Stabetska T. Methods and means of synthesis of operations of expanded matrix cryptographic transformation of arbitrary number of arguments

Thesis is dedicated to improving the quality of encryption systems through the use of expanded matrix cryptographic transformations of arbitrary number of arguments. For this purpose, the method of synthesis of operations of expanded matrix cryptographic transformation of arbitrary number of arguments based on the method of synthesis of operations of expanded matrix cryptographic transformation of three arguments was developed, the method of synthesis of inverse operations of expanded matrix cryptographic transformation of arbitrary number of arguments was developed, on the basis of synthesized operations of expanded matrix cryptographic transformation of arbitrary number of arguments, is improved The method of implementing the extended matrix cryptographic transformation operations for computer cryptography based on the use of more new synthesized operations of the extended matrix cryptographic transformation by their random synthesis, provided an opportunity for their application at the program level and made it possible to evaluate the results of its application.
