- Active IC Metering Example (Hardware Security): Indented serial numbers.
- Routing Perturbation Effect (Split Manufacturing): Confuses attackers by modifying paths.
- Primary Goal of Split Manufacturing: Protect design confidentiality.
- Backend Layered-Operation: Back-end of line.
- Physical Unclonable Function (PUF): Passive unclonable metering.
- SAT Attack (DIP): Distinguishing Input Pattern.
- Output Corruptibility in Logic Locking: Assess output errors with incorrect keys.
- Dummy Branches (In Split Manufacturing): Reduces power consumption.
- Passive IC Metering Challenge (Example): Ease of cloning serial numbers.
- Anti-SAT Logic Locking Feature (Example): Weak DIPs.
- Netlist Obfuscation in Split Manufacturing Goal: Hides design structure.
- Logic Locking Effect (Clique Size): Increases power usage and reduces key interdependence. Makes circuit harder to break.
