RFID systems have already used in less sensitive application such as manufacturing since the use of RFID technology increases
the efficiency of a work. According as researchers are interested in RFID systems gradually, RFID systems will be applied
to various fields than before. One of RFID application fields, a bank system uses RFID tagged banknotes(tagged banknotes)
in order to prevent illegal transactions such as counterfeiting banknotes and money laundering. Several researchers have proposed
RFID schemes which are able to apply in RFID-based bank systems [2,5,10]. Unfortunately, the proposed schemes did not provide
privacy protection of individuals since sensitive information about individuals’ location is revealed by an adversary despite
one of basic requirements in RFID systems. We propose a RFID scheme for protecting location privacy of a banknote holder in
RFID-based bank systems.

    ABSTRACT: The use of RFID tags (radio-frequency identification tags) in banknotes presents a main challenge that may discourage their usage: how to avoid a possible attacker to count the amount of tags. Such a drawback is faced in this paper by designing an appropriate Medium Access Control (MAC) for this scenario. A MAC is the set of mechanisms and protocols that allows devices to share the communication channel. In a RFID system, a MAC protocol makes it possible for several tags to communicate within a common environment with the RFID reader. In this paper, we present a new MAC protocol that is suitable for ensuring security in the use of RFID-enabled banknotes. It also guarantees privacy and fits scalability requirements when the number of tags is increasing.
