Abstract
An example is a method. A query challenging authenticity is received at an intellectual property (IP) block in an integrated circuit (IC) die. The query may be a query of a query-response pair. A response to the query is generated, at the IP block, using a logic built-in self-test (LBIST) circuit. The response is transmitted from the IP block. The response may be received and compared to an expected response of the query-response pair. Authenticity may be validated when the response matches the expected response.
