Peculiarities of Cryptographic Model of the System of Wireless Remote Control

Abstract

The purpose of the research is to develop a cryptographic model of protection from unsanctioned influence on the process of remote control of an object through wireless exposed channels of communication. In order to achieve this goal, we developed a hybrid probabilistic model of cryptographic transformations of codes of controls, transferred through exposed channels from one or several control units. The developed cryptographic models of such distributed systems will ensure solution of the following tasks: firstly, encryption of the same code of control action is changed unpredictably in each following session of communication; secondly, the procedure of authentication of incoming cryptograms is conducted instantaneously – before the stage of decryption of the cryptogram. The first task is solved by application of a hybrid probabilistic model of cryptographical transformations, second – by means of using a specially developed structure of cryptogram that allows applying direct analysis of several one-bite requisites of cryptogram to obtain correct data on authenticity of the author of cryptogram.
