Profile-Based Monitoring for Dual Redundant Systems

A redundant processing system with profile-based monitoring is disclosed. In embodiments, the redundant system includes two or more redundant lanes, each lane having equivalent processing components. In a testing state, template processors and hardware monitoring sensors are connected to a selected trusted lane and input vectors submitted thereto; the hardware sensors characterize the response of the selected lane and the resulting testing data compiled into system templates. In an operational environment, the template processors send challenges based on the input vectors to each of the redundant lanes in real time, collecting response data from each lane via identical sets of monitoring sensors. The template processors correlate the response data with the corresponding system templates, identifying anomalous lanes and system anomalies based on discorrelations between the response data and the system templates.
