LIGHTWEIGHT PSEUDORANDOM NUMBER GENERATOR MODEL FOR THE INTERNET OF THINGS. (English)

The work is devoted to a rather urgent problem — the study of sequences and generators of random numbers, working on devices with limited resources, for randomness. The analysis of random sequences and random number generators is a rather specific task, but one or more of numerous test packages can be used to solve it. However, the analysis performed indicates that the existing tests have a number of drawbacks, the solution of which can reduce the prerequisites for testing and improve the accuracy of the results. The paper presents the types of random number generators and their disadvantages. Described is a lightweight and fast pseudo-random number generator useful for resourceconstrained devices such as those used in the IoT. The article is devoted to the development of lightweight pseudorandom number generators. The principles of designing a lightweight pseudo-random number generator are described. Requirements for the quality of a lightweight pseudo-random number generator are formulated. The construction of a physical model of a lightweight pseudo-random number generator was considered. The physical model of the IoT generator, which is presented in the work, by its example provides a broad overview of the factors and limitations that arise in the design of generators. The process of testing and optimizing a lightweight pseudo-random number generator is recommended using tests of multivariate statistics. These tests illustrate the suitability of the software package for use and its integral role in creating a quality random number generator, especially for use in IoT devices. The software product that was created in this work can be used to solve a wide range of tasks, as has already been repeatedly noted. One of the most important, and indeed the one that can receive invaluable benefits in the field of application, is cryptography. [ABSTRACT FROM AUTHOR]
