In order to enhance shared control of the secret among multiple RFID tags and to ensure secure communication through an insecure channel, we present in this paper a new idea of threshold RFID system. We extend well-known Vaudenay’s RFID privacy model (Vaudenay in Adv Cryptolo 68–87, 2007) to make the RFID system acceptable for threshold secret sharing system among n tags. To show its implementation and to resist tag compromising attack, we design an efficient threshold RFID authentication protocol based on physical unclonable functions. It is a method of distributing a secret s among a set of n RFID tags in such a way that any set of $$t (t
