Abstract
Disclosed is a fault event detector configured to detect a fault injection event in an area of a chip that includes a vulnerable digital circuit. Such a fault event detector may include a bistable device that changes state at least partially in response to a presence of a fault injection event in a surrounding area of the fault event detector. Such a fault event detector may be arranged relative to a vulnerable digital circuit such that the vulnerable digital circuit is substantially located within the surrounding area of the first fault event detector.
