RFID and Security
Stephen A. Weis, MIT Computer Science and Artificial Intelligence Laboratory
Radio frequency identification (RFID) technology has the potential to greatly impact inventory control, supply chain management, and retail sales applications by lowering costs and raising efficiency. Although some form of RFID systems has been used for decades, modern innovation and open technology standards are lowering costs to the point where it will be economical to use RFID for everyday consumer applications. By enabling digital naming of common items, RFID may facilitate an “Internet of things” by associating arbitrary data with physical objects. However, widespread adoption of RFID systems may both positively and negatively affect the security of an RFID-enabled infrastructure.
The most basic building blocks of RFID systems are small devices that broadcast identifying via radio frequency (RF) signals. These devices are called RFID transponders or tags. RFID tags are part of a greater system of RFID reading devices (or simply readers) and databases that facilitate ...
