This paper propose a PUF(Physical Unclonable Function)-based IoT(Internet of Things) device authentication scheme to minimize the risk of authentication key exposure and the load of authentication server. The proposed technique can be realized by storing and updating only a single CRP(Challenge-Response Pair) through interaction with the device to be authenticated, unlike the existing technique of storing all the CRPs that can be generated by the PUF technology in the authentication server. In addition, it enables more secure device authentication through authentication message encryption by using the secret key generated from the CRP.
