Abstract
Disclosed are various embodiments providing circuitry that includes camouflaged gates that each have multiple switches arranged in a predefined format. A switch at a specific position in one camouflaged gate can have a different threshold voltage than a switch at the specific position in another camouflaged gate. The logical function performed by the camouflaged gate can be based on which of the switches have a low threshold voltage and which of the switches have a high threshold voltage.
