A framework for assessing RFID system security and privacy risks

The Radio Frequency Identification systems (RFID) is a powerful technology with numerous application possibilities, but it is also a technology that raises serious privacy and security risks. RFID-based systems are subject to generic attack that threaten system security and user privacy, like all information systems and there are also many attacks that specifically target RFID system technologies. The countermeasures are to encrypt the data and to use a metal screen to shield the tag and reader during information exchange. The communication looks as if the legitimate tag and the reader are close to each other, when in fact they are communicating through the communication channel that the attackers have established. The tag cloning, attackers make a duplicate RFID tag, which might either be quite similar in size or much larger than the original but have the same functionality.
