Deploying and Assessing the Efficiency of Ethereum Blockchain for Ensuring the Security of Web of Things

Gagandeep Singh Cheema, Babli Dhiman, Manik Rakhra, Rajinder Singh Kaundal · 6 authors

The characteristics of blockchain technology, which is a decentralised database or "distributed ledger," include independence, lack of central authority, and a trustless setting. Because of these characteristics, blockchain technology is well-suited for use in many IoT applications. This article details a real-world use of the Proof of Authority (PoA) Ethereum blockchain on an web of Things (IoT) system. In order to study and highlight potential challenges that might impact the integration of blockchain with IoT, and to set the stage for future research and potential solutions to these concerns, this implementation was carried out in a practical sense.

ЗАХИЩЕНЕ ЗБЕРІГАННЯ ДАНИХ ІЗ ВИКОРИСТАННЯМ ТЕХНОЛОГІЇ БЛОКЧЕЙН ETHEREUM

Олег Гарасимчук, Юрій Наконечний, Тарас Луковський, Роман Андріїв · 5 authors

Постійне збільшення обсягів даних породжує проблеми, пов'язані з вибором ефективних методів та засобів зберігання, а також забезпеченням захисту цих даних від несанкціонованого доступу. У статті детально розглянуто критичну тему збереження та захисту важливої інформації в умовах зростання обсягів даних і численності кібератак. Необхідність надійного збереження і захисту даних наростає, особливо у контексті підвищеної загрози з боку зловмисників. Висвітлюється, як блокчейн-технології, особливо на базі платформи Ethereum, можуть вирішити проблеми надійного збереження і безпеки даних. Ethereum пропонує альтернативу традиційній клієнт-серверній моделі, децентралізуючи зберігання даних за допомогою розподіленої мережі вузлів. Ця технологія значно підвищує безпеку, ускладнюючи несанкціонований доступ до інформації, оскільки для злому приватного ключа потрібні значні обчислювальні ресурси. Смарт-контракти на Ethereum дозволяють створювати застосунки, які виконуються точно відповідно до заздалегідь визначених умов, без можливості втручання третіх осіб. Це особливо важливо для месенджерів, де конфіденційність і доступність даних мають принципове значення. Вартість транзакцій в блокчейні, хоча й висока, компенсується високою надійністю та безпекою зберігання даних. Застосована методологія підтверджує, що використання публічного (децентралізованого) сховища даних є безпечним, оскільки зламати приватний ключ Ethereum практично неможливо.

Methods of increasing data reliability based on distributed and parallel technologies based on blockchain

Nazarov Fayzullo Makhmadiyarovich, Yarmatov Sherzodjon

This article examines directions and mechanisms for increasing data reliability in computer networks. Currently, the rapid development of information technologies, the rapid growth of data flow, high-quality data processing carried out in network technologies, and the increase in the volume of data lead to an increase in the problem of data reliability. It is an urgent issue to find solutions based on the use of modern technologies to solve these problems. The simultaneous processing of various types of data in information systems, video, audio, text and digital data, creates big data. The variety of data types in bigdata creates the problem of quality data processing, which greatly affects the reliability of the data. Research shows that breaches of data integrity mainly manifest in three directions. In this case, there is a violation of the reliability of interrelated data in data transmission and storage, in the processing of large volumes of data and in the transcription of video data. It is created due to errors created during data transmission based on artificial and natural redundancy. To solve the mentioned problems , increasing data reliability based on blockchain mechanisms for payment systems in data transmission, increasing data reliability based on error minimization mechanisms in video information systems, and distributed computing and parallel mechanisms in large-scale information systems based on methods of increasing data reliability are researched.

MULTI-AGENT MODEL OF GROUP CONTROL POINT OF UNMANNED AIRCRAFT AND UNMANNED GROUND VEHICLE WHEN PERFORMING SPECIAL MISSIONS

Ihor Hurin, L. Matvieiev

Unmanned aerial vehicles (UAVs) are becoming very important platforms for conducting combat operations in the russian-ukrainian war, as they significantly reduce the risk of human life during special and combat missions. The UAV group can be used to perform a wide range of military tasks: destruction of enemy equipment, reconnaissance (monitoring) of the area, construction of aerial networks, etc.
 In the conditions of a change in the tactical situation, countermeasures by the enemy, effective management of the UAV group is impossible without an appropriate management system. The UAV group can include both unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UAVs). The following main tasks are assigned to the management system: determination and coordination of the order of joint actions of autonomous UAV groups; formation of flight (ground) tasks and flight (movement) trajectories of the UAV group; dynamic adjustment of the flight task and the role of each UAV during its use; organization of the communication network between the control center and between UAV groups, etc. The tasks and target functions of management of each of their subsystems are determined. The features of the UAV group control cycle are described.
 The main stages of the synthesis of the control system are considered: the choice of the control method (centralized, hierarchical, decentralized and mixed); selection of algorithms (protocols) and organization of the process of data exchange between UAVs. A functional model of the UAV group management system is proposed. Tasks and main management functions of each of the subsystems are defined. Features of the UAV group management cycle are described. The main stages of the synthesis of the control system are considered: the selection of algorithms (protocols) and the organized process of information exchange between UAVs; variants of formation and swarm models of UAV movement in groups; multi-agent decision-making models for the organization of task performance by the UAV group.

Development of recurrent neural networks for price forecasting at cryptocurrency exchanges

Victoria Tyshchenko, Світлана Ачкасова, Олексій Найденко, Serhii Kanyhin · 5 authors

The study focuses on improving the quality of using recurrent neural networks (RNNs) to predict cryptocurrency prices. The formula of the target variable for the model based on the arithmetic mean is developed, which allows us to better take into account the dynamics of cryptocurrency exchanges. The factors affecting this variable were grouped into features based on the volume of daily cryptocurrency trading, the volatility of the relevant prices, and the pre-calculated and selected signals of technical indicators. As part of the study, an algorithm for processing daily data was developed for the model. The results obtained made it possible to create a holistic model for forecasting stock prices. Two recurrent neural networks were trained: one with a long short-term memory (LSTM) and the other with a recurrent gate unit (GRU). To determine the efficiency of the models, the analysis was carried out using two key indicators: the Sortino coefficient, which measures the relative risk/reward for each additional unit of unwanted volatility, and the Sharpe ratio, which measures the return on assets, subtracting the free risk. As a result, it was found that both models have similar results in terms of accuracy (~69 %). Still, the GRU-based model showed significantly better values of the Sortino coefficients (3.13) and Sharpe’s coefficient (2.45), which allows us to conclude that it is effective on cryptocurrency exchanges. At the same time, the LSTM model requires more parameters for training than the GRU model with an identical structure, which leads to a longer training time. The obtained scientific and practical results are aimed at more efficient use of recurrent neural networks in price forecasting on cryptocurrency exchanges

Blockchain Technology for Authentication and Validation Social Network Accounts

Zacky Althero, Jazlan Syahreza, Alvano Ortiz

By distributing personal information and profile pages in blocks and verifying them using blockchain technology, SNS becomes a point of trust. This study proposes a practical and straightforward technical method to authenticate profiles on social networks. Anyone can use this mechanism to authenticate a social media account, increasing the chances of identifying the natural person behind the account. Furthermore, fake accounts are exposed this way, creating a more secure and trustworthy social media environment. Blockchain technology is a participatory mechanism between private information and the blockchain, and only developers are required to modify the properties of the platform directly. The actual personal information of the account holder is stored in encrypted blocks that are difficult to modify, copy or steal and are displayed on the profile page.

On the Technologies of Decentralized Social Networks

Semyon Anikeev

The article analyzes modern centralized social networks, taking into account the existing shortcomings. A methodical approach to the development of a multiplatform decentralized social network using an interplanetary file system is proposed. Besides, a decentralized social network, an Ethereum smart contract, and a module for interacting with the interplanetary file system have been developed, a solution for the client side had been designed, a database and a local server have been configured. The ways to increase the speed of loading content are analyzed. To develop the client part of a decentralized social network, several popular frameworks have been proposed. Adapted life cycle models have been investigated, that is, ways to describe the stages of software development, depending on the characteristics of a particular project. Given the specifics of developing a multi-platform decentralized social network using IPFS, Agile is supposed to be the most appropriate life cycle model. An algorithm is proposed to calculate the computational and capacitive complexity of the system being developed. The calculation takes into account the main functions of the system components.

Intelligent SDN Architecture With Fuzzy Neural Network and Blockchain for Monitoring Critical Events

Alexey Finogeev, Michael Deev, Данила Парыгин, Антон Финогеев

The article deals with the creation of an intelligent architecture of the Internet of Things transport environment based on software-defined network (SDN) and blockchain for detecting threats and attacks. The transport environment is created for the monitoring system of critical events in the road transport infrastructure. Blockchain technology is used to authenticate network nodes, store sensor data in a distributed ledger. The network packet clustering method based on a fuzzy neural network is used to detect packets with possible malicious content. The intelligent SDN architecture is a hierarchy of four layers with six levels and includes: a) edge computing layer (sensor nodes and routers level, SDN switches data level), b) fog computing layer (zone server level, control level in SDN controllers), c) a cloud computing layer with data center servers, d) a layer for presenting monitoring results on user devices and applications. Detection of threats and attacks is implemented by validating network nodes and analyzing header fields of IP packets and TCP segments. The intrusion detection system includes a parser and analyzer of data packets, a module for filtering traffic by type, port numbers and other characteristics of packets, a module for synthesizing digital signatures of trusted nodes and their validation, a module for analyzing and clustering packets based on fuzzy logic and a neural network, modules for logging procedures. The probability function of packets belonging to clusters is tuned through deep learning of a five-layer neural network. The conclusion about belonging and degree of similarity with malicious packages is formed using the fuzzy logic apparatus. To train the neural network, the previously synthesized rules of the flow tables and the identified signs of atypical data packets are used. The functionality and effectiveness of the SDN architecture with an intrusion detection system is validated by simulating procedures in the NS3 Simulator system, evaluating authenticity, latency, throughput, response time, and accuracy in detecting atypical data packets.

A novel architecture of a secure medical data storage management system based on tangle

Oleksandr Shmatko, Yaroslav Kliuchka

Electronic health information exchange allows providers to healthcare providers and patients to securely access vital medical information of the patient and share it in electronically with other healthcare providers. However, existing health systems for the exchange of medical data faced with a number of problems, in particular: security, confidentiality and fragmentation of medical data. Data information systems are isolated because each medical institution, laboratory, doctor use their own system. The patient cannot access their medical information in the right time, since patients still do not have access to these systems. And the exchange of medical information between doctors occurs through mail or patients carry their own medical records with them admission to reception. In healthcare, there is no single system that allows both doctors and patients to have permanent access to the history the patient's illness and prescribed treatment. The paper considers the electronic health system eHealth. In this system, all medical data is stored on central component, and physicians using information systems gets access to them. However, this system has its limitations: single point of failure, lack of a unified medical information systems and patients still do not have access to their medical data. Therefore, one of the solutions to these problems is to create systems for exchanging medical information using directed acyclic graph (DAG). DAG will allow freely exchange data with a guarantee of their integrity. The patient's medical records will be stored in a distributed ledger, and not on the server of the medical institution. So no one can change patient data or deny him access to his own data. The use of DAG is considered on the example of the transfer of medical patient data to the doctor. The process of creating and sending medical data to DAG is illustrated with a specific example.

ВІДМІННІСТЬ МІЖ DLT (DISTRIBUTED LEDGER TECHNOLOGY) ТА БЛОКЧЕЙНОМ, ЯК СПОСОБАМИ ЗБЕРІГАННЯ ІНФОРМАЦІЇ ПРО ЕКОНОМІЧНІ ТРАНЗАКЦІЇ

В.В. Сержанов, Я.Л. Кочан

Метою статті є аналіз тлумачення словосполучення Distributed Ledger Technology (далі DLT) таблокчейн, визначення спільного, та відмінного, переваги та недоліки технологій. З'ясовано, що блокчейн єпідмножиною DLT, і використовувати термін блокчейн не завжди доречно та тлумачно правильно,краще використовувати термін DLT. В патентах та статтях було виявлено, що термін DLT все жтаки був використаний раніше ніж термін блокчейн, хоча багато авторів статей, чомусь помилкововважають, що саме блокчейн породив поняття DLT.Окремо у статті розкрито, позитивні та негативні аспекти блокчейну, а також проведенакатегоризація DLT. Звернуто увагу на те, що вузли, які проводять та контролюють операції вдецентралізованих мережах, залежно від типу систем можуть по різному називатись, від валідаторівдо нод.Визначено, що DLT є більш грамотним та тлумачно вірним терміном ніж блокчейн, і використовуючийого, автор ніколи не помилиться в суті
