AUTHENTICATION PROCESSING APPARATUS, AUTHENTICATION REQUESTING APPARATUS AND AUTHENTICATION EXECUTING METHOD BASED ON PHYSICALLY UNCLONABLE FUCTIONS

摘要

The present invention relates to an authentication executing method based on a physically unclonable function (PUF), capable of executing authentication by generating a response value from an output value which is outputted by generating a challenge value from state information about a wireless communication channel and inputting the generated challenge value to a PUF circuit.
