Abstract
Radio frequency identification (RFID) is a technology that has grown in popularity and in the applications of use. However, there are major issues regarding security and privacy with respect to RFID technology which have caught the interest of many researchers. There are significant challenges which must be overcome to resolve RFID security and privacy issues. One reason is the constraints attached to the provision of security and privacy in RFID systems. Along with meeting the security and privacy needs of RFID technology, solutions must be inexpensive, practical, reliable, scalable, flexible, inter-organizational, and long-lasting. To make RFID identifiers effective and efficient they must identify the item(s) while resisting attacks aimed at obtaining the tag’s information and compromising the system or making it possible to bypass the protection RFID tags are supposed to provide. Different authentication methods have been proposed, researched, and evaluated in the literature. In this work, we proposed our methodology in evaluating RFID authentication, and a few of the most promising authentication methods are reviewed, compared, and ranked in order to arrive at a possible best choice of protocol to use.
Highlights
Radio frequency identification (RFID) wireless technology uses radio frequency signals to communicate between the tags which are attached to objects, and the readers, that identify the objects and are connected to a back-end server
Most people have seen RFID tags used in their everyday lives but may not have realized what the technology behind them is
Every time we go shopping we see RFID tags, they are on the items we are trying to purchase, from clothing to books to games, and even medicines
Summary
RFID wireless technology uses radio frequency signals to communicate between the tags which are attached to objects, and the readers, that identify the objects and are connected to a back-end server. The types of RFID tags used will vary based on company needs, if the company is looking to use low frequency (LF) low capacity RFID tags, the use of elliptic curve cryptography protocols may well exceed the available memory capacity on the tags In those instances, other lightweight protocols that can preserve anonymity while providing secure authentication such as those proposed by Gope in [2,3] may be a more feasible choice. All of the studied protocols use Elliptic Curve Cryptography to secure the communication between tag and reader, though each takes a slightly different approach. We will conclude and determine which of the studied methods provide the best-case implementation for RFID authentication
