Abstract: A secret information generation apparatus and a method for operating the secret information generation apparatus. The secret information generation apparatus includes a resistor-capacitor circuit, and a microcontroller unit including a first pin connected to an input terminal of the resistor-capacitor circuit and a second pin connected to an output terminal of the resistor-capacitor circuit, wherein the microcontroller unit is configured to transmit a digital value corresponding to a challenge to the resistor-capacitor circuit through the first pin, receive an output value of the resistor-capacitor circuit corresponding to the digital value through the second pin, convert the received value into a digital value using an analog-to-digital converter, extract one or more valid bits from the converted digital value, and then generate a response.

Abstract: Disclosed herein are an apparatus and method for authenticating an IoT device. The method, performed by the IoT device authentication apparatus, includes transmitting, by the IoT device authentication apparatus, a random number to the IoT device and encrypting, by the IoT device authentication apparatus, the random number using a previously registered first white-box cryptography value through a white-box cryptography method; generating, by the IoT device, a first device response value from a previously registered first device challenge value using a Physical Unclonable Function (PUF) and encrypting, by the IoT device, the random number, received from the IoT device authentication apparatus, using the first device response value; and performing, by the IoT device authentication apparatus, authentication of the IoT device by checking whether the random number encrypted using the white-box cryptography method matches the random number encrypted using the PUF, which is received from the IoT device.

Abstract: Disclosed herein are an apparatus and method for device authentication. The method for device authentication based on a certificate using a PUF, performed by an apparatus for device authentication based on a certificate using a PUF, includes acquiring previously stored first Challenge-Response-Pair (CRP) information corresponding to identification information received from a device that requests authentication and generating a certificate including a public key generated using the first CRP information; transmitting a message in which the certificate encrypted using the first response value of the first CRP information as a server secret key and the first challenge value of the first CRP information are included to the device; and authenticating the device by verifying an encrypted signature message received from the device through a secure channel.
