An Introduction of RFID Data Protection Scheme

Radio frequency identification (RFID) is a promising technology that transmits the information of an object to be saved on the RFID tag wirelessly by using radio waves.RFID has been used widely in industries, such as identifying objects.Utilizing RFID system will automatically manage the inventory and reduce costs for manufacturers and retailers.However, it will also bring the risk to the users and create a new type of theft in the supermarket, if the information on the RFID tag hasn't been protected.This paper introduces a practical method of data security for the RFID technology.It'll enable a RFID tag holding data with its signature to be linked to the enterprise's database of the specific product.The polynomial digital signature scheme we introduce in this paper is one of the practical security solutions that offer the strength and efficiency for the current RFID system.This scheme is the only security technology that fits resource-constrained system such as RFID without compromising the performance and usability.
