INFORMATION PROTECTION METHOD BASED ON THE SYSTEM OF RESIDUAL CLASSES IN THE FORMATION OF TIMER SIGNALS

Abstract

The article considers information protection method based on timer signal constructions, the impulses of which are formed using the system of residual classes. The use of timer signals allows to complicate the structure of combinations, which increases their structural secrecy. The system of residual classes allows to divide integral information into a set of independent residues according to pre-selected mutually simple modules, which opens the new possibilities for building signal constructions that can be used to increase the noise immunity of data transmission.

Particular attention is given to the use of the residual class system combined with redundant modules for the formation of correction codes, which provide detection and correction of errors caused by interference, intentional influences or technical failures. The paper analyses in detail practical algorithms for applying the residual class system to form timer signal constructions, in which information is indicated in the form of pulses with a certain time interval. At the same time, the signal constructions acquire the properties of noise immunity code and structural secrecy, which to certain extent provide protection against unauthorized access due to the uncertainty of the signal structure. The properties of structural secrecy complicate the process of determining the signal structure in the event of interception of message by enemy electronic intelligence. Mathematical examples of the formation of residual vectors and the formation of timer signal constructions are given. The obtained results indicate the feasibility of using the residual class system as one of the promising areas in the design of secure communication and information and control systems, particularly in the military sector, the Internet of Things, critical infrastructure, and real-time devices.
