Abstract
Embodiments of a method, an IC device, and a circuit board are disclosed. In an embodiment, the method involves at an IC device of the system, monitoring activity on a bus interface of the IC device, wherein the bus interface is connected to a bus on the system that communicatively couples the IC device to at least one other IC device on the system, applying machine learning to data corresponding to the monitored activity to generate an activity profile, monitoring subsequent activity on the bus interface of the IC device, comparing data corresponding to the to subsequently monitored activity to the machine learning generated activity profile to determine if a system-level Trojan is detected, and generating a notification when it is determined from the comparison that a system-level Trojan has been detected.
