Application of commutative rings with unity for construction of symmetric encryption system

A method for constructing a symmetric cryptosystem based on the properties of finite associative-commutative rings with unity is proposed. Algorithms with polynomial time and memory complexity for constructing addition and multiplication tables for these rings are presented. Examples of using this system, as well as its extension by the model of a mathematical safe for subscriber identification are considered. Conditions for using the discrete logarithm function in rings are provided. The advantages of the graph task of the safe in comparison with the matrix task are shown. © 2022, Springer Science+Business Media, LLC, part of Springer Nature.
