“…the output of the number outside the operating [0, М) range [28][29][30] would not take place. A significant disadvantage of methods of error detection in MNS is the need for significant time and hardware costs in the implementation, which causes significant unproductive computing costs [31][32].…”

A method for error control in the modular number system (MNS) based on the use of the zeroing procedure is proposed. Error control in the MNS is a non-positional operation and requires the development of special methods, designed to increase the efficiency of this procedure. This method is designed to verify the correct implementation of the computing process of computer systems and components. It is assumed that the error in one module remainder does not affect the residual values corresponding to other modules (bases) of the MNS. The essence of the method of error control is to use the procedure of pair number zeroing with the preliminary fetching of digits. This makes it possible to increase the efficiency of information control, presented in the modular number system. The practical significance of the results obtained is that, in comparison with the existing methods of error control in MNS, the error detection time is more than halved.

“…One of the critical indicators of stream ciphers is cryptographic resistance -a maximum period generating pseudorandom sequences, as the availability period of a pseudorandom sequence is a significant drawback to the statistical random sequences. For example, if a cipher has a small generation period, then it is evident that its value may be easily predicted; hence, the sequence period should be large and much larger than the expected length of the open message [15].…”

This paper presents the results of the comparative analysis of safety statistics and performance of encryption, the Strumok stream symmetric cipher (proposed for the national encryption standard of Ukraine) with other known cryptographic transformation algorithms, such as SALSA20, SNOW2.0, HC, AES with usages in stream mode, etc. They are accepted as national, international standards or are presented by the New European Schemes for Signatures, Integrity, and Encryptions (NESSI), Cryptography Research and Evaluation Committees (CRYPTREC) and others. The result of safety statistics is an analysis of the cryptographic properties of the output sequences using statistical test sets developed by the National Institute of Standards and Technology (NIST STS) and the DIEHARD tests. The result of the study of performance is the evaluation of the use of central processing unit (CPU) time to convert one octet of data to 64-bit computing platforms, following the test profile used in the eSTREAM contest.

“…Складність завдань, які вирішуються сучасними системами і засобами обробки цілочисельної інформації (ЗОІ), обумовлює до них підвищені вимоги щодо якості обробки інформації [1][2][3][4][5][6][7][8]. Рішення широкого кола складних обчислювальних задач вимагає (наприклад, реалізація асиметричних криптографічних алгоритмів, оптимізація обчислень в теорії сигналів та шумостійке кодування [4,[8][9][10][11], реалізація симетричних крипто-примітивів [12][13][14][15][16][17][18] та багато іншого [19][20][21][22]) значних обсягів розрахунків, які проводяться в реальному часі функціонування ЗОІ. В цьому аспекті пошук методів і засобів підвищення продуктивності обробки цифрової інформації, є актуальним [23][24][25][26][27][28][29][30].…”

Based on the properties of the class of residues in the article, a mathematical model of the process of tabular implementation of modular multiplication was synthesized, for both positive and negative numerical ranges of information processing by means of integer information processing. This model is recommended for practical application in the development of methods and algorithms for rapid processing of cryptographic information. Finding ways to simplify the structure of the table operating device integer information processing has led to the need to improve the mathematical model, methods and algorithms for modular operations, which increase the efficiency of the use of table arithmetic in the class of residues. A feature of the implementation of this model is the possibility of reducing the number of equipment operating device integer information by reducing the (50-70)% of logical elements "And" in the nodes of the table permanent storage device, directly implement the operation of modular multiplication by arbitrary mi module residual class. This is possible by using the symmetry properties of the aibi (mod mi) implementation table of the modular multiplication operation.
