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.
