Abstract: A system with fault injection attack detection can include a circuit block; at least one independent power network; a detector coupled to the at least one independent power network to detect a change in a power characteristic of the independent power network; and sensors coupled to the at least one independent power network and located in an active layer of a chip with the circuit block. The sensors are responsive to at least one type of fault injection attack. In some cases, the sensors can be inverters.
