Abstract: A process includes receiving a given reset indication to reset a semiconductor package. The given reset indication is one of a time sequence of recent indications received by the semiconductor package. The semiconductor package includes a hardware root-of-trust. The process includes detecting an activity that is associated with the semiconductor package consistent with a tampering activity. The process includes governing a response of the semiconductor package to the given reset indication responsive to the detection of the activity.

Abstract: A process incudes generating, by a canary circuit of a semiconductor package, an output value. The semiconductor package includes a hardware root-of-trust engine for an electronic system. The process includes comparing, by the canary circuit, the output value to an expected value. The process incudes, responsive to a result of the comparison, regulating, by the semiconductor package, a response of the electronic system to a reset request.
