摘要
Systems and methods for detecting design-level attacks against a digital circuit which includes various functional units. A target unit is selected from among the functional units for monitoring and a predictor unit is arranged to receive events before they reach the target unit. A reactor unit is selected from among the functional units of the digital circuit which are arranged to receive events after they pass through the target unit. A monitor unit is arranged to receive predicted event messages from the predictor unit and actual event messages from the reactor unit. The monitor unit is configured to indicate an alarm based on a comparison of the predicted event messages received from the predictor unit and the actual event messages received from the reactor unit.
