    • Security Aspects of the Regulation of Financial Market Infrastructure and Financial Services Distribution in the Internal Market of the European Union: The Perspective of the Czech Republic

      pg(s) 3-7

      The financial market and financial services are important sector of the economy where various types of risks arise. These risks affect both entities making their financial business as well as their customers. Some of these risks, especially those that are systemic in nature and that concern more vulnerable customers (typically consumers), are responded to by regulation as a key instrument of public intervention in the freedom of enterprise. Most of the current legislative framework in this area today has its prototype in the European Union member states in community law. The security aspects of the organization of the financial market and the activities of financial service providers are today the subject of a whole series of directives and regulations. Security here has either a primarily macroeconomic (ensuring financial stability) or a microeconomic dimension (protection of individual customers). The interest of the state in this area, which captures criminal activity here (money laundering, financing of terrorism, tax evasion), is specific. The aim of the article is to structure the system of these regulations, to analyse its (local) effectiveness using data from relevant administrative authorities of the Czech Republic and to estimate future developments in the area, taking into account current geopolitical dynamics within the European Union and globally.

    • A competency model for training specialists in biological security in the context of bioconvergence

      pg(s) 13-16

      The rapid advancement of biotechnology, artificial intelligence, big data analytics, and digital technologies is transforming the nature of biological risks and creating new challenges for security systems. At the same time, the processes of bioconvergence are fostering increasingly close interactions among the life sciences, engineering, information technologies, and security studies. This paper explores the implications of these developments for the education and training of biological security specialists. Drawing on a systems approach, comparative analysis, and conceptual modelling, the analysis identifies the key competencies required for effective professional performance in a dynamic technological environment. An original competency model is proposed, integrating fundamental biological knowledge, technological competencies, security-related expertise, and practical skills for biological risk management. The model provides a conceptual framework for the modernization of educational programmes and for strengthening sustainable capacity to address biological threats.

    • Zkap anti-corruption output filter: a cryptographically verifiable compliance protocol for the deployment of artificial intelligence in investigative, regulatory, supervisory and judicial procedures

      pg(s) 20-25

      The integration of artificial intelligence into judicial and administrative procedures raises a structural regulatory crisis. The European Union has imposed simultaneous and competing obligations: on one hand, the AI Act (Regulation (EU) 2024/1689) mandates transparency, human oversight, and accuracy for high-risk systems; on the other, the GDPR (Regulation (EU) 2016/679) and the Trade Secrets Directive (2016/943) impose strict confidentiality. This article proposes the ZKAP (Zero-Knowledge Audit Protocol) Anti-Corruption Output Filter as a cryptographically verifiable compliance mechanism that resolves the conflict at the operational layer of AI-assisted judicial workflows. The filter operates on a universal dual-axis decomposition of any procedural norm into a fixed set of mandatory positions (X) and conditions (Y); output generation is automatically blocked when any element is unmet, and any manual override triggers a non-disclosable escalation signal to the institutional supervisor, containing only metadata. We demonstrate the architecture through a polynomial decomposition of one specific Y-element — the determination of the circle of investigated persons under the Bulgarian Asset Recovery Act (ZONPI), implementing § 1, items 6, 15, 18 and 19 of its Supplementary Provisions, Articles 6, 7 and 143 of the Family Code and Article 2 of the Persons and Family Act. The polynomial is validated on a fully synthetic test family configuration designed to exercise all nine qualification members; the synthetic profile is purely illustrative and contains no personal or case-related data. The chosen example is intentionally one of the architecturally shallower components of the filter, used here to illustrate the polynomialization principle; in parallel deployment, substantively deeper components — banking pattern analysis, real estate transformation, fiscal coherence, and the determination of significant asset disparity — are similarly polynomialized but remain outside the scope of this article. The architecture is patent-protected under Bulgarian filings 114317 and 114328, with EPO/PCT/UKIPO submissions in preparation. The contribution proposes the architecture as an operational compliance mechanism that can be implemented either through institutional codes of conduct or through normative acts, depending on the procedure-specific corruption-risk profile.

    • Security evaluation metrics for an adaptive steganographic method based on the Canny algorithm

      pg(s) 26-29

      Steganography aims to conceal confidential information within digital media while minimizing perceptual and statistical distortions. Among image steganographic techniques, adaptive embedding methods have demonstrated superior resistance to steganalysis by exploiting image regions with high local complexity. One effective approach utilizes the Canny edge detection algorithm to identify suitable embedding locations. However, the effectiveness of such methods depends not only on embedding capacity but also on comprehensive security evaluation. This paper presents a systematic framework for assessing the security of an adaptive Canny-based steganographic method. Multiple objective metrics, including Peak Signal-to-Noise Ratio (PSNR), Structural Similarity Index Measure (SSIM), Mean Squared Error (MSE), histogram similarity, entropy variation, correlation coefficients, and resistance to statistical steganalysis are analyzed. The proposed evaluation framework demonstrates that edge-based adaptive embedding maintains high visual fidelity while significantly reducing detectability compared with conventional least significant bit (LSB) techniques.

  • TECHNICAL FACILITIES FOR ENSURING SECURITY

    • Modular UAV Architectures in the Support of National Weapon Integration

      pg(s) 30-32

      This study addresses tactical and technological challenges of integrating indigenous weapon systems onto UAVs in asymmetric warfare. Closed-architecture platforms impose vendor lock-in, strategic vulnerabilities, and high lifecycle costs. To resolve this, the National UAV Modular Standard (NUMS) open framework decouples hardware from proprietary software. Featuring a Longitudinal Rail System for dynamic centre-of-gravity correction, an IP68 quick-disconnect interface, and a deterministic UAVCAN/Cyphal backbone on a secure, containerized Linux OS (Mil-UAV-OS), this architecture transforms technical modularity into operational agility. Modelling shows pairing commercial off-the-shelf (COTS) components with sovereign software decreases lifecycle costs while enhancing precision. Ultimately, this ecosystem shortens the “sensor-to-shooter” timeline, enabling near-real-time tactical responsiveness. It provides a strategic blueprint for the Hungarian Defence Forces to achieve technological sovereignty, converting rigid procurement into a dynamic defence ecosystem.

    • Numerical Modeling of Smoothbore Barrel Shot

      pg(s) 33-36

      This work reports preliminary outlined relations between geometrical parameters and material parameters of smoothbore barrel and projectile during the internal stage of shot depending on the time variation of barrel pressure. Mechanical behaviors of barrel possessing diameter 18.2mm with length 760mm and projectile having cylindrical form with half-spherical form in the nose are 3-D modeled by help of the commercial Finite Element Method program product Ansys LS-DYNA. A barrel and three projectiles with different densities under five different friction conditions are numerically modeled with aims to establish both the projectile displacements and velocities, and related kinetic energy. Four stages in the projectile diagrams “Displacement-Time” and “Velocity–Time” are established correspondingly to the “Barrel Pressure –Time” diagram. Stress and strain states of barrel and projectile are reported.

      pg(s) 37-40

      The use of aircraft-type unmanned aerial vehicles (UAVaircraft type) in modern combat operations is considered. Basic temporary criteria for the production and operation of aircraft-type UAVs are defined. Using the similarity method, a determination of the mass of aircraft-type UAVs is proposed. A variant is proposed related to the calculation of the mass of the fuselage of certain aircraft-type UAV models. The difference in the use of retractable or fixed landing gear of aircraft-type UAV types in their operation is determined. Recommendations are made for noise reduction during UAV operation. The economic aspects of aircraft-type UAV design are touched upon.
