1. A method comprising:
energizing a first conductive mesh of a semiconductor package to provide a wireless transmission by providing a first signal to a first terminal of the first conductive mesh;
capturing, by a second conductive mesh of the semiconductor package, a radiance produced by the wireless transmission to provide a second signal;
determining a signature of the second signal;
generating, by a cryptographic security parameter generator of the semiconductor package, a cryptographic security parameter based on the signature;
receiving a third signal received from a second terminal of the first conductive mesh;
responsive to the third signal, detecting physical tampering with the semiconductor package; and
performing a responsive action responsive to the detection of the physical tampering.
