    The article presents a new way to increase the cryptographic strength of MAC codes for messages transmitted over the Internet. Today, this should make it possible to resist both the consequences of cyber threat aggregation and increase the speed of unauthorized access to data through the creation of such new hardware capabilities as quantum computer technology. The paper proposes to consider the application of the modified UMAC algorithm on modified McEliece elliptic curves using crypto-code structures with hybridity features. The proposed structures were tested for collision properties. For this, a software application was developed in the environment of the object-oriented programming language C#. To determine the capabilities of the studied hash-codes, a complex indicator of the effectiveness of the modified UMAC algorithm was developed. This made it possible to test the proposed designs for resistance to hacking, consider the value of the data that is being protected, and the safe time for a possible hack. As a way to assess this indicator, it was proposed to use the method of multivariate complex analysis. For this, scales for measuring and interpreting each indicator were developed. It has been proven that this method of evaluation allows one to obtain adequate results and combine them with the results of accurate calculations for individual parameters. The issue of reducing energy costs for the formation of crypto-code structures was also investigated. The results showed that the creation of hybrid crypto-code structures leads to the lowest energy costs.У статті представлено новий спосіб підвищення крипостійкості МAC-кодів повідомлень, що передаються через Інтерне-мережі. На сьогодні це має дозволити протистояти не тільки наслідкам комплексування кіберзагроз а й підвищенню швидкості несанкціонованого доступу до даних через створення таких нових апаратних можливостей, як квантова комп'ютерна технік. В роботі пропонується розгляд застосування модифікованого алгоритму UMAC на модифікованих еліптичних кривих Мак-Еліса із використанням крипто-кодових конструкцій з ознаками гібридності. Проведено перевірку запропонованих конструкцій на колізійні властивості. Для цього було розроблено програмний додаток в середовищі об'єктно-орієнтованої мови програмування C#. Для виявлення можливостей геш-кодів, що досліджувалися, з точки зору їх стійкості до злому, цінності даних, у захисті яких вони повинні застосовуватися та з врахуванням безпечного часу до можливого злому, було розроблено комплексний показник ефективності модифікованого алгоритму UMAC. У якості метода оцінки даного показника було запропоновано використовувати метод багатофакторного комплексного аналізу. Для цього були розроблені шкали вимірювання та інтерпретації кожного показника. Доведено, що даний метод оцінки дозволяє отримати достатньо адекватні результати та поєднати їх з результатами точних розрахунків за окремими параметрами. Також було досліджено питання зниження енергетичних витрат для формування крипто-кодових конструкцій, за результатами якого було доведено, що створення саме гібридних крипто-кодових конструкцій призводить до найменших енергетичних витрат

    The Brazil, Russia, India, China, South Africa (BRICS) nations lack a cohesive cybersecurity framework for intelligence exchange. The proposed expansion of the BRICS bloc calls for a BRICS+ agency dedicated to cybersecurity information sharing and analysis. Information Sharing and Analysis Centres (ISACs) are successful not-for-profit entities that centralise resources for gathering, analysing, and disseminating cybersecurity intelligence. However, founding a BRICS+ ISAC confronts challenges such as coordination complexity, financial constraints, trust deficits, linguistic diversity, and disparate legislative landscapes. This paper proposes a novel hybrid ISAC architectural model that amalgamates centralised and decentralised elements, presenting a tailored solution for the multifaceted needs of the expanding BRICS+ entity. The innovation of this model lies in its capacity to enhance cybersecurity resilience, promote efficient intelligence exchange, elevate the BRICS+ international standing, and solidify inter-nation collaboration, while being flexible enough to cater to the specific legal, cultural, and technological variances across member countries. The proposed model's uniqueness and adaptability position it as the premier choice for actualising the BRICS+ vision for a unified cyber front
