on the basis of which the BMP map is formed is considered in detail. An important stage in the formation of this map is the assessment of industrial risks of exposure to hazardous energies in the process of repair and maintenance of equipment. The direction of further research on the implementation of the BMP system and the legalization of the BMP standard at the state level is substantiated.

Audio-visual heritage preservation and the changing dynamics of Ghana’s historical film archives

ABSTRACT Current discourse on restitution and repatriation of Africa’s cultural heritage from Europe often eschews the large quantum of audio-visual materials kept in European archives. However, nation state sovereignty issues and concerns over easy access to film archives have attracted some level of scholarly attention, especially focussing on questions of ownership and its ramifications. From a historical perspective, this article draws attention to storage and preservation practices of Ghana’s audio-visual archives and suggests that current practices impede greatly on public access to film materials. Emphasis is placed on post- independent Ghanaian films, produced by the Ghana Film Industry Corporation and currently stored with a UK laboratory. rely on data from correspondence between the government of Ghana and storage organizations as well as interviews with key actors within the Ghana film industry to posit that in spite of debates in favour of digitization as the solution to access, the technology must be adopted cautiously where issues of ownership, copyright and the place of the tangible materials take centre stage beyond the digitization process for a sustainable access to Ghana’s archived audio-visual materials.

A novel cloud management framework for trust establishment and evaluation in a federated cloud environment

Cloud Computing is being utilized by large-scale organizations for data storage and management. It provides advantages like reducing the cost of information technology services by shared computing resources and more data storage space, in addition to on-demand and easy pay-per-use service mechanism. Different Cloud Service Providers (CSPs) form cloud federation to share their resources. In a cloud environment, it is essential to make sure that the customer’s data is fully secured, and standard privacy laws are applied to form a trusted relationship among CSPs and customers. Therefore, the focus of this research is to identify the issues for establishment of a trusted environment and evaluation of trusted levels between customers and their CSP. In this paper, a Federated Cloud Trust Management Framework (FCTMF) is proposed that resolves the trust issues and motivates the cloud providers to successfully participate in cloud federation. The proposed framework evaluates the level of trust based on Service Level Agreement (SLA) parameters, also considering customers and participating CSPs’ feedback. The results and comparison exhibit that the proposed framework is more accurate and feasible in terms of calculating level of trust.

Labor conditions at enterprises of Irkutsk region and implementation of the risk-based approach

One of the serious economic problems of modern production is losses caused by work-related injuries and occupational diseases, which amount to 4% of GDP. One of the ways to reduce significant economic losses is to change the paradigm from responding to an accident and occupational diseases to preventing negative factors of production processes. Russia is undergoing a large-scale reform of control and supervisory activities and transition to the risk-based approach is under way. According to the risk-based approach, attention of the regulatory authorities should be focused on potentially dangerous objects related to risks 1, 2. The purpose of this article is to analyze innovations in labor protection within the ʺregulatory guillotineʺ in assessing working conditions and managing occupational risks using the example of economic facilities in Irkutsk region and determining economic costs depending on the working conditions. The methods of statistical research, assessment of professional risks and economic costs were used. It was found that every second employee has performed his labor duties under harmful and (or) dangerous working conditions. The most difficult working conditions are typical of extraction, processing and agricultural enterprises, the intensity of labor is maximum during storage and transportation. When predicting professional risks for the main factors of the production process by economic activities, it was found that the maximum risk is observed in the construction, transportation and mining industries. The main reasons for high risks were identified. In Irkutsk region, the actual expenses for compensation and personal protective equipment amounted to 11,235 rubles per one person. Mining enterprises have the highest expenses (95,156.5 thousand rubles); the amount of expenses in the construction industry is 47440.6 thousand rubles; in transportation and storage organizations, it is 359,602.5 thousand rubles. The minimum costs are in companies engaged in agriculture, forestry, hunting, fishing and fish farming. Economic costs are significant and require measures to improve working conditions and ensure the effective modernization of the OSH management system. Currently, transition to the risk-based approach and creation of a system for managing industrial risks are the main tasks of managers at different levels.

Resource Utilization-Aware Collaborative Optimization of IaaS Cloud Service Composition for Data-Intensive Applications

Recently, growing cloud services (CSs) have been leased by organizations for high-performance computation and massive data storage of data-intensive applications (DiAs). To improve the resource utilization of leased CSs, it has become a challenging task to optimize infrastructure as a service CS composition for DiAs (ICSCDs) from the user side. This paper proposes a resource utilization-aware collaborative optimization approach. Targeting the collaboration features of tasks in a DiA, the environments-classes, agents, roles, groups, and objects model is used to formalize the ICSCD problem from the perspective of role-based collaboration. Aiming at the dynamic characteristics of the cloud environment, an integrated method is presented to evaluate the qualification of CSs via the interval numbers with multiple parameters. Based on the exact qualification values, the ICSCD can be optimized for improving the resource utilization of the CSs. A solution using the IBM ILOG CPLEX optimization package is put forward to solve the problem. The experimental results demonstrate that the approach can provide high precision, performance, stability, resource utilization, and low usage cost for the resource utilization-aware ICSCD from the user side.

It is concluded that digital technologies have led to a change in the culture of music consumption and, accordingly, have transformed the processes of storing music archival recordings in the repositories of radio companies, which have acquired specific properties. Examining music radio recordings as archival objects have shown that in the age of the digital revolution, the music industry around the world has undergone significant changes. Both the revenue structure and the cost structure of record labels and music radio companies have fundamentally changed. Conclusions. Digital technologies have led to a change in the culture of music consumption (there has been a change in the ideology of authorship for music products) and the emergence of digital recording technologies that use artificial intelligence, digital workstations, etc. In this regard, the specifics of the organization of storage of music archival recordings were transformed, in particular in the phono repositories of radio companies that have acquired specific properties of the service grade (reprint of archival music recordings that were previously specially recorded for radio stations).

ПОНЯТТЯ БЕЗПЕЧНОГО ЗБЕРІГАННЯ РАКЕТ І БОЄПРИПАСІВ

Events of recent years, namely explosions at arsenals in Balakleya, Kharkiv region, Kalinovka, Vinnytsia region, field depots near Svatove, Luhansk region, p. Maloyanisol, Donetsk region, village StarayaMykolayivka, Donetsk region, point to an imperfect system of ammunition storage organization, including an imperfect method of determining safe distances between ammunition storage places, which leads to significant material and human losses. Therefore, the survivability of missile and ammunition storage facilities requires, first of all, a review of issues related to the safe distances between missile and ammunition storage sites, and new ways of protecting ammunition storage sites. The main task of arsenals, bases and warehouses for missiles and ammunition of the Ministry of Defense of Ukraine is to ensure reliable storage and a high level of technical condition of stored missiles and ammunition, as well as their constant readiness to perform work at any time of day and under any circumstances. Theactivitiesofarsenals, bases and warehouses are always associated with increased risk, as these facilities are designed to store ammunition containing gunpowder and explosives. Closely related to the concept of security is the concept of survivability of arsenals, bases and ammunition depots – that is, their ability to perform their functions in a volume not lower than a given level for a certainperiodoftimeinemergencyconditions. The allowable risk depends on many factors, some of which are objective, such as the amount of explosive, its type, packaging of explosives and devices, their placement in storage or on sites (platforms, under canopies), distance, nature of the terrain and its contours etc. Other factors are more subjective – how receptive are the expected consequences of an explosive event or accident? For example, how many deaths, how many serious injuries, how many buildings were destroyed or damaged, how many destroyed munitions and other losses are allowed? Therefore, it is clearly important to know well the nature of the main danger, namely an explosion or fire, as well as the expected development of the accident: instantaneous, progressive, sudden, and so on. Standards have been developed for decades by explosives safety experts. Safe distances have been developed on the basis of analyzes and tests of a large number of explosives and data obtained from past emergencies. Potential explosion sites are sites such as buildings, stacks and vehicles (trucks, trailers and railway cars) that pose an obvious risk to personnel and property of arsenals, bases and warehouses. Such sites are located at carefully calculated distances from each other and from other buildings and institutions to ensure minimal risk to life and property (including ammunition). Keywords: arsenal, base, composition, gunpowder, explosive, security, ammunition.

Теоретические и практические аспекты реализации проекта «Единый архив электронных документов» Казахстана

Under present-day conditions of digital transformation of the economy, the problem of storing and using electronic documents is quite relevant. As a result of consistently pursued state policy of informatization of Kazakhstan, in recent years the share of electronic documents accumulated in various national information systems has significantly increased. The article is devoted to the project “Unified Archive of Electronic Documents” (UAED) implemented within the frameworks of the State Program “Digital Kazakhstan” adopted in all departmental and state archives of the republic. It represents a practical solution for organizing long-term and permanent storage, order, and usage of electronic documents. The author describes main components and functionality of the system for automating the activities of both departmental and state archives, maintaining the State Fonds Catalog, providing remote access to archive’s data through web portals "E-Archive" and "Electronic Government," generating statistical reports on various indicators for various time periods, composition and content of archival fonds, state of storage of documents, etc. The article describes procedure and form for accepting electronic documents for storage in the UAED, where the main condition is to confirm the validity of electronic digital signature. It also underscores the problem of verification of documents that did not pass this check. The regulatory legal framework for implementation and functioning of the system has been investigated. The article notes existing loop-holes in the legislation on the issues of ensuring legitimacy and authenticity of electronic documents when transferring for storage, of electronic digital signature integrity, and of electronic files formation. In particular, it underscores the necessity of legislative consolidation of the “time stamp” concept and the mechanism of its use when verifying electronic documents. The problem of choosing a format for long-term data storage is outlined. An example of using such electronic documents property as possibility of their machine processing for automation of the process of forming files and compiling series is considered. It is noted that nation-wide introduction of the UAED has made it possible to unify and systematize the process of transferring archival documents into digital format. The author concludes that, in order to solve practical problems of archival storage of electronic documents, it is necessary to conduct scientific research and acquire theoretical understanding of a number of issues (selection, examination of value, organization of storage, use of electronic documents, etc.).
