description: The purpose of the work is to study the effectiveness of using statistical tests in the problem of determining scrambler parameters, their implementation and comparison. This work is devoted to the study, implementation and comparison of various statistical methods for analyzing scrambled data. The main research tasks are: 1. Analysis of various statistical tests based on the assessment of random properties of the sequence 2. Development and implementation of algorithms for the corresponding methods in program code and their application to determine the scrambler generating polynomial 3. Design and development of a program for automatic testing of methods During the work, various tests were examined from a technical point of view. Using a program developed in C++, the methods were tested and then compared. Various methods have been applied to optimize and improve the performance. As a result, the most effective methods were identified, and various options for combining them were proposed, which may become the subject of further research to improve the effectiveness of these methods for analyzing scrambled data.
