The above diagram is from the IC Activation (locking/unlocking) slide of Fighting against theft, cloning and counterfeiting of integrated circuits by Lilian Bossuet Associate Professor, CNRS Chaire of Hardware Security

How can a designer (so I guess who just creates the HDL RTL description) create something in netlist to provide a "Remote IC activation system" that will be used to UNLOCK the device after manufacturing? I mean, how can designer be sure to authorize only legit ones? How is performed?Why cloned cant?

I mean, the PUF is available/created only after manufacturing, so how can designer know the PUF in advance to authorize that device? How is performed? Why a illegal fab can't create uncloned one and can't be authorized? What is preventing it?

How can a designer be sure to authorize only legit ICs? How is performed? How are cloned ICs prevented to be activated?
