AUTHENTICATION REQUEST DEVICE BASED ON PHYSICAL DUPLICATION PREVENTION FUNCTION, AUTHENTICATION PROCESSING DEVICE AND AUTHENTICATION EXECUTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an authentication request device based on physical duplication prevention function, an authentication processing device and an authentication execution method.SOLUTION: An authentication execution method based on a physical duplication prevention function generates a challenge value from status information for a wireless communication channel, inputs a challenge value thus generated to a physical duplication prevention function (Physically Unclonable Function, PUF) circuit, and performs authentication by generating a response value from an output value.
