Comment:

 The last time I checked a single production run at a semiconductor fab
 costed about 1 million USD (TSMC pricing mid-2000s, at 0.13 micron), and
 the initial yield was < 1%.  This is not anything remotely affordable.

 protected on the chip layer.

 Is incorrect, in light of dopant-level subversion done at fabrication
 time. "Stealthy Dopant-Level Hardware Trojans" (Georg T. Becker, Francesco
 Regazzoni, Christof Paar, Wayne P. Burleson).
