AUTHENTICATION REQUESTING APPARATUS, AUTHENTICATION PROCESSING APPARATUS, AND AUTHENTICATION EXECUTION METHOD BASED ON PHYSICALLY UNCLONABLE FUNCTION

摘要

Disclosed herein are an authentication requesting apparatus, an authentication processing apparatus and an authentication execution method based on a physically unclonable function (PUF). The authentication requesting apparatus includes a signal transmission and reception unit, a response generation unit, and an authentication request unit. The signal transmission and reception unit receives a first pilot signal from an authentication processing apparatus that processes authentication. The response generation unit generates a challenge value based on the first pilot signal, acquires an output value by inputting the challenge value into a PUF circuit, and generates a response value from the output value. The authentication request unit requests authentication by transmitting the response value to the authentication processing apparatus, receives authentication result information from the authentication processing apparatus, and determines whether authentication has been successful.
