Some progress has been made in understanding vulnerabilities and ways of reducing cyber risk at the sub-sectoral level. While the sectoral level remains a significant challenge, this study goes beyond, also addressing cyber risk resulting from the cross- and multi-sectoral interdependencies in a consistent logical model. The paper presents the scope of this logical model, outlines the problem of risk assessment, structured around the triplet &amp;ldquo;Threats &amp;ndash; Vulnerabilities &amp;ndash; Impact,&amp;rdquo; and the structuring of risk mitigation around types of risk reduction measures, the objective of decision-making on risk treatment, and the modalities of application.

Situational awareness is a tool to counteract the campaigns of malicious information and reduce its dissemination. This article proposes a conceptual model for a cyber defence awareness system, which aims to support human operators to avoid this type of threat. The system will identify (classify) three campaign types of malicious information operations – malicious information injections in web content, malicious information injections in fake social network accounts, and malicious information dissemination via email messages. A model for identification of the type of campaign of malicious information operations based on Dempster-Shafer evidence theory is proposed. The work presented here is a part of the Cyber Rapid Analysis for Defence Awareness of Real-time Situation - CyRADARS project.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><section><style face="normal" font="default" size="100%">182</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Nikolai Stoianov</style></author><author><style face="normal" font="default" size="100%">Andrey Ivanov</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Public Key Generation Principles Impact Cybersecurity</style></title><secondary-title><style face="normal" font="default" size="100%">Information &amp; Security: An International Journal</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cybersecurity</style></keyword><keyword><style  face="normal" font="default" size="100%">Miller-Rabin primality test improvement</style></keyword><keyword><style  face="normal" font="default" size="100%">Public Key Cryptography</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2020</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">47</style></volume><pages><style face="normal" font="default" size="100%">249-260</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Public key cryptography algorithms are based on number theory laws and principles. For every cryptography system one of the most important is-sues is the user’s key which he/she uses to encrypt the messages. That is the reason the key generation process is always fundamental for data protection and, since cryptography takes up more space in our daily lives, the public key generation principles are so important.

The increased interconnectedness among devices, people, networks, and systems, however, introduces a level of complexity surpassing the experience accumulated so far. While the security of communications, network and information systems can be considered a well-established discipline, the study of security of cyber-physical systems is fairly recent. Furthermore, the dependencies of live organisms, including humans, with integrated sensors and electronics, of perceptions and cognition, and variety of drones on influences from cyberspace have been subject of only few, mostly incidental studies. The interdependencies among cyber, physical, biological systems, and humans in situation assessment and decision-making roles create new potential vectors of attack by malicious actors. If exploited, they will lead to cross impact among domains that are usually studied separately. Authors from three Bulgarian institutions, combining research and policy-making experience, embarked on the task to elaborate a comprehensive cybersecurity research agenda. This paper presents their concept for an integrative approach to the exploration of &amp;lsquo;systems of systems.&amp;rsquo; The study is structured along five domains: communications and information systems and networks; cyber-physical system; bio-integrated systems; cognitive processes, i.e. the processes of shaping perceptions, assessing a certain situation and options and making decisions; and drones, remotely controlled or autonomous, the latter case being particularly reliant on advances in artificial intelligence. This paper outlines the problem of vulnerability of each of the five domains to influences from cyber space. Then it presents some advances in cross-domain understanding of vulnerabilities, supported by examples of cybersecurity studies, and provides the outlines of a corresponding, interdisciplinary research agenda, built around the concept of systems of systems. The authors conclude by predicting that the field of cybersecurity will be subject to considerable growth in coming years, requiring multi-and inter-disciplinary competencies and scientific support. &amp;copy; 2019, Curran Associates Inc.

Providing security of ICT infrastructures and protection of essential services against cyberattacks is becoming increasingly important. Several countries already have dedicated cybersecurity research programs. Bulgaria is not among those countries, notwithstanding the grave problems it faces, as emphasized by the recent leakage from the National Revenue Service exposing the personal data of almost all tax-paying citizens.

The exploration serves to span comprehensively the scenario space.

Policies for security and resilience of modern societies to threats and risks from the cyberspace account for foreseen cyber threats, their immediate impact on ICT infrastructure, consequent effects on critical services, as well as cascading effects across systems and infrastructures. This paper presents the architecture used to plan and, consequently, manage cybersecurity research in Bulgaria. It covers five application areas (information management systems; industrial control systems; unmanned and remotely piloted vehicles; bio-integrated systems; and cognitive processes and decision-making), the study of systems of systems, and support to the formulation and implementation of cybersecurity policy.</style></abstract><section><style face="normal" font="default" size="100%">93</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">E.

Many examples are available such as the national electrical grid, oil and natural gas systems, telecommunication and information networks, transportation networks, water systems, and banking and financial systems. Keeping them in reliable and secure state and study their dependencies is paramount for every government or organization. There is an urgent need of their classification. Creation and development of model and methodology which could describe their behaviors is going to make this world safer. The presented here model and based on it study and initial results are steps toward reliable and secure critical information infrastructure.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Dobrin Mahlyanov</style></author><author><style face="normal" font="default" size="100%">Nikolai Stoianov</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Security of Internet of Things – IoT</style></title><secondary-title><style face="normal" font="default" size="100%">Eighth International Scientific Conference ‘HEMUS-2016’</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year></dates><pages><style face="normal" font="default" size="100%">III217 - III-225</style></pages><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">D.
