Redundant modular codes for development of fault-tolerant systems of satellite identification

Abstract

Hydrocarbon production in the Extreme North on unattended facilities is based on low earth orbit satellite (LEOS) systems for communications. Their information security can be improved by means of Identification-Friend-or-Foe (IFF) system for satellite. Authentication protocol based on modular codes(MC) makes it possible prior to communicating session to determine satellite status at minimum time consumptions. Such result is achieved due to parallel computations based on MC. However, MC can also detect and correct errors. Therefore, development of authentication protocol, where redundant MC are used for correction of errors occurring upon calculation of response to request from identification system, is an urgent problem. This work is aimed at improvement of fault tolerance of satellite identification system by means of the developed authentication protocol, where redundant MC are used for correction of errors occurring upon calculation of response to request from interrogator
