Covert channel detection device based on error identification in the tested nodes of automated systems

摘要

FIELD: information technology.SUBSTANCE: covert channels detection unit is introduced into the covert channels detection device, containing the informational input, the selection module of the covert channel parameters, the error detection module artificially caused by the bookmarking devices operation or resulting from the unauthorized actions of the bookmarking devices, and the signaling module for detecting the covert channel, the informational output, wherein the input of the error detection module is connected to the output of the voltage comparator, and the output of the selection module of the covert channel parameter is connected to the output of the error detection module, which output is connected to the covert channel detection signaling module input.EFFECT: covert channels detection, based on the errors identification, artificially caused in the bookmarking devices operation or arising as the result of the bookmarking devices unauthorized actions in the testable units of the automatized systems.2 dwg
