The security of digital Integrated Circuits (ICs) is essential to the security of a computer system that comprises them. A particularly pernicious attack is the insertion of a hardware backdoor, that is triggered in the field using a timer that is also inserted in the hardware. Prior work has addressed deterministic timer-based triggers—those that are designed to trigger at a specific time with probability.
