A Survey on Implementing Public Key Cryptography on RFID Tags

Radio Frequency Identification (RFID) is an emerging technology, which brings enormous productivity benefits in applications, where objects have to be identified automatically. This paper presents issues concerning security and privacy of RFID systems. RFID tags are a new generation of barcodes with added functionality. The risk related to using the tags for several applications. In particular if no appropriate cryptography measures are taken, the privacy of a user carrying tagged items can be severely damaged. To enable these applications and at the same time minimize the risks, Public Key Cryptography (PKC) offers attractive solution. We focus on the problem of anti-counterfeiting measures that can be provided by RFID tags. PKC –based identification protocols are useful for this application.
