Designing an algorithmic formalization of threat actions based on a Functioning table

In today’s world of information technology, information security is an important issue. In addressing information security issues, identification of attacks on the system, search for countermeasures to eliminate them, analysis of the causes of attacks, algorithmic review and algorithmization are carried out.Attacks were taken as an example in the analysis of attacks. Issues such as traffic changes and packet overload are investigated in the origin of attacks. Processes can be fully described through algorithmization in research. Identifying a specific set of information security threats by analyzing Functioning tables for algorithmic models and synthesizing and verifying incoming and outgoing data in their different versions allows any complex protection to be achieved through algorithmic descriptions. This is especially noteworthy.The diversity of system blocks means their ability to grow automatically to increase data size and provide redundant data protection. Therefore, additional safety precautions should be taken, as this article discusses the use of certain types of Functioning tables.
Image Transformation based on Computer Vision to detect Multilingual Sign Board

Text written in Urdu is cursive and belongs to the same non-Latin family as Arabic, Chinese, and Hindi. Recognizing individual ligatures in natural scene photographs is difficult due to the difficulty of detecting and localizing Urdu text. The computer vision challenge of text recognition in photographs of natural scenes is difficult. Variations in text size, color, font, orientation, backdrop, illumination, and uneven lighting make text recognition in photos of natural scenes more difficult than optical character recognition (OCR). As a solution to the issue of identifying Urdu, Hindi, and English text in natural scenes, we propose using an Image Transformation technique in this piece of study. Text recognition in Urdu is more challenging than it is with non-cursive scripts due to a variety of factors, including different writing styles, many versions of the same letter, stretched and linked text, ligature overlapping, diagonal text, and condensed text. Implementing deep learning models for word recognition in natural scene photographs can benefit from the proposed image transformation techniques, which include rotation, translation, resizing, perspective transform, cropping, dilation/erosion, and Region of Interest (ROI) selection.

Problem of Synthesis of Minimal Forms of Logical Functions

In this paper, we consider special classes of corrective functions, sets of heuristic algorithms that allow errors in the calculation of elementary properties. The article solves the problem of logical separability for the correcting functions of multivalued logic. For not everywhere defined functions, the simplest, in a sense, extensions to the entire set are constructed in such a way that these extensions are everywhere defined functions of many-valued logic. When solving a wide class of practical problems, the algorithms are often used that allow errors in calculation of elementary properties or refusals to solve problems. In such cases, several incorrect algorithms are usually applied to solve a single problem, and then a corrective function is constructed. Since the result of computing an elementary property can be either a refusal to calculate, or the property is satisfied, or the property is not satisfied, the corrective function is a function of a threedigit logic. For substantive reasons, the set of corrective functions should be limited. The problem of constructing an optimal corrector for heuristic algorithms is outlined in the paper. The aspect of corrective function continuation is considered. The problem is solved on selecting all the vertices of the grids not included into the definition domain of a previously constructed correctors.

Nonlinear transformations of different type features and the choice of latent space based on them

The problem of forming a latent feature space through nonlinear transformations of different type features is considered. Two types of transformations are used: the replacement of gradations of nominal features by the values of the function of objects belonging to classes and the combination of features according to the rules of hierarchical agglomerative grouping. The dimension of the new latent space is less than the original one and it is determined by the grouping algorithm. The ordering of latent features in relation to informativeness allows solving the problem of the curse of dimensionality and visualizing data taking into account the description of class objects.A comparative analysis of linear and nonlinear methods for reducing the dimension of space is given. The division of methods using the division of objects into classes and without such division is given. Without division into classes, the PCA and T-SNE methods are implemented on data in interval measurement scales.Using the method of calculating generalized estimates of the objects it is doing their visualization according to a certain set of different type features.

The local analysis in the directed enumeration algorithm is investigated and its algorithmic complexity is estimated.
Analysis of the Bigrams of the Letters of the Uzbek Alphabet for Cryptanalysis

The development and development of means and methods of cryptography is directly accompanied by the development of cryptanalysis methods. The classical and one of the first methods of cryptanalysis is the frequency method. Historically, the first traces of frequency analysis of the text can be found in the works of scientists since the 10th century. And here the scientists of the East, such scientists as al-Kindi, made a great contribution to cryptanalysis. This paper presents an analysis of the frequencies of bigram of letters of the text in the Uzbek language. It should be noted that at the moment the Uzbek language is based on two alphabets, namely the Latin alphabet and the alphabet based on the Cyrillic alphabet. And now further changes in the alphabet of the Uzbek language are being considered. Determining the frequencies of bigram of the letters of the Latin alphabet of the Uzbek language is accompanied by difficulties associated with the fact that some letters are combinations of letters from the original alphabet and a symbol that is not in the alphabet, for example, the letter ‘ch’. Here the letter ‘h’ belongs to the given alphabet, but the letter ‘c’ does not. And this, in turn, leads to problems in the definitions of bigrams. Based on this, texts in the Uzbek language are analyzed here using the Cyrillic alphabet, where each letter corresponds to one character. Literary work is used as content. Based on this, in this article we present the results of determining the frequencies of bigram of letters of the Uzbek language based on the Cyrillic alphabet.

To improve the security and reliability of remote terminals under trusted cloud platform, an identity authentication model based on DAA optimization is proposed. By introducing a trusted third-party CA, the scheme issues a cross domain DAA certificate to the trusted platform that needs cross domain authentication.
