Abstract
A method and apparatus for reading unique identifiers of an integrated circuit. The unique identifiers may be physically unclonable functions (PUFs), formed by high energy ions implanted into semiconductor material of the integrated circuit. The method may include electrically stimulating each of the PUFs and sensing measurable electrical characteristics of the PUFs. Furthermore, the method may include comparing values associated with the measurable electrical properties of the PUFs with groups of stored values in a circuit database. Each of the groups of stored values may be associated with measurable electrical properties of PUFs of a known authentic circuit. The method may also include the controller providing verification of authenticity of the integrated circuit when each of the values associated with the measurable electrical properties of the PUFs match the stored values of at least one of the groups in the circuit database.
