This investigation is relevant because of effective schemes for information and its users protection. But these algorithms is very complex and lumped. It really affects them. That's why deniable encryption algorithms have not been widespread in data processing and information security systems. The execution time reducing methods and tools exploration is the main goal of this work. The divide and conquer method has been discussed and investigated in this paper. It has been implemented into the data processing system of the deniable encryption algorithms. Nothing modifies have been implemented into the base algorithm. It allows to make it universal and apply to other deniable encryption algorithms. The series of experiments have been completed by authors to verify the hypothesis. The base deniable encryption algorithm discussing is the first stage of investigation. Its vulnerabilities have been found and investigated. Another algorithm is based on the divide and conquer method applying. It has been implemented into the modified data processing system. The both algorithms efficiency has been investigated by the experiments with the real with public and secret information files. The experiments have been completed on the prepared equipment. This equipment simulates the user's workplace with real hardware and software. According to the results the deniable encryption algorithms productivity has been reached by the divide and rule method. Also the method has been verified by the different size encryption keys. The base deniable encryption algorithms have not been modified.

An effective tool for solving this problem can be the use of dynamic models based on the provisions of catastrophe theory. This study is devoted to the analysis of modern approaches to the use of the basic provisions of catastrophe theory in cybersecurity systems.

Ateb-based Gabor filter is effective for filtration because it contains generalizations of trigonometric functions. The wavelet transform of Ateb-Gabor function was developed. The function dependence on seven parameters was shown, each of them significantly changes the filtering results of biometric images. The Ateb-Gabor wavelet research was performed. Graphic dependencies of the wavelet Gabor filter and the wavelet Ateb-Gabor filter were constructed. The appliance of wavelet transform makes it possible to reduce the complexity of calculating an Ateb-Gabor filter by simplifying function calculations and reducing filtering time. The complexities of algorithms for calculating the wavelet Gabor filter and the wavelet Ateb-Gabor filter have been evaluated. Ateb-Gabor filtration allows you to adjust the intensity of the entire image, and to change certain ranges, thereby changing certain areas of the image. Biometric images should have this property, on which the minucius should be contrasting and clear. Ateb functions have the property of changing two rational parameters, which will allow to make more flexible control of filtration. The properties of the Ateb function, as well as the possibility of changing the amplitude of the function, the oscillation frequency by the numerical values of the Ateb-Gabor filter, were investigated. By using the parameters of the Ateb function, you can get a much larger range of shapes and sizes, which expands the number of possible filtration options. You can also perform filtration once, taking into account the direction of the minucius and reliably determine the sharpness of the edges, rather than perform filtration many times. The reliability of results were tested using NIST Special Database 302 and good filtration results were shown. This is confirmed by the comparison experiment between the wavelet-Gabor filter and the wavelet Ateb-Gabor function based on the PSNR signal-to-noise ratio measurement.","PeriodicalId":198390,"journal":{"name":"Cybersecurity: Education, Science, Technique","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124013990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Justification of the need to create hybrid troops to neutralize cyber threats to the Armed Forces of Ukraine and methods of its implementation on the basis of military-civilian cooperation. Materials and methods. To solve the tasks, a set of theoretical research methods was used: historical analysis and generalization of scientific literature on the research problem; structural and genetic analysis and synthesis when specifying the object and subject of research; the method of going from the abstract to the concrete; the method of analytical and comparative analysis in the analytical and comparative evaluation of the novelty of research results; synthesis and generalization - to justify the methodological and methodical foundations of the research; generalization – formulation of conclusions and recommendations regarding the continuation of further research. Result. A key hypothesis was formed that an effective tool in countering hybrid warfare can be achieved through the use of hybrid troops. Developing this hypothesis substantiates the philosophical idea of the need to create hybrid cyber armies on the basis of military-civilian formations. Foreign experience confirms the high efficiency of military-civilian formations. On the basis of the current legal acts, a method of implementation is proposed.

The article deals with the problem of ensuring the fault-tolerance of Internet services. It is becoming increasingly important due to the growth of the quantitative parameters of the functioning of information systems (users, servers, volumes of information in databases) and the level of complexity. Due to the heavy load on the servers on which the applications are deployed, there is a failure of hardware or software. The urgency of finding additional ways to ensure the fault tolerance, reliability and uninterrupted functioning of computer systems operating in real time, due to the increasing requirements for the security of running processes or objects, access to which is limited. Despite the use of existing methods for ensuring fault tolerance in cloud infrastructures, there is a problem of inconsistency between the actual availability of systems and the levels of \"fault tolerance\" (Fault Tolerance) and \"High Availability\" (High Availability) for critical and business critical web applications. Also, less attention is paid to methods of improving fault tolerance for highly loaded systems. Therefore, the search for new opportunities for scaling and load balancing when building cloud systems is of particular importance. To conduct a comparative analysis of load balancing algorithms, functional characteristics were proposed, according to which it is possible to make an informed choice of algorithms that most closely correspond to specific practical circumstances and the requirements of users and providers. The basic principles for implementing a resiliency strategy now include redundancy, diagnostics, reconfiguration, and recovery. As an additional indicator of failover control, it is proposed to apply the completeness of the booking of elements and components of the system, the completeness and reliability of the control, the probability of reserve recovery. The first two strategies assume that a system that correctly performs its functioning algorithm is safe. The safe behavior strategy for failures is used specifically for safe systems and consists in the transition of the system to a protective irreversible state in the event of a failure.","PeriodicalId":198390,"journal":{"name":"Cybersecurity: Education, Science, Technique","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132095520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach to designing of expert system on the basis of syllogisms and logic of predicates, and also a method of meaningful identification of objects of knowledge base (KB) is offered. The essence of the method is that each object of the database of the projected EU, is matched by a tuple of keywords (ToK), the significance of which is determined by experts. Thus, each database object is placed in accordance with the element of the finite fuzzy topological space of the database objects. Meaningful identification takes place on the distance between the objects of the database. The approach proposed in the work, in comparison with the decisions of other authors, has a number of advantages. Namely, it allows: to model different variants of cyber threat scenarios for CIF and their consequences; determine the contribution of each of the factors or components of the architecture of the IS CIF to the overall picture of the probability of a cyber threat to the CIF; model the interaction of all IS factors and, if necessary, visualize this interaction; calculate and further rank the values of cyber threat probabilities for CIF for specific threat scenarios; automate the processes of threat modeling through the use of developed software and significantly reduce the time for audit of threats. It is shown that the use of the method of meaningful identification allows to increase the adequacy of the models of the selected subject area, as well as to prevent erroneous introduction of the same judgments of experts and goals in the EU database, in particular by combining hierarchies of goals formed by different expert groups. It is shown that the method can also be used to find the goals of the hierarchy, the exact wording of which, according to keywords, is unknown.","PeriodicalId":198390,"journal":{"name":"Cybersecurity: Education, Science, Technique","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114696407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
