Abstract
The present disclosure relates to an integrated circuit and a method of using the integrated circuit used to perform authentication using a challenge-response method. The challenge-response method includes an internal challenge generator, a physically unclonable function (PUF) block, and a response generator. The internal challenge generator is configured to receive a challenge, generate a plurality of internal challenges corresponding to the challenge, and generate at least one valid internal challenge among the plurality of internal challenges using screen information. The physically unclonable function (PUF) block is configured to generate a plurality of valid internal responses respectively changing according to the plurality of valid internal challenges. The response generator is configured to output a response generated using the plurality of valid internal responses.
