The Design of Integrity Monitoring and Reliability Verification System for Critical Information, Transmitted in Automatic Train Signaling System, Based on DMR-RUS Radio Channel

AbstractThis article gives us results of the work on ensuring protection of critical information, transmitted in automatic train signaling system (ALS), based on DMR-RUS radio channel (special version of Digital Mobile Radio for Russian railway), against computer attacks, targeted to modification and substitution of data. The purpose of this work is development of integrity monitoring and reliability verification system (IMRVS) for information, transmitted in ALS. There are different ways of building IMRVS. This article shows one of these methods, which, in authors’ opinion, is optimal for using in ALS
