Construction and Analysis of Models of Increasing Reliability for Modular Encryption Algorithm

Abstract

This paper describes the development of a model of symmetric block encryption algorithm using nonpositional polynomial notation systems. Computer model this algorithm was created and its properties were investigated. In order to increase the cryptostrength of the algorithm simple substitution and gamming cipher modes were used, methods of the application of these modes are shown. As a continuation of this work, a computer model for managing keys in the encryption algorithm is being developed
