  • Blockchain technologies and their application in security software development
    Serhii Zybin, Oleg Kubrak, Petar Halachev, Yaroslav Kravchuk, Oleksandr Muliarevych
    Sustainable Engineering and Innovation, 2025
    Current factors like the rising frequency of cyber threats and vulnerabilities on centralized platforms indicate the inefficiency of conventional network security frameworks, leading to new solutions such as the blockchain. This review systematically reviews developments of blockchain technologies in the context of security software (2021-2023) to evaluate its efficacy and challenges and explore the future potential. 77 peer-reviewed papers from ScienceDirect, IEEE Xplore and Scopus; adopting the PRISMA guideline, records were screened down from 1,532 to 77. Empirical evaluations (35%), case studies (28%), and theoretical frameworks (37%) using Joanna Briggs Institute tools and the Newcastle-Ottawa Scale were used in mitigating bias. Our results show that blockchain has strengths that add to data integrity (89% of studies) and security of the Internet of Things (IoT) ecosystem (28 studies) and supply chains (15 studies). Nevertheless, blockchain-based authentication has reduced latency by 284% (342 ± 112 ms) compared to a traditional system and has tradeoffs with scalability and performance. Research is skewed towards finance (47%), missing healthcare (9%), and critical infrastructure (6%). It does not include sufficient interoperability standards, post-quantum cryptographic validation, etc. The adaptive regulations are urged for policy implications for editable blockchains and hybrid Artificial Intelligence (AI) blockchain architectures. Interoperability should be taken care of by cross-chain protocols, scalability trilemmas and real-world adversarial testing must be addressed by the researchers and practitioners must put priority on scalability. This review, in its totality, brings out the singular role of blockchain in complementing the existing security solutions instead of replacing them. It calls for cross-disciplinary involvement and partnership in harnessing technical innovation in a regulatory framework to tackle cybersecurity threats through outsider and insider security approaches.

    Oleksandr Muliarevych
    Conference Proceedings 2024 IEEE 17th International Conference on Advanced Trends in Radioelectronics Telecommunications and Computer Engineering Tcset 2024, 2024
    This article examines cybersecurity vulnerabilities in systems utilizing Language Model Interfaces, focusing on the challenges of building secure systems. It provides an overview of current interfaces and their associated risks. A key contribution is the design of a prompt analysis and injection detection subsystem, which assesses input relevance and security. The integration of an additional Filter level in the system safeguards against prompt injection attacks by pre-processing user requests and post-processing responses. This level includes a Prompt Analyzer for input wrapping, and an Attack Validator module using the LLM to classify prompts. The study evaluates various prompt injection attacks across different system setups, including core GPT -3 and GPT-4 models without additional security layers, a Fuzzy Search method, and systems using an Attack Validator based on GPT-3 and GPT -4 models.

    Journal of Curriculum and Teaching, 2023
    The article aims to analyse digital education in terms of modern information and the digital learning environment. Based on the use of such theoretical pedagogical research methods as system analysis, concretisation comparativistic approach the study is investigated. The results demonstrate the functioning of educational hubs as a sociocultural phenomenon in modern educational policy, the modern experience of using digital hubs in education, particularly, the experience of CISCO and other influential players, the possibility of forming digital learning hubs based on libraries of higher education institutions. It is shown that important directions for further research are the coverage of the development of technologies and the impact of this process on the evolution of educational environments in the future. In conclusion, it was noted that the use of educational digital hubs contributes to the decentralisation of the educational system. The effectiveness of the use of regular test competitions are noted, which contributes to the formation of a competitive environment.
