Abstract

In the article explores the general mathematical characteristics of the application of logical operations and table replacement. The sufficient conditions for the cryptographic stability of the transformation by the properties of the truth table of logical operations and table replacement are established. Some definitions are introduced that express the features and properties of the truth table. The sufficient conditions for the stability of the transformation are formulated in the form of theorems and statements.
